摘要
建筑物外门、外窗的热量损失,占全部热损失的比重很大。外门、外窗热量损耗的因素有传热系数、气密性、窗墙比与朝向,从建筑节能的角度对节能门窗进行设计、施工和质量控制,大幅降低热量损耗,是建筑节能的重要问题。
A large part of heat loss of buildings is from doors and windows, affected by factors of heat transmission coefficient, air-tightness, window-wall ratio and orientation. It is an important subject to control the design, construction and quality of doors and windows from point of view of architecture energy-saving.
