As per the Montreal Protocol, The, phasing out of ozone depleting refrigerants has led to the quest for ecofriendly alternative refrigerants. HCFC-22(hydro chlorofluorocarbon) is used in window air conditioners. The searchfor alternatives to HCFC22 is a key issue in research. The objective of this work is to review on performance of variousalternative refrigerants with negligible ODP and GWP values. This paper analyzed various parameters like, Coolingcapacity, coefficient of performance, energy consumption, discharge pressure. HC-290 performed better than that ofHCFC22. HFC407C/HC290/HC600a blend refrigerant mixture demanded lengthening of the condenser by 19% in orderto maintain the discharge pressure within acceptable limits. Although Retrofitting with R-407C gave poor performance,it is an option to extend the life of air conditioning units. R1270 system with the compressor of a larger displacement hasbetter performance with negligible loss in EER and great increase in cooling capacity when compared to R290 system.The overall performance of refrigerant mixture of 70% R123 and 30% R290 is superior to that of R12 at all evaporatorconditions studied. R507 retrofitted window air conditioning system had closed performance characteristics to R22.
