建筑围护结构的动态热平衡模型及实例分析

Building Envelope's Dynamic Heat Balance Model and Example Analysis

在小区微环境的研究中,正确地获得建筑围护结构外表面的温度,并以此作为温度场计算的边界条件是非常重要的。本文区别已往仅考虑太阳辐射的静态方法,建立了一个考虑围护结构蓄热和传热的动态建筑围护结构热平衡模型。并用该模型计算了济南夏季某日某单栋建筑各围护结构外表面的温度。

In research of residential area＇s microclimate, it is very important to obtain outside surface＇s temperature of building envelope exactly and to set it as boundary condition when calculating temperature field. Considering its heat storage and heat transfer, this paper set up a dynamic heat balance model of building envelope which is different from former static approach. Building＇s outside surface＇s temperature is calculated in summer time using the model.
