An exergy analysis is usually done to improve the system and find out the sites of work lost. The sites having high exergy destruction indicates the scope of improvement in specific sites in order to achieve overall improved, efficient system. This research work investigates the losses involved in process and overall cycle due to irreversibility in vapour compression refrigeration system with evaporator temperature as influential parameter by exergy destruction and second law efficiency

From exergy analysis, second law efficiency increases with evaporator temperature and exergy destruction decreases with increase in evaporator temperature and exergy loss for R-12 and R-22 are almost same but R-407C is maximum, exergetic efficiency is maximum for R-12 then R-22 and minimum for R-407C.
