Fans - Procedures and methods to determine the energy efficiency for the electrical input power range of 125 W up to 500 kW

This document provides procedures and methods for measuring and/or calculating the energy efficiency and associated characteristics of fans when driven by electric motors. This document deals with the following fan types;
-   axial fan;
-   centrifugal forward curved fan, centrifugal radial bladed fan;
-   centrifugal backward curved fan without housing, including centrifugal backward aerofoil fans;
-   centrifugal backward curved fan with housing, including centrifugal backward aerofoil fans;
-   mixed flow fan;
-   cross flow fan;
-   jet fan.
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.
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;
-   fans that are designed specifically to operate in toxic, highly corrosive or flammable environments or in environments with abrasive substances, see Annex C.

Es gibt den Herstellern eine Anleitung für die Bereitstellung von Informationen für die Überwachungsbehörden, um das gesamte Ausmaß des Ventilators zu beschreiben, indem Grenzen, wesentliche Elemente und zusätzliche Teile beschrieben werden.
Einige Einheiten, die zuvor als Ventilatoren definiert wurden, werden nun als Ein-Richtung-Lüftungsanlagen definiert. Dieses Dokument erläutert und zeigt den Unterschied zwischen Ventilatoren und Ein-Richtung-Lüftungsanlagen anhand von Beispielen.
Diese Norm schließt Folgendes nicht mit ein:
-   Ein-Richtung-Lüftungsanlagen;
-   Ventilatoren, die speziell für den Betrieb in giftigen, stark korrosiven oder brennbaren Umgebungen oder in Umgebungen mit abrasiven Stoffen konstruiert wurden, siehe Anhang C.

Ventilateurs - Procédures et méthodes pour déterminer l'efficacité énergétique pour la gamme de puissance d'entrée électrique de 125 W jusqu'à 500 kW

Le présent document fournit des procédures et des méthodes permettant de mesurer et/ou de calculer le rendement énergétique et les caractéristiques associées des ventilateurs entraînés par des moteurs électriques. Le présent document couvre les types de ventilateurs suivants ;
-   ventilateur hélicoïdes ;
-   ventilateur centrifuge à aubes courbées vers l'avant, ventilateur centrifuge à aubes radiales ;
-   ventilateur centrifuge à aubes courbées vers l’arrière sans enveloppe, y compris les ventilateurs centrifuges à aubes profilées, courbées vers l’arrière ;
-   ventilateur centrifuge à aubes courbées vers l’arrière avec enveloppe, y compris les ventilateurs centrifuges à aubes profilées, courbées vers l’arrière ;
-   ventilateur hélico-centrifuge ;
-   ventilateur tangentiel ;
-   ventilateur accélérateur.
Il fournit des procédures et des méthodes permettant d'évaluer la conformité du rendement du ventilateur aux exigences minimales de rendement.
Le présent document prend en compte les ventilateurs individuels et les ventilateurs intégrés dans d'autres produits. Il donne aux fabricants des lignes directrices pour leur permettre de fournir aux autorités de surveillance des informations décrivant la portée exacte du ventilateur en précisant les limites, les éléments importants et les pièces supplémentaires.
Certaines unités précédemment identifiées comme étant des ventilateurs sont désormais définies comme des unités de ventilation unidirectionnelles. Le présent document explique et démontre au travers d'exemples, la différence entre les ventilateurs et les unités de ventilation unidirectionnelles.
La présente norme n'inclut pas :
-   les unités de ventilation unidirectionnelles ;
-   les ventilateurs conçus spécifiquement pour fonctionner dans des environnements toxiques, hautement corrosifs ou inflammables, ou dans des environnements contenant des substances abrasives, voir l’Annexe C.
