Abstract: A magnetic refrigeration system includes a plurality of heat transporters, a magnetic field application unit, and a drive mechanism. Each heat transporter is switched between a heat generating and heat absorbing states in response to magnetic field application and cancellation of the magnetic field application. The heat transporters are arranged between low and high temperature side heat exchangers. The magnetic field application unit applies a magnetic field to the heat transporters so that a heat transporter to which a magnetic field is applied and a heat transporter to which a magnetic field is not applied are alternately arranged. The drive mechanism periodically moves at least the plurality of heat transporters so that a heat transporter to which the magnetic field is applied is periodically switched and so that a state of thermal contact is periodically switched. An end portion of at least one heat transporter is a heat transfer accelerator.

Abstract: A magneto-caloric-effect element has a plurality of element units. The element units have lengths, respectively. The element units have different Curie temperatures, respectively. The element units demonstrate magneto-caloric effects. Two adjoining performance distribution crosses at a cross temperature. A temperature in the rated operational status between two adjoining element units is called a boundary temperature. The lengths and/or Curie temperatures are set so that the boundary temperatures and the cross temperatures coincide each other. Thereby, a plurality of element units can function at high effectiveness in the rated operational status.
