Thermal investigations of an experimental active magnetic regenerative refrigerator operating near room temperature / Y. Chiba 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. 36-42 Titre : Thermal investigations of an experimental active magnetic regenerative refrigerator operating near room temperature Titre original : Etudes thermiques d'un réfrigérateur magnétique actif expérimental fonctionnant à température ambiante Type de document : texte imprimé Auteurs : Y. Chiba, Auteur ; Smaili, Arezki, Auteur ; C. Mahmed, Auteur Année de publication : 2014 Article en page(s) : pp. 36-42 Note générale : refrigeration Langues : Anglais (eng) Mots-clés : Active  magnetic  regenerator;  numerical  simulation;  magnetocaloric  effect;  thermal  analysis Résumé : In this paper, numerical and experimental investigations on a magnetic refrigeration device based upon the active magnetic regeneration (AMR) cycle operating near room temperature are presented. A numerical 1D model based on the transient energy equations is proposed for modelling the heat exchange between the magnetocaloric material and the carrier fluid in the regenerator bed. The validity of 1D AMR-numerical model is investigated through the recently developed magnetic cooling demonstrator by Clean Cooling Systems SA (CCS) at the University of Applied Sciences of western Switzerland (HES−SO). The obtained results including the temperature span, the coefficient of performance and the cooling power are presented and discussed. In general, good agreements have been noted between the experimental and numerical results.
