Abstract (en)
[origin: EP2578965A1] In a refrigeration apparatus including a refrigerant circuit (20) in which a plurality of compressors (21), a heat-source-side heat exchanger (25), an expansion mechanism (52), and a utilization-side heat exchanger (53) are connected in order, when one or more of the compressors (21) is a compressor in operation and other one or more of the compressors (21) is a stopped compressor, a control is performed to decrease the low pressure of an evaporator connected to the compressor in operation to less than the saturation pressure equivalent to the temperature of the stopped compressor itself or the ambient temperature of the stopped compressor. In such a manner, refrigerant liquefaction in the stopped compressor is reduced or prevented, thereby reducing operation failure or burnout upon a restart.
