大空间建筑夏季屋顶复合换热和交叉效应的研究

Study on complex heat transfer and intercoupling effect of a large space building ceiling in summer

本文用不可逆热力学分析研究大空间建筑夏季屋顶复合换热和交叉效应，以空调规范手册数据为依据，将多表面的辐射简化为两个平行平板的辐射，同时引入了虚拟在面的等效黑度和半透明表面的附加黑度两个参数，最后拟合得到了该复合传热的唯象方程。与实验数据对比，结果表明利用不可逆热力学研究大空间建筑夏季复合传热过程是简便有效的。

complex heat transfer and intercoupling effect of a large space building ceiling in summer is stud- ied by means of irreversible themodynamics. Based on the data of the air conditioning designing handbook, inducing equivalent darkness of visual surface and additional darkness of semitransparent surface,phenomeno- logical equations is fitted and obtained. Compared with the experimental data,the result shows that study on complex heat transfer process and intercoupling effect of a large space building ceiling in summer by means of irreversible thermodynamics is simple and available.
