标准摘要
[中文适用范围]： 本文件规定了空间供暖、空间制冷和生活热水 (DHW) 水基分配系统的能源绩效计算。 本文件适用于配水到空间的热通量以及相关泵的辅助能源。 可以计算任何时间间隔（小时、月和年）的热通量和泵的辅助能量。 输入和输出数据是时间间隔的平均值。 除了计算水基分配系统的能源绩效之外，还可以使用测量值，只要它们遵循整个绩效计算的时间间隔或可以划分为这些时间间隔即可。 [外文原描述]： This document specifies the energy performance calculation of water-based distribution systems for space heating, space cooling and domestic hot water (DHW). This document is applicable to the heat flux from the distributed water to the space and the auxiliary energy of the related pumps. The heat flux and the auxiliary energy for pumps can be calculated for any time interval (hour, month and year). The input and output data are mean values of the time interval. Instead of calculating the energy performance of water-based distribution systems, it is also possible to use measurements as long as they follow the time intervals of the whole performance calculation or can be divided into those time intervals.
