PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of suppressing deterioration of heating capacity of a heating object fluid caused by frost formation in an evaporator without causing increase in noise.SOLUTION: When it is determined that frost has been formed in an outdoor heat exchanger 14, which is an evaporator, a throttle opening of an electric type expansion valve 13, which is decompression means, is increased so as to become a target throttle opening stored in target value storage means 40c of a control device 40, and refrigerant discharge capacity (rotational frequency) of a compressor 11 is increased so as to become a target refrigerant discharge capacity stored in the target value storage means 40c. Thereby, while suppressing frost formation in the outdoor heat exchanger 14 by increasing refrigerant evaporation temperature in the outdoor heat exchanger 14, deterioration of heating capacity for hot water for supply, which is a heating object fluid, is suppressed. |
