Abstract: A heat pump is provided that uses multiple stages of MCMs to cause heat transfer between a heat receiving end and a heat transmitting end. Thermal blocks are placed along the direction of heat transfer at locations in the heat pump that preclude the transfer of heat in a direction from the heat transmitting end towards the heat receiving end. The heat pump can be, for example, part of a refrigeration loop or can be connected directly with the object for which heating or cooling is desired. An appliance incorporating such a heat pump is also provided.

Abstract: A magnetic device is provided for a magneto caloric heat pump regenerator. Magnets are arranged within two magnetic flux circuits in a manner than that provides at least four fields of increased magnetic flux density. The regenerator can be used to move working units of magneto caloric material through the fields of increase magnetic flux to provide for heating and cooling as part of heat pump cycle. The orientation of the magnets provides concentrated fields of magnetic flux to induce the magneto caloric effect while optimizing the size of the magnets required to create the fields.

Abstract: A magnetocaloric driving device is disclosed herein. The driving device comprises a magnet, an effective amount of a magnetocaloric material, and a counterpoise mechanism. The driving device generates useful mechanical energy by alternately cooling and heating the magnetocaloric material using an ambient heat sink proximate to a heat source. Useful heat sources include hot production fluids, such as hot water produced from a geothermal well. Useful heat sinks include cold production fluids, and cold ambient environments.

Abstract: A heat pump system is provided that uses MCM to provide for heating or cooling. The heat pump can include one or more stages of MCM, each stage having an original peak Curie temperature. In the event the magneto caloric response of one or more stages of MCM degrades, the present invention provides for operating the heat pump system so that one or more stages of MCM are held at a different temperature from the original peak Curie temperature so as to restore the MCM to its original peak Curie temperature or to within a certain interval thereof. The present invention can be used with e.g., an appliance, air-conditioning systems (heating or cooling), or other devices using such a heat pump system as well.

Abstract: A heat pump system is provided that uses MCM for heating or cooling. A magnetic field of decreasing flux intensity is used to decrease power consumption and reduce e.g., the size of one or more magnetic devices associated with creating the magnetic field. In one exemplary embodiment, the heat pump is constructed from a continuously rotating regenerator where MCM is cycled in and out of a magnetic field in a continuous manner and a heat transfer fluid is circulated therethrough to provide for heat transfer in a cyclic manner. The magneto caloric material may include stages having different Curie temperature ranges. An appliance using such a heat pump system is also provided. The heat pump may also be used in other applications for heating, cooling, or both.
