Abstract
A magnetic structure has a magnetocaloric material the temperature of which changes with application or removal of a magnetic field, and a high thermal conduction member which is in contact with the magnetocaloric material and has higher thermal conductivity than the magnetocaloric material. Further, this magnetic air-conditioning and heating device is provided with multiple of the aforementioned magnetic structures, a thermal switch which is arranged between magnetic structures and transmits or insulates heat, and a magnetic field varying unit which applies or removes a magnetic field to each of the magnetic structures. By providing in the magnetic structures a high thermal conduction member with higher thermal conductivity than the magnetocaloric material, some or all of the heat generated in the magnetocaloric material can be quickly conducted in the magnetic bodies.
