夏热冬冷地区新型墙体材料传热性能研究

摘要

In this paper, a theoretical analysis is carried out on the thermal insulation of wall material, according to a rule in design standard for energy efficiency in hot summer and cold winter zone, conducting a thermal insulation property checking calculation for four kinds of wall materials： new wall materials of autoclaved aerated concrete block and normal concrete small-sized hollow block, traditional wall materials of common clay brick and experimental wall material of hollow plaster slab. Also through testing on insulation on single hollow plaster slab in cold winter, a conclusion has been drawn that thermal performance of building envelope is related to the difference of indoor and outdoor relative humidity in hot summer and cold winter zone.%根据夏热冬冷地区国家节能标准规范验算了新型墙体材料蒸压加气混凝土砌块及普通混凝土小型空心砌块墙体、传统的红色粘土砖墙体以及实验所用的石膏空心砌块墙体的保温隔热性能。并通过对石膏空心砌块墙体材料进行冬季保温测试，得出夏热冬冷地区围护结构热工性能与室内外相对湿度差值有关。
