  • Systems and methods for flow-synchronous field motion heat transfer
    Patent number: 10352595
    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.
    Type: Grant
    Filed: August 14, 2017
    Date of Patent: July 16, 2019

  • Flow-synchronous field motion refrigeration
    Patent number: 9739510
    Abstract: An improved method to manage the flow of heat in an active regenerator in a magnetocaloric or an electrocaloric heat-pump refrigeration system, in which 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, and the heat exchange fluid flows from the cold side toward the hot side while the magnetic or electric field moves along the active regenerator bed.
