Abstract (en)
[origin: EP2320164A2] A refrigeration cycle apparatus 1 includes: a refrigerant circuit 2 including a condenser 22 and a subcooling heat exchanger 23; and a bypass passage 3 that extends through the subcooling heat exchanger 23. In the bypass passage 3, a dryness fraction of the refrigerant that has flowed out of the subcooling heat exchanger 23 is adjusted. Since the subcooling heat exchanger 23 is configured appropriately, a ratio of an amount of heat exchange between, in the bypass passage 3, the refrigerant decompressed by the bypass expansion means 31 and the refrigerant passing through the refrigerant circuit 2 with respect to an amount of heat exchange between, in the condenser 22, the refrigerant that has flowed into the condenser 22 and a fluid to be heated falls in a specified range even during the operation using the adjusted dryness fraction. As a result, the subcooling effect of the subcooling heat exchanger 23 is secured.
