标准范围
本文件定义了确定风扇能量指数（FEI）的计算方法，FEI是风扇工作点的能效指标。该指标为在给定风扇工作点比较不同风扇类型和尺寸的风扇能效提供了标准化和一致的基础。本文件适用于电动机驱动的风机和无驱动的风机。不适用于循环风机或风幕。风机能量指数只能计算在最小空气功率125以上的风机工作点？W（其中空气功率是体积流量和风机静压的乘积）或最小体积流量2,0以上？立方米/秒。
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 m3/s.
