In developing countries like India there exists a widespread general problem of frequent power cuts, which gives rise to spoilage of perishable items such as medicine and food stuff due to lack of a passive cold retention system. Moreover, there exists the pressing need of the hour to incorporate eco-friendly practices from the grass root level, while at the same time conserving energy and increasing efficiency. In this paper the effects of phase change material (PCM) on performance of a household refrigerator with R290/R600 blend as refrigerant has been investigated experimentally. Theoretical analysis was carried out using Cool pack software. Experimental results with PCM show that the addition of thermal inertia globally enhances heat transfer from the evaporator and allows a higher evaporating temperature, which increases the coefficient of performance (COP) of the system. The energy stored in the PCM is yielded to the refrigerator cell during the off cycle and allows for several hours of continuous operation without power supply. The experimental results with PCM also confirm that, average compressor running time is reduced about 5-30% as compared to without PCM, and the test results with PCM prove a noticeable reduction of the temperature fluctuation inside the cabinet.
