Description

BACKGROUND OF THE INVENTION

[0001] On hot days, conventional residential or commercial air-conditioning units are frequently overburdened by the task of adequately cooling a home or other building. Often times the cooling system will remain on for long periods of times while the unit tries to maintain a set temperature. Worse yet, the air-conditioning system will operate continuously; even worse, household or building temperature will slowly rise while the air-conditioning unit operates at its maximum cooling capability using large amounts of costly electrical energy.

[0002] When operating in these conditions, the air-conditioning unit is under excessive stress due to internal temperatures and pressures that are at or above maximum design limits which will shorten the life of major components such as the compressor. So in addition to high operating costs, one must deal with increased maintenance costs and the cost of more frequent replacement of major components due to premature wear.

[0003] This invention is a device that will aid the air-conditioning unit on days when the electrical and mechanical demands on the system are excessive and even on days when weather conditions are not so extreme. The inventive system will increase the efficiency of the entire system at any time when it is appropriate to operate an air-conditioning unit with the purpose of cooling a volume of air.

[0004] The system can be constructed in different configurations that will make its application possible with most residential air conditioners. The system has application with larger industrial units as well.

[0005] The invention includes piping network with misting devices configured to envelop a residential or commercial air conditioning unit, thereby cooling air inhaled into the unit.

[0006] It is a well-known thermodynamic phenomenon that the evaporative process of any substance will extract heat from the surrounding air. When water under pressure is released into air as a mist it will more freely evaporate and draw significant quantities of heat from the surrounding environment. This change in thermodynamic state from liquid to vapor cools the surrounding air. Sufficient pressure exists in a public water supply to create a mist or fog when the pressurized water is released through a misting device.

[0007] Through the process of evaporative cooling, the mist cools the ambient air surrounding the air conditioner housing unit. Additional evaporation occurs with the aid of the condensing unit's fan. The result is a system that runs with higher efficiency saving operating costs and maintenance costs.

[0008] When cooler air blows across a heat exchanger, the result is lower internal temperatures and pressures in all parts of the air conditioning system. The are several beneficial consequences of this. First, the compressor will not work as hard to pump the coolant substance (in most cases Freon) through the a closed air-conditioning system, thereby reducing the electrical demand and reducing the current required to run the compressor. Whenever the compressor is in operation, the supplied electrical power will be less.

[0009] Second, the temperature of the supply air flowing through a home or commercial building duct system will be measurably lower compared to an air conditioner unit operating without the misting network. The reduced temperature of air flowing through the duct work will cause the air in the building to be cooled more rapidly. The temperature set on a temperature controlling device such as a thermostat can be reached more quickly and efficiently with the effect that the unit will turn off sooner than if the heat exchange unit (such as an air conditioning compressor) were not being cooled by the evaporating water mist.

[0010] Over all, this invention will allow an air-conditioning system to operate at higher efficiency due to the compound beneficial effects of less compressor on time, and when the compressor is in operation, it will use less energy which can result in significant energy savings. Expected lower maintenance costs are an added dividend.

SUMMARY OF THE INVENTION

[0011] The invention is a system for cooling the intake air for an air conditioner housing unit. The system includes a plurality of conduits connected to a fluid source. At least one nozzle is positioned adjacent a terminal end of each conduit. These nozzles are configured to expel vapor, preferably water vapor, substantially around an entire perimeter of the housing. In a preferred embodiment, the plurality of conduits form a network that engages the housing.

[0012] Optionally, the system may include a valve in communication with the fluid source; this valve may be configured to selectively allow fluid to enter the network of conduits. Additionally, an electronic switch may be used in cooperation with the valve.

[0013] The system may include a sensor in communication with the compressor to sense when the housing inhales air from the surrounding area. Preferably, this sensor may be in communication with the valve, and configured to open the valve when the housing actively inhales air from the surrounding area. Moreover, the sensor may act to close the valve when the compressor is inactive.

[0014] In another preferred embodiment, the sensor is in electric communication with a thermostat and thermometer within the interior of a residence. In this embodiment, a resident may selectively set desired temperature parameters for the interior of the residence, and the sensor may then activate the system when the temperature exceeds these parameters. The system may also include a manifold containing the network, and this manifold may be configured to engage the unit housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] FIG. 1 shows a first embodiment of the system 10 for cooling intake air inhaled into an air conditioning unit housing 12. The system 10 includes a plurality of conduits 24 linked to form a network that generally surround a housing 12. An inlet 22 supplies fluid, preferably water, to the conduits 24. In FIG. 1, each conduit 24 emanates from a central junction 26. A valve 23 or electronic switch 25 may be positioned in communication with the inlet 22; in a preferred embodiment, the switch and valve are positioned in the central junction 26. Generally, the valve 23 and the switch 25 function together as a single electronic shutoff valve, having a solenoid and a valve. Generally, the solenoid will be activated by a 24 Volt signal that appears at a contact point within the condensing housing unit 12.

[0022] As shown in FIG. 1, the housing unit 12 has a top 14 and sides 16, 18. Each of the top 14 and sides 16,18 is equipped with vents 20 to allow air to be inhaled into the housing unit 12. The network of conduits 24 is shown to actually engage the housing unit 12 by sitting atop it. Alternatively, the conduits 24 may be encased within a manifold that is formed to engage the compressor.

[0023] The housing unit 12, as shown in FIG. 1, bears a generally polygonal cross-section at planes parallel to the ground. Of course, it is well-known that compressors are manufactured with varying configurations, such as cylindrical or other polygonal shapes. The system 10 herein disclosed is adaptable to fit varying shapes and sizes of housing units 12.

[0024] Still referring to FIG. 1, each conduit 24 has a first portion 27 that extends from the central junction 26. The first portion 27 terminates at a bend 29, and a terminal portion 28 of the conduit 24 extends from the bend 29. In the embodiment shown in FIG. 1, the bend 29 includes a pair of elbows 30 and a short length of pipe therebetween.

[0025] Still referring to FIG. 1, the terminal portion 28 should be long enough so that it extends over the vent 20 that is respectively positioned on the sides 16, 18 of the housing unit 12. This configuration allows vapor to be expelled from nozzles 32 positioned on each terminal portion 28. The nozzles 32 may point directly at the vents 20; however, they may also be pointed, as shown, at angles displaced from one another along the longitudinal axis of the terminal portion 28.

[0026] A valve 23 is positioned adjacent the fluid inlet 22 in order to selectively enable fluid to pass into the conduits 24 by entering the junction 26. In this embodiment, the valve 23 is in communication with a switch 25. Preferably, the switch 25 is in electric communication with the fan or compressor within housing unit 12. Specifically, when either of these devices (i.e., the fan or compressor) within the housing unit 12 causes air to be inhaled into the housing unit 12 through its vents 20, the switch 25 opens the valve 23. Conversely, when the housing unit 12 is inactive, the switch 25 maintains the valve 23 in a closed position. This valve 23 and switch 25 combination cooperate to conserve fluid.

[0027] FIG. 2 shows another embodiment of the system 10. In order to establish continuity and to facilitate understanding, analogous parts are given identical reference numbers, even if the structure varies. In many ways, the embodiment shown in FIG. 2 is the same as the embodiment depicted in the prior figure. However, note the difference in structure of the conduits 24. Each conduit 24 has an initial section 27 connected to the junction 26 at one end, and an elbow 30 at the other. The elbow 30 connects the initial section 27 to the terminal section 28.

[0028] FIG. 3 shows another embodiment of the system 10. In order to establish continuity and to facilitate understanding, analogous parts are given identical reference numbers, even if the structure varies. The system 10 includes a network of conduits 24 connected to a fluid source (not shown in FIG. 3, but viewable in FIG. 1). A valve 23 is positioned upstream of the junction 26, and a switch 25 is in communication with the valve 23. The switch 25 may be in electric communication with either the fan or compressor within housing unit 12, or may be in electric communication with a thermostat within the building or home. When the housing unit 12 is operative, the switch 25 opens the valve 23, thereby allowing fluid into the conduits 24. Conversely, when the unit is inoperative, the switch 25 maintains the valve 23 in the closed position.

[0029] FIG. 3 shows an alternative design for the terminal section 28. Note that a T-configuration 36 is positioned adjacent a terminal end of the terminal section 28. In this embodiment, nozzles 32 are positioned along the T configuration, and pointed in the general direction of the vents 20 of the housing unit 12. Of course, additional nozzles may be attached to the general vertical portion of the terminal section 28, as well as on the T-portion.

[0030] FIG. 4 shows an another embodiment of the system 10. In order to establish continuity and to facilitate understanding, analogous parts are given identical reference numbers, even if the structure varies.

[0031] As shown in FIG. 4, the inlet 22 supplies fluid, preferably water, to a central junction 26. The inlet 22 may be a common garden hose supplying water to the conduits 24. As shown, the inlet 22 includes a pipe 29 leading to the junction 26. In the embodiment shown in FIG. 3, the conduits 24 form a network that encircles the housing unit 12. While the conduits 24 are shown to be a circular configuration, other configurations are possible, of course. Nozzles 32 are positioned at various locations along the conduits 24 so that faces 16,18 of the housing unit 12 are sprayed with vapor or mist.

[0032] In the embodiment shown in FIG. 4, the pipe 29 also serves as a support that holds the conduits in a position above the ground. Alternatively, stands may be positioned to hold the conduits 24 in a position that would enable the nozzles 32 to expel vapor toward respective vents 20 on the sides 16,18 of the housing unit 12. In another embodiment, braces may be placed or mounted on the sides of the housing unit 12 to provide support for the conduits 24.

[0033] FIG. 5 shows a close-up view of a conduit 24. The first portion 27 of conduit 24 leads to an elbow 30. As shown in FIG. 5, the conduit may be of a well-known, PCV piping; alternatively, any of the parts may be specially made or unitary. The elbow 30 extends between the first portion 27 and the terminal portion 28. At least one nozzle 32 is positioned near a terminal end of the terminal portion 28 of the conduit 24.

[0034] Although the present invention has been described and illustrated in detail, it is to be clearly understood that the same is by way of illustration and example only, and is not to be taken by way of limitation. The spirit and scope of the present invention are to be limited only by the terms of the appended claims.
