    Abstract
  • Electric card refrigeration technology is a new type of solid-state refrigeration technology that utilizes the entropy change of electrocaloric materials during the process of charging and discharging to achieve a refrigeration cycle. It has the characteristics of high energy efficiency, light weight, and no refrigerant leakage, so that it has great application prospects in fields such as aerospace refrigerators and space wearable devices. Until now, space thermoelectric cooling technology has many problems such as high-power consumption and low Coefficient of Performance (COP), which limit its application in future aerospace engineering. This article reviews and analyzes the material properties, cold and hot separation methods, and electrocaloric refrigeration devices. It introduces the research progress in the electrocaloric composition, morphology, preparation process, feasibility, and stability, summarizes the electrocaloric refrigeration principle, as well as cold and hot separation methods of active and passive ways, and summarizes the working principles of reciprocating single-stage and reciprocating cascade electrocaloric refrigeration devices. Finally, the future development direction of electrocaloric cooling technology in the field of space science was discussed.
