Abstract

Magnetic refrigeration is an innovative, revolutionary, efficient and environmentally friendly cooling technology which is on the threshold of commercialization. The essential components of magnetic refrigeration system are the magnetic field generator and the magnetocaloric material. The two main goals of this paper are to design and to optimize a permanent magnet magnetic refrigeration machine for power cooling generation, where an initial configuration is studied and based on this study two other configurations are presented. Both electromagnetic and thermal studies are explored. The electromagnetic design part has been accomplished by using the finite elements method and the thermal design part has been achieved using the finite difference method. ⁵⁷
