Abstract:

By using absorption and desorption characteristics, humidity control material based passive dehumidification can adjust indoor humidity without any mechanical equipment and energy consumption, which has good energy saving and ecological effects. Development of high-efficiency humidity control materials guarantees the effective implementation of this technology. Single humidity control material fails to meet the requirements of large moisture absorption capacity as well as high absorption and desorption rate, while composites can greatly overcome this problem. Fabrication of composite humidity control materials is one of the research hotspots in the fields of building energy saving and material science. In this paper, composite humidity control materials were divided into four categories: inorganic-inorganic, inorganic-organic, inorganic-biomass and organic-biomass. Characteristics of the above classifications are systematically summed up. Contents such as synthesis process of composite humidity control materials, humidity control performance like moisture holding capacity and absorption & desorption rate, and related research in buildings were summarized. In addition, based on the existing literature, key problems that need to be solved in the future research were sorted out. It is believed that the paper could provide some valuable references for the promotion of passive dehumidification technology based on humidity control materials.

Key words: building energy saving, passive dehumidification, humidity control material, sorption quantity, sorption rate

摘要:

利用调湿材料吸放湿特性来调节室内湿度的被动除湿技术,无需任何机械设备和能源消耗,具有较好的节能和生态效益。高效调湿材料的研制是该技术能否有效实施的前提,复合调湿材料很好地克服了单一调湿材料难以同时满足高吸湿容量和高吸放湿速度的要求,是建筑节能和材料科学领域的研究热点之一。本文将复合调湿材料分为无机-无机、无机-有机、无机-生物质、有机-生物质四大类,并针对上述分类的特点进行了系统的归纳与总结。主要概括了典型复合调湿材料的合成工艺、湿容量、吸放湿速率等调湿性能以及在建筑中的相关应用研究。同时,基于现有研究,梳理了今后研究中亟待解决的关键问题,以期为基于调湿材料的被动除湿技术的发展提供有价值的借鉴和参考。
