Abstract

Mass transfer resistance within the adsorbent felt, governed by pore diffusion, limits adsorption efficiency. Current gas and solid side resistance models, which cover both micro- and macro-pore diffusion, are complex due to their numerous parameters. Sometimes, adsorbate transfer in the felt is predominantly controlled by macro-pore diffusion. This paper uses two key assumptions to introduce a simplified macro-pore diffusion model, distilled from a detailed macro–micro pore diffusion model. The model’s accuracy was confirmed by simulating two desiccant wheels, demonstrating its effectiveness in streamlining adsorbent felt analysis and predicting mass transfer dynamics.

简化吸附剂毡的双分散孔隙扩散模型

吸附毡内部的传质阻力受孔隙扩散的影响，限制了吸附效率。目前的气体和固体侧阻力模型既包括微孔扩散，也包括大孔扩散，但由于参数众多，因此非常复杂。有时，毡中的吸附剂转移主要由大孔扩散控制。本文利用两个关键假设，介绍了一个简化的宏观孔隙扩散模型，该模型是从详细的宏观-微观孔隙扩散模型中提炼出来的。通过模拟两个干燥剂轮，证实了该模型的准确性，证明了它在简化吸附剂毡分析和预测传质动力学方面的有效性。

期刊介绍： The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling. As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews. Papers are published in either English or French with the IIR news section in both languages.
