Résumé

A multilayer sheet type solid desiccant dehumidifier was constructed performing distinguished adsorption capacity and water removal efficiency. Micro sphere silica gel (M. S. Gel) with a pore diameter of 2.7 nm manufactured by AGC Si-Tech. Co., Ltd., Japan, was adopted as adsorbent that the characterized regeneration temperature was below 60 degree Celsius. The micron-sized desiccant particles were confined between metal mesh sheets without polymer binder elevating the water uptake capability. Instead of conventional honeycomb structure of the flow channels, the multilayered slit bed effectively lowered the fan power required to operate the process air. The device performance is evaluated by analyzing the dynamic heat and mass transfer characteristics during the adsorption and regeneration processes at various supply air conditions and desiccant bed thicknesses, demonstrating itself as a competitive alternative to existing solid desiccant dehumidifiers.
