Objective
There are various fan driving systems with different energy efficiency characteristics available for
HVAC units. In order to measure the energy efficiency of two fan driving systems, they have been
subjected to specific set-up and operation conditions of HVAC units.
The following fan driving systems have been assessed:
•
Permanent magnet motor (PM) in standard motor shape with frequency inverter
•
Electronically commutated motor (EC) - combined fan/motor unit

Test rig
2.1
Set-up of the test rig
The measurements have been carried out at the suction side of a chamber test rig according to
DIN EN ISO 5801[1]. The major components of the test rig have been the air flow rate
measurement system with its approach and outflow zones, the pressure-controlled support
ventilator, the throttle, and the flow rectifiers and conditioners. The test rig consists of a chamber
with a clearance of 1,400 mm x 1,600 mm and therefore allows for fan characteristics
measurements with air flow rates between 11 m3/h and 11,000 m3/h and chamber pressures of up
to ± 5 kPa. The maximum uncertainties of air flow rate and chamber pressure are 1 % and 0.3 %
both of the measured values, respectively. The set-up of the test rig is illustrated in Figure 1.

Schema of the test rig
Test assembly
The influence of different fan driving systems is to be tested for specific set-up and operation
conditions of HVAC units. Due to the influence of the walls of the fan casing on both the fan and
energy efficiency characteristics, the fan has been installed into an HVAC unit casing. In order to
reduce the influence of inlet and outlet, both approach and outflow zones have been installed.
Moreover, a perforated plate with an open area of 35 % has been inserted in the approach zone.
This test assembly ensures HVAC system specific set-up conditions for the measurements (see
Figure 2 and Figure 3).

Sample 1 – centrifugal fan with EC motor
The reference unit for the efficiency measurements is a fan unit produced by ebm-papst (type
R3G400-XX23-YF), which is a prototype or a model in a pilot lot. The fan unit comprises also the
drive and the speed control. For illustrations see Figure 6 and Figure 7.

Sample 2 – centrifugal fan with PM motor
The reference unit for the efficiency measurements is a fan unit produces by ALKO (type RLM E60400). The fan is was driven by a permanent magnet motor by Lafert and power supplied by a
frequency inverter of Danfoss/VLT. For illustrations see Figure 8 and technical data see Figure 9,
Figure 10, and Figure 11.

Measurements
The measurements have been carried out at the suction side of a chamber test rig according to
DIN EN ISO 5801[1] as illustrated on page 6. All samples have been operated for at least six
hours in order to reduce the influence of potentially unused bearings. Test series have been
carried out for each of the samples in the range of nominal number of revolutions per minute and
2 % of the nominal motor power. Each of the measured point in the characteristics has been
obtained in steady state conditions, ensuring standard deviations of both the air flow rate and the
ILK-B-31-15-3981en

test pressure below 0.3 %. Due to thermal influences, each measurement cycle of a
characteristics line required more than one hour. The maximum system efficiencies are provided
in Table 1.

Fan characteristics R3G400-XX23-YF (Sample 1)
The maxima of the efficiency provided in Table 1 are illustrated in Figure 13. It can be observed
that the EC fan unit (R3G400-XX23-YF, sample 1) has the largest system efficiency. The
difference of the efficiencies at nominal operating conditions of HVAC units is about 3 % to 4 %.
Especially in modern air handling and conditioning units it is possible to adjust the air flow rate
according to the demand, leading to part-load ratios of approx. 10 % for many operation hours
during one year. The system efficiency of the EC fan unit is approx. 55 % for this particular partload stage, whereas the PM fan unit with standard shape motor and frequency inverter has
system efficiency of approx. 51 %.
