<P>PROBLEM TO BE SOLVED: To obtain enough heating performance even just after starting. <P>SOLUTION: This refrigerator is constituted to make the pressure of a high pressure refrigerant at a predetermined pressure or higher by a constant pressure control valve 90 when the high pressure refrigerant discharged from a compressor 10 is supplied into a second indoor heat exchanger 32. Thereby, the heating performance can be increased since the heating ability, or heating ability of the second indoor heat exchanger 32 is restrained from changing even when changing the thermal load conditions on the high pressure side and low pressure side. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
