Comparative assessment of HFC134a and some refrigerants as alternatives to CFC12
Abstract A composite plot relating evaporating temperature T EV , condensing temperature T CO , pressure ratio (PR) and theoretical Rankine coefficient of performance (COP) RR is presented for HFC134a. The theoretical performance of HFC134a has been comparatively assessed along with HCFC22, HFC134, HFC152a, HCFC124 and HCFC142b as alternatives to CFC12 by using the standard refrigeration parameters including pressure ratio, specific compressor displacement, theoretical Rankine coefficient of performance, shaft power per ton of refrigeration. A discussion of the practical implications of the choice of the alternatives to CFC12 is also presented.
