Magnetic refrigeration device and magnetic refrigeration system

A magnetic refrigeration system comprising

• a plurality of magnetic refrigeration devices arranged substantially along a circle and each including:
• a stationary members arranged in parallel with each other, with gaps defined between adjacent ones of the stationary members, each of the stationary members being formed of one of a magnetic body having a magnetocaloric effect, and a solid heat accumulation member having a heat accumulation effect, the adjacent ones of the stationary members opposing each other;
• and
• a plurality of movable members arranged in parallel with each other, and permitted to be brought into contact with the adjacent stationary members within the respective gaps and thermally connected to the adjacent stationary members, each of the movable members being formed of the other of the magnetic body and the solid heat accumulation member;
• at least one magnetic field apply unit provided along the circle over or below the plurality of magnetic refrigeration devices and configured to start and stop application of a magnetic field to the magnetic body;
• and
• a moving mechanism configured to selectively bring the movable members to the corresponding stationary members in synchronism with the start and stop of the application of the magnetic field of the magnetic field apply unit.
