Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a system for increasing the efficiency of outdoor air conditioning units and, more particularly, to a system for shading the air conditioning units from direct sunlight.




2. Description of Related Art




Outdoor air conditioning units may typically include a compressor, a condenser, various piping and valves, and a fan, all contained within a housing. The purpose of the air conditioning unit is to transfer the heat from a building or structure to refrigerant in the air conditioning system piping, and then reject this heat to the ambient environment outside of the building or structure.




Many air conditioning units, most notably those used for residential cooling, may be located outdoors, adjacent to, or nearby, the residence. As a result, the air conditioning unit may be exposed to direct sunlight. This exposure can increase the temperature of the air conditioning unit and its internal components. This can reduce the heat transfer rate from the air conditioning unit, and significantly impact the air conditioning unit's efficiency.




Various devices and methods have been proposed in the past to shade air conditioning units from direct sunlight. However, these devices and methods suffer certain drawbacks. For example, some devices are not readily useful with operating air conditioning units, since air flow through the devices may be restricted. Some devices are not readily attachable to, and/or detachable from, the air conditioning unit. Other devices are not readily adjustable once the screens are installed, which means that the positioning of the devices may not be readily changed to adapt to sun angle variations, and/or to optimize airflow around the devices and into the air conditioning unit. Still other units use latches that frictionally engage the concrete slab on which the air conditioning unit is installed, which may not be as reliable as attaching the screen(s) directly to the air conditioning unit.




Hence there is a need for a system of shading air conditioning units that addresses one or more of the above-noted drawbacks. Namely, a system that screens the unit but does not restrict air flow to or from the unit, and/or that is readily adjustable once it is attached, and/or is readily attached to the unit. The present invention addresses one or more of these needs.




SUMMARY OF THE INVENTION




The present invention provides a system for shading air conditioning units that is easy to install, does not significantly restrict air flow, is adjustable, and attached directly to the air conditioning unit.




In one embodiment of the present invention, and by way of example only, a system for shading an air conditioning unit from sunlight includes at least one frame, at least one sheet of solar screen material, at least one rotating bracket assembly, and at least one adjustable length bracket assembly. The sheet of solar screen material is coupled to the frame. The rotating bracket assembly is coupled to a first portion of the frame to rotationally couple the first portion of the frame to the air conditioning unit. The adjustable length extension bracket assembly is coupled to a second portion of frame to adjustably space the second portion of the frame a predetermined distance from the air conditioning unit.




In another exemplary embodiment, a system for shading an air conditioning unit from sunlight includes at least one frame, at least one sheet of solar screen material, and at least two brackets. The sheet of solar screen material is coupled to the frame. Each bracket is adapted to slidably receive at least a portion of the frame therein and to couple the bracket to the air conditioning unit.




In yet another exemplary embodiment, a kit for modifying an air conditioning unit to include a system for shielding the air conditioning unit from sunlight includes at least one frame, at least one sheet of solar screen material, at least one rotating bracket assembly adapted for rotationally coupling a first portion of the frame to the air conditioning unit, and at least one adjustable extension bracket assembly adapted for coupling a second portion of frame to the air conditioning unit.




In still a further exemplary embodiment, a kit for modifying an air conditioning unit to include a system for shading the air conditioning unit from sunlight includes at least one frame, at least one sheet of solar screen material, and at least two brackets, each of which are adapted to slidably receive at least a portion of the frame therein and to couple the bracket to the air conditioning unit.




In yet a further exemplary embodiment, a method of installing a system for shading an air conditioning unit from sunlight includes providing at least one frame having at least one sheet of solar screen material coupled thereto, providing at least one rotating bracket assembly adapted for rotationally coupling a first portion of the frame to the air conditioning unit, and providing at least one adjustable length extension bracket assembly adapted for coupling a second portion of frame to the air conditioning unit. The rotating bracket and adjustable length extension bracket assemblies are each coupled to the air conditioning unit, the rotating bracket assembly is coupled to the frame first portion, and the adjustable extension bracket assembly is coupled to the frame second portion.




In yet still a further exemplary embodiment, a method of installing a system for shading an air conditioning unit from sunlight includes providing at least one frame having at least one sheet of solar screen material coupled thereto, providing at least two brackets adapted for coupling to the air conditioning unit, each bracket including a first portion adapted to slidably receive at least a portion of the frame therein. The brackets are coupled to the air conditioning unit, and the frame is slidably inserted into the first portion of each of the brackets.




Other independent features and advantages of the preferred shading system and installation method will become apparent from the following detailed description, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS




A perspective view of an embodiment of an air conditioning unit that may be used with the shading system of the present invention is depicted in FIG.


1


. The air conditioning unit


100


is any one of numerous known air conditioners or heat pumps known in the art, and includes various non-illustrated components such as, for example, a compressor, a condenser, various piping and valves, and a fan, all enclosed within a housing


102


.




The air conditioning unit


100


is typically installed outdoors on, for example, a concrete foundation (not illustrated). Thus, as depicted in

FIG. 2

, to shield the housing


102


from the sun's rays, a shading system


200


according to one embodiment of the present invention is installed on the unit


100


. The shading system


200


includes at least one frame


202


. It should be appreciated that the number of frames


200


may be varied to shade as much of the housing


102


as desired. For example, if the air conditioning unit


100


is installed such that only one side of the housing


102


is exposed to sunlight, then only the number of panels (preferably only one) needed to shade that one side of the housing


102


will likely be installed. It should be additionally appreciated that the frame


200


may be formed into any suitable shape and size. However, in the preferred embodiment depicted in

FIG. 2

, the frame is rectangular or square in shape, depending on the shape of the housing sides, and has a top


204


, a bottom


206


, and two sides


208


. In addition, the frame


202


is preferably sized so that substantially one entire side of the air conditioning unit


100


is shaded when the frame


202


is coupled to the housing


102


. The frame


202


may be manufactured from any suitably rigid material such as, for example, wood, stainless steel, and fiberglass, but is preferably manufactured from anodized aluminum.




A sheet of solar screen material


210


is coupled to the frame


202


. The solar screen material


210


may be any one of numerous mesh-type materials of various deflective ratings that are known in the art for deflecting the sun's rays. Preferably, however, the screen material


210


is at least 90-degree highly solar deflective shading mesh. The solar screen material


210


may be coupled to the frame


202


using any one of numerous known devices and methods. For example, the material


210


could be coupled to the frame


202


using various fasteners such as, for example, staples, screws, or nails. Alternatively, an adhesive such as, for example, double-sided tape, epoxy, or glue, could also be used. In the preferred embodiment, however, the material


210


is coupled to the frame by press fitting one or more rubber strips


212


into a groove


214


formed near the inner periphery of each frame


202


. It will additionally be appreciated that more than one sheet of solar screen material


210


may be coupled to the frame


202


to provide additional shading.




Each frame


202


is preferably coupled to the housing


102


using at least two different bracket assemblies. In the depicted embodiment, one bracket assembly is coupled to the top


204


of the frame


202


, and a second bracket assembly is mounted to the bottom


206


of the frame


208


. As illustrated more clearly in

FIG. 3

, a rotating bracket assembly


302


is coupled to the top


204


of the frame


202


. This rotating bracket assembly


302


includes a first housing attachment plate


304


, a first frame attachment brace


306


, and a first hinge


308


. The first housing attachment plate


304


couples the bracket assembly


302


to the housing


102


preferably using one or more threaded fasteners such as, for example, screws


310


. The first frame attachment brace


306


is substantially U-shaped in cross-section and is dimensioned to snap-fit onto the top


204


of the frame


202


. The first frame attachment brace


306


may additionally include one or more openings


312


, which allows the first brace


306


to be additionally secured to the frame


202


using one or more screws (non-illustrated). The first hinge


308


rotationally couples the first attachment plate


304


and first frame attachment brace


308


together. Thus, when the frame


202


is coupled to the housing


102


using the rotating bracket assembly


302


, the frame


202


may be rotated outwardly, away from the side of the housing


102


that it covers. It will be appreciated that the bracket assembly


302


depicted and described herein is merely exemplary of a preferred embodiment and that numerous other rotating bracket assemblies of differing configurations may also be used.




Turning now to

FIGS. 4 and 5

, it can be seen that the second bracket assembly is an adjustable length extension bracket assembly


402


. The extension bracket assembly


402


, as was noted above, is preferably coupled between the bottom


206


of the frame


202


and the housing


102


. The extension bracket assembly


402


is configured such that its length is adjustable to a predetermined, desired position, and held in place in this position. This allows the shading system


200


to provide sufficient shading without substantially obstructing air flow into the unit


100


, or being sucked up against the housing


102


while the unit


100


is operating. As shown more clearly in

FIG. 5

, in the preferred embodiment, the extension bracket assembly


402


includes a first bracket


404


, a second bracket


406


, and fastener hardware


408


. The first bracket


404


has a first end


410


, a second end


412


, a top surface


413


, and a bottom surface


415


. The first end


410


is adapted for coupling the first bracket


404


to the air conditioning unit housing


102


. In the preferred embodiment, this is done by rotationally coupling a second housing attachment plate


414


to the first bracket first end


410


, preferably via a second hinge


416


. The second housing attachment plate


414


, similar to the first housing attachment plate


304


, couples the first bracket


404


to the housing


102


preferably using one or more threaded fasteners such as, for example, screws.




The second bracket


406


, similar to the first bracket


404


, includes a first end


418


, a second end


420


, a top surface


422


, and a bottom surface


424


. The second bracket first end


418


is adapted for coupling the second bracket


406


to the frame


202


. In the preferred embodiment, this is done by rotationally coupling a second frame attachment brace


426


to the second bracket first end


418


, preferably via a third hinge


428


. The second frame attachment brace


426


is configured similar to the first attachment brace


306


. Thus, it is substantially U-shaped in cross section and is dimensioned to snap fit onto the bottom


206


(or other portion) of the frame


202


. Similar to the first attachment brace


306


, the second attachment brace


326


may also include one or more openings, which allows the second attachment brace


426


to be additionally secured to the frame


202


using one or more screws (unillustrated). The second bracket


406


additionally includes a slot


430


formed through it between the top


422


and bottom


424


surfaces, and that extends from a first predetermined position proximate the first end


418


to a second predetermined position proximate the second end


420


. It will be appreciated that the first and second predetermined positions may be any one of numerous positions along the length of the second bracket


406


, depending upon the lengths it is desired to have the adjustable length extension bracket assembly


402


adjustable between.




The fastener hardware


408


, which in the depicted embodiment is a threaded stud


432


and wing nut


434


combination, is coupled to the first bracket


404


and is used to secure the first


404


and second


406


brackets at predetermined positions relative to one another. In particular, the threaded stud


418


extends through the slot


430


, and then when the first


404


and second


406


brackets are adjusted so that the extension bracket assembly


402


is at a desired length, the wing nut


434


is threaded around the stud and tightened against the second bracket top surface


422


. Thus, the first


404


and second


406


brackets are held in place in their relative positions. In the preferred embodiment, the threaded stud


432


is attached to the first bracket


404


by, for example, a welding process. It will be appreciated that the stud


432


need not be attached to the first bracket


404


and could instead be inserted through an aperture formed in the first bracket


404


.




As

FIG. 5

additionally illustrates, in the preferred embodiment, the first


404


and second


406


brackets are each substantially U-shaped in cross section, and the first bracket


404


slidingly moves within the U-shaped cross section of the second bracket


406


to adjust the extension bracket assembly


402


to the desired length. It will be appreciated that this cross sectional shape is merely exemplary of a preferred embodiment, and that other cross sectional shapes could also be used. Additionally, while the first bracket


404


slides within the second bracket


406


, it should be appreciated that the brackets could be configured oppositely. That is, the brackets could be configured such that the second bracket


406


slides within the first bracket


404


. Moreover, while in the preferred embodiment the fastener hardware


408


is included with the first bracket


404


and the slot


430


is included in the second bracket


406


, it should be appreciated that the present invention is not limited to this configuration. For example, the slot


430


could be formed in the first bracket


404


and the fastener hardware


408


could be included with the second bracket


406


. It should additionally be appreciated that the use of a threaded stud


432


and nut


434


is only exemplary of the preferred configuration for holding the extension bracket assembly


402


at a predetermined length, and that various other configurations for performing this same function could be used.




With reference now to

FIG. 6

, an alternative embodiment of a shading system will be described. This shading system


600


, like the previous system


200


, includes at least one frame


602


with one or more sheets of solar screen material


610


coupled to it. The frame


602


and material


610


may be shaped and manufactured similar to the first system


200


, and will therefore not be further described in detail. With this alternate system


600


, however, each frame


602


is coupled to the housing


102


using a different type of bracketing arrangement. In particular, as illustrated more clearly in

FIG. 7

, the bracket


700


used to couple the frame


602


to the housing


100


includes a mounting section


704


and a frame clamping section


706


. The mounting section


704


is used to couple the bracket


700


to the housing


100


, and preferably includes an opening


708


through which a threaded fastener


710


may be installed. The frame clamping section


706


is generally U-shaped in cross-section and is dimensioned to slidably receive the frame


602


. Preferably, as shown more clearly in

FIG. 6

, two brackets


700


are used to couple each side


608


of the frame


602


to the housing


102


, though it should be appreciated that more or less than two per side could also be used. With this particular configuration, the frame


602


may be readily slid into and out of the brackets


700


.




In one embodiment, the shading systems


200


,


600


may be obtained as a kit. Examples of such kits are illustrated in

FIGS. 8 and 9

, respectively. Preferably, each kit


800


,


900


includes, respectively, one or more suitably shaped frames


202


,


602


, one or more sheets of solar screen material


210


,


610


, appropriate bracketing


302


,


402


,


700


, and may additionally include mounting hardware, such as screws


310


,


708


. Although the sheets of solar screen material


210


,


610


are depicted as being pre-coupled to the frame


202


,


602


as part of the kit


800


,


900


, it will be appreciated that the person installing the system


200


,


600


may have to couple the material


210


,


610


to the frame


202


,


602


. Additionally, while it is preferable that the frames


202


,


602


are pre-assembled, the installer may also need to assemble these components, as well. Each kit


800


,


900


may also include other appropriate tools and/or components necessary to install the system


200


,


600


on the unit


100


. The kits


800


,


900


may also include an appropriate container


802


,


902


for shipping, storage, or other purposes.




As noted above, the frames


202


,


602


are preferably pre-assembled and the solar screen material


210


,


610


is preferably pre-coupled to the frame


202


,


602


. Thus, to install the first system


200


, one or more of the rotating brackets


302


and one or more of the adjustable length bracket assemblies


402


are each coupled to one or more sides of the air conditioning unit housing


102


, preferably using one or more screws


310


and


415


, respectively. A frame


202


is then snap fit into the first frame attachment brace


306


on the rotating bracket assembly


302


and into the second frame attachment brace


426


on the adjustable length bracket assembly


402


. The adjustable length bracket assembly


402


may then be adjusted to the desired length so that the bottom


206


of the frame is spaced a desired distance from the air conditioning unit housing


102


, and secured at this length using the fastener hardware


408


. To install the second system


600


, the desired number of brackets


700


are coupled to the air conditioning unit housing


102


. Then, a frame


602


is slid into position within each of the frame clamping sections


706


.




The system and method for shading air conditioning units described herein is relatively easy to install, relatively inexpensive, does not significantly restrict air flow into or out of the air conditioning unit, is adjustable, and attaches directly to the air conditioning unit housing.




While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt to a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
