    摘要: A compact and highly efficient hybrid magnetic refrigerator includes a hybrid refrigerating apparatus wherein an evaporator of a vapor compression refrigeration cycle and a heat exchanger of a magnetic refrigeration cycle are thermally connected. The magnetic refrigeration cycle is provided with a magnetic refrigeration unit in which a magnetic substance dissipates and absorbs heat according to the increase and decrease of a magnetic field in order to heat and cool a refrigerant circulating in its vicinity. The heated refrigerant is cooled by the evaporator of the vapor compression refrigeration cycle and the cooled refrigerant is supplied to the heat exchanger cooling the outside air.

    摘要: A magnetic material comprising a NaZn13 type crystal structure with uniform and fine microstructure exhibiting excellent characteristics as a magnetic refrigeration material, and a method of manufacturing the magnetic refrigeration material are provided. An alloy composition for forming magnetic material of the NaZn13 type crystal structure was melted comprising 0.5 atomic percent to 1.5 atomic percent of B to molten metal. The molten metal is rapidly cooled and solidified by a forced cooling process. Then, a rapidly cooled alloy having the NaZn13 type crystal structure was obtained. In this manner, magnetic materials comprising the NaZn13 type crystal structure phase, or the NaZn13 type crystal structure phase accompanied with other phases such as α-Fe phase having very small phase regions was manufactured without requiring heat treatment for a long time. As the result, productivity of manufacturing the magnetic refrigeration material is remarkably enhanced.

    摘要: The magnetic material for magnetic refrigeration of the present invention is characterized by exhibiting, in a certain temperature region, preferably, only in part of a temperature region from 200 K to 350 K, an inflection point at which a second order differential coefficient of a magnetization curve changes from positive to negative with respect to a magnetic field, within the range of this magnetic field formed using a permanent magnet unit. This magnetic material of the present invention can generate a low temperature by using a relatively low magnetic field, by transferring the entropy between the electron spin system and the lattice system near the temperature at which an inflection point appears on the magnetization curve. Examples of the magnetic material meeting this condition are La(Fe,Si)13, (Hf,Ta)Fe2, (Ti,Sc)Fe2, and (Nb,Mo)Fe2, each containing 50 to 60 atomic % of transition metals such as Fe.
