ABSTRACT:
Scavenging is applied to a conventional refrigeration cycle to return most of the energy normally remaining in a warm condensed liquid to the cycle. This permits considerably more energy to be picked up in the evaporator of the cycle than under conventional practice. The concept is applicable to any type positive displacement compressor where an intake of evaporator generated gas can be trapped in the compressor, with the scavenged gas then added prior to mechanical compression. The concept is particularly applicable to reciprocating compressor type heat pump systems.
