Freezer cooler (CF) is one of the cooling equipment for the storage needs of frozen food at low temperatures. CF is an indispensable tool for storing food and drinks to be durable. So, it is safe for consumption. Ice cream products, for example, are susceptible to temperature variations and are easily damaged during storage. Temperature fluctuations can cause dramatic adverse effects on the quality of frozen food, ice re-crystallization temperature in ice cream, and this can create substantial economic losses, and degrade the quality of frozen food. Maintaining a stable temperature in frozen food storage is very important. Current CF cooling technology consumes large amounts of electricity. It is essential to develop research on CF cooling engines that are energy efficient and environmentally friendly. Current technology makes it possible to add PCM to the walls of the cooling machine. During the phase change process, the temperature remains constant, and a large amount of energy can be stored or released. Refrigeration technology testing with PCM integrated on the evaporator has been carried out in this study and can reduce energy consumption by 4 percentage, increase COP by 6 percentage.
