PROBLEM TO BE SOLVED: To provide a refrigerating cycle system capable of satisfying a plurality of demands of high capacity, a high compressing pressure ratio and power saving. SOLUTION: This refrigerating cycle system 10A includes two compressors 20A, 20B, and can select an operation mode from serial operations, parallel operations, and individual operations of either of these operations of the compressors 20A, 20B by switching valves 70A, 70B and 70C. Thus the system can flexibly cope with a demand for a large capacity, a demand for a high compression pressure ratio, and a demand for power saving. COPYRIGHT: (C)2009,JPO&INPIT
