摘要
利用有限差分法求解新型节能墙体砌块三维温度场和热阻 ,计算中将空气层的当量导热系数与空气层厚度相联系 ,使得计算结果更准确地反映了墙体砌块的热工性能。文中对影响砌块热阻的诸多因素进行分析 ,提出提高墙体砌块热阻的多种方法。
With finite differential method,three dimensional temperature field and thermal resistance of new type energy saving building blocks are calculated in this paper.Equivalent coeffcient of heat conductivity of air layer is connected with air layer thickness.Result of calculation reflects thermal characteristics of building blocks more accurate.This paper analyzes influencing factors of thermal resistance of building blocks and put forward many ways to enhance it.
