<P>PROBLEM TO BE SOLVED: To enhance the super cooling performance of a heat exchanger which performs a heat dissipation operation at heating. <P>SOLUTION: This indoor heat exchanger (25) comprises a heat conductive pipe group (30) composed of a plurality of heat conductive pipes (31) which are arranged at prescribed intervals, and is objective for a heat exchanger arranged in a refrigerant circuit (20) which performs a cooling cycle. The heat conductive pipes (31) are arranged in a first pipe row (30a) and a second pipe row (30b), and on the other hand, the heat conductive pipe group (30) comprises a first heat conductive pipe group (33) and a second heat conductive pipe group (34) which are arranged so that a refrigerant flows in from the heat conductive pipe (31) in the first pipe row (30a), and the refrigerant flows out from the heat conductive pipe (31) in the second pipe row (30b) at refrigerant heat dissipation, and a third heat conductive pipe group (35) which super-cools the heat dissipation refrigerant at the refrigerant heat dissipation, and the third heat conductive pipe group (35) is arranged while making a suppression region (37) for suppressing heat conductivity exist between the second heat conductive pipe group (34) and itself. <P>COPYRIGHT: (C)2013,JPO&INPIT |
