Recently, solid dehumidification systems have been widely used in various industries and are effective in buffering the humidity in the environment. The dehumidification materials and structure of the system have a significant influence on the over system performance. This study aims to quantitatively evaluate dehumidification materials produced from activated carbon fibre cloth (ACFC) and coconut-shell activated carbon (CAC) for suitability in a dehumidification shutter system. First, the physical and chemical properties of ACFC and CAC were characterised via N₂ adsorption–desorption isotherms, thermogravimetric analysis, and Fourier transform infrared spectroscopy. Second, the adsorption of water vapour was experimentally investigated, including adsorption kinetics, adsorption isotherms, and thermodynamics, and fitted by various models. The results show that the specific surface areas of ACFC and CAC were 1425 m²/g and 986 m²/g, respectively, while the total pore volume were 0.748 cm³/g and 0.554 cm³/g, respectively. At a relative humidity of 98% and an adsorption temperature of 298 K, the maximum water vapour adsorption capacities of ACFC and CAC were 395.6 mg/g and 277.6 mg/g, respectively. More importantly, ACFC retained a high adsorption capacity after five adsorption/regeneration cycles, indicating that it is an effective and renewable adsorbent for dehumidification. Third, a novel dehumidification shutter system was designed and constructed. The dehumidification performance and thermal comfort indices of the system were then analysed. In conclusion, the dehumidification shutter system fabricated using ACFC is a feasible and effective way to buffer the indoor humidity when solar energy is chosen as the renewable regeneration heat source.

近来，固体除湿系统已广泛用于各种工业中，并且在缓冲环境中的湿度方面是有效的。系统的除湿材料和结构会对整个系统的性能产生重大影响。这项研究旨在定量评估由活性炭纤维布（ACFC）和椰子壳活性炭（CAC）生产的除湿材料在除湿百叶窗系统中的适用性。首先，通过N ₂表征ACFC和CAC的物理和化学性质吸附-解吸等温线，热重分析和傅里叶变换红外光谱。其次，对水蒸气的吸附进行了实验研究，包括吸附动力学，吸附等温线和热力学，并通过各种模型进行拟合。结果表明，ACFC和CAC的比表面积分别1425米² / g，且986米² / g时，分别，而总的孔体积分别为0.748厘米³ / g且0.554厘米³/ g。在98％的相对湿度和298 K的吸附温度下，ACFC和CAC的最大水蒸气吸附量分别为395.6 mg / g和277.6 mg / g。更重要的是，ACFC在五个吸附/再生循环后仍保持了高吸附容量，这表明ACFC是一种有效的可再生除湿吸附剂。第三，设计并建造了一种新型的除湿百叶窗系统。然后分析了系统的除湿性能和热舒适指数。总之，除湿快门系统制造使用ACFC是当太阳能被选择作为再生再生热源缓冲室内湿度一种可行而有效的方法。
