标准摘要
[中文适用范围]： 本文件定义了确定风扇能量指数 (FEI) 的计算方法，该指数是风扇工作点的能效指标。该指标为比较给定风扇工作点下不同类型和尺寸的风扇能量性能提供了标准化和一致的基础。本文件适用于由电动机驱动的风扇和无驱动器的风扇。它不适用于循环风扇或空气幕。风扇能量指数只能针对最低空气功率高于 125 W（空气功率是体积流量和风扇静压的乘积）或最低体积流量高于 2.0 m3/s 的风扇工作点进行计算。 [外文原描述]： This document defines the calculation method for determining the fan energy index (FEI), which is an energy efficiency metric for fan duty points. This metric provides a standardized and consistent basis to compare fan energy performance across fan types and sizes at a given fan duty point. This document is applicable to fans driven by electric motors and fans without drives. It is not applicable to circulating fans or air curtains. The fan energy index can only be calculated for fan duty points above a minimum air power of 125 W (where air power is the product of volume flow rate and fan static pressure) or above a minimum volume flow rate of 2,0 m 3 /s.
