Public ISBD [article]  inInternational journal of refrigeration > Vol. 36 N° 3 (Mai 2013) . - pp. 828–841 Titre : Four E analysis and multi-objective optimization of an ice thermal energy storage for air-conditioning applications : Analyse tenant compte des aspects énergétiques, exergétiques, économiques et environnementaux et optimisation à objectifs multiples Titre original : Système à accumulation thermique de glace pour les applications en conditionnement d'air Type de document : texte imprimé Auteurs : Sepehr Sanaye, Auteur ; Ali Shirazi, Auteur Année de publication : 2013 Article en page(s) : pp. 828–841 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Ice thermal storage-system  Energy  Exergy  Economy  Environment  Multi-objective optimization Résumé : One method to reduce the peak electrical demand of air-conditioning (A/C) systems is incorporating an ice thermal energy storage (ITES) with the A/C system. In this paper, an ITES system was modeled for A/C applications and analyzed from energy, exergy, economic, and environmental aspects (4E analysis). Applying the genetic algorithm optimization technique, multi-objective optimization of the system was performed and the optimum values of system design parameters were obtained. The exergy efficiency and total cost rate were considered as objective functions. The performance of modeled ITES system was also compared with a conventional system. The results indicated that electricity consumption in ITES system was 10.9% lower than that of the conventional one. Furthermore, 0.659 × 106 kg of CO2 was prevented from emitting into the atmosphere in comparison with the conventional system. The extra capital cost associated with using ITES system was paid back with savings in electricity consumption in 3.39 years.
