Public ISBD [article]  in International journal of refrigeration > Vol. 35 N° 3 (Mai 2012) . - pp. 499–505 Titre : Accurate adsorption isotherms of R134a onto activated carbons for cooling and freezing applications Titre original : Isothermes d'adsorption précises pour le R134a sur du charbon actif dans les applications de refroidissement et de congélation Type de document : texte imprimé Auteurs : Bidyut Baran Saha, Auteur ; Ibrahim I. El-Sharkawy, Auteur ; Roger Thorpe, Auteur Année de publication : 2012 Article en page(s) : pp. 499–505 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Activated  carbon  Adsorption  isotherm  Cooling  R134a Résumé : The objective of this article is to improve the performance of thermally powered adsorption/cooling systems by selecting a new adsorbent/refrigerant pair. Adsorption equilibrium data of R134a onto granular activated carbon (AC) and Unitika activated carbon fiber (ACF) of type (A-20) have been measured experimentally using Rubotherm ISOSORP 2000 within evaporation temperatures range between −20 and 40 °C and adsorption temperatures range from 30 to 80 °C. Experimental data have been correlated using various popular isotherm models. The isosteric heat of adsorption of the assorted adsorbent/refrigerant pairs has also been extracted from the present experimental data.
