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.
