R. Bjørk, Auteur ; A. Smith, Auteur ; C. R. H. Bahl, Auteur |An expression is determined for the mass of the magnet and magnetocaloric material needed for a magnetic refrigerator and these are determined using numerical modeling for both parallel plate and packed sphere bed regenerators as function of tem[...]

R. Bjørk, Auteur ; C. R. H. Bahl, Auteur ; A. Smith, Auteur |One of the key issues in magnetic refrigeration is generating the magnetic field that the magnetocaloric material must be subjected to. The magnet constitutes a major part of the expense of a complete magnetic refrigeration system and a large ef[...]
