Abstract: An electrocaloric module includes an electrocaloric element that includes an electrocaloric film, a first electrode on a first surface of the electrocaloric film, and a second electrode on a second surface of the electrocaloric film. A support is attached along an edge portion of the electrocaloric film, leaving a central portion of the electrocaloric film unsupported film. At least one of the first and second electrodes includes a patterned disposition of conductive material on the film surface. The electrocaloric module also includes a first thermal connection configured to connect to a first thermal flow path between the electrocaloric element and a heat sink, a second thermal connection configured to connect to a second thermal flow path between the electrocaloric element and a heat source, and a power connection connected to the first and second electrodes and configured to connect to a power source.

Abstract: 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.

Abstract: Embodiments are directed to a heat pump element comprising: a thin-film polymer or ceramic material within a range of 0.1 microns-100 microns thickness, and electrodes coupled to both sides of the thin-film material to form an electroded active thin-film material, wherein the thin-film material is separated by, and in intimate contact with, a heat transfer fluid in channels within a range of 10 microns-10 millimeters thickness, in which the fluid is capable of being translated back and forth through the element by an imposed pressure field.

Abstract: A Stirling refrigeration system is disclosed that comprises a Stirling unit having a hot end and a cold end. In addition, the Stirling refrigeration system includes a hot heat exchanger fluidically coupled to the hot end and configured to release the heat form the hot end, wherein the hot heat exchanger and the hot end define a hot circuit for a first refrigerant to flow therein. Further, the Stirling refrigeration system includes a cold heat exchanger fluidically coupled to the cold end and configured to remove the heat from the cold end, wherein the cold heat exchanger and the cold end define a cold circuit for a second refrigerant to flow therein. One of the first refrigerant and the second refrigerant comprises a two-phase low GWP refrigerant.

Abstract: A method of realizing a ferroic response is provided. The method includes applying a positive or negative conjugate field, which is of a first polarity, to a ferroic material to obtain a substantially minimized entropy of the ferroic material (301) and applying a slightly negative or a slightly positive conjugate field, which is of a second polarity opposite the first polarity, to the ferroic material to obtain a substantially maximized entropy of the ferroic material (302).
