摘　　要：为了研究分析外窗节能影响因素,采用有限元仿真模拟软件Ansys,针对4种不同腔体结构的热工性能进行分析,得出适宜寒冷地区建筑的腔体结构为窗框CK-New。采用建筑能耗模拟软件Designer’s Simulation Toolkit(DeST)模拟寒冷地区典型建筑采用热工性能和遮阳性能不同的外窗所产生的建筑能耗,通过对比分析,当外窗平均传热系数为2.40W/(m2·K)时,典型建筑能耗最小,且对于寒冷地区典型居住建筑来说,建议不采取外遮阳措施,或采取能满足建筑对冬季和夏季阳光不同需求的外遮阳措施。In order to investigate the factors affecting the energy-saving efficiency of exterior windows^ this paper adopts Ansys simulation to analyze the thermal properties of four different cavity structures. The result shows that the cavity structure is CK-New for the cold region By employing Designer＇s Simulation Toolkit （DeST） , this paper simulates typical buildings in cold re-gion, which adopt different thermal properties and different shading performance of external windows of building energy con-sumption Through comparative analysis, when the average heat transfer coefficient of outer windows is 2.40 W/ （m^2·K） , the typical building energy consumption is the smallest For the typical residential buildings in cold region, it is recommended not to take external shading measures, or to meet the construction of the different needs of winter and summer sun shading measures.
