摘　　要：干燥剂作为影响固体吸附除湿系统性能的关键因素,关乎整个除湿系统的性能指标和经济性,一直以来都是固体吸附除湿技术的研究重点。复合干燥剂不仅水汽吸附量大、吸附/解吸速度快,而且具有良好的热稳定性和吸湿稳定性,是近年来固体除湿空调系统研究中应用最为广泛的干燥剂材料。本文详细介绍了复合干燥剂近年来的研究进展,主要包括硅胶基复合干燥剂、分子筛基复合干燥剂、碳基复合干燥剂、天然岩石基复合干燥剂和高分子复合干燥剂等,对其除湿性能特点进行分析,并对复合干燥剂今后的发展趋势进行了展望。？Desiccants, as a key factor affecting the performance of solid desiccant cooling system, have always been the research focus due to it decides performance and economy of the entire cooling system. Composite desiccants are the most extensively used desiccant materials in solid desiccant cooling system in recent years because of large water uptake, high adsorption/desorption rate, good thermal and hygroscopic stability. This paper introduces the research progress of composite desiccants, mainly including silica gel-based composite desiccants, molecular sieve-based composite desiccants, carbon-based composite desiccants, natural rock-based composite desiccants and polymer composite desiccants. The dehumidification performances are especially compared, and the future development trend of composite desiccants is prospected.
