Résumé

Due to fewer environmental problems and cost, the adsorption refrigeration systems are being paid a lot of attention in recent years. These systems prove to be a convenient substitution for the vapor compression and absorption refrigeration systems. The type of adsorbent plays a key role in the performance of adsorption refrigeration systems. Therefore, a lot of adsorbents have been introduced and analyzed by researchers. In the present paper, Zeolite 13X/CaCl2 is considered as a new adsorbent in a two-bed adsorption refrigeration system. The processes in different system components are simulated using the Simulink, Matlab software to achieve the optimum times for various processes. The simulation is first done for Silica gel RD type as a conventional adsorbent and the obtained results are compared with the available experimental data in literature. The validated model is then applied to the system with Zeolite 13X/CaCl2 as the adsorbent. The results show that the cooling capacity is increased by around 7.7% and 36% when the Zeolite 13X/CaCl2 is used instead of Silica gel/CaCl2 and Silica activated carbon/CaCl2, respectively.
