Development of room temperature magnetic refrigerator in Japan.
Author(s) : HIRANO N., NAGAYA S., OKAMURA T., et al.
Summary
A highly effective magnetic refrigeration system using a permanent magnet with a rotational mechanism has been developed as a national project in Japan. To help reduce the effects of global warming, the authors have developed a refrigerating aggregate that is principally different, in order to serve as a substitute for conventional gas freezers, using fluorocarbon/fluorocarbon gas. In addition, in order to reduce energy consumption from prolonged operating times, they have developed energy-conserving electric equipment that incorporates refrigerating aggregates such as air conditioners. Altering the magnetic field around certain types of magnetic materials changes their temperature (magneto-caloric effect). The authors have conducted R&D to convert magnetic refrigeration technology, which uses this effect and is a highly-efficient, energy conserving/environment-friendly technology, into practical application. In this paper, recent development results about room temperature magnetic refrigeration technologies as a national project in Japan are presented.
