Air mixer

Air mixer box present

 BS EPG
In this box it can be specified whether air mixing, or recirculation, is applied in the system. The recirculation is only taken into account in the energy performance calculation EPG if these calculations are performed based on the actual installed ventilation power. This means that the recirculation is not taken into account for air flows according to the minimum ventilation requirements.

Minimum outside air

[%] BS EPG
If air mixing is applied, the percentage of supply air which consists of fresh outside air (not recycled air) can be specified in this field. The remaining supply air will be extracted from exhaust air. The fraction of fresh outside air should comply with the minimum ventilation requirements for the energy performance calculation EPG.

If outside air temperature <

 BS
The maximum outside temperature below which the outside air is allowed to be mixed with recirculation air is specified here.
