4 Functions
A multifunctional ventilation unit provides ventilation for single dwelling as a leading function. This
means, that all additional functions:
— hydronic heating/air heating;
— hydronic cooling/air cooling;
— hot water production;
shall be operating only when ventilation is operating.
The multifunctional ventilation unit shall be designed and controlled to provide the hygienic ventilation
rate for a dwelling or part of a dwelling. That means for example, that the ventilation rate shall not be
controlled according to the hydronic heating demand.
If specified by the manufacturer, the unit may use an additional outdoor air volume flow, to provide a
higher thermal capacity if needed. This leads to two alternatives:
1) The higher outdoor air volume flow (outdoor exhaust air) does not affect the ventilation function
(fresh air and removed air).
Additional tests shall be performed according to the declaration of manufacturer. No further
correction needed
2) The air volume flows for ventilation (fresh air and/or removed air) increase. In this case the air
volume flows shall be measured and documented as a percentage of reference air volume flow.
NOTE This may be needed to allow a correction of system performance according to the EPBD calculation.
5 Description and testing of multifunctional units
Table 1 shows a non-exhaustive list of relevant combinations of multifunctional units with the
corresponding applicable test procedures according to Clause 6, 7 and 8 for thermal and acoustic
performance.
The leading function is ventilation at reference air volume flow. The heat pump can use any air source:
outdoor air, exhaust air, recirculation air or any mixture of these.
For testing the unit shall be installed according to the manufacturer instructions given in the
installation manuals unless otherwise specified in the referred standards for specific tests.

Foreword
This document (prEN 16573:2013) has been prepared by Technical Committee CEN/TC 156 “Ventilation for
buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
1 Scope
This Standard specifies the laboratory test methods and test requirements for aerodynamic, energy rating and
acoustic performance, of multifunctional balanced units intended for use in a single dwelling.

complete package with the mount instructions.
It covers unit that contain at least, within one or more casing:
 supply and exhaust air fans;
 air filters
 common control system.
And one or more of the additional components

4 Functions
A multifunctional ventilation unit provides ventilation for single dwelling as a leading function. This means, that
all additional functions
• Hydronic Heating/Air Heating
• Hydronic Cooling/Air Cooling
• Hot water production
shall be only operating if ventilation is operating.
The multifunctional ventilation unit shall be designed and controlled to provide the hygienic ventilation rate for
a dwelling or part of a dwelling. That means for example, that the ventilation rate shall not be controlled
according to the hydronic heating demand.
According to the declaration of the manufacturer, the unit can use an additional outdoor air volume flow, to
provide a higher thermal capacity if needed.
1. The higher outdoor air volume flow does not affect the ventilation function (fresh air volume ventilation
flow and balance of the fresh air volume flow for the dwelling).
Additional tests shall be performed according to the declaration of manufacturer. No further correction
needed
2. The air volume flows for ventilation increase. In this case the air volume flows shall be measured and
documented as a percentage of reference air volume flow.
NOTE This may be needed to allow a correction of system performance according to the EPBD calculation.
5 Description of multifunctional units
Table 1 shows a non-exhaustive list of relevant combinations of multifunctional units with the corresponding
applicable test procedures according to clause 7 and 8 for thermal and acoustic performance.
The leading function is ventilation at reference air volume flow. The heat pump can use any air source:
outdoor air, exhaust air, recirculation air or any mixture.

6 Performance testing of aerodynamic characteristics
6.1 Leakages
6.1.1 Test method
Pressure testing method applies to classify leakages of the unit as defined in Annex B of EN 13141-7.
For internal leakage, if the pressure method is not applicable, e.g. units using recirculation air, the unit shall be
tested as category 2 heat exchanger (tracer gas method).
6.1.2 Requirements
To set the declared maximum air volume flow, the declared total pressure shall correspond to 100 Pa, or to a
lower total pressure if the intended use declared by the manufacturer is less than 100 Pa.
The declared maximum air volume flow shall be equal to the smaller in case the supply and extract air volume
flows are different.
In addition, to assess correctly the thermal performance, aerodynamic characteristics, shall be tested before
or together with any thermal characteristics testing.
Aerodynamic characteristics shall include:
 external leakage or total recirculated fraction in supply air;
 internal leakage or recirculated fraction from extract to supply air or total recirculated fraction in
supply air.
The tests for air flow/pressure curve and thermal performances shall not be made because of measurement
uncertainty when leakages according to 6.1.1 are too high. The external and internal leakage of the unit shall
comply with Class A1 or A2, B1 or B2, C1 or C2 depending on
