| 摘 要： | 冬季通过建筑围护结构传递的热量由3个因素决定:壁体内表面换热阻、壁体外表面换热阻及壁体材料层的导热系数。这3个因素受室内外热冷源、风速及材料层的含湿量影响。通过对一使用10年左右住宅建筑的现场测试与理论计算对比得出:在进行冬季围护结构热工计算时,应对以上3个参数根据不同实际情况作相应的修正。

| Abstract: | The heat transfer through the building envelope in winter have three factors: the inner surface resistance of the wall,the outer surface resistance of the wall and the thermal conductivity of the material.These three factors are effected by the source of indoor and outdoor hot and cold,wind speed and the moisture of the material layer.Testing a residential building that had been used for ten years and calculating we can concluded: when we do the calculation of heat transfer theory of building envelope in th... |
