REGULATION (EU) No 327/2011风机/风扇Erp能效法规-欧盟CE认证

COMMISSION REGULATION (EU) No 327/2011 of 30 March2011 implementing Directive 2009/125/EC of the European Parliamentand of the Council with regard to ecodesign requirements for fansdriven by motors with an electric input power between 125 W and 500kW

 (EU) No 327/2011关于电机驱动的风机的电力输入功率在125 W至500kW之间的能效要求

1 适用范围

‘Fan’means a rotary bladed machine that is used to maintain a continuousflow of gas, typically air, passing through it and whose work perunit mass does not exceed 25 kJ/kg, and which:“风机”指的是一种旋转叶片的机器，用于保持气体(通常是空气)的连续流动，通过风机，其单位质量的工作不超过25千焦/公斤，并且:

— isdesigned for use with or equipped with an electrical motor with anelectric input power between 125 W and 500 kW (≥ 125 W and ≤ 500kW) to drive the impeller at its optimum energy efficiency point,配合或配用电输入功率在125w ~ 500kw(≥125w~≤500kw)的电动机，在能效点驱动叶轮，

— is anaxial fan, centrifugal fan, cross flow fan or mixed flow fan,是轴流风机、离心风机、横流风机或混流风机，

— mayor may not be equipped with a motor when placed on the market orput into service; 在投放市场或投入使用时，可配备或不配备电机;

2 Measurementcategory测量分类

1)‘Measurement category A’ means an arrangement where the fan ismeasured with free inlet and outlet conditions.

2)‘Measurement category B’ means an arrangement where the fan ismeasured with free inlet and with a duct fitted to itsoutlet.

3)‘Measurement category C’ means an arrangement where the fan ismeasured with a duct fitted to its inlet and with free outletconditions.

4)‘Measurement category D’ means an arrangement where the fan ismeasured with a duct fitted to its inlet andoutlet.

4 Calculationmethod风机能效计算方法

ηe =Pu(s) / Pe

where:

η e isthe overall efficiency;

P u(s)is the fan gas power, determined according to point 3.3, of the fanwhen it is operating at its optimal energy efficiencypoint;

P e isthe power measured at the mains input terminals to the motor of thefan when the fan is operating at its optimal energy efficiencypoint;

其中风量功率gas power, Pu(s)按照如下公式计算

(a)where the fan has been measured according to measurement categoryA, fan static gas power P us is used from the equation P us = q· p sf· k ps;

(b)where the fan has been measured according to measurement categoryB, fan gas power P u is used from the equation P u = q · p f · k p;

(c)where the fan has been measured according to measurement categoryC, fan static gas power P us is used from the equation P us = q· p sf· k ps;

(d)where the fan has been measured according to measurement categoryD, fan gas power P u is used from the equation P u = q · p f · k p.
