THERMODYNAMIC CYCLE PERFORMANCE COMPARISON TESTS OF HFC-152A AND HFC-134A WITH CFC-12.

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

Summary

AS A PART OF A JOINT CANADIAN RESEARCH AND DEVELOPMENT PROGRAM INVESTIGATING ENVIRONMENTALLY ACCEPTABLE ALTERNATIVES TO CFC REFRIGERANTS, A SERIES OF TESTS HAS BEEN COMPLETED TO COMPARE THE THERMODYNAMIC PERFORMANCE OF R152A AND R134A WITH R12 ON A DROP-IN BASIS. THE TESTS WERE CARRIED OUT 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 -17.3 TO 7.9 DEG C. A CONSTANT CONDENSING TEMPERATURE OF 51.5 DEG C WAS MAINTAINED, AS WELL AS A CONSTANT DEGREE OF CONDENSER SUBCOOLING AND SUPERHEAT AT THE COMPRESSOR INLET. THE RESULTS ARE GIVEN.
