摘要:
In a magnetic heat pump system, in which heat transport medium is heated or cooled by magnetocaloric effect material accommodated in a magnetic heat pump device. A material having a coefficient of thermal conductivity, which is higher than that of the heat transport medium, or a material having a specific heat or a volume specific heat, which is higher than that of the heat transport medium, is mixed in the heat transport medium. A coefficient of thermal conductivity of the heat transport medium is thereby increased so as to increase heating and/or cooling performance of the magnetic heat pump system.

摘要:
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 thermo-magnetic cycle apparatus includes: a magnetic element having a Curie temperature distribution in a distribution direction. A magnetic-field supplier supplies an external magnetic field to the magnetic element. A pump pumps heat transport medium to flow forward and backward in the distribution direction. The heat transport medium transports heat of the magnetic element. A shift device causes a position of a high temperature end and/or a low temperature end of the magnetic element to move.

A thermo-magnetic engine apparatus includes a magnetic element having a high temperature end to which hot energy is supplied and a low temperature end to which cold energy is supplied, a magnetic-field applier device, and a power source device. Curie temperature of the magnetic element is set between a temperature of the high temperature end and a temperature of the low temperature end. The power source device gains a magnetic power generated between the magnetic element and the magnetic-field applier device as kinetic energy.

摘要:
A magnetic heat pump cycle has a first to a fourth steps, which are repeatedly carried out. In the first step, a movement of heat medium is stopped by a pressure valve and a pressure accumulating tank and a magnetic field is applied by a magnetic-field control unit to a magnetic working material. In the second step, the pressure valve is opened so that the heat medium flows in a working chamber from a second axial end to a first axial end, and the magnetic field is increased depending on a moving speed of the heat medium. In the third step, the movement of the heat medium is stopped and the magnetic field is decreased. In the fourth step, the heat medium is moved in a reversed direction and the magnetic field is decreased depending on the moving speed of the heat medium.

A thermo-magnetic cycle apparatus includes: a magnetic element having a Curie temperature distribution in a predetermined distribution direction; a magnetic-field supplier which supplies an external magnetic field to the magnetic element; a pump pumping heat transport medium to flow frontward and backward in the predetermined distribution direction, the heat transport medium transporting heat of the magnetic element; and a shift device which causes a position of a high temperature end and/or a low temperature end of the magnetic element to move.
