While operating compressors and suspended compressors are mixed in the compressors (21), control of reducing the low pressure of the evaporator connected to the operating compressors to be lower than the saturated pressure equivalent to the temperature of the suspended compressor bodies or the surrounding of the same prevents the cooling medium from coming into the dormant state in the suspended compressors, which suppresses malfunction and burning out when restarted.
