On the parameters of performance of combined refrigeration and power plants / José Alexandre Matelli in International journal of refrigeration, Vol. 36 N° 8 (Décembre 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 8 (Décembre 2013) . - pp. 2169-2175 Titre : On the parameters of performance of combined refrigeration and power plants Titre original : Sur les paramètres de performance de centrales de cogénération de froid et d'électricité Type de document : texte imprimé Auteurs : José Alexandre Matelli, Auteur ; Edson Bazzo, Auteur Année de publication : 2014 Article en page(s) : pp. 2169-2175 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Cogeneration;  efficiency;  primary  energy Résumé : Combined Refrigeration and Power (CRP) plants generate power and refrigerate a thermal load simultaneously from the same fuel. The overall efficiency is a parameter based on the first law generally used to quantify the fuel saving, in the sense that a plant that has greater overall efficiency saves more fuel than others to generate the same useful energy. However, the literature shows that the overall efficiency and other parameters of performance are defined in several different ways. This heterogeneity is not desirable when considering a coherent and universally accepted parameter of performance based on the first law. In this work, some parameters found in the literature are critically analyzed in order to indicate the most proper one. The indicated parameter is then formally analyzed in order to verify its mathematical consistency. The primary energy rate is considered the most well-suited parameter based on the first law to characterize the performance of a CRP plant.
