Experimental investigation of the temperatures and performance of a commercial ice-storage tank / A. López-Navarro 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.1310–1318 Titre : Experimental investigation of the temperatures and performance of a commercial ice-storage tank Titre original : Etude expérimentale sur les températures et la performance d'un bac à accumulation de glace commercial Type de document : texte imprimé Auteurs : A. López-Navarro, Auteur ; J. Biosca-Taronger, Auteur ; B. Torregrosa-Jaime, Auteur Année de publication : 2013 Article en page(s) : pp.1310–1318 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Thermal  storage;  Experimental  installation;  Ice  formation;  Energy  consumption Résumé : This paper presents the results of an experimental installation with an internal melt-ice-on-coil tank which has a total capacity of 172 kWh. The aim of this work is to analyse the freezing process in a tank with counter-current spiral-shaped coils immersed in around 1855l water. An experimental campaign has been performed with different inlet temperatures and mass flow rates of the heat transfer fluid. This study analyses (i) the chiller performance, (ii) the ice-formation process and (iii) the energy consumption of the installation. Supply temperatures between −2.5 °C and −5.2 °C have been sufficient to charge the tank without using any nucleating agents. The lowest energy consumption has been achieved for the fastest charging tests.

Sizing of a reversible magnetic heat pump for the automotive industry / B. Torregrosa-Jaime 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. 156–164 Titre : Sizing of a reversible magnetic heat pump for the automotive industry Titre original : Dimensionnement d'une pompe à chaleur magnétique réversible pour l'industrie automobile Type de document : texte imprimé Auteurs : B. Torregrosa-Jaime, Auteur ; J. M. Corberán, Auteur ; C. Vasile, Auteur Année de publication : 2014 Article en page(s) : pp. 156–164 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Magnetic  refrigerator;  heat  pump;  automobile;  air  conditioning;  modelling Résumé : This paper focuses on the design of an innovative air-conditioning system, namely a magnetocaloric air-conditioner for an electric minibus. An integrated design of the complete system is necessary, as the hot and cold side of the regenerator will work under dynamic conditions which depend on the instantaneous thermal load in the cabin. In order to assist the design of the system, a dynamic model has been developed for the cabin, the hydraulic loops and heat exchangers, and the magnetocaloric unit. This paper presents (i) a description of the dynamic models, (ii) an analysis of the operating conditions of the magnetocaloric unit and (iii) a discussion on the design of the magnetocaloric air-conditioner. The results show that the electric minibus requests 1.60 kW of cooling power over a span of 37 K in cooling mode, and 3.39 kW of heating power over a span of 40 K.
