Résumé

This work comes as a part of a series of researches carried out by our team to study and present new materials with distinctive properties suitable for adsorption applications. As we previously studied employment of many Freons within the adsorption cooling systems, this paper expresses a study using HFC404A with activated carbon (Maxorb III). Adsorption of Maxsorb III/HFC404A pair has been estimated experimentally at different temperatures ranging from 25 to 75 °C. Dubinin-Astakhov (D-A) and Tóth equations have been fitted with the experimental data to evaluate the adsorption isotherm, while the adsorption kinetic is evaluated by linear driving force model (LDF) and Fickian diffusion (FD) equations. The maximum adsorption capacity is 2.2 kg R404A/kg activated carbon. The numerical values of the activation energy (Ea) and the pre-exponential coefficient (Dso) are evaluated to be 3429.27 kJ/kg and 5.35×10–13, respectively. Transient simulation modeling has been carried out to predict performance of adsorption cooling system under different operating temperatures of Maxsorb III/HFC404A. Optimum recorded coefficient for performance and specific cooling power is 0.23 and 275 W/kg, respectively.
