Adsorption heat transformation (AHT) systems can play a major role in protecting our environment by decreasing the usage of fossil fuels and utilizing natural and alternative working fluids. The adsorption isotherm is the most important feature in characterizing an AHT system. There are eight types of International Union of Pure and Applied Chemistry (IUPAC) classified adsorption isotherms for different “adsorbent-adsorbate” pairs with numerous empirical or semi-empirical mathematical models to
This work deals with the use of adsorption refrigerant cycles driven by waste heat of near ambient temperature. A parametric study was conducted by computer simulation to determine the effects of operating conditions on cooling output and coefficient of performance (COP). A simulation program verified the influence of operating temperatures (hot and cooling water), water flow rates, and adsorption-desorption cycle times. The most influential parameter is the operating temperatures, followed by w
This paper presents adsorption isotherm data of CO2 onto two different types of highly porous activated carbons (ACs) for temperatures ranging from (−18 to 80) °C and pressures up to 10 MPa. The assorted adsorbents are activated carbon fiber (ACF) of type A-20 and activated carbon powder of type Maxsorb III. Adsorption isotherm data have been obtained using a volumetric technique and fitted to the Dubinin−Astakhov (D−A), Tóth, Langmuir, and modified D−A equations. The latter considers the pseudo
