Title: Systems and methods for flow-synchronous field motion heat transfer

Abstract

An active regenerator in a magnetocaloric or an electrocaloric heat pump refrigeration system provides more efficient flow of heat. The heat exchange fluid moves synchronously with the motion of a magnetic or electric field. Only a portion of the length of the active regenerator bed is introduced to or removed from the field at one time, giving rise to a hot pulse and a cold pulse. Valves may direct the hot pulse and/or the cold pulse to supplement refrigeration.
