摘要: In a refrigerating apparatus (1) having application-side heat exchangers (41, 45, 51) for a plurality of systems for air-conditioning, for cold-storage/freezing and the like and a four-way switch valve (3C) and a plurality of check valves (7) on suction sides of compression mechanisms (2D, 2E) and formed from three compressors (2A, 2B, 2C) to allow the operation states to be switched, the number of compressors (2A, 2B, 2C) used at air-conditioning side and cold-storage/freezing side is limited to two at maximum, thereby achieving a simple circuit configuration in which the number of the check valves (7) to be provided in the suction sides of the compression mechanisms (2D, 2E) is reduced to one or two, suppressing the occurrence of chattering noise in check valves (7) and, also, preventing an ability from reducing due to a suction-side pressure loss.
