The present invention also relates to a heat source unit of a refrigeration apparatus provided with an airflow-direction adjustment unit.
BACKGROUND ART
Air conditioners and/or water heaters, as well as other refrigeration apparatuses are conventionally provided with an outdoor unit and/or a heat pump unit, or another heat source unit disposed outdoors. An example of such a heat source unit is disclosed in Japanese Laid-open Patent Application No. 2001-108262, wherein an outdoor unit is provided with a casing and/or a heat exchanger, a fan, or the like. In particular, the outdoor unit related to Japanese Laid-open Patent Application No. 2001-108262 has a configuration in which air expelled via the front surface of the casing is expelled from the outdoor unit from a lateral direction in order to prevent an increase in noise generated by the airflow.
SUMMARY
Technical Problem
There are occasionally directions in which air is not intended to be expelled, due to the environment in which the heat source unit is disposed. In response to this situation, the outdoor unit related to Japanese Laid-open Patent Application No. 2001-108262 can be arranged in an environment in which air is not intended to be expelled toward the front surface of the unit since, as noted above, because air is expelled to the exterior only in the lateral direction; however, complications are presented in situating the unit within environments where air is not intended to be expelled in, e.g., the lateral direction.
In view of the above, an object of the present invention is to provide an airflow-direction adjustment unit in which air from the casing of the heat source unit can be blown in a desired direction, and a heat source unit of a refrigeration apparatus provided with an airflow-direction adjustment unit.
Solution to the Problem
An airflow-direction adjustment unit according to a first aspect of the invention adjusts the direction of air expelled from a main body of a heat source unit of a refrigeration apparatus to the exterior, and comprises a mounting member and a closing member. The mounting member is mounted on the heat source unit main body and has at least one expulsion opening for air from the heat source unit main body. The closing member blocks some portion at least one of the expulsion openings.
In accordance with this airflow-direction adjustment unit, the mounting member having at least one expulsion opening is mounted on the main body of the heat source unit, and some portion at least one of the expulsion openings are blocked by the closing member. The air expelled from the heat source unit to the exterior is accordingly expelled from unblocked expulsion openings. Therefore, air can be expelled in a desired direction.
The airflow-direction adjustment unit according to a second aspect of the invention is the airflow-direction adjustment unit according to the first aspect of the invention, wherein the heat source unit main body is of a type for blowing the air to the front surface. The mounting member is a box-shaped member mounted on the front surface of the heat source unit main body. The expulsion openings are provided to two or more surfaces among a front surface, an upper surface, a lower surface, and two side surfaces of the mounting member.
In accordance with this airflow-direction adjustment unit, some portion at least one of the expulsion openings provided to two or more surfaces of the mounting member are suitably blocked by the closing member, whereby the direction of air expelled from the main body of the heat source unit to the front surface can be changed to a desired direction.
The airflow-direction adjustment unit according to a third aspect of the invention is the airflow-direction adjustment unit according to the first or second aspect of the invention, wherein the closing member is at least partially supported by the mounting member. The closing member blocks the expulsion opening by moving in a relative manner with regard to the mounting member.
In accordance with this airflow-direction adjustment unit, the closing member moves relative to the mounting member to suitably block the expulsion opening. Accordingly, there is no requirement to confirm the environmental state around the arrangement position of the heat source unit in advance and form the closing member in accordance with the confirmation result. The expulsion openings can be suitably blocked in a flexible and rapid manner in accordance with the environmental state when the heat source unit is arranged.
A heat source unit of a refrigeration apparatus according to a fourth aspect of the invention comprises an airflow-direction adjustment unit and a heat source unit main body. The airflow-direction adjustment unit is the airflow-direction adjustment unit according to any the first to third aspects of the invention. In the heat source unit main body, the direction of air expelled to the exterior is adjusted by the airflow-direction adjustment unit. A heat exchanger and a fan are accommodated in the heat source unit main body. The heat exchanger exchanges heat with air. The fan delivers the air that has undergone heat exchange in the heat exchanger to the expulsion opening.
In accordance with this heat source unit of a refrigeration apparatus, the air that has undergone heat exchange is expelled from the heat source unit via the expulsion openings that are not blocked by the closing member of the airflow-direction adjustment unit. Therefore, the heat source unit can blow out air heated by, e.g., heat exchange, in a desired direction.
The heat source unit of a refrigeration apparatus according to the fifth aspect of the invention is the heat source unit of a refrigeration apparatus of the fourth aspect of the invention, wherein the heat source unit main body and at least a portion of the mounting member in the airflow-direction adjustment unit are integrally formed.
Advantageous Effects of Invention
In accordance with the airflow-direction adjustment unit of the first aspect, air can be expelled in a desired direction because the air from the heat source unit is expelled from unblocked expulsion openings.
In accordance with the airflow-direction adjustment unit of the second aspect, some portion at least one of the expulsion openings provided in two or more surfaces of the mounting member are suitably blocked by the closing member, whereby the direction of the air expelled from the main body of the heat source unit to the front surface can be changed to a desired direction.
In accordance with the airflow-direction adjustment unit of the third aspect, there is no requirement to confirm the environmental state around the arrangement position of the heat source unit in advance and foam the closing member in accordance with the confirmation result. The expulsion openings can be suitably blocked in a flexible and rapid manner in accordance with the environmental state when the heat source unit is arranged.
In accordance with the heat source unit of a refrigeration apparatus of the fourth and fifth aspects, the heat-exchanged air is expelled to the exterior of the heat source unit via the expulsion openings that are not blocked by the closing member of the airflow-direction adjustment unit. Therefore, the heat source unit can blow out air heated by, e.g., heat exchange, in a desired direction.

DETAILED DESCRIPTION OF EMBODIMENT(S)
The airflow-direction adjustment unit according to an embodiment of the present invention and the heat source unit of a refrigeration apparatus provided with the airflow-direction adjustment unit are described in detail below with reference to the drawings.
(1) Configuration
FIG. 1 is a view of the external appearance of the outdoor unit in which the heat source unit of a refrigeration apparatus of the present embodiment has been used. The outdoor unit 1 of FIG. 1 is connected via a refrigerant tube (not shown) to an indoor unit (not shown) mounted on an indoor wall or the like, and constitutes an air conditioning apparatus (corresponding to the refrigeration apparatus). The air conditioning apparatus can carry out indoor air cooling operation and/or air warming operation, and other operations.
The outdoor unit 1 according to the present embodiment is mainly provided with a casing 2 (corresponding to the heat source unit main unit), an outdoor heat exchanger 3, a compressor 4, an electrical components unit 5, an air-feed section 6, a bell mouth 7, and an airflow-direction adjustment unit 8, as shown in FIGS. 1 to 3.
In the description below, the terms “above,” “below,” “right,” “left,” “perpendicular,” and other expressions indicating direction are used where appropriate, such terms expressing directions in which the outdoor unit 1 is arranged outdoors as shown in FIG. 1, and is in an ordinary state of use.
(Casing)
The casing 2 has a substantially rectangular parallelepiped shape, as shown in FIGS. 1 and 2, and is formed using sheet metal and resin. The interior of the casing 2 is divided into a machine chamber S1 and an air-feed chamber S2 by a partition plate 2a that extends substantially vertically, as shown in FIG. 3. The compressor 4 and the electrical components unit 5 are disposed in the machine chamber 51, and the outdoor heat exchanger 3 and the air-feed section 6 are disposed in the air-feed chamber S2.
An air-feed port 2b and an intake port (not shown) are formed in the casing 2. The air-feed port 2b is formed in the front surface 21 of the casing 2 and has a substantially circular shape, as shown in FIG. 2. Air from the air-feed port 2b is expelled from the interior of the casing 2 to the exterior. The air is eventually expelled to the exterior of the outdoor unit 1, and when the air is expelled to the exterior of the outdoor unit 1, it is blown in the direction adjusted by the airflow-direction adjustment unit 8, described further below. The intake port is formed in the back surface 23 of the casing 2 and in the left side surface 22 of the casing 2 as viewed from above, as shown in FIG. 3.
(Outdoor Heat Exchanger)
The outdoor heat exchanger 3 exchanges heat with air taken into the casing 2 via the intake port. The outdoor heat exchanger 3 is substantially L-shaped and is arranged so as to conform to the left side surface 22 and the back surface 23 of the casing 2. More specifically, the outdoor heat exchanger 3 has a first portion 3a extending along the left side surface 22 and a second portion 3b extending along the back surface 23 of the casing 2. In other words, the first portion 3a extends substantially parallel to the rotating center shaft Y1 of the fan 62 included in the air-feed section 6, and the second portion 3b extends substantially parallel to the direction substantially orthogonal to the rotating center shaft Y1 of the fan 62.
Such an outdoor heat exchanger 3 has a heat transfer tube (not shown) folded back a plurality of times at the two ends in the lengthwise direction, and a fin section (not shown) that includes a plurality of fins through which the heat-transfer tube is inserted. The heat transfer tube is connected to a refrigerant tube (not shown), and refrigerant that flows inside the refrigerant tube (not shown) flows into the heat transfer tube.
(Compressor)
The compressor 4 compresses the refrigerant that flows inside the refrigerant tube (not shown) and is arranged inside the machine chamber S1. More specifically, the compressor 4 is arranged near the partition plate 2a and below the electrical components unit 5 inside the machine chamber S1. The compressor 4 is driven by a compressor motor.
(Electrical Components Unit)
The electrical components unit 5 accommodates a control board on which capacitors and transistors, and a plurality of other electrical components are mounted; and a reactor and the like; and is arranged on the upper side of the compressor 4 in the machine chamber S1. A plurality of harnesses extend from the control board inside the electrical components unit 5. These harnesses transmit drive control signals and the like to the compressor 4 and/or a fan motor 61 in the air-feed section 6; and extend from the electrical components unit 5 to the compressor 4, the fan motor 61, and the like.
(Air-Feed Section)
The air-feed section 6 feeds air that has undergone heat exchange in the outdoor heat exchanger 3 to the airflow-direction adjustment unit 8 via the air-feed port 2b of the casing 2, and is disposed in the air-feed chamber S2. The air-feed section 6 has the fan motor 61 and the fan 62.
The fan motor 61 is the rotational drive source of the fan 62, and is secured to a fan motor base 61a mounted on the back surface 23 of the casing 2. The output shaft of the fan motor 61 is connected to the rotating center shaft of the fan 62. Therefore, when the fan motor 61 rotates based on a drive control signal outputted from the control board of the electrical components unit 5, the fan 62 can rotate because the rotation is transmitted to the rotating center shaft Y1 of the fan 62 via the output shaft of the fan motor 61.
The fan 62 is a propeller fan having a plurality of blades, and is disposed in a position that corresponds to the air-feed port 2b of the casing 2 so that air in the air-feed chamber S2 can be expelled to the exterior. The fan 62 is caused to rotate by the fan motor 61, whereby an airflow can be generated so that air that has undergone heat exchange in the outdoor heat exchanger 3 flows to the front surface 21 side of the casing 2.
(Bell Mouth)
The bell mouth 7 is correspondingly provided with respect to the fan 62 and the air-feed port 2b of the casing 2. The bell mouth 7 is secured to the casing 2, and an aperture 7a for directing the flow of air formed by the fan 62 to the exterior of the casing 2 (i.e., the airflow-direction adjustment unit 8) is formed in the bell mouth 7. The aperture 7a has a substantially circular shape and is substantially the same size as the air-feed port 2b of the casing 2 (FIG. 2).
(Airflow-Direction Adjustment Unit)
The airflow-direction adjustment unit 8 adjusts the direction of air expelled from the interior of the casing 2 to the exterior of the casing 2, and is mounted on the casing 2 so as to cover the front surface 21 of the casing 2. The work for mounting the casing 2 of the airflow-direction adjustment unit 8 may be carried out by, e.g., a technician when the outdoor unit 1 is actually installed outdoors, or may be carried out by a factory worker when the outdoor unit 1 is manufactured (i.e., before the outdoor unit 1 is shipped). The airflow-direction adjustment unit 8 comprises a mounting member 81 and a closing member 87.
The mounting member 81 is box-shaped and is mounted on the front surface 21 of the casing 2. More specifically, the mounting member 81 has a front surface 82, an upper surface 83, a lower surface 84, a left side surface 85, and a right side surface 86, as shown in FIGS. 1 and 2, and is formed using, e.g., sheet metal. A plurality of expulsion openings 82a to 82h, 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h are formed in the surfaces 82 to 86 of the mounting member 81 (FIG. 4). More specifically, eight expulsion openings 82a to 82h, 85a to 85h, 86a to 86h are formed in the front surface 82, the left side surface 85, and the right side surface 86, respectively, of the mounting member 81. Two expulsion openings 83a and 83b, 84a and 84b are formed in the upper surface 83 and the lower surface 84, respectively, of the mounting member 81. The expulsion openings 82a to 82h, 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h are apertures via which air is expelled from the casing 2 to the exterior of the outdoor unit 1, and each expulsion opening has a rectangular shape in the present embodiment.
The closing member 87 blocks some portion at least one of the expulsion openings 82a to 82h, 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h in the mounting member 81, and is arranged between the casing 2 and the mounting member 81. In the present embodiment, the case in which the closing member 87 blocks the lower portion of the mounting member 81 is used as an example, as shown in FIG. 1. More specifically, the closing member 87 blocks the expulsion openings 82e to 82h positioned in the lower portion (i.e., the lower half) of the front surface 82 of the mounting member 81, the expulsion openings 84a, 84b of the lower surface 84, and the expulsion openings 85e to 85h, 86e to 86h positioned in the lower portion (i.e., the lower half) of each of the left side surface 85 and the right side surface 86, as shown in FIG. 4. Accordingly, the closing member 87 has a shape formed by the front surface, the lower surface, and the two side surfaces (FIG. 2). In particular, the front surface and the two side surfaces of the closing member 87 have substantially the same size as the horizontal half of the front surface 82 and the two side surfaces 85, 86, respectively, of the mounting member 81. The lower surface of the closing member 87 has substantially the same size as the lower surface 84 of the mounting member 81. The closing member 87 is arranged so that the front surface and the two side surfaces of the closing member 87 are in contact with the lower half of the front surface 82 and the two side surfaces 85, 86, respectively, of the mounting member 81, and the lower surface of the closing member 87 is in contact with the lower surface 84 of the mounting member 81 (FIG. 2). In this case, the closing member 87 is formed from a material, e.g., sheet metal, that does not readily transmit air.
When an airflow-direction adjustment unit 8 of such description is mounted on the front surface 21 of the casing 2, the air-feed port 2b of the front surface 21 of the casing 2 is covered by the airflow-direction adjustment unit 8. Among the expulsion openings 82a to 82h, 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h in the mounting member 81 of the airflow-direction adjustment unit 8, the expulsion openings 82e to 82h, 84a and 84b, 85e to 85h, 86e to 86h positioned in the lower half of the mounting member 81 are blocked by the closing member 87, but the expulsion openings 82a to 82d, 83a and 83b, 85a to 85d, 86a to 86d positioned in the upper half of the mounting member 81 are not blocked. Accordingly, the air expelled from the interior of the casing 2 via the air-feed port 2b is expelled from the unblocked expulsion openings 82a to 82d, 83a and 83b, 85a to 85d, 86a to 86d to the exterior of the outdoor unit 1, as shown by the arrow in FIG. 4. Therefore, the outdoor unit 1 according to the present embodiment has a front-blow-type casing 2, and air is not blown below the outdoor unit 1 and is mainly blown above the outdoor unit 1 because of the airflow-direction adjustment unit 8.
(2) Effects
(A)
The airflow-direction adjustment unit 8 according to the present embodiment is provided with the mounting member 81 and the closing member 87, and adjusts the direction of air expelled from the casing 2 of the outdoor unit 1 to the exterior. The mounting member 81 is mounted on the casing 2 and has a plurality of expulsion openings 82a to 82h, 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h. The closing member 87 blocks some portion at least one of the expulsion openings 82a to 82h, 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h (specifically, the expulsion openings 82e to 82h, 84a and 84b, 85e to 85h, 86e to 86h). The air expelled from the outdoor unit 1 to the exterior is thereby expelled from the unblocked expulsion openings 82a to 82d, 83a and 83b, 85a to 85d, 86a to 86d. 
(B)
The airflow-direction adjustment unit 8 according to the present embodiment is mounted on the front surface of the front-blow-type casing 2. In particular, the expulsion openings 82a to 82h, 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h in the mounting member 81 of the airflow-direction adjustment unit 8 are provided to the front surface 82, the upper surface 83, the lower surface 84, and the two side surfaces 85, 86, respectively, of the mounting member 81. Therefore, in accordance with this airflow-direction adjustment unit 8, the direction of air expelled to the front surface 21 of the casing 2 of the outdoor unit 1 can be changed to a desired direction by suitably blocking the expulsion openings 82a to 82h, 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h provided to a plurality of surfaces of the mounting member 81.
(C)
The outdoor unit 1 is provided with a casing 2 in which an outdoor heat exchanger 3 and a fan 62 are accommodated. In accordance with this outdoor unit 1, air that has undergone heat exchange in the outdoor heat exchanger 3 is expelled from the outdoor unit 1 via the expulsion openings 82a to 82d, 83a and 83b, 85a to 85d, 86a to 86d that are not blocked by the closing member 87 of the airflow-direction adjustment unit 8.
Other Embodiments
(a)
In the embodiment described above, the case in which the expulsion openings 82e to 82h, 84a and 84b, 85e to 85h, 86e to 86h positioned in the lower half of the mounting member 81 are blocked is used as an example. However, the expulsion openings blocked by the closing member 87 are not limited thereto. In other words, in the airflow-direction adjustment unit 8, a portion of the expulsion openings 82a to 82h, 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h of the mounting member 81 can be blocked by the closing member 87 in accordance with the environment in which the outdoor unit 1 is disposed. Therefore, the air inside the casing 2 can be expelled in a desired direction. Other examples of the embodiment described above are provided in (a-1) to (a-3) below.
(a-1) Blocking of all Expulsion Openings in the Front Surface of the Mounting Member
FIG. 5 shows the outdoor unit 1 for the case in which all of the expulsion openings 82a to 82h in the front surface 82 of the mounting member 81 have been blocked by the closing member 87. According to this outdoor unit 1, air from the casing 2 is expelled through the unblocked expulsion openings 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h of the upper surface 83, the lower surface 84, and the two side surfaces 85, 86 of the mounting member 81, as indicated by the arrow in FIG. 5.
(a-2) Blocking of all Expulsion Openings in the Two Side Surfaces and the Lower Surface of the Mounting Member
FIG. 6 shows the outdoor unit 1 for the case in which all of the expulsion openings 84a and 84b, 85a to 85h, 86a to 86h in the lower surface 84 and the two side surfaces 85, 86 of the mounting member 81 have been blocked by the closing member 87. According to this outdoor unit 1, air from the casing 2 is expelled from the unblocked expulsion openings 82a to 82h, 83a and 83b of the front surface 82 and the upper surface 83 of the mounting member 81, as indicated by the arrow in FIG. 6.
(a-3) Blocking of Expulsion Openings Positioned in the Upper Half of the Mounting Member
FIG. 7 shows the outdoor unit 1 for the case in which expulsion openings 82a to 82d, 85a to 85d, 86a to 86d in the upper half of the front surface 82 and the two side surfaces 85, 86 of the mounting member 81, and the expulsion openings 83a and 83b of the upper surface 83 are blocked by the closing member 87. In accordance with this outdoor unit 1, air from the casing 2 is expelled through the unblocked expulsion openings of the mounting member 81 (i.e., the expulsion openings 82e to 82h, 85e to 85h, 86e to 86h positioned in the lower half of the front surface 82 and the two side surfaces 85, 86; and the expulsion openings 84a and 84b of the lower surface 84) to the exterior of the outdoor unit 1, as indicated by the arrow in FIG. 7.
(b)
Described in the embodiment above is an example of the case in which the expulsion openings 82a to 82h, 83a and 83b, 84a and 84b, 85a to 85h, 86a to 86h are formed in all the surfaces of the mounting member 81. However, the expulsion openings may be formed in at least two surfaces of the mounting member rather than being formed in all the surfaces of the mounting member. Other examples include the case in which the expulsion openings are formed only in the front surface and the upper surface of the mounting member, and/or the case in which the expulsion openings are formed only in the two side surfaces of the mounting member. In these cases as well, the expulsion openings are suitably blocked by the closing member, whereby air inside the casing of the outdoor unit is expelled in a desired direction.
(c)
Described in the embodiment above is an example of the case in which a plurality of expulsion openings are provided in each of the surfaces of the mounting member 81 (e.g., eight expulsion openings 82a to 82h are provided in the front surface 82 of the mounting member 81). However, by way of example, individual expulsion openings 82a′ to 86a′ may be provided in each of the surfaces 82 to 86 of the mounting member, as shown in FIG. 8. In this case, a closing member 87′ suitably blocks a portion of the expulsion openings 82a′ to 86a′, thereby achieving the same effect as that of the embodiment described above.
(d)
Described in the embodiment above is an example of the case in which the airflow-direction adjustment unit 8 and the casing 2 are separate, as shown in FIG. 2, for example. However, the airflow-direction adjustment unit according to the present invention may be at least partially formed integrally with respect to the casing of the outdoor unit. Specifically, a case in which the upper surface and/or the lower surface in the mounting member of the airflow-direction adjustment unit is integrally formed with the casing will be described.

The airflow-direction adjustment unit 308 according to FIG. 11 has a closing member 387 in place of the closing member 87 of the airflow-direction adjustment unit 8 according to the first embodiment. The airflow-direction adjustment unit 308 comprises the same mounting member 81 as the first embodiment. The closing member 387 comprises a plurality of closing plates 388 provided in correspondence with the expulsion openings 82a to 82d, . . . , respectively, and a connecting part 389 that connects the closing plates 388. The closing plates 388 are supported by a rail or the like (not shown) in the vicinity of the expulsion openings 82a to 82d, . . . of the mounting member 81 and can slide to open and close the expulsion openings 82a to 82d, . . . from inside the mounting member 81. The connecting part 389 adjusts the open/close state of the expulsion openings 82a to 82d that is brought about by the closing plates 388. For example, the connecting part 389 is pulled downward (in the direction of the arrow B in FIG. 11(a)) when the closing plates 388 have the expulsion openings 82a to 82d, . . . open, as shown in FIG. 11(a), whereby the closing plates 388 can be set in a state in which each of the expulsion openings 82a to 82d, . . . are closed (blocked) (FIG. 11(b)). In FIG. 11, the closing member 387 in the front surface 82 of the mounting member 81 is shown as an example.
As described above, with the airflow-direction adjustment units 208, 308 according to FIGS. 10 and 11, at least some of the closing members 287, 387 are supported by the mounting member 81, and the closing members 287, 387 block the expulsion openings 82a to 82d, . . . by moving in a relative fashion with respect to the mounting member 81. Such a structure makes it possible to respond promptly to customer requirements even at the time the outdoor unit is being installed, without the need to form the closing member 87 or decide whether the closing member 87 is necessary after the installation position of the outdoor unit 1 has actually been confirmed as in the first embodiment. It is also possible to respond rapidly and flexibly in cases where the environmental state around the installation position of the outdoor unit has changed.
