Abstract (en)
A supercooling heat exchanger 23 is configured such that a heat exchange ratio which is a ratio of a heat exchange amount in the supercooling heat exchanger 23 to a heat exchange amount in a radiator 22 becomes 0.1 or more and 0.6 or less, when dryness fraction of refrigerant which flows out from an evaporator 25 is adjusted to 0.8 or more and less than 1.0. According to this configuration, an amount of gas phase refrigerant which flows into the evaporator 25 is reduced, a pressure loss in a low pressure side pipe is reduced, and excessive rise of discharge temperature of a compressor 21 is suppressed in a state where the evaporator 25 is efficiently used. Therefore, even at the time of a high air heating load, it is possible to realize energy saving and low global warming potential.
