Functional description
Decentralised supply and extract air units for room ventilation and for dissipating cooling loads and heat loads.
An EC centrifugal fan takes in the fresh air which then flows through the motorised shut-off damper and the F7 filter.
Once the fresh air has passed the fan, it flows through the recuperative heat exchanger for heat recovery; it is possible to bypass the heat exchanger in order to pect it, or when it is sensible with regard to energy efficiency.
If necessary, the air is heated or cooled by the heat exchanger before it is discharged to the room as a displacement flow.
The extract air first passes a G3 filter (that pects the unit), then flows through the heat exchanger (for heat recovery), the extract air fan and the motorised shut-off damper before it is discharged to the outside as exhaust air.
Automatic switching to secondary air mode (only with an air quality sensor) if the room air quality is sufficient.
The fresh air damper closes, the self-powered secondary air damper opens and the extract air fan is switched off.
The unit always starts in secondary air mode, which is more energy efficient.
