In a single circuit refrigeration plant, a refrigerant gas stream while flowing in the circuit is compressed by a compressor, circulated from the pressure side of the compressor through a condenser, then an evaporator and finally back to the suction side of the compressor. A housing is provided having two concentrically located contiguous compartments. Of these, the first compartment is interposed between the pressure side of the compressor and the condenser. The second compartment is interposed between the first compartment and the refrigerant gas return line to the suction side of the compressor. In the first compartment, the compressed refrigerant is degassed and forwarded to the condenser and the separated oil, still having some gas dissolved in it is forwarded under pressure to the second compartment. There, the pressure is released, the oil is degassed and returned to the compressor and the separated gas is combined with the refrigerant return line from the evaporator to the suction side of the compressor. While the degassed separated oil is in the second compartment, it is cooled by indirect heat exchange with the atmosphere surrounding the second compartment.
