THERMODYNAMIC ANALYSIS OF HFC R152a REFRIGERANT AS AN ALTERNATIVE TO HFC R134a

A detailed study of thermodynamic properties of an emerging refrigerant R152a has been discussed with respect to other conventional and non-conventional refrigerants like R12, R22, R404a, R410, R134A, etc. More emphasis has been laid on the environmental friendliness of the refrigerant with Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) forming the basis. Further, the optimum working conditions of R152a, in terms of its properties as well as design parameters, are considered and compared with other refrigerants, being used presently, in order to propose it as the most suitable and economically viable substitute to the conventional refrigerants. Lastly, solutions have been suggested to some of the problems of R152a so that it can be used as a replacement for R134a in refrigerators and ACs.
