The energy management system includes: a fuel cell configured to supply energy used in a facility; a first hydrogen supply unit configured to supply hydrogen to the fuel cell by causing a power generation apparatus that uses renewable energy to perform water electrolysis; a second hydrogen supply unit configured to supply hydrogen to the fuel cell by reforming natural gas supplied via a pipeline; and a control unit configured to determine a ratio between hydrogen supplied from the first hydrogen supply unit to the fuel cell and hydrogen supplied from the second hydrogen supply unit to the fuel cell. The control unit determines the ratio in accordance with a percentage of heat energy and energy other than the heat energy with respect to the energy used in the facility.

A magnetic heat pump system which arranges permanent magnets at the two sides of a magnetocalorific effect material to thereby strengthen the magnetic field to improve the cooling and heating ability, which magnetic heat pump system uses first and second magnets which move inside and outside of the containers in the state facing each other to change a magnitude of a magnetic field which is applied to a plurality of containers in which a magnetocalorific effect material is stored so as to change a temperature of a heat transport medium which is made to flow through the containers by a reciprocating pump, the intensity of the magnetic field which is applied to the magnetocalorific effect material in the containers being increased to enlarge the change of temperature of the heat transport medium which is discharged from the magnetic heat pump and improve the cooling and heating efficiency.

Magnetic heat pump system and air-conditioning system using that system

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.

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.
