Air-conditioning apparatus

Abstract

An air-conditioning apparatus includes a housing, an evaporator, a condenser, and a water sprinkler for sprinkling condensed water to the condenser, the condensed water having been generated at the evaporator. The condenser includes a first header and a second header arranged parallel to each other, a first heat transfer tube and a second heat transfer tube that are arranged parallel to each other and are arranged between the first header and the second header, and a fin disposed between the first heat transfer tube and the second heat transfer tube.

1 . An air-conditioning apparatus, comprising:
 a housing having a first air path through which indoor air passes and a second air path through which outdoor air passes;   an evaporator disposed in the first air path and configured to exchange heat between the indoor air and refrigerant;   a condenser disposed in the second air path and configured to exchange heat between the outdoor air and the refrigerant; and   a water sprinkler configured to sprinkle condensed water to the condenser, the condensed water being generated at the evaporator,   the condenser including   a first heat transfer tube and a second heat transfer tube that are arranged parallel to each other,   a fin arranged between the first heat transfer tube and the second heat transfer tube,   a first header, and   a second header arranged parallel to the first header,   the first heat transfer tube and the second heat transfer tube being arranged parallel to each other and being arranged between the first header and the second header,   a top of the first header being a slope inclined to a horizontal plane.   
     
     
         2 . (canceled) 
     
     
         3 . The air-conditioning apparatus of  claim 1 ,
 wherein the first header and the second header extend in a horizontal direction,   the first header is located higher than the second header, and   the water sprinkler is configured to sprinkle the condensed water onto a top of the first header.   
     
     
         4 . The air-conditioning apparatus of  claim 1 ,
 wherein, when the condenser is viewed from above, an end portion of the fin protrudes from an edge of the first header.   
     
     
         5 . (canceled) 
     
     
         6 . The air-conditioning apparatus of  claim 1 ,
 wherein the second header has a water-storage portion that is a depression in a top of the second header.   
     
     
         7 . The air-conditioning apparatus of  claim 1 ,
 wherein the first header, the second header, the first heat transfer tube, the second heat transfer tube, and the fin are made of aluminum.   
     
     
         8 . The air-conditioning apparatus of  claim 1 ,
 wherein the fin is a corrugated fin.   
     
     
         9 . The air-conditioning apparatus of  claim 1 ,
 wherein the evaporator includes   a plurality of evaporator-side heat transfer tubes through which the refrigerant flows, and   a plurality of evaporator-side fins connected to the plurality of evaporator-side heat transfer tubes, and   the plurality of evaporator-side heat transfer tubes and the plurality of evaporator-side fins are made of aluminum.   
     
     
         10 . The air-conditioning apparatus of  claim 1 , comprising
 a refrigerant circuit in which a compressor, the condenser, an expansion valve, and the evaporator are connected to each other via refrigerant pipes to enable the refrigerant to circulate,   wherein the refrigerant pipes are made of aluminum.   
     
     
         11 . The air-conditioning apparatus of  claim 1 , comprising
 an ion-exchange resin for removing a metal that is nobler than aluminum and is contained in the condensed water generated at the evaporator.
