Energy Analysis Of Vcr -system With Mint Gas, R-12,and R-134a

A domestic refrigerator designed to work with R-134a was investigated to assess the possibility of using a mixture of propane and iso- butane (Mint Gas). The performance of the refrigerator using azotropic mixture as refrigerants was investigated and compared with the performance of refrigerator when R-134a, R12, is used as a refrigerant. The effect of Condenser Temperature and Evaporation Temperature on Coefficient of Performance, refrigerant effect, work of compressor and heat rejection ratio where investigated. The energy consumption and C.O.P of hydrocarbons and there blends shows that hydrocarbons can be used as refrigerants in the domestic refrigerator. The exergy analysis of mixture of propane and isobutene (mint gas) with R-12 and R-134a. The cycle considered for study is having super heated vapour after compression. Efforts have been made to consider sub cooling also.
