“…The main reason is that it enhances heat transfer from the evaporator and also it can store excess cooling capacity of the system in the PCM [40]. Besides, this configuration results in higher evaporator temperature and pressure during phase change period of PCM [39]. Thus, refrigerant density is higher and, as a result, cooling capacity increases.…”

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. Keywords PCM, COP, Evaporator, condenser IntroductionRefrigeration systems are used in household appliances, including refrigerators in homes, industrial freezers, and air conditioning. A compressor consumes the most energy. (Pirvaram et al., 2019) Domestic refrigerators are the most used household appliances. These appliances consume more residential electricity throughout the year. The primary issue is to enhance the energy efficiency of the domestic refrigerator. We can overcome this issue by improving the coefficient of performance(COP) of a domestic refrigeration system. (Prashanth et al., 2019) Improving the efficiency of household refrigerators, which includes compressor refrigerators broadly, thermal load, ambient temperature, and the refrigerant used. (Karthikeyan et al., 2020), has a substantial impact on rating power consumption. The refrigeration cycle can be enhanced by using a high-performance compressor that can directly impact the COP of the cooling system or using other advanced thermal insulation techniques. Much research has been conducted using various approaches to shorten compressor working time. A few investigations have been done with PCM in the evaporator section and PCM in the condensing coil.

“…The leading purpose of that, is the proven heat transfer rate from the evaporator, Moreover, PCM can reserve extra cooling capacity of the system (Visek et al, 2014). As well as, resulting in larger evaporator temperature and pressure during phase change period of PCM (Rahman, 2013). As a result of incorporating PCM(s), the compressor needs to work for a longer time period to charge the energy storage.…”

In this study, a refrigeration system developed by phase change material, PCM, is compared to a conventional refrigerator. Equal thermal loads (i.e. water) are gripped by the evaporator cabinet at different height levels apart from the evaporator surface. In the modified refrigerator, different PCMs are attached to the bottom side of the stored products. Then a comparison between products of the conventional and modified refrigerator is held using multiple parameters such as: minimum approachable temperature and temperature fluctuation during cyclic operation. While, period factor and heat recovery gained are investigated at planned power outage intervals. The 01involved PCMs types are (i.e. C-18, RT-9, cooler shock) while paring both of (RT-9 and C-18) is developed. Tests performed at different heights with the lower evaporator surface as the reference point show that RT-9 PCM achieves the maximum net energy saving ratios of 23% at dimensionless heights of H=0.25 and 25% at H=0.375.
