Abstract
Abstract A cabinet-type air-conditioning apparatus including a compressor, a condenser which contains a cooling air circulation system and an evaporator, characterized in that water is sprayed onto the condenser to cool it by the heat of evaporation, and the circulating cooling air entraining evaporated water is passed over the condenser before it is discharged to the outdoor to cool high-temperature gaseous refrigerant compressed by the compressor.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
241 words
In an air-conditioning apparatus contained in a cabinet, having a partition wall to divide the interior of said cabinet into a machine compartment and a cooling compartment, a compressor contained in said machine compartment, an evaporation condenser disposed in said machine compartment, said evaporation condenser being connected to said compressor to condense gaseous refrigerant compressed by said compressor, a water sprinkler included in a water circulation system to spray water onto said evaporation condenser to cool the refrigerant flowing therethrough, an evaporator contained in said cooling compartment, means to cool said evaporation condenser by forced circulation air to remove steam generated by the water sprayed on said evaporation condenser, an exhaust hose to discharge to outdoor said forced circulation air entraining said generated steam, and wherein there is included an air exhaust system constituted by a condenser casing containing said sprinkler and said evaporation condenser, said condenser casing having an exhaust discharge port at its upper end, a duct connected to said discharge port to discharge air after it has been used to cool said evaporation condenser, a fan contained in said duct, and a discharge hose to discharge air to the outdoor by the operation of said fan, the improvement therein wherein there is a heater disposed above said evaporation condenser, said heater being connected to receive high-temperature gaseous refrigerant from said compressor, the relative humidity of the air being decreased by heating the high-temperature gaseous refrigerant in said heater.
Claim 2
Dependent Claim
241 words
In an air-conditioning apparatus contained in a cabinet, having a partition wall to divide the interior of said cabinet into a machine compartment and a cooling compartment, a compressor contained in said machine compartment, an evaporation condenser disposed in said machine compartment, said evaporation condenser being connected to said compressor to condense gaseous refrigerant compressed by said compressor, a water sprinkler included in a water circulation system to spray water onto said evaporation condenser to cool the refrigerant flowing therethrough, an evaporator contained in said cooling compartment, means to cool said evaporation condenser by forced circulation air to remove steam generated by the water sprayed on said evaporation condenser, an exhaust hose to discharge to outdoor said forced circulation air entraining said generated steam, and wherein there is included an air exhaust system constituted by a condenser casing containing said sprinkler and said evaporation condenser, said condenser casing having an exhaust discharge port at its upper end, a duct connected to said discharge port to discharge air after it has been used to cool said evaporation condenser, a fan contained in said duct, and a discharge hose to discharge air to the outdoor by the operation of said fan, the improvement therein wherein there is a heater disposed above said evaporation condenser, said heater being connected to receive high-temperature gaseous refrigerant from said compressor, the relative humidity of the air being decreased by heating the high-temperature gaseous refrigerant in said heater.
Claim 3
Dependent Claim
72 words
The air-conditioning apparatus according to claim 1 wherein said water circulation system comprises a water pan disposed beneath said evaporation condenser to receive water drained therefrom, means to maintain the water in said pan at a substantially constant quantity, a pump disposed in said water pan and said sprinkler being disposed above said evaporation condenser, said sprinkler being connected to said pump to spray water in said pan onto said evaporation condenser.
Claim 4
Dependent Claim
43 words
The air-conditioning apparatus according to claim 2 wherein said means for maintaining said water at a substantially constant quantity comprises a cartridge filled with water, the outer end of said cartridge being dipped in the water of said pan to supply water thereto.
Claim 5
Dependent Claim
46 words
The air-conditioning apparatus according to claim 1 wherein an opening is provided through said cabinet and one end of an intake pipe is connected to said opening for passing said forced cooling air, the opposite end of said air intake pipe being opened to the outdoor.
Claim 6
Dependent Claim
39 words
The air-conditioning apparatus according to claim 4 wherein said air intake pipe is disposed in concentric relationship with said discharge hose so that cooling air is sucked through a space between said air intake pipe and said discharge hose.
Claim 7
Dependent Claim
24 words
The air-conditioning apparatus according to claim 4 wherein a booster including a fan is connected to the outdoor end of said air intake pipe.
Claim 8
Dependent Claim
172 words
An air-conditioning apparatus comprising: a. a cabinet; b. a partition wall in said cabinet to divide the interior of said cabinet into a machine compartment and cooling compartment; c. a compressor contained in said machine compartment; d. an air exhaust system having a condenser casing provided with a discharge port at its upper end and containing an evaporation condenser, a water sprinkler and a heater, said evaporation condenser being disposed in the machine compartment and connected to the compressor, said water sprinkler being included in a water circulation system to spray water onto said condenser to cool a refrigerant flowing therethrough, said heater being disposed above said sprinkler and connected to said compressor to receive therefrom hot gaseous refrigerant, so that the relative humidity of the air is decreased; e. a duct connected to said discharge port for discharging the air after said evaporation condenser has been cooled including a fan contained in said duct; and, f. a discharge hose to discharge air to the outdoor by the operation of said fan.
Claim 9
Dependent Claim
172 words
