摘　　要：采用数值计算方法,计算分析了带外保温层结构的空心砖墙体在周期性非稳态边界条件下,墙体内部的温度分布及传热量,分析研究了不同孔型空心砖传热性能的差异,得出保温层厚度对空心砖墙体的非稳态传热性能的影响。By numerical method, the temperature distribution and heat flux of the hollow brick wall with exterior insulation were calculated under periodic unsteady boundary conditions. Based on the detailed data, the variation of the heat transfer performance between different hollow brick wall were studied, and the influence of thickness of the insulation materials on unsteady heat transfer has been analyzed.
