Abstract
A magneto-caloric effect type heat pump apparatus includes a magneto-caloric element which generates heat when an external magnetic field is applied to and which absorbs heat when the external magnetic field is removed from; a magnetic field switcher which switches the applying and the removal of the external magnetic field from each other; a pump pumping a heat transport medium between a low-temperature end and a high-temperature end of the magneto-caloric element; and an auxiliary heat source device which supplies heat of a heating element to the magneto-caloric element.

A magneto-caloric effect type heat pump apparatus which supplies heat of a main heat source to a thermal load, the magneto-caloric effect type heat pump apparatus comprising:
- a magneto-caloric element which generates heat when an external magnetic field is applied to and which absorbs heat when the external magnetic field is removed from;
- a magnetic field switcher which switches the external magnetic field between the applying and the removal;
- a pump pumping heat transport medium from a low-temperature end of the magneto-caloric element toward a high-temperature end of the magneto-caloric element when the external magnetic field is applied to the magneto-caloric element, and pumping heat transport medium from the high-temperature end toward the low-temperature end when the external magnetic field is removed from the magneto-caloric element;
- and
- an auxiliary heat source device which supplies heat of a heating element to the magneto-caloric element.
