Abstract

The refrigeration system disclosed herein operates at least one evaporator in a low temperature environment. A condenser is provided for rejecting heat into the environment. Refrigerant from the condenser is provided to a refrigerant processing vessel which allows a mixture of gas and liquid phase refrigerant to separate. A heat exchanging conduit is submerged in the liquid phase refrigerant in the lower portion of the processing vessel and the outlet of a compressor serving the low temperature evaporators is connected to the inlet end of that conduit. Liquid phase refrigerant from the processing vessel is provided to the low temperature evaporators. An intake is provided in the upper portion of the processing vessel for drawing off gas phase refrigerant and that intake and the outlet end of the heat exchanging conduit are connected together and to the inlet side of a compressor driving refrigerant through the condenser.
