Regenerative characteristics of electrocaloric Stirling or Ericsson refrigeration cycles
Energy Conversion and Management 43(2002)2319-2327,-0001,():
The thermodynamic properties of the dielectric materials are analyzed in detail, based on the Curie law, Curie-Weiss law andother relations betweenthe electrical polarization and the electric fieldstren gth. It is proven that the specific heat at constant electrical polarization is only a function of temperature, while the specific heat at constant electric field strength is dependent on the electric field strength and temperature. Moreover, the regenerative characteristics of the electrocaloric Stirling andEricsso n refrigeration cycles are discussed. Some important conclusions are obtained.
