Description
- A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever. 37 CFR 1.71(d).
- This invention relates generally to air conditioning systems, and more specifically to the cooling of air conditioning systems to increase efficiencies thereof.
- Prior art air conditioning system cooling mechanisms rely on water/mist being sprayed directly onto the coils and condenser of an outdoor unit of an air conditioning system. The problem is that the water creates scaling, rust, and corrosion over time, thereby creating holes in the coils and condenser resulting in leaks and eventually complete failure of the air conditioning system. Accordingly, the present invention overcomes the disadvantages associated with the prior art, by providing an improved air conditioner cooling system for air cooling the condenser and coils of an air conditioner while the condenser works to cool down the refrigerant being used in the air conditioning system, thereby increasing the efficiency of the air conditioning system and reducing energy consumption.
- In view of the foregoing disadvantages inherent in the known types of air conditioner cooling systems or the like in the prior art, the present invention provides an improved air conditioner cooling system for air cooling the condenser and coils of an air conditioner while the condenser works to cool down the refrigerant being used in the air conditioning system, thereby increasing the efficiency of the air conditioning system and reducing energy consumption. The improved air conditioner cooling system includes a plurality of cooling pads, a water reservoir, a water pump, water pipes carrying water from the water reservoir, through the water pipes and to and upon the cooling pads, and a cover for partially covering the top of the air conditioning housing surrounding the condenser and coils of the air conditioning system. The improved air conditioner cooling system allows air to be drawn through the cooling pads, cooled down by the water upon the cooling pads, and pass through and into the air conditioner housing thereby cooling the condenser and coils thereof, with all the advantages of the prior art and none of the disadvantages.
- There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.

- Turning now descriptively to drawing, referring to
FIGS. 1-4 , the present invention discloses an improved air conditioner cooling system for cooling a condenser and coils of an air conditioning unit, thereby increasing the efficiency thereof. - As shown in
FIGS. 3 and 4 , air conditioning unit 400 includes a housing 410 that forms an interior volume and includes an opening 420 in a top section thereof adapted to allow air to flow into and out of the interior volume via a fan 430 having a motor. The air conditioning unit 400 further include a condenser 440 located within the interior volume of the housing, coils 450 also located within the interior volume of the housing and connected to the condenser, and a fan 430 run by a fan motor, wherein the fan is located adjacent the opening in the top section of the housing and is adapted to force air out of the interior volume of the housing. - As shown in
FIGS. 1-4 , the improved air conditioner cooling system 100 comprises three cooling pads 110, each cooling pad 110 includes a series of fins 112 adapted to allow heat exchanging between air passing therethrough and water passing there over, wherein said three cooling pads 110 are adapted and arranged to surround the air conditioning unit 400 on three side portions thereof, a water pipe 120 including a series of holes 122 along a substantial length thereof, wherein a water pump 124 is adapted to pump water through water pipe 120 and through the series of holes 122 to flow over the series of fins 112 of the three cooling pads 110, a water reservoir 130 shaped and positioned to gather water running off from the three cooling pads 110, and a cover member 160 connected to a top edge of each of the three cooling pads 110, and is adapted to cover a top portion of the air conditioning unit 400 and allow air to pass through a center section thereof. The cooling pads 110 are adapted to be placed in proximity to, but not touching, the housing 410 of the air conditioning unit 400, to thereby form a space 200 there between. - When in use, water enters water supply pipe 126 from an external water supply, usually from within a building structure, and then enters into water reservoir 130. A leveler 188 ensures that the correct water level always exists within water reservoir 130. When the leveler 188 detects a drop in the necessary water level within water reservoir 130 more water is allowed to flow from the external water supply and into the water reservoir 130 until the correct level is achieved once again. From there, the water is pumped via pump 124 through water pipe 120, over the three cooling pads 110, and collected back into water reservoir 130 for use all over again. As such, when in use, air flowing into the air conditioning unit 400 passes through the three cooling pads 110, is cooled by the water passing over the three cooling pads, enters the air conditioning unit 400, and then contacts and cools the condenser and coils of the air conditioning unit, thereby increasing the efficiency of the air conditioning unit.
- Water nozzle 140 is attached to water reservoir 130 and is adapted to allow water from water pipe 126 to enter water reservoir 130 and to continue to water pump 124 and to water pipe 120. Further, the water pump 124 is adapted to turn on and off when the condenser of the air conditioning unit is turned on and off. As such, the improved air conditioner cooling system is only operating when the condenser of the air conditioner unit is operating. Further, in the preferred embodiment, the three cooling pads 110 are connected to one another forming three sides of a rectangular shape, and are adapted such that the improved air conditioner cooling system can be placed around and then removed from most any air conditioning unit. Furthermore, the cover member 160 may be formed having a substantially rectangular shape similar to the rectangular shape formed by the three cooling pads, and include a substantially circular center opening 162 therethrough adapted to allow air to pass therethrough.
- The water reservoir 130 may be formed from three separate water reservoir units 130 interconnected via water hoses 132 therebetween, and adapted such that each of the three separate water reservoir units are attached to a bottom portion of a respective cooling pad and are formed to surround the bottom portion of each respective cooling pad.
- The three cooling pads 110, the water pipe 120, the water reservoir 130, and the cover member 160 may be formed from plastic, copper, or aluminum, though other materials may be used as well.
- Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that any arrangement, which is calculated to achieve the same purpose, may be substituted for the specific embodiment shown. This application is intended to cover any adaptations or variations of the present invention.
- Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention.
