Résumé

This article presents the dynamic modelling of a single effect two-bed adsorption chiller utilizing the composite adsorbent "CaCl2 confined to KSK silica gel" as adsorbent and water as adsorbate, which is based on the experimentally confirmed adsorption isotherms and kinetics data. Compared with the experimental data of conventional adsorption chiller based on RD silica gel + water pair, we found that the new working pair provides better cooling capacity and performances. From numerical simulation, it is also found that the cooling capacity can be increased up to 20% of the parent silica gel + water adsorption chiller and the COP can be improved up to 25% at optimum conditions. We also demonstrate here that the best peak chilled water temperature suppression, and the maximum cooling capacity can be achieved by the optimum analysis for both cycles.
