PROBLEM TO BE SOLVED: To provide a refrigerating device capable of effectively reducing power of a compressor. SOLUTION: A refrigeration circuit 11 has an oil separator 60 for separating oil from a high pressure refrigerant, a cooling means 73 for cooling the oil separated by the oil separator 60, and an oil supply circuit 70 for supplying the cooled oil to the compressor 20. The oil supply circuit 70 has a recovery mechanism 40 for recovering energy of the oil separated by the oil separator 60. In the compressor 20, the refrigerant is cooled by the oil and the power of the compressor 20 is reduced. At the same time, the recovery mechanism 40 recovers energy consumed by the compressor 20 to increase the pressure of the oil. COPYRIGHT: (C)2010,JPO&INPIT
