【 摘 要 】

This paper presents a case study of coefficient of performance (COP), exergetic performance and irreversibility of four major components (compressor, condenser, capillary tube and evaporator) of a household refrigerator using R600a and LPG. The results showed that the COP and exergetic efficiency of LPG were 9.5% and 7.1% higher than that of R600a respectively. Also, the total irreversibility of LPG was lower than that of R600a with 22.4%. In general, LPG performed better than R600a in terms of COP, power consumption, exergetic efficiency and irreversibility in the system.
