The electrocaloric effect, recognized for its zero greenhouse emissions, high energy efficiency, and superior power density, has been identified by the United States Department of Energy as a key technology for the next generation of zero-carbon refrigeration technologies. The objective of this project is to design and manufacture a novel prototype of a solid-state, high-efficiency, zero carbon emission electrocaloric refrigeration system for window applications. This system will be based on the physical principles of the electrocaloric effect, involving the design and fabrication of a polymer-based electrocaloric refrigeration composite material with high electrical-to-thermal energy conversion efficiency. Additionally, the project aims to investigate the relationship between structure and performance across sub-nanoscale, nanoscale, and microscale dimensions within the composite material, optimize the fabrication process for the polymer electrocaloric refrigeration films, and enhance the efficiency of the electrocaloric refrigeration cycle. The ultimate goal is to fabricate a highly efficient film electrocaloric refrigeration component and design a flexible film window air conditioning prototype that operates without external mechanical drives and possesses an exceptionally high power-to-weight ratio, thereby advancing the practical application of electrocaloric refrigeration technology.
