Abstract

A heat pump system having magneto caloric material positioned in a continuously rotating regenerator is provided. The magneto caloric material is staged so that as the regenerator is rotated, a portion of the material is cycled in and out of a magnetic field in a continuous manner. A heat transfer fluid is circulated through the magneto caloric material simultaneously along at least two paths to provide for the transfer of heat both to and from the material in a cyclic manner. The magneto caloric material may include zones having different temperature ranges of responsiveness to the magnetic field. An appliance using a heat pump system based on magneto caloric material is also provided.

Description

FIELD OF THE INVENTION[0001]The subject matter of the present disclosure relates generally to a heat pump system that uses magneto caloric materials to exchange heat with a circulating heat transfer fluid.BACKGROUND OF THE INVENTION[0002]Conventional refrigeration technology typically utilizes a heat pump that relies on compression and expansion of a fluid refrigerant to receive and reject heat in a cyclic manner so as to effect a desired temperature change or i.e. transfer heat energy from one location to another. This cycle can be used to provide e.g., for the receiving of heat from a refrigeration compartment and the rejecting of such heat to the environment or a location that is external to the compartment. Other applications include air conditioning of residential or commercial structures. A variety of different fluid refrigerants have been developed that can be used with the heat pump in such systems.[0003]While improvements have been made to such heat pump systems that rely o...
