摘要
为了提高严寒地区窗墙交接处的热工性能,采用现场实测与计算机模拟的方法,系统分析了严寒气候条件下窗墙交接处缝隙宽度、位置的不同对室内热环境带来的影响,并提出窗墙交接处构造设计策略。模拟分析表明:在严寒地区,窗墙交接处缝隙对室内热环境影响很大。当窗体上部出现1 mm宽缝隙后,室内1.2 m高度处平均温度急剧下降2.7℃,之后缝隙宽度每增加1 mm,平均温度下降1℃左右。通过加大饰面层与窗框的接触面积,在室外一侧安装窗台板等方式均能够提高窗墙交接处的耐久性,减少窗墙交接缝隙对室内热环境的影响。
In order to improve the thermal performance of the window - wall junction in severe cold area, the impact of the different width and position of the window - wall junction on the indoor thermal environment is systematically analyzed by field measurement and computer simulation. And the window - wall junction design strategy is proposed. Simulation analysis shows that in the severe cold area, the gap of the window- wall junction has a great influence on the indoor thermal environment. When the 1 mm width gap appears in the upper part of the window, the average temperature at 1. 2 m height in the room drops sharply by 2. 7 ℃, and the average temperature drops about 1 ℃ for every 1 mm increase in the width of the gap. By increasing the contact area between the decorative layer and the window frame and installing the window sill plate on the outdoor side, the durability of the window - wall junction can be improved, and the influence of the gap of the window -wall junction on the indoor thermal environment can be reduced.
