Abstract
A heat pump system is provided that uses MCM to provide for heating or cooling. 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. A heat transfer fluid is circulated therethrough to provide for heat transfer in a cyclic manner. The MCM may include stages having different Curie temperature ranges. A field of varying magnetic flux may be used. The rotating regenerator can be equipped with one or more gaskets to improve fluid seals between the rotating regenerator and stationary parts. 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.
