Abstract: The refrigerant is a key issue to achieve energy saving and system performance improvement in refrigerators. The technology development of zeotropic mixture in refrigerators was summarized including Linde-Hampson refrigeration cycle, auto-cascade refrigeration cycle to accomplish -40°C and lower temperature. On the other hand, the application of zeotropic mixture in dual-temperature refrigerators was also investigated. In addition, this paper reviewed the choose of mixture component and composition optimization, two-phase flow and heat transfer, system configuration, composition shift and changing concentration attribute. These studies with unique features eventually extend the research methods regarding zeotropic mixture in refrigeration field. Based on the future trend of refrigerant, the application of hydrocarbons in refrigerators was described and the key development trends were proposed. This review aims to promote the use of zeotropic mixture refrigerant in refrigerators, which can bring technology innovation and industrial upgrading of refrigerator industry.
