Performance evaluation of combined adsorption refrigeration cycles / Khairul Habib in International journal of refrigeration, Vol. 34 N° 1 (Janvier 2011) 

Public ISBD [article]  in International journal of refrigeration > Vol. 34 N° 1 (Janvier 2011) . - pp. 129-137 Titre : Performance evaluation of combined adsorption refrigeration cycles Titre original : Evaluation de la performance des cycles frigorifiques combinés à adsorption Type de document : texte imprimé Auteurs : Khairul Habib, Auteur ; Bidyut Baran Saha, Auteur ; Anutosh Chakraborty, Auteur Année de publication : 2011 Article en page(s) : pp. 129-137 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Adsorption  Cooling  R134a  R507  Activated  carbon-cycle Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : This paper presents the results of an investigation on the performance of combined adsorption refrigeration cycles. The novel combined cycle amalgamates the activated carbon (AC)-R507A as the bottoming cycle and AC-R134a cycle as the topping cycle and deliver refrigeration load at as low as −10 °C at the bottoming cycle. The cycle simulation is based on the experimentally confirmed adsorption isotherms, kinetics and isosteric heat of adsorption data for R134a and R507A on highly porous based activated carbon of type Maxsorb III. The optimum cooling capacity, coefficient of performance (COP) and chiller efficiency are calculated in terms of cycle time, switching time, regeneration and brine inlet temperatures. Results show that the combined adsorption cycles are feasible even when low-temperature heat source is available.
