Electrocaloric Refrigeration near Room Temperature

Abstract

in this study, for a room temperature electrocaloric cooling device, a decoupled multiphysics numerical model (electric, heat transfer, and fluid flow) is developed using COMSOL multphysics, as a design tool, user defined function are incorporated into the software (COMSOL) in order to take into account the ECE. Ferroelectric materials is the best solutions for EC cooling. Material with a large ECE room temperature and a broad working temperature range are getting closer to practical application. We numerically calculated the effects of parameter in EC refrigeration.
