Experimental analysis of a reciprocating magnetic refrigeration prototype / J. Romero Gómez in International journal of refrigeration, Vol. 36 N° 4 (Juin 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 4 (Juin 2013) . - pp. 1388–1398 Titre : Experimental analysis of a reciprocating magnetic refrigeration prototype Titre original : Analyse expérimentale d'un prototype de système frigorifique magnétique alternatif Type de document : texte imprimé Auteurs : J. Romero Gómez, Auteur ; R. Ferreiro Garcia, Auteur ; J. Carbia Carril, Auteur Année de publication : 2013 Article en page(s) : pp. 1388–1398 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Magnetic  refrigeration;  Design;  Experimentation;  Gadolinium;  Temperature Résumé : In this paper, a reciprocating magnetic refrigeration prototype (MR) with a novel and simple design is presented using permanent magnets for operation at room temperature. The design, installation, operation and preliminary results are reported. The experimental machine is characterised by the implementation of a force compensation system applied on the displacement of the active magnetic regenerator (AMR). Preliminary calculations based on experimental measurements show that approximately 90% of the displacement force is reduced with the proposed design. Using a total of 180 g of Gd as magnetocaloric refrigerant in a magnetic field of 1 T, the device achieved a maximum temperature span under no thermal load of 3.5 K, rendering a cooling power of about 3 W under a span approaching 0 K.
