Abstract
A refrigerating machine equipped with a compressorhaving an intermediate-pressure portionM in which refrigerant having intermediate pressure higher than the pressure of the refrigerant at the suction side thereof and lower than the pressure of the refrigerant at the discharge side thereof can be introduced, and an intermediate-pressure receiverthat is inserted in a flow path between an expansion valve() of a heat source side heat exchanger() and an expansion valve() of a using side heat exchanger(), carries out gas-liquid separation on gas-liquid mixed refrigerant after the heat exchange in the heat source side heat exchanger or the using side heat exchanger, and then feeds gas-phase refrigerant to the intermediate-pressure portionM.
