The potential of HFC-134a and HFC-152a to replace CFC-12 in medium temperature heat pump applications.

Author(s) : LINTON J. W., SNELSON W. K., HEARTY P. F., et al.

Summary

The tests were conducted in a well instrumented water-water heat pump test facility, using an open-drive reciprocating compressor and counter flow heat exchangers. Test measurements covered an evaporating temperature range from 11 to 34 deg C. A constant refrigerant condensing temperature of 70 deg C was maintained throughout the tests. Tests were controlled to maintain a constant degree of condenser subcooling and superheat at compressor inlet. Test data were used to compare important performance characteristics of the three refrigerants including heating capacity, heating coefficient of performance, refrigerant mass flow, compressor shaft power, and volumetric refrigerating capacity.
