BS EN ISO 10211:2017规定了热桥的三维和二维几何模型规范，用于热流的数值计算，以评估建筑物或其部分的整体热损失，以及最低表面温度，以评估表面冷凝的风险。这些规范包括模型的几何边界和细分，以及 边界条件，以及要使用的热值和关系。 本文件基于以下假设:所有物理性质与温度无关；建筑构件内没有热源。本文件还可用于推导线性和点热传导率，以及 表面温度系数。注:引言中的表1显示了本文件在EPB标准中的相对位置 在ISO 52000-1规定的模块化结构中。交叉引用:ISO 10456:2007 ISO 6946: 2017ISO 13789:2017ISO 7345:1987ISO 13370:2017ISO 52000-1:2017ISO 13788:2012 ED2ISO 10077-2:2017EN 673:2011ISO/TR 52019-2:2017ISO/TR 52000-2:2017CEN/TS 16628:2014ISO 14683:2017CEN/TS 16629:2014购买本文件时可提供的所有当前修改件均包含在购买本文件中。

BS EN ISO 10211:2017 sets out the specifications for a three-dimensional and a two-dimensional geometrical model of a thermal bridge for the numerical calculation ofheat flows, in order to assess the overall heat loss from a building or part of it, andminimum surface temperatures, in order to assess the risk of surface condensation.These specifications include the geometrical boundaries and subdivisions of the model, the thermal boundary conditions, and the thermal values and relationships to be used.This document is based upon the following assumptions:all physical properties are independent of temperature;there are no heat sources within the building element.This document can also be used for the derivation of linear and point thermal transmittances and of surface temperature factors.NOTE Table 1 in the Introduction shows the relative position of this document within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.Cross References:ISO 10456:2007ISO 6946:2017ISO 13789:2017ISO 7345:1987ISO 13370:2017ISO 52000-1:2017ISO 13788:2012 ED2ISO 10077-2:2017EN 673:2011ISO/TR 52019-2:2017ISO/TR 52000-2:2017CEN/TS 16628:2014ISO 14683:2017CEN/TS 16629:2014All current amendments available at time of purchase are included with the purchase of this document.
