Description:
FIELD OF THE INVENTION 
   The invention relates generally to an evaporative air cooling method and, more specifically, to an array of two or more evaporative coolers for enhanced cooling especially useful in the Southwest area of the United States. 
   BACKGROUND OF THE INVENTION 
   Most buildings or homes are equipped with at least one type of cooling device. Homes in the Southwest of the United States usually have either at least one evaporative cooler or air conditioner. And traditionally, the user is able to adjust the power or coolant output of the cooling device in order to achieve the desired room temperature inside the building or home. 
   Air conditioners were designed for use in areas of high humidity, however, they do not work cost effectively in areas of low humidity such as in the Southwest of the United States. Also, air conditioners placed on a roof of a building or dwelling lose about 25% of their efficiency because of exposure to the sun besides being very difficult to maintain because of the roof mounting. As a result, air cooling devices are preferably not mounted on roofs. 
   Applicant has discovered that evaporative coolers properly used and properly arranged will provide better cooling for buildings or homes in areas where there is low humidity despite high temperatures (over 100 degrees Fahrenheit). Previously, air conditioners rather than evaporative coolers were the cooling devices that people resorted to for cooling the interior of homes or buildings when the outside temperature exceeded 100 degrees Fahrenheit, even in areas of low humidity such as in the Southwestern part of the United States. 
   An evaporative cooler basically comprises a large fan and water-moistened pads. The outside air is cooled as it passes through the moist pads and is then blown into the building or home providing moist cooled air. 
   In very hot weather (over 100 degrees Fahrenheit), a user is often tempted to turn the evaporative cooling device onto its highest blower setting. Turning an evaporative cooler onto its highest blower setting, however, will not cause the interior room to cool any faster. Instead, by placing the evaporative cooler onto its highest blower setting, the outside air has less time to be cooled before it is blown into the building or home. The result is that the evaporative cooler blows warmer air at a faster rate into the building or home. Furthermore, prior to this invention, evaporative coolers were believed to be ineffective to cool interior portions of a building or home in very hot weather even in areas of low humidity. 
   Therefore a need existed for a method of better operating and placing evaporative coolers in such a way as to create an optimal cooling effect for interior portions of a building or home that would be especially effective in areas of low humidity even if the temperature exceeds 100 degrees Fahrenheit. 
   In order for the vent of the cooling device to reach, for example, the inside of a home, Applicant discovered that it is necessary for the vent to penetrate the wall on which the cooling device is mounted for more efficient and enhanced cooling. Specifically, Applicant discovered that providing an array of evaporative coolers, operated in the manner disclosed herein, that are wall mounted with wall penetrating vents provides cooled air that can more efficiently cool the interior of a building or home. 
   Building codes often prohibit the use of window mounted cooling devices, therefore it is preferable in the Southwest to penetrate and reinforce or provide a brace for the wall rather than mount a cooling unit on a roof in the extreme temperature and sunlight prevalent in the Southwest which destroys the efficiency of a roof mounted cooling device. 
   The frame of a building or home is commonly made up of 2×4 wooden studs spaced approximately sixteen inches apart. In order for the vent to penetrate the wall, at least one or often two of these 2×4s need to be cut. Cutting through these 2×4s is necessary to create the vent, but is structurally undesired because it compromises the structural integrity of the wall of the building or home. 
   Therefore a need also existed for an apparatus for supporting and arranging cooling devices along at least one outer wall of a building or home that bridges the gap in the cut 2×4s while sustaining the weight of the evaporative cooler or the air conditioner placed upon it thereby providing, in effect, a wall brace. 
   SUMMARY OF THE INVENTION 
   An object of the present invention is to provide an improved cooling method. 
   Another object of the present invention is to provide an improved cooling method which comprises placing an array of evaporative coolers in such a way and operated in such a manner as to create an optimal cooling effect. 
   It is another object of this invention to provide an improved cooling method which comprises providing an array of evaporative coolers with each evaporative cooler mounted on a wall of a building or home and having a vent penetrating the wall for efficient and enhanced cooling. 
   Another object of the present invention is to provide an apparatus for supporting and arranging cooling devices along the outer wall of a building or home that bridges the gap in each cut 2×4 while sustaining the weight of the evaporative cooler or the air conditioner placed upon it thereby providing a wall brace.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIGS. 1-3  refer to the preferred embodiment of the invention. They show a support apparatus  110  for supporting and arranging, for example, evaporative cooling devices  1  along the outer wall  2  (see  FIG. 4 ) of a home. The apparatus  110  comprises a main support frame  120  for bridging each gap  3  caused by cutting through at least one or two 2×4s  4  of a frame of a home  7  (see  FIG. 4 ) in order to accommodate a vent  16  (see  FIG. 2 ) of the cooling device  1 . These cut 2×4s  4  each have a top severed end  5  and a bottom severed end  6 . The main support frame  120  has a substantially rectangular configuration  121  (see  FIG. 2 ) and a middle rung  128  traversing widthwise across the rectangular configuration  121 . The apparatus  120  also has a base  130  extending horizontally from the middle rung  128  of the main support frame  120 . Similarly, the base  130  has a substantially rectangular configuration  131  and a middle rung  138  traversing widthwise across the rectangular configuration  131 . The apparatus  110  also has at least two support rungs  140  extending downwardly at an angle from the rectangular configuration  131  of the base  130  into contact with the rectangular configuration  121  of the main support frame  120  for stabilizing and supporting the base  130 . 
   The rectangular configuration  121  of the main support frame  120  further comprises a short top edge  122 , a short bottom edge  123 , and two long side edges  124  (see FIG.  3 ), which together create four corners  125 . The rectangular configuration  131  of the base  130  further comprises a long front edge  132 , a long back edge  133 , and two short side edges  134  (see FIG.  1 ), creating four corners  135 . The base  130  further comprises four corner supports  136  coupled to the corresponding four corners  135  of the rectangular configuration  134  for providing flat surfaces  137  onto which the cooling device  1  may be set. 
   The short top edge  122  of the main support frame  120  preferably has at least two holes  126  for screwing (by means of long sturdy screws shown in  FIG. 2 ) the main support frame  120  onto the two top severed ends  5  of the two cut 2×4s  4 . The short bottom edge  123  of the main support frame  120  preferably has at least two holes  127  for screwing (by means of long sturdy screws shown in  FIG. 2 ) the main support frame  120  onto the two bottom severed ends  6  of the cut 2×4s  4 . Preferably, two additional screw holes  126 R and  126 L are respectively provided (two for each side) on the two long side edges  124  to permit screws to be inserted therein to attach to the wall behind the two long side edges  124  to provide increased support for the support apparatus  110  and any cooling device  1  to be supported by the support apparatus  110 . And the support rungs  140  each abut one of the short side edges  134  of the base  130  and the short bottom edge  123  of the main support frame  120 . 
   Statement of Operation 
     FIGS. 4-6  show a method for providing the apparatus  110  for supporting and arranging cooling devices  1  along the outer wall  2  of a home by positioning at least two of the apparatus  110  (a third apparatus is shown in phantom lines and is used, if needed) along the outer wall  2  while spacing them optimally about three to seven feet from each other and positioning at least two evaporative coolers  8  respectively on the two corresponding apparatus  110 , and setting the evaporative coolers  8  (one at a time) on a low setting  11  (see FIG.  6 ), so as to bring about an optimal cooling effect for the interior portion of the home. Preferably, first one evaporative cooler  8  is set in the low fan position  11  and then when the interior of the building or home gets too hot (about 80 degrees Fahrenheit), another evaporative cooler  8  is turned on and set at the low fan position  11 . By using the evaporative coolers  8  in this manner, it has been discovered that the interior portion of a building or home may be optimally cooled by evaporative coolers even if the outside temperature is over 100 degrees Fahrenheit. 
   As shown in  FIG. 6 , the evaporative coolers  8  each have a fan switch  9  to select a fan speed level (between low and high) for each evaporative cooler  8 . As described above, a user will turn the controls of at least two (one at a time) evaporative coolers  8  onto the low fan setting  11  to create a preferred cooled interior room temperature. If needed, the user will subsequently turn on the control of (one or more) additional evaporative coolers  12  (see FIG.  4  and  FIG. 5 ) onto a low setting  11  as well. Although the evaporative coolers  8 , 12  are each on a low setting  11 , they will work synergistically with the optimal spacing described above to create an optimal cooling effect inside the home. 
   Applicant&#39;s wall mounted array of evaporative coolers (using two evaporative coolers) for Applicant&#39;s 2300 square foot home only cost Applicant $1.20 per day in electricity usage during the approximately 6 cooler months in the Las Vegas, Nev. area which is about $36 per month versus an electricity usage cost of $1.77 per day during the approximately 6 hotter months which is about $57 per month (or only an increase of about 57 cents per day). Contrasted with the use of air conditioners versus Applicant&#39;s array of evaporative coolers, Applicant has achieved much greater savings in electricity costs. Additionally, Applicant&#39;s array of evaporative coolers which are operated in the manner disclosed herein and that are wall mounted with wall penetrating vents provides healthier (external) cooled filtered air that is humidified (versus dry recycled internal air from air conditioners) for an electricity cost of about one sixth the electricity cost of air conditioners thereby reducing the amount of oil, coal, etc. needed for electricity generation. Also, the costs of purchasing evaporative coolers are much less than the costs of purchasing air conditioners. 
   While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
