Abstract
Though the global warming up potential of HFC134a is relatively high, it is affirmed that it is a long term alternative refrigerants in lots of countries. The different environmental friendly refrigerants of either HC & HFC class.HCs have zero ODP and very low GWP whereas HFCs have zero ODP but a higher GWP. When R-134a was replaced with blending of HCs refrigerant the COP of the system improved. In this paper consider the Theoretical analysis of R134a, R290, R600a & various ratios of R290/R600a refrigerants. The present investigation has been done for evaporator and condenser temperatures in the range of-10oc and 40oc respectively. The results indicate that the refrigerant blend (R600a/R290) with 70/30 mass fraction was found to be the most suitable alternative among refrigerants tested for R134a.
