外窗作为建筑外围护结构中保温性能最薄弱的环节,因此对外窗进行优化设计以提高建筑外窗的保温性能具有重大意义.本文提出一种新型的软帘窗,并模拟分析软帘窗的保温性能及其对室内热环境的影响,模拟表明当软帘窗空气层厚度在2.4 mm时传热系数最低,保温效果最好,此时软帘窗的传热系数为2.14 W/(m·K),使用软帘窗可以使严寒地区农村室内夜晚温度提升10 ℃以上,从而能有效地改善室内热环境、提高室内人员的热舒适性.

As the weakest link in the insulation performance of the building envelope,external Windows consume about 30% of the total heat of the building.Therefore,it is of great significance to optimize the design of exterior Windows to improve the thermal insulation performance of building exterior Windows.In this paper, a new kind of soft curtain,window and simulation soft curtain window insulation and its influence on the indoor thermal environment,simulation shows that when the soft curtain window air layer thickness 2.4 mm heat transfer coefficient is the lowest,the heat preservation effect best,the soft curtain window heat transfer coefficient is 2.14 W/(m·K),using a soft shade Windows can make cold region rural interior night temperature above 10 ℃,which can effectively improve the indoor thermal environment,improve the indoor thermal comfort.
