Fans — Efficiency classification for fans — Part 6: Calculation of the fan energy index
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…
