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.

The present disclosure relates to a method of controlling an adiabatic demagnetization apparatus. The method includes varying at least operation parameter of the adiabatic demagnetization apparatus.

A magnetic heat pump includes magnetocaloric members, an impeller, deformable members, a casing, an electric motor, and a magnetic field generator. The impeller has accommodation chambers. The deformable members face the accommodation chambers. The casing has an interior space accommodating the magnetocaloric members, the impeller, and the deformable members and allowing a heat transport medium to circulate, a first inlet, and a first outlet spaced apart from the first inlet in the circumferential direction. The magnetic field generator produces a magnetic field becoming stronger along the first direction, in a first region extending from the first inlet to the first outlet in the first direction in the interior space. The shapes of the deformable members individually change with the rotation. The volumes of the accommodation chambers individually increase and decrease with change in shape of the deformable members.
