BS EN ISO 13789:2017规定了一种方法，并提供了计算稳态温度的惯例 建筑整体和部分建筑的传热和通风换热系数。它是 适用于热损失（内部温度高于外部温度）和热增益 （内部温度低于外部温度）。就本文件而言 或者，假设冷却空间温度均匀。附录C提供了一种稳态方法，用于计算相邻无条件空间的温度 到有条件的空间。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 12631:2017ISO 52000-1:2017ISO 14683:2017ISO 7345:1987ISO 10211:2017ISO 13370:2017ISO 10077-1:2017ISO 6946:2017ISO 10077-2:2017CEN/TS 16628:2014CEN/TS 16629:2014ISO/TR 52019-2:2017ISO/TR 52000-2:2017购买本文件时可提供的所有当前修改件均包含在本文件中。

BS EN ISO 13789:2017 specifies a method and provides conventions for the calculation of the steady-state transmission and ventilation heat transfer coefficients of whole buildings and parts of buildings. It is applicable both to heat loss (internal temperature higher than external temperature) and to heat gain (internal temperature lower than external temperature). For the purpose of this document, the heated or cooled space is assumed to be at uniform temperature.Annex C provides a steady-state method to calculate the temperature in unconditioned spaces adjacent to conditioned spaces.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 12631:2017ISO 52000-1:2017ISO 14683:2017ISO 7345:1987ISO 10211:2017ISO 13370:2017ISO 10077-1:2017ISO 6946:2017ISO 10077-2:2017CEN/TS 16628:2014CEN/TS 16629:2014ISO/TR 52019-2:2017ISO/TR 52000-2:2017All current amendments available at time of purchase are included with the purchase of this document.
