Magnetic refrigerators use magnetic regeneration as an operating principle. A regenerator is a thermal device that transfers heat into a heat transfer medium during one stage of a regenerative cycle, and then transfers heat out of that heat transfer medium during an opposite phase of the regenerative cycle. Magnetic refrigeration uses magnetocaloric materials as a working element. Conventional refrigeration technologies use gas compression and expansion with chlorofluorocarbons (CFC's). A magnetic regenerator applies a time-varying magnetic field and reciprocating flow of a heat transfer medium to an elongated container of magnetocaloric materials. Magnetocaloric materials have the property that their temperature changes when a magnetic field is applied. They will be warm when magnetized and cool when demagnetized when they're near a transition from a ferromagnetic state to a paramagnetic state. In this way, active magnetic regeneration may be used in a magnetic refrigerator, to provide cooling, or in a heat pump, to provide heating. Magnetic refrigeration doesn't make use of volatile fluids, such as chlorofluorocarbons, that may harm the environment. Magnetic refrigeration is more energy efficient than conventional refrigeration technologies.
