摘　　要：为建筑外窗附加保温层的手段是降低采暖期间建筑热负荷的重要途径之一,具有较强的节能潜力。以严寒地区典型单层工业厂房为研究对象,应用DesignBuilder能耗模拟软件对附加外窗保温层后的供暖季热负荷、外窗得失热情况和室温变化情况进行仿真,揭示了保温层材料、保温层附加时间对建筑能耗的影响;全时段为外窗附加PVC防寒膜的节能效果最优,热负荷降低7.2%,通过外窗的热量损失减少31.6%,并具有明显的性价比;夜间附加EPS保温板时室内热环境最稳定,其最佳厚度为33mm,但经济成本相对较高。研究结果可为严寒地区工业厂房的外窗保温提供数据支撑和理论依据。The means of attaching thermal insulation layer to the external windows of a building is one of the impor⁃tant ways to reduce the heating load of the building during the heating season,which has a strong potential for energy saving.Taking a typical single-story industrial plant in a cold region as the research object,the heating load,heat gain and loss of external windows,and natural room temperature change after attaching the external window insula⁃tion layer are simulated by applying Design Builder energy simulation software,revealing the influence of the insula⁃tion layer material and the time of attaching the insulation layer on the energy consumption of the building.The ener⁃gy saving effectiveness of attaching PVC cold-proof film to the external windows at full time is optimal,through which the heating load is reduced by 7.2%,the heat loss through the external windows is reduced by 31.6%,and it has obvious cost-effective.The indoor thermal environment is the most stable at night when attaching EPS thermal in⁃sulation panels,and its optimal thickness is 40mm,but the economic cost is relatively high.The results of the study may provide data support and theoretical basis for the external window insulation of industrial plants in cold regions.
