Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a refrigeration cycle device that can detect inverse rotation of a compressor with a low-cost configuration.SOLUTION: A refrigeration cycle device includes: a refrigerant circuit 9 which connects circularly a compressor 1, a radiator 2, a decompression mechanism 3, and an evaporator 4, and in which a refrigerant circulates; and a discharge temperature detecting means 7 for detecting each temperature of a control device 10 with a compressor controlling means 11 of the compressor 1 and the refrigerant discharged from the compressor 1, wherein the compressor 1 is driven by the control device 10 for a predetermined period, and inverse rotation of the compressor 1 (an abnormal rotation direction) is determined when a discharge temperature variation detected by the discharge temperature detecting means 7 is less than a predetermined threshold value.
