<P>PROBLEM TO BE SOLVED: To provide a vapor compression type refrigerating cycle capable of improving coefficient of performance (COP) by introducing a refrigerant discharged by a part of compressors to a plurality of radiators. <P>SOLUTION: This refrigerating cycle 1 is provided with a communication pipe 203 for communicating a first pipe 201 and a second pipe 202, and an opening and closing valve 204 for opening and closing a communication passage in the communication pipe 203. A control device 100 stops one of the compressors, operates the other compressor, and opens the opening and closing valve 204, when a discharge rate of the refrigerant of at least one of the first compressor 11 and the second compressor 21 is reduced to a prescribed rate based on a stable operating state of the compressors. <P>COPYRIGHT: (C)2008,JPO&INPIT |
