Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 3 (Mai 2013) . - pp. 1015–1028 Titre : Proposal and validation of a model for the dynamic simulation of a solar-assisted single-stage LiBr/water absorption chiller Titre original : Proposition et validation d'un modèle pour la simulation dynamique d'un refroidisseur à absorption au LiBr / eau solaire monoétagé Type de document : texte imprimé Auteurs : G. Evola, Auteur ; N. Le Pierrès, Auteur ; F. Boudehenn, Auteur Année de publication : 2013 Article en page(s) : pp. 1015–1028 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Absorption  chiller;  Lithium  bromide;  Dynamic  performance;  Simulation;  Experimental  results Résumé : In this paper, a general mathematical model for the dynamic simulation of a single-effect LiBr/water absorption chiller is presented. The model is based on mass and energy balances applied to the internal components of the machine, and it accounts for the non-steady behaviour due to thermal and mass storage in the components. The validation of the mathematical model is performed through experimental data collected on a commercial small-capacity water-cooled unit. Due to the peculiar technology adopted in the real chiller, a special effort was made to identify the appropriate values of the main physical parameters. The validation of the model is based on the values of the water temperature at the outlet of the machine, as no measurement inside the machine was possible; anyway, a consistency analysis applied to the internal parameters is also presented. The agreement between experimental and simulated results is very good, both on a daily and on a seasonal basis.
