Abstract

The coefficient of performance (COP) and exergetic performance of a household refrigerator was investigated using R134a in comparison with the performance of R600a. The coefficient of performance, exergy efficiency, and the efficiency defect in the four major components were investigated. The results showed that the COP of R600a was 10.3% higher than that of R134a, a higher exergy efficiency of 42.8% was obtained using R600a at evaporator temperature of –10oC. Generally, R600a performed better than R134a in terms of COP, exergy efficiency, and the efficiency defect in a household refrigeration system.
