Fans — Procedures and methods to determine the energy efficiency for the electrical input power range of 125 W up to 500 kW
Abstract
This document provides procedures and methods for measuring and/or calculating the energy efficiency and associated characteristics of fans when driven by electric motors. It provides procedures and methods to evaluate the compliance of the fan efficiency against minimum efficiency requirements. This document includes stand-alone fans and fans that are integrated in other products. It gives guidance to manufacturers in providing information to surveillance authorities to describe the full extent of the fan by describing boundaries, significant elements and additional parts. Jet fans are included in the Regulation 327/2011. This document covers the requirements for labelling and technical information but provides no reference for the determination of their efficiency. Refer to EN ISO 13350:2015 for determination of that products efficiency. Some units previously identified as fans are now defined as Uni-Directional Ventilation Units. This document explains and shows by way of examples the difference between fans and Uni-Directional Ventilation Units. This standard does not include Uni-Directional Ventilation Units (please refer to EN 172911).
