PROBLEM TO BE SOLVED: To provide a refrigerating cycle device capable of suppressing the lowering of a temperature of a compressor, and capable of being operated with high energy efficiency.SOLUTION: The refrigerating cycle device includes: a refrigerant circuit 5 where a compressor 1, a radiator 2, a pressure reducing mechanism 3, and an evaporator 4 are connected in this order so that a refrigerant can be circulated; an evaporator temperature detecting means 12 for detecting a temperature of the evaporator 4, and control devices (11, 13). When a detection temperature detected by the evaporator temperature detecting means 12 after the lapse of a predetermined time from the start of defrosting operation for eliminating frost adhered to the evaporator 4 is lower than a prescribed temperature, a circulation amount of the refrigerant circulated in the refrigerant circuit 5 is increased, and the refrigerating cycle device can be operated with high energy efficiency. |
