Public ISBD [article]  inInternational journal of refrigeration > Vol. 37 N° 1 (Janvier 2014) . - pp. 16-27 Titre : Electrocaloric vs. magnetocaloric energy conversion Titre original : Comparaisons des conversions d'énergie électrocalorique et magnétocalorique Type de document : texte imprimé Auteurs : M. Ožbolt, Auteur ; A. Kitanovski, Auteur ; Jaka Tušek, Auteur Année de publication : 2014 Article en page(s) : pp. 16-27 Note générale : refrigeration Langues : Anglais (eng) Mots-clés : Electrocaloric effect  magnetocaloric magnetic refrigeration  energy conversion  refrigeration Résumé : Currently, one of the most interesting alternatives to conventional compressor refrigeration is magnetic refrigeration. However, despite its great potential, some important obstacles, relating mostly to the relatively low power density and the related high costs, must be overcome. Another alternative, which also shows great potential, is electrocaloric refrigeration. Until recently, electrocaloric materials were not so common; however, a number of different electrocaloric materials exist today. Like magnetocalorics, these can be used in the form of a regenerator in order to increase the temperature span. Based on a previously developed numerical model, we have made a comparison between electrocaloric and magnetocaloric regenerators. The results suggest that electrocaloric energy conversion represents a serious alternative, not only to compressor-based technologies, but also to magnetocalorics.
