ABSTRACT:
In a cascade refrigeration system where low pressure vapor from an evaporator stage is compressed and then recycled for condensation to the evaporator of a previous stage, the improvement of passing the low pressure vapor from an evaporator stage through a heat exchanger to heat said vapor to ambient temperature, compressing said heated vapor, removing the compressor work by passing said compressed vapor through a cooler, cooling said compressed vapor by passing it through said heat exchanger in heat exchange relationship with said low pressure vapor, condensing it in the evaporator of the next higher temperature cycle of the cascade system and recycling the liquid to the low pressure evaporator stage.
