  • refrigerators have also been proposed which use, instead of the compressor, a magnetocaloric device through which the refrigerant flows.
  • Such devices utilize the magnetocaloric effect in which a body of magnetocalorically active material heats up when exposed to a magnetic field and cools when the magnetic field is removed.
  • Refrigerators with this operating principle are disclosed, for example, in DE 10 2006 046 041 A1 and US Pat. No. 7,536,866 B2.
  • the magnetocalorically active body is alternately magnetized and demagnetized by, for example, rotating a disk-shaped body into and out of a magnetic field or pushing a piston-shaped body into and out of a magnetic field.

If the body is then removed from the magnetic field, its order state decreases again and it reaches a lower temperature than at the beginning of the cycle. The body can thus absorb heat from a medium to cool it.
