摘　　要：外窗是住宅围护结构保温性能最薄弱的部位,外窗传热系数主要取决于玻璃、窗框型材的热工性能及其组合形式,是外窗节能改造的主要指标。对严寒地区外窗传热的决定因素进行分析研究,计算出常用外窗的传热系数U值,同时对外窗改造的节能性与经济性进行了评价。Outside windows of the residential building envelope are the weakest part of the heat insulation performance. Outside window heat transfer coefficient is mainly decided by the glass, the window frame profile thermal performance and the combination form. They are main indicators of outside window energy-saving transformation. This article analyzes the window heat transfer determining factor in the severely cold areas, calculates the common heat transfer coefficient value U, and evaluates energy-saving and economic performance of outside window transformation.

关 键 词：外窗改造 传热系数 节能性 经济性
