摘　　要：对一种新型太阳能直接作用再生固体除湿材料进行了热物性测试研究,包括不同含湿量状态下除湿材料的等效导热系数、不同模拟太阳辐射工况下材料的辐射穿透率等。测试结果表明,除湿材料的等效导热系数与含湿率、水分饱和度密切相关。在未饱和状态下,等效导热系数均随着含湿量的增加而增大,并在某一范围内呈现规律性变化,到达饱和状态后,等效导热系数随着含湿量的增大而减小;测试了除湿材料的等效导热系数及辐射穿透率,初步确定了除湿床的床体厚度,为除湿系统的优化设计奠定了基础。This paper studies the thermal physical property of a new solar solid desiccant material regenerating directly with solar energy,ineluding the equivalent thermal conductivity of different moisture eontent conditions,material radiation penetration rate under different simulated solar radiation conditions,etc. The results show that the equivalent thermal conductivity of desieeant material is related with moisture rate,water saturation and density.＂ In unsaturated state,the equivalent thermal conductivity increases with moisture content, and present regularity changes in a certain range,but the equivalent thermal conductivity along with the moisture content is decreased in saturated state. The equivalent thermal conductivity eoefficient and radiation penetration rate of desiecant material,ean preliminarily provide the basis for the thiekness of dehumidification bed and lay a foundation for the optimization design of desiccant system.
