摘要
在地下室传热数理模型的基础上,借鉴IPTE技术的基本思想,将计算区域划分为八个长方形区域,由热流连续和边界条件确定傅里叶系数,对每个区域用分离变量法进行了求解。通过对三种建筑材料构建工程传热量和温度分布的计算,分析了围护结构建筑材料对传热过程的影响。
On the basis of the mathematical model of heat transfer, referring the principle idea of IPTE (interzone temperature profile estimation) technology, divides the calculation zone into eight rectangles, determines the Fourier coefficients by the continuity of heat flux and boundary conditions, and obtains the solutions for all the parts using the separation of variable method. Analyses the effect of the building materials on the heat transfer of building envelope according to the calculation of heat flux and temperature in three buildings with various building materials.
