Summary

This article is the Spanish translation of an article presented at the IIR conference in Des Moines, USA (see the Bulletin of the IIR, reference 2009-1581). 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 effort should therefore be invested in improving the magnet design. In this paper the authors analyze the different efficiency and usability of permanent magnets and electromagnets/superconducting magnets. They then present an overview of different published magnet designs used in magnetic refrigeration applications. These designs are analyzed based on the generated magnetic flux density and the amount of magnetic material used. This is done by characterizing each design by a magnet design efficiency parameter. The analyses of the different published permanent magnet designs allows us to present recommendations for improving existing magnet designs as well as discussing the features of the best magnet design for magnetic refrigeration.
