Abstract: Effects of Phase Change Material (PCM) on compressor on/off cycle of a household refrigerator have been investigated experimentally. PCMs are used behind the five sides of the evaporator cabinet and the evaporator coil is immersed in the PCM. Three types of PCMs at different thermal loads have been used for the investigation. Experimental results for the system with PCM show that the number of compressor on/off cycle within the tested time is reduced significantly. Depending on the types of PCM, the number of compressor on/off cycle for the system with PCM is around 3-5 times lower than that of the system without PCM. This reduction of compressor on/off cycle ultimately reduces the efficiency losses of the system as compared to a conventional refrigeration system. The experimental results with PCM also confirm that average compressor running time per cycle is reduced significantly and it is found about 2-36% as compared to without PCM.
