More Information
Summary:A magnetic heat pump device (1) is provided with a magnetic working substance (13) having a magnetocaloric effect, magnetic working bodies (11A, 11B) in which a heat transfer medium is circulated, permanent magnets (6) changing the size of a magnetic field to be applied to the magnetic working substance, and a displacer (8) causing the heat transfer medium to reciprocate between a high-temperature end (14) and a low-temperature end (16) of the magnetic working body. The displacer (8) moves the heat transfer medium to the high-temperature end side from the low-temperature end side of the magnetic working body before the permanent magnets (6) increase the size of the magnetic field to be applied to the magnetic working substance. An improvement of efficiency is achieved by improving the timing of changing the size of the magnetic field to be applied to the magnetic working substance and the reciprocating movement of the heat transfer medium.
