标准摘要
[中文适用范围]： 本文件规定了用于数值计算线性热传递系数、点热传递系数和内部表面温度的建筑热桥的三维和二维几何模型规格。这些规格包括模型的几何边界和细分、热边界条件以及要使用的热值和关系。本文件基于以下假设：所有物理属性与温度无关；建筑构件内没有热源。本文件也可用于推导线性和点热传递系数及表面温度系数。 [外文原描述]： 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 of - heat flows, in order to assess the overall heat loss from a building or part of it, and - minimum 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. ISO 10211:2017 is based upon the following assumptions: - all physical properties are independent of temperature; - there are no heat sources within the building element. ISO 10211:2017 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 ISO 10211:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.
