dc.description.abstractAn Exergy method for theoretical analysis of a traditional vapor-compression refrigeration system equipped with liquid vapour heat exchanger (lvhe) for refrigerants like R134a, R423A, R507A, R1233zd(E), R1234ze(Z), R1234ze(E) and R1243zf were carried out. All are ultra-low GWP and zero ODP refrigerants and comparison of the results with HFC-134a refrigerant as possible alternative replacements in Automotive air-conditioning and stationary refrigeration is presented. A mathematical computational model has been developed for calculating Coefficient of performance (COP), exergetic efficiency, exergy destruction and efficiency defects for the above mention refrigerants. During the investigation, condenser temperature is kept at 313K and 323K, evaporator temperature is kept in the range from 223K to 273K. Results obtained for selected condenser temperature are compared and discussed elaborately. It indicates that R1234ze(Z) can be a good drop-in replacement of HFC-134a and R1234ze(Z) can replace the HFC-134a after some modifications as the results are almost similar. Among the system components, evaporator shows highest efficiency defect value and liquid vapor heat exchanger shows the lowest.en_US
