Abstract
In a phase-change refrigeration circuit including a compressor, condenser and evaporator and connecting conduits all charged with a phase-change refrigerant, each of the compressor, condenser and evaporator having an input and output, the improvement comprising a heat exchanger including a container filled with a liquid convection fluid with the container enclosing a portion of the circuit such that the convection fluid is in heat-conducting relation to the system refrigerant flowing through the said enclosed portion. One such heat exchanger filled with convection fluid may be disposed between the compressor and the condenser of the system to enclose the conduit extending therebetween. Another such heat exchanger container filled with convection fluid may be used to enclose the evaporator of a high-stage circuit and the condenser of the low-stage circuit, the high-stage and low-stage being cascaded together. Additional by-passing conduits may be provided to by-pass either the condenser or the evaporator of the circuit and a portion of the by-pass conduit means may be in heat-conducting relationship to the convection fluid in the heat exchanger.
