摘要
依据ISO有关标准 ,以温差比作为热桥影响区域的划分原则 ,通过简化的计算方法对常见的 6种热桥影响区域进行了计算。认为在计算热桥的影响区域时 ,除不开窗的墙面外 ,其他墙面若简化为无限大平面模型 ,按一维传热计算 ,存在较大误差。
By related ISO standards, takes temperature difference ratio as a criterion for definition of the influencing zone of a thermal bridge. Calculates six typical thermal bridge influencing zones by a simplified method. Considers that when calculating the influencing zone of a thermal bridge in the exterior wall and simplifying it as a one dimension infinite plane, the result may have a major error.
