30 years of near room temperature magnetic cooling.

Author(s) : GSCHNEIDNER K. A. Jr, PECHARSKY V. K.

Summary

The seminal study by Brown in 1976 showed that it was possible to use the magnetocaloric effect to produce a substantial cooling effect near room temperature. About 15 years later Green et al. built a device which actually cooled a load other than the magnetocaloric material itself and the heat exchange fluid. The major breakthrough, however, occurred in 1997 when the Ames Laboratory/Astronautics proof-of-principle refrigerator showed that magnetic refrigeration was competitive with conventional gas compression cooling. Since then over 20 magnetic cooling machines have been built and tested throughout the world. The current status of near room temperature cooling is reviewed, including the major problems facing commercialization and potential solutions thereof. The future outlook for this revolutionary technology is discussed.
