Electricity generated from diverse energy sources is being studied closely by scientists to reduce its consumption rates in the systems that utilize it. Home refrigerators are one of the products that should be looked into to see if they can be made to consume less electricity. Phase Change Materials (PCMs) are an example of a solution that can store energy in a household refrigerator, lowering electricity use. PCMs are being utilized to improve the efficiency of household refrigerators. PCM materials absorb a significant amount of heat energy when they transition from liquid to solid and release it when they solidify. According to the previous study, using PCMs in household refrigerators resulted in a 72 percent increase in refrigerator performance and a 30 percent reduction in energy use. The present paper sheds light on the published research on the use of the PCMs to improve the performance of the home refrigerator and thus reduce electricity consumption.
