摘要： A heat transfer system cycles between a first mode where a heat transfer fluid is directed to a first electrocaloric module and from the first electrocaloric module to a heat exchanger to a second electrocaloric module while one of the first and second electrocaloric modules is energized, and a second mode where the heat transfer fluid is directed to the second electrocaloric module and from the second electrocaloric module to the heat exchanger to the first electrocaloric module, while the other of the first and second electrocaloric modules is energized. The modes are repeatedly cycled in alternating order directing the heat transfer fluid to cause a temperature gradient in each of the first and second electrocaloric modules, and heat is rejected to the fluid from the heat exchanger or is absorbed by the heat exchanger from the fluid.

摘要： The invention provides a method for cooling fluid having the steps of supplying a fluid at a first temperature T1, raising the temperature of the fluid to a second temperature T2 through contact with an electric field, contacting the fluid with a heat exchanger to decrease its temperature to a third temperature T3, removing the electric field to decrease the temperature of the fluid to a fourth temperature T4, and applying a heat load to the fluid to increase the temperature of the fluid to T1. Also provided is a system for cooling fluid having a closed loop having a first region subject to an electric field, a second region in contact with a heat exchanger, a third region remote from the electric field, and a fourth region contacting a heat load.

摘要： An electrocaloric with active regeneration includes first and second electrocaloric capacitors proximate one another enabling heat transfer there between. In the system, complementary first and second electric fields are applied to their respective electrocaloric capacitors such that when the electric fields are applied the temperature of the first electrocaloric capacitor increases while the temperature of the second electrocaloric capacitor decreases or vice-versa. Shifting of one or both of the electrocaloric capacitors relative to one another assists in heat transfer between the two and may additionally transfer heat from an object to be cooled, which is connected to the first electrocaloric capacitor, to a heat sink, which is connected to a second electrocaloric capacitor.
