Bidirectional ventilation unit
(Heat recovery units)
Unit type (non-residential –
Bidirectional)
A distinction is made between ‘A
residential ventilation unit’ that
covers air handling units with air
volumes between 250 and 1000
m
3
/h. and ‘A non-residential ventila-
tion unit’, which covers air handling
units with air volumes higher than
1000 m
3
/h. In SystemairCAD, all air
handling units are categorised as
‘Non-residential ventilation units’.
A bidirectional air handling unit
means a unit which produces an air-
flow between indoors and outdoors
and is equipped with both exhaust
and supply fans.
Fan with multispeed
or var. speed drive
All fans must be equipped with
speed control. All EC motors are
approved automatically, because
they have a frequency regulation.
PM/AC motors can be delivered with
The selection software SystemairCAD is updated with an automatic Ecodesign calculation that will tell you whether the
requirements for both 2016 and 2018 are fulfilled. All calculation details are summarised in the technical documentation.

a frequency converter. The air hand-
ling unit can also be ordered without
any frequency converter and still be
legal to use, but a ‘Warning’ will
appear in the printout. In this case, it
will be the contractor’s responsibility
to ensure that the unit fulfils all
Ecodesign requirements.
Heat recovery
All units must have heat recovery e.g.
rotary heat exchanger, counterflow
exchanger, cross-flow exchanger, or
run-around coil exchangers.
Thermal efficiency of heat
recovery system (HRS)
The actual value and the limit value is
visible from the printout. The limit
value is as follows (dry condition):
Rotary heat exchanger, counterflow
exchanger, and cross-flow exchanger:
2016: 67%
2018: 73%
Run-around coil exchangers:
2016: 63%
2018: 68%.
