ANNEX I
ECODESIGN REQUIREMENTS FOR FANS
1. Definitions for the purposes of Annex I
(1) ‘Measurement category’ means a test, measurement or usage arrangement that defines the inlet and outlet
conditions of the fan under test.
(2) ‘Measurement category A’ means an arrangement where the fan is measured with free inlet and outlet conditions.
(3) ‘Measurement category B’ means an arrangement where the fan is measured with free inlet and with a duct fitted
to its outlet.
(4) ‘Measurement category C’ means an arrangement where the fan is measured with a duct fitted to its inlet and
with free outlet conditions.
(5) ‘Measurement category D’ means an arrangement where the fan is measured with a duct fitted to its inlet and
outlet.
(6) ‘Efficiency category’ means the fan gas output energy form used to determine the fan energy efficiency, either
static efficiency or total efficiency, where:
(a) ‘fan static pressure’ (p sf ) has been used to determine fan gas power in the efficiency equation for fan static
efficiency; and
(b) ‘fan total pressure’ (p f ) has been used to determine fan gas power in the efficiency equation for total
efficiency.
(7) ‘Static efficiency’ means the energy efficiency of a fan, based upon measurement of the ‘fan static pressure’ (p sf ).
(8) ‘Fan static pressure’ (p sf ) means the fan total pressure (p f ) minus the fan dynamic pressure corrected by the Mach
factor.
(9) ‘Stagnation pressure’ means the pressure measured at a point in a flowing gas if it were brought to rest via an
isentropic process.
(10) ‘Dynamic pressure’ means the pressure calculated from the mass flow rate, the average gas density at the outlet
and the fan outlet area.
(11) ‘Mach factor’ means a correction factor applied to dynamic pressure at a point, defined as the stagnation pressure
minus the pressure with respect to absolute zero pressure which is exerted at a point at rest relative to the gas
around it and divided by the dynamic pressure.
(12) ‘Total efficiency’ means the energy efficiency of a fan, based upon measurement of the ‘fan total pressure’ (p f ).
(13) ‘Fan total pressure’ (p f ) means the difference between the stagnation pressure at the fan outlet and the stagnation
pressure at the fan inlet.
(14) ‘Efficiency grade’ is a parameter in the calculation of the target energy efficiency of a fan of specific electric input
power at its optimum energy efficiency point (expressed as parameter ‘N’ in the calculation of the fan energy
efficiency).
(15) The ‘target energy efficiency’ (η target ) is the minimum energy efficiency a fan must achieve in order to meet the
requirements and is based on its electrical input power at its point of optimum energy efficiency, where η target is
the output value from the appropriate equation in Section 3 of Annex II, using the applicable integer N of the
efficiency grade (Annex I, Section 2, Tables 1 and 2) and the electrical power input P e(d) of the fan expressed in
kW at its point of optimum energy efficiency in the applicable energy efficiency formula.
(16) ‘Variable speed drive (VSD)’ means an electronic power converter integrated — or functioning as one system —
with the motor and the fan, that continuously adapts the electrical power supplied to the electric motor in order
to control the mechanical power output of the motor according to the torque-speed characteristic of the load
being driven by the motor, excluding variable voltage controllers where only the supply voltage for the motor is
varied.
(17) ‘Overall efficiency’ is either ‘static efficiency’ or ‘total efficiency’, whichever is applicable.
2. Fan energy efficiency requirements
The minimum energy efficiency requirements for fans are set out in Tables 1 and 2.

ANNEX II
MEASUREMENTS AND CALCULATIONS
1. Definitions
for
the
purposes
of
Annex
II
(1) ‘Inlet stagnation volume flow rate’ (q) is the volume of gas that passes through the fan per unit of time (in
m 3 /s) and is calculated on the basis of the mass of gas moved by the fan (in kg/s) divided by the density of this
gas at the fan inlet (in kg/m 3 ).
(2) ‘Compressibility factor’ is a dimensionless number that describes the amount of compressibility that the gas
stream experiences during the test and is calculated as the ratio of the mechanical work done by the fan on the
gas to the work that would be done on an incompressible fluid with the same mass flow, inlet density and
pressure ratio, taking into account the fan pressure as ‘total pressure’ (k p ) or ‘static pressure’ (k ps ).
(3) k ps means compressibility coefficient for the calculation of fan static gas power.
(4) k p means compressibility coefficient for the calculation of fan total gas power.
(5) ‘Final assembly’ means a finished or assembled on-site assembly of a fan that contains all the elements to
convert electric energy into fan gas power without the need to add more parts or components.
(6) ‘Not final assembly’ means an assembly of fan parts, consisting of at least the impeller, which needs one or
more externally supplied components in order to be able to convert electric energy into fan gas power.
(7) ‘Direct drive’ means a driving arrangement for a fan where the impeller is fixed to the motor shaft, either
directly or with a co-axial coupling, and where the impeller speed is identical to the motor’s rotational speed.
(8) ‘Transmission’ means a driving arrangement for a fan which is not ‘direct drive’ as defined above. Such driving
arrangements may include transmissions using a belt-drive, gearbox or slipping coupling.
(9) ‘Low-efficiency drive’ means a transmission using a belt whose width is less than three times the height of the
belt or using some other form of transmission apart from a ‘high-efficiency drive’.
(10) ‘High-efficiency drive’ means a transmission using a belt whose width is at least three times the height of the
belt, a toothed belt or using toothed gears.
2. Measurement
method
For the purposes of compliance and verification of compliance with the requirements of this Regulation,
measurements and calculations must be made using a reliable, accurate and reproducible method, which takes
into account the generally recognised state-of-the-art measurement methods, and whose results are deemed to be
of low uncertainty, including methods set out in documents the reference numbers of which have been published for
that purpose in the Official Journal of the European Union.
3. Calculation
method
The methodology for calculating the energy efficiency of a specific fan is based on the ratio of gas power to electrical
input power to the motor, where fan gas power is the product of gas volume flow rate and pressure difference
across the fan. The pressure is either the static pressure or the total pressure, which is the sum of static and dynamic
pressure depending upon the measurement and efficiency category.
3.1. Where the fan is supplied as a ‘final assembly’, measure the gas power and the electric input power of the fan at its
optimum energy efficiency point:
(a) where the fan does not include a variable speed drive, calculate the overall efficiency using the following
equation:
η e = P u(s) / P e
where:
η e is the overall efficiency;
P u(s) is the fan gas power, determined according to point 3.3, of the fan when it is operating at its optimal energy
efficiency point;
P e is the power measured at the mains input terminals to the motor of the fan when the fan is operating at its
optimal energy efficiency point;

EN
Official Journal of the European Union
6.4.2011
(b) where the fan includes a variable speed drive, calculate the overall efficiency using the following equation:
η e = (P u(s) / P ed ) C c
where:
η e is the overall efficiency;
P u(s) is the fan gas power, determined according to point 3.3, of the fan when it is operating at its optimal energy
efficiency point;
P ed is the power measured at the mains input terminals to the variable speed drive of the fan when the fan is
operating at its optimal energy efficiency point;
C c is a part load compensation factor as follows:
— for a motor with a variable speed drive and P ed ≥ 5 kW, then C c = 1,04,
— for a motor with a variable speed drive and P ed < 5 kW, then C c = – 0,03 ln(P ed ) + 1,088.
3.2. Where the fan is supplied as ‘not final assembly’, the fan overall efficiency is calculated at the impeller’s optimum
energy efficiency point, using the following equation:
η e = η r η m η T C m C c
where:
η e is the overall efficiency;
η r is the fan impeller efficiency according to P u(s) / P a
where:
P u(s) is fan gas power determined at the point of optimal energy efficiency for the impeller and according to point
3.3 below;
P a is the fan shaft power at the point of optimal energy efficiency of the impeller;
η m is the nominal rated motor efficiency in accordance with Regulation (EC) No 640/2009 whenever applicable. If
the motor is not covered by Regulation (EC) No 640/2009 or in case no motor is supplied a default η m is calculated
for the motor using the following values:
— if the recommended electric input power ‘Pe’ is ≥ 0,75 kW,
η m = 0,000278*(x 3 ) – 0,019247*(x 2 ) + 0,104395*x + 0,809761,
where x = Lg (P e ),
and P e is as defined in 3.1(a),
— if the recommended motor input power ‘Pe’ is < 0,75 kW,
η m = 0,1462*ln(P e ) + 0,8381,
and P e is as defined in 3.1(a), where the electric input power Pe recommended by the manufacturer of the fan
should be enough for the fan to reach its optimum energy efficiency point, taking into account losses from
transmission systems if applicable.
η T is the efficiency of the driving arrangement for which the following default values must be used:
— for direct drive η T = 1,0;
— if the transmission is a low-efficiency drive as defined in 1(9) and
— P a ≥ 5 kW, η T = 0,96, or
— 1 kW < P a < 5 kW, η T = 0,0175 * Pa + 0,8725, or
— P a ≤ 1 kW, η T = 0,89,
— if the transmission is a high-efficiency drive as defined in 1(10) and
— P a ≥ 5 kW, η T = 0,98,
— or 1 kW < P a < 5 kW, η T = 0,01 * Pa + 0,93, or
— P a ≤ 1 kW, η T = 0,94.
C m is the compensation factor to account for matching of components = 0,9;
C c is the part load compensation factor:
— for a motor without a variable speed drive C c = 1,0,

— for a motor with a variable speed drive and P ed ≥ 5 kW, then C c = 1,04,
— for a motor with a variable speed drive and P ed < 5 kW, then C c = – 0,03 ln(P ed ) + 1,088.
3.3. The fan gas power, P u(s) (kW), is calculated according to the measurement category test method chosen by the fan
supplier:
(a) where the fan has been measured according to measurement category A, 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 category B, 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 category C, 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 category D, fan gas power P u is used from the
equation P u = q p f k p .
4. Methodology
for
calculating
the
target
energy
efficiency
The target energy efficiency is the energy efficiency a fan from a given fan type must achieve in order to comply
with the requirements set out in this Regulation (expressed in full percentage points). The target energy efficiency is
calculated by efficiency formulas that include the electrical input power P e(d) and the minimum efficiency grade as
defined in Annex I. The complete power range is covered by two formulas: one for fans with an electric input power
from 0,125 kW up to and including 10 kW and the other for fans above 10 kW up to and including 500 kW.
There are three series of fan types for which energy efficiency formulas are developed to reflect the different
characteristics of various fan types:
4.1. The target energy efficiency for axial fans, centrifugal forward curved fans and centrifugal radial bladed fans (axial fan
within) is calculated using the following equations:
Power range P from 0,125 kW to 10 kW Power
range
P
from
10
kW
to
500
kW
η target = 2,74 ln(P) – 6,33 + N
η target = 0,78 ln(P) – 1,88 + N
where the input power P is the electrical input power P e(d) and N is the integer of the energy efficiency grade
required.
4.2. The target energy efficiency for centrifugal backward curved fans without housing, centrifugal backward curved fans
with housing and mixed flow fans is calculated using the following equations:
Power range P from 0,125 kW to 10 kW Power
range
P
from
10
kW
to
500
kW
η target = 4,56 ln(P) – 10,5 + N
η target = 1,1 ln(P) – 2,6 + N
where the input power P is the electrical input power P e(d) and N is the integer of the energy efficiency grade
required.
4.3. The target energy efficiency for cross flow fans is calculated using the following equations:
Power range P from 0,125 kW to 10 kW Power
range
P
from
10
kW
to
500
kW
η target = 1,14 ln(P) – 2,6 + N
η target = N
where the input power P is the electrical input power P e(d) and N is the integer of the energy efficiency grade
required.
5. Applying
the
target
energy
efficiency
The fan overall efficiency η e calculated according to the appropriate method in Section 3 of Annex II must be equal
to or greater than the target value η target set by the efficiency grade to meet the minimum energy efficiency
requirements.
