Development and experimental results from a 1 kW prototype AMR / C. R. H. Bahl in International journal of refrigeration, Vol. 37 N° 1 (Janvier 2014) 

Public ISBD [article]  in International journal of refrigeration > Vol. 37 N° 1 (Janvier 2014) . - pp. 78-83 Titre : Development and experimental results from a 1 kW prototype AMR Titre original : Développement d'un prototype de régénérateur magnétique actif d'une puissance de 1 kW et résultats expérimentaux Type de document : texte imprimé Auteurs : C. R. H. Bahl, Auteur ; K. Engelbrecht, Auteur ; D. Eriksen, Auteur Année de publication : 2014 Article en page(s) : pp. 78-83 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Magnetic  refrigeration;  magnetocaloric  device;  active  magnetic  regenerator;  gadolinium Résumé : A novel rotary magnetic refrigeration device has been designed and constructed following the concepts recently outlined in Bahl et al. (2011). The magnet and flow system design allow for almost continuous usage of both the magnetic field and the magnetocaloric material in 24 cassettes, each containing an active magnetic regenerator (AMR) bed. The prototype design facilitates easy exchange of the 24 cassettes, allowing the testing of different material amounts and compositions. Operating with 2.8 kg of commercial grade Gd spheres a maximum no-span cooling power of 1010 W and a maximum zero load temperature span of 25.4 K have been achieved. For the purpose of actual operation, simultaneous high span and high performance is required. At a heat load of 200 W a high temperature span of 18.9 K has been obtained, dropping to a span of 13.8 K at the higher heat load value of 400 W.
