Abstract
A refrigerating machine equipped with a compressor has an intermediate-pressure portion in which refrigerant having intermediate pressure higher than the pressure of the refrigerant at the suction side of the compressor and lower than the pressure of the refrigerant at the discharge side of the compressor is allowed to be introduced, and a heat exchange circuit formed between a heat-source side heat exchanger and a using side heat exchanger. The heat exchange circuit branches the refrigerant flowing from any one of the heat exchangers to the other heat exchanger, carries out heat exchange between one branched refrigerant and the other branched refrigerant or the refrigerant before the branching so that the one branched refrigerant is set to gas-phase refrigerant, and the gas-phase refrigerant thus achieved is led to any one of the intermediate-pressure portion and refrigerant suction pipe of the compressor.
