Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
213 words
An apparatus for air conditioning the interior of a building comprising: a refrigeration appartus comprising a first coil for the movement of a refrigerant therethrough and a fan motor for directing a stream of atmospheric air over said first coil for cooling the refrigerant, a pair of spaced axially arranged chambers, means for providing an air inlet port in the surface of one of said chambers and an air outlet port in the surface of the other of said chambers, the inner chamber of said pair of chambers being provided with at least one opening covered by a fibrous material, means for selectively wetting said fibrous material with water, a secoond coil connected to said first coil and juxtapositioned to and downstream of said fibrous material for conducting the refrigerant from said first coil therethrough in a closed circuit configuration, air movement means connected to said apparatus for directing said air passing over said first coil into one of said chambers, through said fibrous material and over said second coil out said outlet port, said air being cooled by water evaporation when passing through said fibrous material, and means for directing said air cooled by water evaporation between the interior and exterior walls of a building to reduce the temperature of these walls.
Claim 2
Independent Claim
213 words
An apparatus for air conditioning the interior of a building comprising: a refrigeration appartus comprising a first coil for the movement of a refrigerant therethrough and a fan motor for directing a stream of atmospheric air over said first coil for cooling the refrigerant, a pair of spaced axially arranged chambers, means for providing an air inlet port in the surface of one of said chambers and an air outlet port in the surface of the other of said chambers, the inner chamber of said pair of chambers being provided with at least one opening covered by a fibrous material, means for selectively wetting said fibrous material with water, a secoond coil connected to said first coil and juxtapositioned to and downstream of said fibrous material for conducting the refrigerant from said first coil therethrough in a closed circuit configuration, air movement means connected to said apparatus for directing said air passing over said first coil into one of said chambers, through said fibrous material and over said second coil out said outlet port, said air being cooled by water evaporation when passing through said fibrous material, and means for directing said air cooled by water evaporation between the interior and exterior walls of a building to reduce the temperature of these walls.
Claim 3
Dependent Claim
51 words
The apparatus set forth in claim 1 wherein: said air movement means comprises an electrically operated blower mounted within said inner chamber for drawing air through said inlet port in the outer chamber, said fibrous material and said second coil and out of said outlet port formed in the inner chamber.
Claim 4
Dependent Claim
71 words
The apparatus set forth in claim 1 wherein: said air movement means comprises a suction fan mounted in the space between said chambers for drawing air through said air inlet port formed to extend through the outer chamber into the inner chamber of said pair of chambers and through said fibrous material and over said second coil and out an output port in one of the surfaces of said outer chamber.
Claim 5
Dependent Claim
82 words
The apparatus set forth in claim 1 wherein: the inner chamber of said pair of chambers is provided with the air inlet port extending through a surface of the outer chamber of said pair of chambers, and said air movement means comprises a blower mounted in said inlet port, whereby air drawing into said inner chamber by said blower is forced through said fibrous material, said coil and out the outlet port formed in one of the surfaces of said outer chamber.
Claim 6
Dependent Claim
83 words
The apparatus set forth in claim 1 in further combination with: a first control means for selectively energizing said air movement means for moving air and for energizing said air wetting means for cooling air moving therethrough, a second control means for selectively moving air through the apparatus at a greater or lesser cubic feet per minute rate, and a third control means for wetting or not wetting said fibrous material in response to the temperature of the refrigerant in said coil first.
