摘要
不同保温材料和墙体材料在不同含水率状态下的热导率是不同的,因此不同材料砌筑的墙体在含水率不同时,热阻也不同。通过对保温材料热导率、砌筑墙体热阻在不同含水率条件下的变化情况进行研究,分析含水率对墙体热阻的影响规律,为工程现场实测达到湿稳定时墙体的热阻提供参考。
Different heat insulation materials and wall materials have different thermal conductivities at different moisture contents, so the walls built with different materials have different thermal resistances at different moisture contents. Influence law of moisture content on thermal resistance of wall is analyzed after researches on thermal conductivity of heat insulation material and thermal resistance of masonry wall at different moisture contents, to provide references for field measurement of thermal resistance of wall after the humidity becomes stable.
