<P>PROBLEM TO BE SOLVED: To provide a refrigerating cycle device capable of detecting reverse rotation of a compressor with an inexpensive structure. <P>SOLUTION: The refrigerating cycle device includes: a refrigerant circuit 8 which is configured by circularly connecting a compressor 1, a radiator 2, a pressure reducing mechanism 3 and an evaporator 4, and in which a refrigerant is circulated; a control device 9 with a compressor control means 10 of the compressor 1; and a discharge temperature detection means 7 for detecting a temperature of the refrigerant discharged from the compressor 1. When the compressor 1 is driven for a predetermined time by the control device 9 and the change of the discharge temperature to be detected by the discharge temperature detection means 7 is smaller than a preset threshold, the reverse rotation (abnormal rotation direction) of the compressor 1 is determined. <P>COPYRIGHT: (C)2012,JPO&INPIT |
