建筑构件的热性能.动态热特性.计算方法

[中文适用范围]： 本文件规定了与完整建筑构件的动态热行为相关的特性，并提供了计算方法。 它还规定了使用建筑构件所需的建筑材料的信息。 由于这些特性取决于材料组合形成建筑构件的方式，因此本文件不适用于建筑材料或未完工的建筑构件。 本文件中给出的定义适用于任何建筑构件。 为由基本上均质的建筑材料的平面层组成的平面部件提供了简化的计算方法。 附录 C 提供了在某些有限情况下估算热容的更简单方法。 这些方法适用于确定估计能耗所需的动态热特性。 然而，这些近似值并不适合产品表征。 注：引言中的表 1 显示了本文件在 ISO 52000-1 中规定的模块化结构的 EPB 标准集中的相对位置。 [外文原描述]： ISO 13786:2017 specifies the characteristics related to the dynamic thermal behaviour of a complete building component and provides methods for their calculation. It also specifies the information on building materials required for the use of the building component. Since the characteristics depend on the way materials are combined to form building components, ISO 13786:2017 is not applicable to building materials or to unfinished building components. The definitions given in ISO 13786:2017 are applicable to any building component. A simplified calculation method is provided for plane components consisting of plane layers of substantially homogeneous building materials. Annex C provides simpler methods for the estimation of the heat capacities in some limited cases. These methods are suitable for the determination of dynamic thermal properties required for the estimation of energy consumption. These approximations are not appropriate, however, for product characterization. NOTE Table 1 in the Introduction shows the relative position of ISO 13786:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.
