Abstract

Disclosed is a heat transfer system with a module that includes a peripheral frame (10) and an electrocaloric element (46) disposed in an opening in the peripheral frame. The electrocaloric element includes an electrocaloric film (46), a first electrode (48) on a first side of the electrocaloric film, and a second electrode (50) on a second side of the electrocaloric film. First and second electrically conductive elements (24, 25) are disposed adjacent to first and second surfaces of the peripheral frame, and provide an electrical connection to the first and second electrodes.
