Review on research and application of phase change materials in cold storage refrigerator

Abstract

Phase change material energy storage technology can effectively improve energy efficiency and alleviate environmental deterioration. Therefore, it is widely used in cold chain equipment such as cold storage refrigerators. In this paper, the low-temperature phase change materials (Tm<10°C) for refrigerators were reviewed, and the advantages, disadvantages and research of each phase change material were analyzed and compared. In addition, this paper reviews the effect of microcapsule technology on the properties of low-temperature phase change materials, and introduces the application of cold storage refrigerator in food and pharmaceutical cold chain. Finally, the research direction of cold storage refrigerator is prospected and the key problems to be solved are put forward.
