 Performance comparisons of honeycomb-type adsorbent beds (wheels) for air dehumidification with various desiccant wall materialsLi-Zhi Zhang, Huang-Xi Fu, Qi-Rong Yang and Jian-Chang Xu Energy, 2014, vol. 65, issue C, 430-440 Abstract: This study aims at comparing the performance of honeycomb type adsorbent beds (or desiccant wheels) for air dehumidification with various solid desiccant wall materials, from a viewpoint of system operation. A mathematical model is proposed and validated to predict the cyclic behaviors of the cycling beds or wheels. The influences of regeneration air temperature, process air temperature, and humidity on the coefficient of performance (COP), specific dehumidification power (SDP) and dehumidification efficiency (εd) are predicted with various desiccant wall materials. Totally ten most commonly used desiccant materials are considered, with different adsorption and thermophysical properties. It is found that of the 10 materials, the silica gel 3A and silica gel RD perform better than other desiccants for air dehumidification under typical working conditions and driven by low grade waste heat. The results provide some insights and guidelines for the design and optimization of honeycomb type adsorption beds or desiccant wheels.
