dc.description.abstractIn this study, second law analysis of environmentally friendly R2901R600/R600a mixture at a rate of 45/46/9 % by mass fraction has been experimentally executed on a water-cooled heat pump as a substitute for HFC134a at varying air and water mass flow rates. Experimental outputs indicate that the heat pump system shows the highest exergy efficiency at 0.040 kg s-1 of water mass flow rate and 0.1 kg s-1 of air mass flow rate running with both R134a and HC mixture. Even though proposed HC mixture has lower COP and rational efficiencies, cooling exergy efficiency of HC mixture is 2-3% better than that of R134a. Higher energy consumption and lower rational efficiencies can be resolved by a hermetic compressor with higher sweep volume which is compatible with pure and mixture hydrocarbons.en_US
