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, and an oil supply circuit 70 for supplying the oil separated by the oil separator 60 to a compressing mechanism 20 to cool the oil in a compressing stroke of the compressing mechanism 20. In the oil supply circuit 70, a recovery mechanism 40 for recovering energy of the oil separated by the oil separator 60 is disposed. In the compressing mechanism 20, the refrigerant is cooled by the oil so as to reduce the power of the compressing mechanism 20. At the same time, the recovery mechanism 40 recovers power consumed by the compressing mechanism 20 to increase the pressure of the oil. COPYRIGHT: (C)2010,JPO&INPIT |
