    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: A heat transfer system is disclosed that includes an electrocaloric element including an electrocaloric material and electrodes arranged to impart an electric field to the electrocaloric material. A first thermal flow path is disposed between the electrocaloric material and a heat sink. A second thermal flow path is disposed between the electrocaloric material and a heat source. An electric power source is in operative electrical communication with the electrodes. The system also includes an arc suppression circuit in series with the electrocaloric element. The arc suppression circuit includes an interruptible electrical connection configured to interrupt the electrical connection in response to detection of an arc between the electrodes, and a series shunt connection in parallel with the interruptible electrical connection, with the series shunt connection including a series shunt load.

    Abstract: A building heating or cooling system is disclosed that includes an air handling system having an air delivery flow path in fluid communication with a conditioned space in the building. The building heating or cooling system also includes an electrocaloric heating or cooling system that includes first and second electrocaloric modules. A first inlet receives air from the conditioned space or the air delivery flow path and directs it through the first or second electrocaloric module to a first outlet to the conditioned space or the air delivery flow path, and a second inlet that receives air from the conditioned space or the air delivery flow path and directs it through the first or second electrocaloric module to a second outlet to outside the conditioned space.

    Abstract: A heat transfer system includes first (62) and second (64) electrocaloric module with aligned first and second sides. First and second prime movers (80,82) are arranged to direct a working fluid in opposite directions along flow paths through the electrocaloric modules. A rotary fluid control device (92,98) including a plurality of openings (94,96,100,102) is disposed around the electrocaloric modules, and is configured to rotate between positions relative to the modules. In a first position, the first module is in operative fluid communication through the openings with the first prime mover, and the second module is in operative fluid communication through the openings with the second prime mover. In a second position, the first module is in operative fluid communication through the openings with the second prime mover, and the second module is in operative fluid communication through the openings with the first prime mover.
