| 摘 要： | 泡沫玻璃外墙外保温系统由基层墙体、粘结层、保温层、保护层和饰面层组成.在基层和保温层相同时,分别计算了饰面采用面砖和涂料的2种保温系统的平均密度、平均比热容、热阻、导热系数及热惰性系数.通过对计算结果的分析比较发现,2种保温系统的总热阻和总传热系数相差均小于3.0%,热情性指标相差小于3.3%.从热工性能的角度分析,采用2种不同饰面层和保护层对泡沫玻璃保温系统的热物性影响不大,因此,应从材料和建造成本以及对环境的影响等方面选取最优的保温系统结构.

| Abstract: | The exterior wall external insulation system consists of five sections including primary wall,bonding layer,insulation layer,protective layer and decorative coating.When the primary wall is same with the insulation layer,the thermal parameters such as average density,average specific heat capacity,thermal resistance,thermal conductivity and thermal inertia factor,are calculated for two insulation systems with decorative coatings and protection layer.The results show that the difference in thermal resistance... |
