| 摘 要： | 利用有限元分析软件包Femlab,进行建筑围护结构三维导热分析。算例给出了一典型含外墙、外窗、结构柱、梁和楼板的围护结构内部三维温度分布。可视化图像以及数据计算结果,显示了外保温与内保温以及窗户内置与外置等不同构造对围护结构温度分布、散热量的影响,外保温更有利于隔断冷(热)桥。

| Abstract: | The three dimentional heat conduction in building enclosures is simulated by the Femlab, a simulation software based on the finite element analysis(FEA),and a case study is presented. The internal three dimentional temperature distribution of the typical building enclosure which includes the exposed wall, external window, constructional column, beam and floorslab is given. The visual and numerical results show that different thermal insulation and window installation have influence on the temperature distribution and heat dissipating capacity of the building enclosure. |
