Fan System Efficiency and Fan System Input Power Calculation
This standard provides a method to estimate the input power and overall efficiency of an extended fan system. An extended fan system is composed of a fan and an electric motor but may also include a transmission and a motor controller. While direct measurement of fan system performance is preferred, the large number of fan system configurations often makes testing impractical. This standard offers a standardized method to estimate fan system performance by modeling commonly used components. Calculations reported in accordance with this standard offers fan users a tool to compare alternative fan system configurations in a consistent and uniform manner. This document does not provide selection guidance. Users must assure that selected components have sufficient capacity and are configured to produce the desired results.
