Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This U.S. National stage application claims priority under 35 U.S.C. § 119(a) to Japanese Patent Application No. 2009-254309, filed in Japan on Nov. 5, 2009, the entire contents of which are hereby incorporated herein by reference. 
     TECHNICAL FIELD 
     The present invention relates to an indoor unit of an air conditioning apparatus. 
     BACKGROUND ART 
     As an indoor unit of an air conditioning apparatus, there is, as described in Japanese Patent Publication No. 2002-349892 for example, an indoor unit of an air conditioning apparatus where plural air outlets are disposed. In this indoor unit of an air conditioning apparatus, a wide range of a target space can be conditioned by conditioned air blown out from each of the plural air outlets. 
     However, in the indoor unit of an air conditioning apparatus of Japanese Patent Publication No. 2002-349892, in a case where the target area to which the conditioned air from a predetermined air outlet is to be blown out is near a side wall in a room or in a case where there is a user who dislikes the sensation of a draft, a closing member or the like becomes separately necessary in order to keep the extent to which the air is blown out from that air outlet low or stop it. 
     With respect to this, in an indoor unit of an air conditioning apparatus described in Japanese Patent Publication No. 2007-285652, there is proposed a technology that reduces the volume of conditioned air blown out from a specific air outlet by causing a horizontal flap that adjusts the airflow direction of the conditioned air to rotate to block the entire air outlet. 
     SUMMARY 
     Technical Problem 
     However, in the indoor unit of the air conditioning apparatus described in Japanese Patent Publication No. 2007-285652, it is difficult to completely block the air outlet with the horizontal flap, and it is easy for a temperature difference to arise between the surface of the horizontal flap that the conditioned air strikes and the surface of the horizontal flap on the room side that air whose temperature has not been adjusted strikes. When a temperature difference arises between one surface and the opposite surface of the horizontal flap in this way, it ends up becoming easier for dew condensation to form on the front surface of the horizontal flap. 
     The present invention has been made in view of the above-described circumstances, and it is a problem of the present invention to provide an indoor unit of an air conditioning apparatus that can decrease the volume of air blown out from any air outlet of plural air outlets while suppressing dew condensation without using a new part. 
     Solution to Problem 
     An indoor unit of an air conditioning apparatus of a first aspect of the invention is an indoor unit of an air conditioning apparatus that is fixed with respect to a ceiling, the indoor unit including an indoor unit casing, airflow direction adjusting plates, and an airflow direction adjusting control unit. The indoor unit casing has an air inlet and plural air outlets. The plural airflow direction adjusting plates are disposed in the air outlet respectively. The airflow direction adjusting plates can, by rotating, adjust the airflow direction of conditioned air blown out from the air outlet respectively. The airflow direction adjusting control unit can independently adjust the rotational states of the plural airflow direction adjusting plates respectively. The airflow direction adjusting control unit causes the entire body of at least any one of the plural airflow direction adjusting plates to be positioned inside the corresponding air outlet to thereby put the airflow direction adjusting plate in an air volume reducing state in which the airflow direction adjusting plate reduces the volume of the conditioned air passing through the air outlet or a suppressing state in which the airflow direction adjusting plate suppresses the flow of the conditioned air heading from the air outlet toward the opposite side of the air inlet side. 
     In this indoor unit of an air conditioning apparatus, it becomes possible to reduce the volume of air blown out from any air outlet of the plural air outlets while suppressing dew condensation without using a new part. 
     An indoor unit of an air conditioning apparatus of a second aspect of the invention is the indoor unit of an air conditioning apparatus of the first aspect of the invention and further includes arm members. The airflow direction adjusting plates are placed away from rotating shafts in the rotation. The arm members extend from the airflow direction adjusting plates to the rotating shafts. 
     In this indoor unit of an air conditioning apparatus, the airflow direction adjusting plates are placed away from the rotating shafts, so it becomes possible to change, by rotation, position in the flow direction of the conditioned air in the air outlets. 
     An indoor unit of an air conditioning apparatus of a third aspect of the invention is the indoor unit of an air conditioning apparatus of the first or second aspect of the invention, wherein the airflow direction adjusting plates have dew condensation suppressing surfaces that have a dew condensation suppressing function as a result of having a groove shape formed therein or being flocked. Back surfaces of the dew condensation suppressing surfaces of the airflow direction adjusting plates have a flatter shape than the dew condensation suppressing surfaces. 
     In this indoor unit of an air conditioning apparatus, the formation of dew condensation can be suppressed by the dew condensation suppressing surfaces of the airflow direction adjusting plates. Further, the back surfaces of the dew condensation suppressing surfaces have a flat shape, so by putting these surfaces in a state in which they face the room side, the design can be improved. For this reason, it becomes possible to achieve a balance, simply by changing the rotational states of the airflow direction adjusting plates, between suppressing dew condensation on the airflow direction adjusting plates and improving the design when seen from the room side. 
     An indoor unit of an air conditioning apparatus of a fourth aspect of the invention is the indoor unit of an air conditioning apparatus of the third aspect of the invention, wherein the dew condensation suppressing surface sides of the airflow direction adjusting plates have a concave shape, and the back surface sides of the dew condensation suppressing surfaces of the airflow direction adjusting plates have a convex shape. 
     In this indoor unit of an air conditioning apparatus, in the case of adjusting the airflow direction with the airflow direction adjusting plates, the conditioned air passing through the air outlets can be gently guided in the traveling direction, and in the case of reducing the air volume in the air outlets, it becomes possible to suppress the extent of turbulence in the traveling direction of the conditioned air. 
     An indoor unit of an air conditioning apparatus of a fifth aspect of the invention is the indoor unit of an air conditioning apparatus of any of the first to fourth aspects of the invention, wherein the indoor unit is equipped with at least four sets of the airflow direction adjusting plates and the air outlets. The number of sets on which the airflow direction adjusting control unit can simultaneously execute the air volume reducing state is only one set or two sets of the four sets. 
     In the indoor unit of an air conditioning apparatus of the first to fourth aspects, if the air volume reducing state ends up being simultaneously performed in three or more sets of the four sets of the air outlets and the airflow direction adjusting plates, the volume of air passing through the section of the remaining set of the air outlets and the airflow direction adjusting plates ends up increasing too much. 
     With respect to this, in the indoor unit of an air conditioning apparatus of the fifth aspect, the number of sets on which the air volume reducing state can be simultaneously executed is restricted to two sets or less, so it becomes possible to suppress an excessive increase in the volume of air blown out from the section not taking the air volume reducing state. 
     Advantageous Effects of Invention 
     In the indoor unit of an air conditioning apparatus of the first aspect of the invention, it becomes possible to reduce the volume of air blown out from any air outlet of the plural air outlets while suppressing dew condensation without using a new part. 
     In the indoor unit of an air conditioning apparatus of the second aspect of the invention, it becomes possible to change, by rotation, position in the flow direction of the conditioned air in the air outlets. 
     In the indoor unit of an air conditioning apparatus of the third aspect of the invention, it becomes possible to achieve a balance, simply by changing the rotational states of the airflow direction adjusting plates, between suppressing dew condensation on the airflow direction adjusting plates and improving the design when seen from the room side. 
     In the indoor unit of an air conditioning apparatus of the fourth aspect of the invention, it becomes possible to selectively perform: moderately and gently guiding, in the traveling direction, the conditioned air passing through the air outlets; and reducing the air volume while suppressing the extent of turbulence in the traveling direction of the conditioned air. 
     In the indoor unit of an air conditioning apparatus of the fifth aspect of the invention, it becomes possible to suppress an excessive increase in the volume of air blown out from the section not taking the air volume reducing state.

     DESCRIPTION OF EMBODIMENT 
     A ceiling-mounted air conditioning apparatus pertaining to an embodiment of the present invention will be described below with reference to the drawings. 
     &lt;1&gt; Air Conditioning Apparatus  1   
       FIG. 1  is a schematic configuration diagram of an air conditioning apparatus  1  in which an indoor unit pertaining to the embodiment of the present invention is employed. 
     The air conditioning apparatus  1  is a type that is installed as a result of a type of indoor unit being embedded in a ceiling, has eight air outlets, and can independently rotate and control, per airflow direction adjusting plate, the angles of inclination of airflow direction adjusting plates disposed in four of the eight air outlets. The air conditioning apparatus  1  is a split type of air conditioning apparatus, mainly has an outdoor unit  2 , an indoor unit  4 , a liquid refrigerant connection tube  5  and a gas refrigerant connection tube  6  that interconnect the outdoor unit  2  and the indoor unit  4 , and a control unit  7 , and configures a vapor compression refrigerant  10 . 
     &lt;1-1&gt; Outdoor Unit  2   
     The outdoor unit  2  is installed outdoors or the like and mainly has a compressor  21 , a four-way switching valve  22 , an outdoor heat exchanger  23 , an expansion valve  24 , a liquid-side stop valve  25 , a gas-side stop valve  26 , and an outdoor fan  27 . 
     The compressor  21  is a compressor for sucking in low-pressure gas refrigerant, compressing the low-pressure gas refrigerant into high-pressure gas refrigerant, and thereafter discharging the high-pressure gas refrigerant. 
     The four-way switching valve  22  is a valve for switching the direction of the flow of the refrigerant when switching between cooling and heating. During cooling, the four-way switching valve  22  can interconnect the discharge side of the compressor  21  and the gas side of the outdoor heat exchanger  23  and also interconnect the gas-side stop valve  26  and the suction side of the compressor  21  (refer to the solid lines of the four-way switching valve  22  in  FIG. 1 ). Further, during heating, the four-way switching valve  22  can interconnect the discharge side of the compressor  21  and the gas-side stop valve  26  and also interconnect the gas side of the outdoor heat exchanger  23  and the suction side of the compressor  21  (refer to the broken lines of the four-way switching valve  22  in  FIG. 1 ). 
     The outdoor heat exchanger  23  is a heat exchanger that functions as a condenser of the refrigerant during cooling and functions as an evaporator of the refrigerant during heating. The liquid side of the outdoor heat exchanger  23  is connected to the expansion valve  24 , and the gas side of the outdoor heat exchanger  23  is connected to the four-way switching valve  22 . 
     The expansion valve  24  is a motor-driven expansion valve which, before sending the refrigerant to an indoor heat exchanger  42  (described later), can reduce the pressure of the high-pressure liquid refrigerant that has been condensed in the outdoor heat exchanger  23  during cooling and which, before sending the refrigerant to the outdoor heat exchanger  23 , can reduce the pressure of the high-pressure liquid refrigerant that has been condensed in the indoor heat exchanger  42  during heating. 
     The liquid-side stop valve  25  and the gas-side stop valve  26  are valves disposed in openings that connect to external devices and pipes (specifically, the liquid refrigerant connection tube  5  and the gas refrigerant connection tube  6 ). The liquid-side stop valve  25  is connected to the expansion valve  24 . The gas-side stop valve  26  is connected to the four-way switching valve  22 . 
     The outdoor fan  27  is placed inside the outdoor unit  2  and forms an airflow that sucks in outdoor air, supplies the outdoor air to the outdoor heat exchanger  23 , and thereafter discharges the outdoor air to the outside of the unit. For this reason, the outdoor heat exchanger  23  has the function of using the outdoor air as a cooling source or a heating source to condense and evaporate the refrigerant. 
     &lt;1-2&gt; Indoor Unit  4   
     In the present embodiment, the indoor unit  4  is a type of ceiling-mounted air conditioning apparatus indoor unit called a ceiling-embedded type and has an indoor unit casing  31 , an indoor fan  41 , an indoor heat exchanger  42 , a drain pan  40 , a bell mouth  41   c  and other components. 
       FIG. 2  is an external perspective view of the indoor unit  4 .  FIG. 4  is a schematic plan view showing a state where a top plate  33   a  of the indoor unit  4  has been removed.  FIG. 3  is a schematic side sectional view of the indoor unit  4  and corresponds to a cross-sectional view in a cross section indicated by A-O-A in  FIG. 4 . 
     The indoor unit casing  31  includes a casing body  31   a , a decorative panel  32 , and airflow direction adjusting portions  70 . 
     As shown in  FIG. 3  and  FIG. 4 , the casing body  31   a  is placed so as to be inserted in an opening formed in a ceiling U of an air-conditioned room. When the casing body  31   a  is seen from above, the casing body  31   a  is a substantially octagonal box-like body in which long sides and short sides are alternately formed, and the lower surface of the casing body  31   a  is open. The casing body  31   a  has a substantially octagonal top plate  33   a  in which long sides and short sides are alternately continuously formed, a side plate  34  that extends downward from the peripheral edge portion of the top plate  33   a , and a bottom plate  33   b  that supports the top plate  33   a  and the side plate  34  from below. The side plate  34  is configured from side plates  34   a ,  34   b ,  34   c , and  34   d , which correspond to the long sides of the top plate  33   a , and side plates  34   e ,  34   f ,  34   g , and  34   h , which correspond to the short sides of the top plate  33   a . A liquid-side connecting tube  5   a  and a gas-side connecting tube  6   a  for interconnecting the indoor heat exchanger  42  and the refrigerant connection tubes  5  and  6  penetrate the side plate  34   h . As shown in  FIG. 6 , which is a bottom view in a state where the decorative panel  32  and other components are not attached, a substantially quadrilateral opening is disposed in the center of the bottom plate  33   b , plural openings are disposed around that opening, and the bottom plate  33   b  configures a lower surface of the casing body  31   a . As shown in  FIG. 3 , the bottom plate  33   b  is formed so as to widen further outward than the top plate  33   a  and the side plate  34 , and the decorative panel  32  is attached to the lower surface side (the room side) of the bottom plate  33   b.    
     As shown in  FIG. 3 ,  FIG. 4 , and  FIG. 6 , inside the easing  31   a  are disposed an air inlet flow path  35   a  for taking in air from an air inlet  35  into the inside of the easing body  31   a  and air outlet flow paths  51   a ,  52   a ,  53   a ,  54   a ,  61   a ,  62   a ,  63   a , and  64   a  that are placed so as to surround the outside of the air inlet flow path  35   a , have shapes extending in a substantially vertical direction, and are for blowing out conditioned air into the room. 
     As shown in  FIG. 2 ,  FIG. 3 , and  FIG. 4 , the decorative panel  32  is placed so as to be fitted into the opening in the ceiling U. The decorative panel  32  is a plate-like body having a substantially quadrilateral shape as seen from above and is mainly fixed to the lower end portion of the casing body  31   a  as a result of being attached from the room side with respect to the bottom plate  33   b  of the casing body  31   a . As shown in  FIG. 5 , which is a bottom view of the indoor unit  4 , the decorative panel  32  is configured by a suction grill  32   a , an inner frame decorative panel  37 , and an outer frame decorative panel  38 , and has an air inlet  35  and an air outlet  36 . In an installed state of the indoor unit  4 , the lower end of the inner frame decorative panel  37  is placed so as to be positioned a little lower than the lower end of the outer frame decorative panel  38 . 
     The suction grill  32   a  is a substantially quadrilateral panel placed in the center of the lower surface of the casing body  31   a . As shown in  FIG. 7 , which is a bottom view seen from the room side, the inner frame decorative panel  37  is a substantially quadrilateral frame member and is placed between the air inlet  35  and the air outlet  36 . An inside edge  37   i  of the inner frame decorative panel  37  is substantially quadrilateral and has a shape whose corner sections are rounded. The outside edge of the inner frame decorative panel  37  includes inner frame air outlet-side linear portions  37   a , inner frame air outlet-side curved portions  37   b , and opening-inside bulging portions  37   c . The inner frame air outlet-side linear portions  37   a  are sections that are disposed in outside positions corresponding to the neighborhoods of the centers of the four sides of the inside edge  37   i , are substantially parallel to the sides of the inside edge  37   i , and extend linearly. The inner frame air outlet-side curved portions  37   b  are formed in such a way that their edges are positioned further outward as approaching the corners of the inner frame decorative panel  37 . The inner frame air outlet-side curved portions  37   b  have concave shapes recessed smoothly inward. The opening-inside bulging portions  37   c  configure the outer edges in the vicinities of the corners of the inner frame decorative panel  37  and have outwardly bulging shapes whose corners are rounded. The outer frame decorative panel  38  is placed so as to cover the outer edge of the lower surface of the casing body  31   a  and is placed on the outside of the air outlet  36 . As shown in  FIG. 8 , which is a bottom view seen from the room side, an outside edge  38   j  of the outer frame decorative panel  38  is substantially quadrilateral, has a shape following the edge of the bottom plate  33   b  of the casing body  31   a , and has rounded corners. The inside edge of the outer frame decorative panel  38  includes outer frame air outlet-side linear portions  38   d  and outer frame air outlet-side curved portions  38   e . The outer frame air outlet-side linear portions  38   d  are sections that are disposed in inside positions corresponding to the neighborhoods of the centers of the four sides of the outside edge  38   j , are substantially parallel to the sides of the outside edge  38   j , and extend linearly. The outer frame air outlet-side curved portions  38   e  are formed in such a way that their edges are positioned further inward closer to the corners of the outer frame decorative panel  38 . The outer frame air outlet-side curved portions  38   e  have convex shapes that bulge gently outward. The linear sections of the outer frame air outlet-side linear portions  38   d  are formed so as to be shorter than the linear sections of the inner frame air outlet-side linear portions  37   a , and the percentage of the outer frame air outlet-side curved portions  38   e  in the length along the inner frame is large, so a bottom view of the outer frame air outlet-side linear portions  38   d  and the outer frame air outlet-side curved portions  38   e  shows they have a shape close to that of a circle. 
     The air inlet  35  is a substantially quadrilateral opening disposed in the substantial center of the suction grill  32   a . A filter  39  for removing dirt and dust in the air that has been sucked in from the air inlet  35  is disposed in the air inlet  35 . The above mentioned air inlet flow path  35   a  leads to the air inlet  35  on the inside of the casing body  31   a.    
     The air outlet  36  is disposed between the inner frame decorative panel  37  and the outer frame decorative panel  38  so as to surround the periphery of the air inlet  35  and is configured from long-side air outlets  50  and short-side air outlets  60 . The long-side air outlets  50  are configured from four air outlets—a first long-side air outlet  51 , a second long-side air outlet  52 , a third long-side air outlet  53 , and a fourth long-side air outlet  54 —that are disposed in positions corresponding to the sides of the substantially quadrilateral shape of the air inlet  35 . The long-side air outlets  50  are formed so as to not have edge sections facing the inside of the opening. The long-side air outlets  50  are configured in such a way that the difference in length between their lengthwise direction and their width direction, which is a direction orthogonal to the lengthwise direction, is smaller than in a conventional air outlet (in such a way that the aspect ratio of the lengths is smaller than conventionally), so the initial speed of the airflows blown out from the neighborhoods of the centers of the long-side air outlets  50  can be raised. The short-side air outlets  60  are configured from four air outlets—a first short-side air outlet  61 , a second short-side air outlet  62 , a third short-side air outlet  63 , and a fourth short-side air outlet  64 —that are disposed in positions corresponding to the corner sections of the substantially quadrilateral shape of the air inlet  35 . The air outlet  36  is configured in such a way that the long-side air outlets  50  and the short-side air outlets  60  are alternately arranged and placed in a substantially annular shape. The first long-side air outlet flow path  51   a , the second long-side air outlet flow path  52   a , the third long-side air outlet flow path  53   a , and the fourth long-side air outlet flow path  54   a  lead respectively to the first long-side air outlet  51 , the second long-side air outlet  52 , the third long-side air outlet  53 , and the fourth long-side air outlet  54 . Further, the first short-side air outlet flow path  61   a , the second short-side air outlet flow path  62   a , the third short-side air outlet flow path  63   a , and the fourth short-side air outlet flow path  64   a  lead respectively to the first short-side air outlet  61 , the second short-side air outlet  62 , the third short-side air outlet  63 , and the fourth short-side air outlet  64 . 
     Airflows F 51 , F 52 , F 53 , F 54 , F 61 , F 62 , F 63 , and F 64  that have been conditioned inside the indoor unit  4  are blown out, while having their blow-out direction adjusted, respectively from the first long-side air outlet  51 , the second long-side air outlet  52 , the third long-side air outlet  53 , the fourth long-side air outlet  54 , the first short-side air outlet  61 , the second short-side air outlet  62 , the third short-side air outlet  63 , and the fourth short-side air outlet  64 . 
     As shown in  FIG. 10 , which is a cross-sectional view as seen in an axial direction, and in  FIG. 9 , which is an external perspective view regarding a surface mainly facing the room side, the airflow direction adjusting portions  70  have a shape that is long in an axis-of-rotation direction. The airflow direction adjusting portions  70  function as airflow direction adjusting plates that adjust the direction of the conditioned air blown out into the air-conditioned room. In the present embodiment, the airflow direction adjusting portions  70  are not placed in the short-side air outlets  60  of the air outlet  36  and are placed only in the long-side air outlets  50 . The airflow direction adjusting portions  70  include a first airflow direction adjusting portion  71  that adjusts the direction of the conditioned air blown out from the first long-side air outlet  51 , a second airflow direction adjusting portion  72  that adjusts the direction of the conditioned air blown out from the second long-side air outlet  52 , a third airflow direction adjusting portion  73  that adjusts the direction of the conditioned air blown out from the third long-side air outlet  53 , and a fourth airflow direction adjusting portion  74  that adjusts the direction of the conditioned air blown out from the fourth long-side air outlet  54 . 
     As shown in  FIG. 9 , each of the airflow direction adjusting portions  70  has a flap body  80  and an arm  90  that includes a rotating shaft  90   x.    
     The flap body  80  is a plate-shaped member formed so as to extend in a direction substantially parallel to the rotating shaft  90   x , and a front surface  80   x  that is a surface on the opposite side of a back surface  80   y  that is a surface on the side where the arm  90  is attached has a curved shape projecting outward. Because the flap body  80  has a moderately curved shape in this way, the conditioned air passing through the long-side air outlet  50  can be gently guided in the traveling direction. The outer edge of the flap body  80  is formed so as to not have a section with an inwardly recessed shape. As shown in  FIG. 10 , in a state where the front surface  80   x  is mainly facing the room side (the blow-out airflow downstream side), the flap body  80  is disposed in such a way that the distance between the flap body  80  and the rotating shaft  90   x  becomes shorter as the flap body  80  becomes closer to the room side and is disposed in such a way that the distance between the flap body  80  and the rotating shaft  90   x  becomes longer as the flap body  80  becomes away from the room side (heading toward the blow-out airflow upstream side). Because of this, in a case where the airflow direction adjusting portion  70  has rotated, the airflow direction adjusting portion  70  follows a trajectory that differs between one end and the other end of the flap body  80 . As shown in  FIG. 10 , a concavo-convexly shaped portion  80   xa  is disposed, so as to be along in the lengthwise direction of the flap body  80 , on the front surface  80   x  of the flap body  80  in a section in the neighborhood of the outside end portion in a state where the front surface  80   x  is mainly facing the blow-out airflow downstream side. Outside the section where the concavo-convexly shaped portion  80   xa  is disposed, the front surface  80   x  of the flap body  80  is configured by a smooth, substantially flat, surface. Further, a flocked sheet  80   ya  comprising a sheet in which a mixture of short fibers with different pile lengths is uniformly flocked is adhered to the back surface  80   y  of the flap body  80 . The flocked sheet  80   ya  is a section that the conditioned air from inside the casing body  31   a  strikes when adjusting the blow-out airflow direction in a state where the front surface  80   x  of the flap body  80  is mainly facing the blow-out airflow downstream side. The flocked sheet  80   ya  can suppress the formation of dew condensation on the flap body  80 . As shown in  FIG. 10 , the flocked sheet  80   ya  is disposed slightly toward the inside in a state where the front surface  80   x  is mainly facing the blow-out airflow downstream side. The flocked sheet  80   ya  is disposed in such a way that there becomes less of a section in which the flocked sheet  80   ya  and the concavo-convexly shaped portion  80   xa  overlap in the plate thickness direction of the flap body  80 . 
     Further, as shown in  FIG. 9 , which is an external perspective view seen from the front surface  80   x  side, the outer edge shape of the flap body  80  includes a flap inside linear portion  80   a , flap inside curved portions  80   b , flap lengthwise direction end portions  80   c , a flap outside linear portion  80   d , and flap outside curved portions  80   e . The flap inside linear portion  80   a  is positioned on the inside of the flap body  80  in a state where the front surface  80   x  of the flap body  80  is facing the room side. The flap inside linear portion  80   a  is the edge of a linearly shaped section extending substantially parallel to the rotating shaft  90   x  direction. The flap inside linear portion  80   a  is disposed in the neighborhood of the center of the flap body  80  in the direction of the rotating shaft  90   x  and occupies a section of about 50% of the flap body  80  in the lengthwise direction. The flap inside curved portions  80   b  are edges that gently connect the flap lengthwise direction end portions  80   c  to both ends of the flap inside linear portion  80   a  and have shapes gently bulging toward the outside of the flap body  80 . The flap inside curved portions  80   b  occupy sections of about 25% each from the lengthwise direction end portions of the flap body  80 . The flap lengthwise direction end portions  80   c  are placed in positions toward the flap outside linear portion  80   d  in the width direction orthogonal to the rotating shaft  90   x  direction, that is, in a direction orthogonal to both the flap inside linear portion  80   a  and the flap outside linear portion  80   d . In other words, in a case where the flap body  80  is seen from the front surface  80   x  side, the flap lengthwise direction end portions  80   c  are disposed in such a way that the width direction distance between the flap lengthwise direction end portions  80   c  and the flap inside linear portion  80   a  is longer than the width direction distance between the flap lengthwise direction end portions  80   c  and the flap outside linear portion  80   d . The flap outside linear portion  80   d  is positioned on the outside of the flap body  80  in a state where the front surface  80   x  of the flap body  80  is facing the room side. The flap outside linear portion  80   d  is the edge of a linearly shaped section extending substantially parallel to the rotating shaft  90   x  direction. The flap outside linear portion  80   d  is also disposed in the neighborhood of the center of flap body  80  in the direction of the rotating shaft  90   x  but is formed shorter than the length of the flap inside linear portion  80   a . The flap outside curved portions  80   e  are edges that connect, more abruptly than the flap inside curved portions  80   b , the flap lengthwise direction end portions  80   c  to both ends of the flap outside linear portion  80   d  and have shapes bulging gently outward. 
     As shown in  FIG. 10 , the arm  90  extends as far as a section beyond the rotating shaft  90   x  in a direction away from the back surface  80   y  of the flap body  80  in the neighborhoods of both lengthwise direction end portions of the flap body  80 . That is, as shown in  FIG. 10 , the length of the arm  90  is formed longer than a distance D from the back surface  80   y  of the flap body  80  to the rotating shaft  90   x . The arm  90  extends in such a way that it inclines a little more toward the outer frame decorative panel  38  side than in the plate thickness direction of the flap body  80  in a state where the majority of the front surface  80   x  of the flap body  80  can be seen when the casing body  31   a  is seen from below. As shown in  FIG. 9 , shaft members  90   a  that extend so as to follow the rotating shafts  90   x  are disposed in the neighborhoods of the end portions of the arms  90  on the opposite sides of the end portions on the flap body  80  side. The arm  90  extends from a little lower side of the back surface  80   y  of the flap body  80  in a state where the front surface  80   x  of the flap body  80  is facing the room side and has a width that is about 30% of the width, in the neighborhood of the center, of the flap body  80 . 
     The placement relationship between the long-side air outlets  50  and the airflow direction adjusting portions  70  will be described later. 
     The indoor fan  41  is a centrifugal blower placed inside the casing body  31   a . The indoor fan  41  forms an airflow that sucks the room air through the air inlet  35  in the decorative panel  32  into the casing body  31   a  and blows out the air through the air outlet  36  in the decorative panel  32  to the outside of the casing body  31   a . The indoor fan  41  has a fan motor  41   a  that is disposed in the center of the top plate  33   a  of the casing body  31   a  and an impeller  41   b  that is coupled to and driven to rotate by the fan motor  41   a . The impeller  41   b  is an impeller having turbo blades and can suck air into the inside of the impeller  41   b  from below and blow out the air toward the outer peripheral side of the impeller  41   b  as seen from above. 
     The indoor heat exchanger  42  is a fin-and-tube heat exchanger that is bent so as to surround the periphery of the indoor fan  41  as seen from above and is placed inside the casing body  31   a . More specifically, the indoor heat exchanger  42  is a fin-and-tube heat exchanger called a cross-fin type that has numerous heat transfer fins placed a predetermined interval apart from each other and plural heat transfer tubes disposed in a state where they penetrate these heat transfer fins in their plate thickness direction. As described above, the liquid side of the indoor heat exchanger  42  is connected to the liquid refrigerant connection tube  5  via the liquid-side connecting tube  5   a . The gas side of the indoor heat exchanger  42  is connected to the gas refrigerant connection tube  6  via the gas-side connecting tube  6   a . Additionally, the indoor heat exchanger  42  functions as an evaporator of the refrigerant during cooling and as a condenser of the refrigerant during heating. Because of this, the indoor heat exchanger  42  can perform heat exchange with the air that has been blown out from the indoor fan  41 , cool the air during cooling, and heat the air during heating. 
     The drain pan  40  is placed on the underside of the indoor heat exchanger  42  and receives drain water produced as a result of moisture in the air condensing in the indoor heat exchanger  42 . The drain pan  40  is attached to the lower portion of the casing body  31   a.  Outlet holes  40   a , an inlet hole  40   b , and a drain water receiving channel  40   c  are formed in the drain pan  40 . The outlet holes  40   a  are formed in various places so as to be communicated with the air outlet  36  in the decorative panel  32 . The inlet hole  40   b  is formed so as to be communicated with the air inlet  35  in the decorative panel  32 . The drain water receiving channel  40   c  is formed on the underside of the indoor heat exchanger  42 . 
     The bell mouth  41   c  is placed so as to correspond to the inside of the inlet hole  40   b  in the drain pan  40  and guides the air sucked in from the air inlet  35  to the impeller  41   b  of the indoor fan. 
     &lt;1-3&gt; Control Unit  7   
     As shown in  FIG. 1 , a control unit  7  has an outdoor control unit  7   a  that controls the various configural devices of the outdoor unit  2 , an indoor control unit  7   b  that controls the various configural devices of the indoor unit  4 , and a controller  7   c  for receiving setting inputs from a user. 
     The control unit  7  performs: independent airflow direction control that independently adjusts the airflow directions of the conditioned air blown out from four air outlets—the first long-side air outlet  51 , the second long-side air outlet  52 , the third long-side air outlet  53 , and the fourth long-side air outlet  54 —of the air outlet  36  by performing control that allows the first airflow direction adjusting portion  71 , the second airflow direction adjusting portion  72 , the third airflow direction adjusting portion  73 , and the fourth airflow direction adjusting portion  74  to be moved independently, per each airflow direction adjusting portion  70 , to thereby change their rotational states; and interlocking airflow direction control that interlockingly adjusts the aforementioned airflow direction by performing control that causes all of the first airflow direction adjusting portion  71 , the second airflow direction adjusting portion  72 , the third airflow direction adjusting portion  73 , and the fourth airflow direction adjusting portion  74  to move interlockingly so that their postures have the same rotational state. Here, the controller  7   c  has an input button and other components and receives from the user an instruction to either perform the independent airflow direction control or perform the interlocking airflow direction control. Additionally, the control unit  7  performs the independent airflow direction control or the interlocking airflow direction control in accordance with the instruction to perform the independent airflow direction control or the interlocking airflow direction control that the controller  7   c  has received. 
     In addition to the independent airflow direction control and the interlocking airflow direction control, the control unit  7  also performs, in regard to the four air outlets—the first long-side air outlet  51 , the second long-side air outlet  52 , the third long-side air outlet  53 , and the fourth long-side air outlet  54 —of the air outlet  36 , individual air volume suppression control that most reduces the volume of air blown out from a specific long-side air outlet  51  to  54  by individually independently adjusting the rotational state of each of the airflow direction adjusting portions  70  including the first airflow direction adjusting portion  71 , the second airflow direction adjusting portion  72 , the third airflow direction adjusting portion  73 , and the fourth airflow direction adjusting portion  74  to change the posture. Here, the controller  7   c  can, like described above, receive from the user an instruction to perform the individual air volume suppression control and a designation of a specific long-side air outlet  50  of the long-side air outlets  50  selected to have the volume of air blown out from that, long-side air outlet suppressed. Additionally, in a case where the controller  7   c  has received an instruction to perform the individual air volume suppression control, the control unit  7  performs the individual air volume suppression control by rotating the airflow direction adjusting portion  70  placed in the position of the specific long-side air outlet  50  in such a way that the volume of air blown out from the specific long-side air outlet  50  becomes most reduced. Here, the number of the long-side air outlets  50  whose air volumes can be suppressed by the individual air volume suppression control at the same time is two or less, and the control unit  7  prohibits the individual air volume suppression control from being performed at the same time in regard to three or more of the long-side air outlets  50 . Specifically, the control unit  7  allows the individual air volume suppression control to be continued in regard to specific long-side air outlets  50  whose designation the control unit  7  has received first and second, and the control unit  7  ignores setting inputs of the individual air volume suppression control in regard to specific long-side air outlets  50  whose designation the controller  7   c  receives thereafter. In a case where the user cancels, from the controller  7   c , the individual air volume suppression control in regard to a specific long-side air outlet  50 , the control unit  7  can then perform the individual air volume suppression control in regard to another long-side air outlet  50 . 
     &lt;Basic Actions&gt; 
     Next, the actions of the air conditioning apparatus  1  during a cooling operation and a heating operation will be described. 
     &lt;2-1&gt; Cooling Action 
     In the refrigerant circuit  10  during cooling, the four-way switching valve  22  is in the state indicated by the solid lines in  FIG. 1 . Further, the liquid-side stop valve  25  and the gas-side stop valve  26  are placed in an open state, and the opening degree of the expansion valve  24  is adjusted so as to reduce the pressure of the refrigerant. 
     In this state of the refrigerant circuit  10 , low-pressure gas refrigerant is sucked into the compressor  21 . In the compressor  21 , the low-pressure gas refrigerant is compressed and becomes high-pressure gas refrigerant. The high-pressure gas refrigerant is discharged from the compressor  21 . The high-pressure gas refrigerant is sent through the four-way switching valve  22  to the outdoor heat exchanger  23 . In the outdoor heat exchanger  23 , the high-pressure gas refrigerant performs heat exchange with the outdoor air, condenses, and becomes high-pressure liquid refrigerant. The high-pressure liquid refrigerant is sent to the expansion valve  24 . In the expansion valve  24 , the high-pressure liquid refrigerant has its pressure reduced and becomes low-pressure refrigerant in a gas-liquid two-phase state. The low-pressure refrigerant in the gas-liquid two-phase state is sent through the liquid-side stop valve  25 , the liquid refrigerant connection tube  5 , and the liquid-side connecting tube  5   a  to the indoor heat exchanger  42 . In the indoor heat exchanger  42 , the low-pressure refrigerant in the gas-liquid two-phase state performs heat exchange with the air blown out from the indoor fan  41 , evaporates, and becomes low-pressure gas refrigerant. The low-pressure gas refrigerant is sent back to the compressor  21  through the gas-side connecting tube  6   a , the gas refrigerant connection tube  6 , the gas-side stop valve  26 , and the four-way switching valve  22 . 
     &lt;2-2&gt; Heating Action 
     Next, in the refrigerant circuit  10  during heating, the four-way switching valve  22  is in the state indicated by the broken lines in  FIG. 1 . Further, the liquid-side stop valve  25  and the gas-side stop valve  26  are placed in an open state, and the opening degree of the expansion valve  24  is adjusted in such a way that the expansion valve  24  reduces the pressure of the refrigerant. 
     In this state of the refrigerant circuit  10 , low-pressure gas refrigerant is sucked into the compressor  21 . In the compressor  21 , the low-pressure gas refrigerant is compressed and becomes high-pressure gas refrigerant. The high-pressure gas refrigerant is discharged from the compressor  21 . The high-pressure gas refrigerant is sent to the indoor heat exchanger  42  through the four-way switching valve  22 , the gas-side stop valve  26 , the gas refrigerant connection tube  6 , and the gas-side connecting tube  6   a . In the indoor heat exchanger  42 , the high-pressure gas refrigerant performs heat exchange with the air blown out from the indoor fan  41 , condenses, and becomes high-pressure liquid refrigerant. The high-pressure liquid refrigerant is sent through the liquid-side connecting tube  5   a , the liquid refrigerant connection tube  5 , and the liquid-side stop valve  25  to the expansion valve  24 . In the expansion valve  24 , the high-pressure liquid refrigerant has its pressure reduced and becomes low-pressure refrigerant in a gas-liquid two-phase state. The low-pressure refrigerant in the gas-liquid two-phase state is sent to the outdoor heat exchanger  23 . In the outdoor heat exchanger  23 , the low-pressure refrigerant in the gas-liquid two-phase state performs heat exchange with the outdoor air, evaporates, and becomes low-pressure gas refrigerant. The low-pressure gas refrigerant is sent through the four-way switching valve  22  back to the compressor  21 . 
     &lt;3&gt; Placement Relationship Between Long-side Air Outlets  50  and Airflow Direction Adjusting Portions  70   
     Here, the placement of the first airflow direction adjusting portion  71  in the neighborhood of the first long-side air outlet  51  will be described. The neighborhood of the second long-side air outlet  52 , the neighborhood of the third long-side air outlet  53 , and the neighborhood of the fourth long-side air outlet  54  are the same as the neighborhood of the first long-side air outlet  51 , so description thereof will be omitted. 
     &lt;3-1&gt; Placement Relationship as Seen from Below 
       FIG. 11  is a partially enlarged external view, as seen from below, of the neighborhood of the first long-side air outlet  51 . 
     When the indoor unit  4  is seen from below, the first airflow direction adjusting portion  71  and airflow direction adjusting drive units  95  are placed on the inside of the first long-side air outlet  51 . 
     The airflow direction adjusting drive units  95  are disposed on the insides of both lengthwise direction ends of the first long-side air outlet  51  and on the outsides of both lengthwise direction ends of the first airflow direction adjusting portion  71 . The airflow direction adjusting drive units  95  are connected to the first airflow direction adjusting portion  71  via the shaft members  90   a  extending so as to follow the rotating shafts  90   x  from the arms  90  of the first airflow direction adjusting portion  71  and apply a driving force for causing the first airflow direction adjusting portion  71  to rotate. Specifically, the airflow direction adjusting drive units  95  and the shaft members  90   a  of the first airflow direction adjusting portion  71  configure unillustrated cam mechanisms, and drive control via the cam mechanisms is performed as a result of the control unit  7  sending to the airflow direction adjusting drive units  95  a control signal for causing the airflow direction adjusting drive units  95  to control the drive state of the first airflow direction adjusting portion  71 . 
     The outside edge of the first long-side air outlet  51  is configured by the outer frame decorative panel  38 , the inside edge of the first long-side air outlet  51  is configured by the inner frame decorative panel  37 , and the lengthwise direction end portions of the first long-side air outlet  51  are configured by the inside side surfaces of the airflow direction adjusting drive units  95 . The width, at the lengthwise direction end portions (the inside side surfaces of the airflow direction adjusting drive units  95 ), of the first long-side air outlet  51  is formed so as to be about 60% of the width, in the neighborhood of the lengthwise direction center, of the first long-side air outlet  51 . Specifically, the outside edge of the first long-side air outlet  51  is configured by the outer frame air outlet-side linear portion  38   d  and the outer frame air outlet-side curved portions  38   e  of the outer frame decorative panel  38 . Further, the inside edge of the first long-side air outlet  51  is configured by the inner frame air outlet-side linear portion  37   a  and the inner frame air outlet-side curved portions  37   b  of the inner frame decorative panel  37 . Because of this, the first long-side air outlet  51  has, when seen from below, a shape that bulges greatly inward while bulging a little outward. The bulging of the first long-side air outlet  51  inward is formed so as to be greater than the bulging of the first long-side air outlet  51  outward. 
     The outer frame air outlet-side linear portion  38   d  of the outer frame decorative panel  38  is positioned in the neighborhood of the lengthwise direction center of the first long-side air outlet  51 . The outer frame air outlet-side curved portions  38   e  of the outer frame decorative panel  38  are positioned in the neighborhoods of both lengthwise direction ends of the first long-side air outlet  51  and in the neighborhoods of the outsides of the airflow direction adjusting drive units  95 . 
     The inner frame air outlet-side linear portion  37   a  of the inner frame decorative panel  37  is positioned in the neighborhood of the lengthwise direction center of the first long-side air outlet  51 . The inner frame air outlet-side curved portions  37   b  of the inner frame decorative panel  37  are positioned a little inside of both lengthwise direction ends of the first long-side air outlet  51  and on the insides of the airflow direction adjusting drive units  95  and in the neighborhoods between the airflow direction adjusting drive units  95  and the first airflow direction adjusting portion  71 . 
     The horizontal direction width between the flap outside linear portion  80   d  and the flap outside curved portions  80   e  configuring the outside edge of the flap body  80  of the first airflow direction adjusting portion  71  and the outer frame air outlet-side linear portion  38   d  and the outer frame air outlet-side curved portions  38   e  of the outer frame decorative panel  38  configuring the outside edge of the first long-side air outlet  51  is placed so as to be substantially the same width (about 2 cm) across in the entire lengthwise direction of the first long-side air outlet  51 . 
     The horizontal direction width between of the flap inside linear portion  80   a , the flap inside curved portions  80   b , and the flap lengthwise direction end portions  80   c  configuring the inside edge of the flap body  80  of the first airflow direction adjusting portion  71  and the inner frame air outlet-side linear portion  37   a  and the inner frame air outlet-side curved portions  37   b  of the outer frame decorative panel  38  configuring the inside edge of the first long-side air outlet  51  is placed so as to be substantially the same width (about 1 cm) across in the entire lengthwise direction of the first long-side air outlet  51  so that the mutual edges follow each other. 
     The width between the inside edge of the flap body  80  of the first airflow direction adjusting portion  71  and the inside edge of the first long-side air outlet  51  is configured to be equal to or less than half of the width between the outside edge of the flap body  80  of the first airflow direction adjusting portion  71  and the outside edge of the first long-side air outlet  51 . 
     &lt;3-2&gt; Placement Relationship in Neighborhood of Center of Airflow Direction Adjusting Portions  70   
       FIG. 12  is a schematic cross-sectional view, in cross section B-B in  FIG. 11 , in the neighborhood of the first long-side air outlet  51 . The posture of the airflow direction adjusting portion  70  shown in  FIG. 12  is an example of the posture of the flap body  80  in a case where the independent airflow direction control or the interlocking airflow direction control is being performed. 
     As shown in  FIG. 12 , the first long-side air outlet flow path  51   a  extends toward the airflow upstream side from the first long-side air outlet  51 . The inside wall surface of the first long-side air outlet flow path  51   a  in the neighborhood of the first long-side air outlet  51  is configured by the bottom plate  33   b  of the casing body  31   a . In the neighborhood of the lengthwise direction center of the flap body  80 , the inside wall surface of the first long-side air outlet flow path  51   a  has, as shown in  FIG. 12 , a shape curved in such a way that the center of its radius of curvature is positioned on the rotating shaft  90   x  side, and the inside wall surface of the first long-side air outlet flow path  51   a  is formed so as to be positioned further outside closer to the first long-side air outlet  51 . In the neighborhood of the lengthwise direction center of the flap body  80 , the outside wall surface of the first long-side air outlet flow path  51   a  has, as shown in  FIG. 12 , a shape curved in such a way that the center of its radius of curvature is positioned on the opposite side of the rotating shaft  90   x  side so that the distance between the outside wall surface and the inside wall surface is maintained, and the outside wall surface of the first long-side air outlet flow path  51   a  is formed so as to be positioned further outside closer to the first long-side air outlet  51 . The neighborhood of the center of the first long-side air outlet flow path  51   a  is inclined in such a way that an angle of inclination θ 11  of the inside wall surface and the outside wall surface in the section of the first long-side air outlet  51  in the blow-out direction end portion is about 40° with respect to the horizontal direction, so that the blown-out air can be guided more outward. 
     The rotating shaft  90   x  is positioned on the airflow direction upstream side of the first long-side air outlet  51  positioned in the end portion of the first long-side air outlet flow path  51   a . Further, the rotating shaft  90   x  is placed so as to be closer to the outside wall surface side of the first long-side air outlet flow path  51   a  than the inside wall surface side of the first long-side air outlet flow path  51   a.    
     The arm  90  is positioned in a position substantially coinciding with, or on the airflow upstream side of, the first long-side air outlet  51  positioned in the end portion of the first long-side air outlet flow path  51   a  even in the rotational state closest to the first long-side air outlet  51  of the rotational states of the first airflow direction adjusting portion  71 . 
     As shown in  FIG. 12 , the width direction length, in the neighborhood of the center, of the flap body  80  is disposed in such a way that an angle θ 1  formed by a line joining together the rotating shaft  90   x  and one width direction end side of the flap body  80  and a line joining together the rotating shaft  90   x  and the width direction other end side of the flap body  80  is about 135°. 
     When the independent airflow direction control or the interlocking airflow direction control is being performed, the flap body  80  of the airflow direction adjusting portion  70  is swung by the airflow direction adjusting drive units  95  in the range of about +30° and about −30° taking as a reference a state where the angle of inclination of the section, in the neighborhood of the center, of the front surface  80   x  is about 30° (corresponding to  FIG. 12 ). 
     &lt;3-3&gt; Placement Relationship in Neighborhoods of End Portions of Airflow Direction Adjusting Portions  70   
       FIG. 13  is a schematic cross-sectional view, in cross section C-C in  FIG. 11 , in the neighborhood of the first long-side air outlet  51 . 
     In the neighborhoods of the lengthwise direction end portions of the flap body  80 , the inside wall surface of the first long-side air outlet flow path  51   a  has, as shown in  FIG. 13 , a planar shape formed so as to be positioned further outside closer to the first long-side air outlet  51 , so that the shape differs from the curved shape in the neighborhood of the center. Further, in the neighborhoods of the lengthwise direction end portions of the flap body  80 , the outside wall surface of the first long-side air outlet flow path  51   a  is like the inside wall surface and has, as shown in  FIG. 13 , a planar shape formed so as to be positioned further outside closer to the first long-side air outlet  51 , so that the shape differs from the curved shape in the neighborhood of the center. The shapes of the inside wall surface and the outside wall surface of the first long-side air outlet flow path  51   a  are formed in such a way that the shape in the neighborhood of the lengthwise direction center of the flap body  80  and the shape in the neighborhoods of the lengthwise direction end portions of the flap body  80  change gradually in accordance with the lengthwise direction position of the flap body  80 . The neighborhood of the end portion of the first long-side air outlet flow path  51   a  is inclined in such a way that an angle of inclination θ 21  of the inside wall surface and the outside wall surface in the section of the first long-side air outlet  51  in the blow-out direction end portion is about 55° with respect to the horizontal direction, so that the blown-out air can be guided more downward. 
     The width direction length, in the neighborhoods of the end portions, of the flap body  80  is disposed in such a way that, as shown in  FIG. 13 , an angle θ 2  formed by a line joining together the rotating shaft  90   x  and one width direction end side of the flap body  80  and a line joining together the rotating shaft  90   x  and the other width direction end side of the flap body  80  is about 75°. In other words, the width direction length, in the neighborhoods of the end portions, of the flap body  80  is configured so as to be about 40% of the width direction length, in the neighborhood of the center, of the flap body  80 . 
     &lt;4&gt; Placement Relationship Between Long-side Air Outlets  50  and Airflow Direction Adjusting Portions  70  During Shutdown 
     When the controller  7   c  receives from the user an instruction to shut down (a state where the cooling action and the heating action are not performed), the control unit  7  sends a control signal to the airflow direction adjusting drive units  95  to cause all of the airflow direction adjusting portions  70 —that is, all of the first airflow direction adjusting portion  71 , the second airflow direction adjusting portion  72 , the third airflow direction adjusting portion  73 , and the fourth airflow direction adjusting portion  74 —to rotate, whereby the airflow direction adjusting portions  70  are adjusted so that the centers of their front surfaces  80   x  face substantially vertically downward. 
     Because of this, during shutdown, when the indoor unit  4  is seen from below, the insides of the long-side air outlets  50  appear most covered by the airflow direction adjusting portions  70 , so that the sense of unity between the decorative panel  32  and the airflow direction adjusting portions  70  can be improved. Because of this, the design of the indoor unit  4  during shutdown can be improved, and the user can easily know that the indoor unit  4  is in a shutdown state. 
     &lt;5&gt; Placement Relationship Between Long-side Air Outlets  50  and Airflow Direction Adjusting Portions  70  During Individual Air Volume Suppression Control 
       FIG. 14  is a conceptual diagram of the air volume suppression control. 
     When the controller  7   c  receives from the user an instruction to suppress the volume of air blown out from a specific long-side air outlet  50 , the control unit  7  sends a control signal to the airflow direction adjusting drive units  95 , of the airflow direction adjusting drive units  95 , that control the rotational state of the airflow direction adjusting portion  70  disposed in the position corresponding to the specific long-side air outlet  50  instructed by the user. Because of this, the airflow direction adjusting drive units  95  that have received the control signal cause the airflow direction adjusting portion  70  whose rotational state they themselves control to rotate, to thereby adjust the airflow direction adjusting portion  70  to a posture that restricts the volume of air blown out from the long-side air outlet  50  specified by the user. For example, as shown in  FIG. 14 , in a case where the indoor unit  4  is placed near a wall surface W in a room and near a user P 1  and a user P 2 , when the controller  7   c  receives an instruction to suppress the volume of air blown out toward the user P 2 , the control unit  7  performs the individual air volume suppression control to reduce the volume of the airflow F 53  blown out from the third long-side air outlet  53  toward the wall surface W and to also reduce the volume of the airflow F 52  blown out from the second long-side air outlet  52  toward the user P 2 . Because of this, useless provision of conditioned air toward the wall surface W where there is no user can be reduced, and the air volume desired by the user P 2  can be realized. For example, the instruction given by the user P 2  may include a case where the user P 2  wants to reduce the sensation of a draft or a case where the user P 2  feels too cool or too warm due to cooling or heating. 
       FIG. 15  is a cross-sectional view, corresponding to cross section B-B in  FIG. 11 , showing an example of the inclined state of the airflow direction adjusting portion  70  during the individual air volume suppression control. 
     The flap body  80  on which the individual air volume suppression control is performed is adjusted by the airflow direction adjusting drive units  95  in such a way that the front surface  80   x  faces the airflow upstream side of the first long-side air outlet flow path  51   a . Specifically, the flap body  80  is adjusted by the airflow direction adjusting drive units  95  in such a way that an angle of inclination θ 3  (an inside angle) of the section, in the neighborhood of the center, of the front surface  80   x  with respect to a horizontal plane is about 110° (which corresponds to  FIG. 15 ). During the individual air volume suppression control, as for the posture of the flap body  80 , the flap body  80  is rotated by the airflow direction adjusting drive units  95 , but the flap body  80  and the wall surfaces of the first long-side air outlet flow path  51   a  have a placement relationship such that they do not contact each other during the action of the rotation of the flap body  80  from the posture shown in  FIG. 12  where the independent airflow direction control or the interlocking airflow direction control is being performed to the posture shown in  FIG. 15  where the individual air volume suppression control is being performed. Both the width direction one end side and the width direction other end side of the flap body  80  are temporarily positioned on the airflow downstream side of a surface  51   s  of the first long-side air outlet  51  shown in  FIG. 15  in a case where the flap body  80  is being swung by the airflow direction adjusting drive units  95  during the independent airflow direction control or the interlocking airflow direction control. 
     Because of this, the volume of air blown out from the long-side air outlet  50  on which the individual air volume suppression control has been performed can be reduced. The angle of inclination during the individual air volume suppression control is finely adjusted in the range of +5° and −5° from the angle of about 110°. 
     In a state where the individual air volume suppression control has been performed, a gap of about 5 mm to 10 mm is ensured (in the section indicated by S 1  in  FIG. 15 ) between the wall surface of the first long-side air outlet flow path  51   a  on the outer frame decorative panel  38  side and the end portion on the upper side of the flap body  80 , so that a little blow-out air flows through there. 
     Further, in a state where the individual air volume suppression control has been performed, the end portion on the lower side of the flap body  80  (the section indicated by S 2  in  FIG. 15 ) is positioned more on the airflow upstream side in the first long-side air outlet flow path  51   a  than the first long-side air outlet  51 . Because of this, substantially the entire periphery of the flap body  80  can be enveloped by the conditioned air whose temperature has been adjusted inside the indoor unit  4 , and it can be made difficult for the air in the room whose temperature has not been adjusted to touch the flap body  80 . For this reason, even in a state where the volume of air blown out from the long-side air outlet  50  has been reduced by the individual air volume suppression control, it can be made difficult for the room air whose temperature has not been adjusted to reach the flap body  80 , and the formation of dew condensation on the flap body  80  can be suppressed. 
     &lt;6&gt; Characteristics of Present Embodiment 
     (1) 
     In the indoor unit  4  of the air conditioning apparatus  1  of the present embodiment, the flap body  80  positioned in the long-side air outlet  50  specified during the individual air volume suppression control can significantly suppress the volume of air blown out from the specific long-side air outlet  50  as a result of the rotational state of the airflow direction adjusting portion  70  being adjusted by the airflow direction adjusting drive units  95 . Because of this, the volume of air blown out in a specific direction can be suppressed without blocking the specific long-side air outlet  50  using a member separate from the flap body  80  etc. or greatly changing the airflow direction. 
     Moreover, the control unit  7  automatically starts the individual air volume suppression control simply as a result of the user designating and inputting to the controller  7   c  a specific long-side air outlet  50  of the plural long-side air outlets  51  to  54 , so the comfort of a specific user can be improved with a simple action. 
     (2) 
     For example, when blocking the first long-side air outlet  51  in the individual air volume suppression control, in contrast to the above embodiment, as shown in the comparative example of  FIG. 16 , when employing a rotational state to the extent that the surface of the flap body  80  in the neighborhood of the lengthwise direction center of the front surface  80   x  becomes parallel to the surface  51   s  of the first long-side air outlet  51 , it is difficult for the air whose temperature has been adjusted from the inside of the indoor unit  4  to touch the front surface  80   x  side of the flap body  80 , and it is easy for air R 51  whose temperature has not been adjusted on the room side to flow into the front surface  80   x  side of the flap body  80 . On the other hand, it is easy for the air whose temperature has been adjusted from the inside of the indoor unit  4  to touch the back surface  80   y  side of the flap body  80 . For this reason, even if it can be made to appear that the first long-side air outlet  51  is closed, it is easy for a temperature difference to arise between the front surface  80   x  and the back surface  80   y  of the flap body  80 , and it is easy for dew condensation to form on the front surface of the flap body  80 . 
     With respect to this, in the indoor unit  4  of the air conditioning apparatus  1  of the present embodiment, as shown in  FIG. 15 , while the airflow direction adjusting drive units  95  adjust the posture of the flap body  80  in such a way the front surface  80   x  of the flap body  80  during the individual air volume suppression control faces the upstream side of the first long-side air outlet flow path  51   a  etc., the flap body  80  is adjusted by the airflow direction adjusting drive units  95  in such a way that the outside wall surface of the first long-side air outlet flow path  51   a  and the one end of the flap body  80  have a positional relationship in which they do not contact each other (see S 1  in  FIG. 15 ). For this reason, air whose temperature has been adjusted flows on both the front surface  80   x  side and the back surface  80   y  side of the flap body  80 . 
     Further, by putting the rotational state of the flap body  80  during the individual air volume suppression control into a state with the angle of inclination shown in  FIG. 15 , the airflow heading from the first long-side air outlet  51  outside can be effectively suppressed, and differences in the percentages of the volumes of the conditioned air flowing on the front surface  80   x  side and the back surface  80   y  side can be more or less suppressed. 
     Moreover, the rotational state of the flap body  80  during the individual air volume suppression control is adjusted in such a way that, as shown in  FIG. 15 , the projecting front surface  80   x  side of the flap body  80  faces the upstream side of the first long-side air outlet flow path  51   a  and the recessed back surface  80   y  side of the flap body  80  faces the downstream side of the first long-side air outlet flow path  51   a . For this reason, compared to a posture where, as shown in  FIG. 16 , the projecting front surface  80   x  side of the flap body  80  faces the downstream side of the first long-side air outlet flow path  51   a  and the recessed back surface  80   y  side of the flap body  80  faces the upstream side of the first long-side air outlet flow path  51   a , it becomes more difficult for a temperature difference between the front surface  80   x  side and the back surface  80   y  side of the flap body  80  to arise. Further, the extent of turbulence in the traveling direction of the conditioned air can be suppressed. 
     In addition, the airflow direction adjusting drive units  95  adjust the rotational state of the airflow direction adjusting portion  70  in such a way that the flap body  80  during the individual air volume suppression control does not have a section positioned on the airflow direction downstream side of the long-side air outlet  50 . Because of this, it becomes more difficult for the air whose temperature has not been adjusted on the room side to reach the flap body  80 . 
     Additionally, the flap body  80  during the individual air volume suppression control has a posture where the air whose temperature has been adjusted more easily strikes the front surface  80   x  side than the back surface  80   y  side, but because the flocked sheet  80   ya  that suppresses the formation of dew condensation is disposed on the back surface  80   y  side of the flap body  80 , it is difficult for dew condensation to form even if the room air whose temperature has not been adjusted were to more or less flow into the back surface  80   y  side of the flap body  80 . 
     Because of this, the air whose temperature has been adjusted can flow along not only the front surface  80   x  but also the back surface  80   y  with respect to the flap body  80  when performing the individual air volume suppression control. For this reason, the temperature difference between the front surface  80   x  and the back surface  80   y  of the flap body  80  can be kept small, and the formation of dew condensation can be more effectively suppressed. Particularly in a state where the air conditioning apparatus  1  is performing the cooling action, the formation of dew condensation on the flap body  80  can be suppressed. 
     (3) 
     In the indoor unit  4  of the air conditioning apparatus  1  of the present embodiment, as described above, a structure by which the position of the flap body  80  in the airflow direction in the first long-side air outlet flow path  51   a  is caused to move so as to be on the downstream side during the independent airflow direction control or the interlocking airflow direction control and on the upstream side during the individual air volume suppression control is realized as a result of the arms  90  interconnecting the rotating shafts  90   x  and the flap body  80  placed in a position away from the rotating shafts  90   x.    
     In this way, by employing a structure where the flap body  80  is placed away from the rotating shafts  90   x  and where the rotating shafts  90   x  and the flap body  80  are interconnected by the arms  90 , the flap body  80  can be easily moved to a desired position during each control simply by rotating. 
     (4) 
     In the indoor unit  4  of the air conditioning apparatus  1  of the present embodiment, in the long-side air outlet  50  on which the individual air volume suppression control is being performed, the air tends to flow along the surface of the ceiling U because the speed of the passing air drops. 
     With respect to this, in the indoor unit  4  of the air conditioning apparatus  1  of the present embodiment, as shown in  FIG. 15 , while the posture of the flap body  80  is adjusted in such a way that the front surface  80   x  of the flap body  80  during the individual air volume suppression control faces the upstream side of the first long-side air outlet flow path  51   a  etc., the distance between the outside wall surface of the first long-side air outlet flow path  51   a  and the flap body  80  becomes narrower (see S 1  in  FIG. 15 ). Consequently, the volume of air flowing out from the long-side air outlet  50  on which the individual air volume suppression control is being performed and staying in the neighborhood of the ceiling U can be reduced so that ceiling dirtying can be suppressed. 
     (5) 
     In the indoor unit  4  of the air conditioning apparatus  1  of the present embodiment, the flap body  80  during the individual air volume suppression control is in a state where the back surface  80   y  side on which the flocked sheet  80   ya  is disposed faces the room side, and the front surface  80   x  side that has a flat shape cannot be directed toward the room side. However, during the individual air volume suppression control, the flap body  80  is not in the exit of the first long-side air outlet flow path  51   a  etc. but in a slightly deep-set position, so it becomes difficult for the back surface  80   y  of the flap body  80  to be able to be seen, and the placement is such that if is difficult to see the inside of the indoor unit  4 , so the design can be improved. 
     &lt;7&gt; Other Embodiments 
     (A) 
     In the above embodiment, a case of suppressing the volume of air blown out from the long-side air outlet  50  specified when receiving an instruction from the user to perform the individual air volume suppression control was taken as an example and described. 
     However, the present invention is not limited to this and may also, for example, be configured to perform control that not only suppresses the volume of air blown out from the long-side air outlet  50  specified when receiving an instruction from the user to perform the individual air volume suppression control but at the same time also reduces the air volume of the indoor fan  41  so as make it substantially inversely proportional to the number of the long-side air outlets  50  on which the individual air volume suppression control is being performed. 
     Because of this, in a case where the volume of air supplied to a specific user has been reduced, the volume of air supplied to another user can be prevented from unintentionally ending up increased. 
     (B) 
     In the above embodiment, a case where, in the independent airflow direction control, the airflow direction adjusting drive units  95  cause the airflow direction adjusting portions  70  to rotate was taken as an example and described. 
     However, the present invention is not limited to this and may also, for example, be configured to change, in the independent airflow direction control, the upper limit and the lower limit of the swinging angle per each of the airflow direction adjusting portions  70  whose rotation the airflow direction adjusting drive units  95  control in a case where, for example, there is an input via the controller  7   c  from the user or in the case of performing a predetermined operating mode. 
     Because of this, the airflow direction adjusting drive units  95  do not put the airflow direction adjusting portions  70  in a state in which the airflow direction adjusting portions  70  virtually stop the air blown out from the long-side air outlets  50  as a result of the individual air volume suppression control being performed, but the airflow direction adjusting drive units  95  can cause the airflow direction adjusting portions  70  to swing in avoidance of a section where a user who dislikes the sensation of a draft is positioned, and it also becomes possible to maintain the comfort of another user in the area around the user who dislikes the sensation of a draft. 
     (C) 
     In the above embodiment, a case of significantly suppressing the volume of air blown out from the long-side air outlet  50  for which an instruction to perform the individual air volume suppression control has been received was taken as an example and described. 
     However, the present invention is not limited to this; for example, the control unit  7  may, in regard to the posture of the flap body  80  in the long-side air outlet  50  for which an instruction to perform the individual air volume suppression control has been received, perform control that intermittently releases, at appropriate time intervals, the posture in which the flap body  80  suppresses the air volume, such as, for example, using the airflow direction adjusting drive units  95  to put the flap body  80  in a posture in which the flap body  80  suppresses the air volume for a predetermined amount of time and thereafter causing the flap body  80  to perform an ordinary swing operation during another predetermined amount of time. 
     (D) 
     In the above embodiment, a case where the number of the long-side air outlets  50  on which the individual air volume suppression control can be simultaneously performed is determined to be two or less and the control unit  7  performs control was taken as an example and described. 
     However, the present invention is not limited to this; for example, the control unit  7  may also perform control in such a way that the number of the long-side air outlets  50  on which the individual air volume suppression control can be simultaneously performed is just one. 
     Further, in a case where there are more than four air outlets in which flaps that can adjust the airflow direction are placed, the present invention may be configured in such a way that it can simultaneously perform the individual air volume suppression control on up to 50% of those or may be configured in such a way that it can simultaneously perform the individual air volume suppression control on up to 25%) individually. 
     (E) 
     In the above embodiment, the indoor unit  4  that blows out conditioned air in eight directions was taken as an example and described. 
     However, the present invention is not limited to this and may also have a configuration where, for example, in the above embodiment, the short-side air outlets  60  are not disposed and the blow-out directions are only those of the four long-side air outlets  50 . Further, the indoor unit may also be one where there are two air outlets. 
     INDUSTRIAL APPLICABILITY 
     According to the present invention, the volume of air blown out from any air outlet of plural air outlets can be reduced while suppressing dew condensation without using a new part, so the present invention is particularly useful in an indoor unit of air conditioning apparatus.
