Abstract:
Two heat pump cycles operating with halogenated
hydrocarbon mixtures are considered. Each Coefficient of
Performance (COP) increases up to 50% under extreme
temperature lifts when reciprocating compressors are
employed. This is due to a reduction of the pressure
ratio by a factor of more than two.
