Control via an app on smart phone or tablet In the latest event, CO2 sensors monitored the air quality and regulated the
fans. The ceiling fans provided the air circulation. For the duration of the event, the CO2 level in the indoor airwasmaintained at approximately 530ppm. “That equates to almost the same as fresh air,” says Dr Gordon, referring to a study by the TU Berlin,which considers lowCO2 values to be harmless (Risk assessment by the TU Berlin:

fromZiehl-Abegg (ZN063-ZIL. DG. V7P2), four HVLS ceiling fans (high volume lowspeed), eight CO2 sensors and a standardised IP-based home control systemfromLOxonewith control software fromSmartflix.
The volume of air in the hall is approximately 16,500 cubic metres. Each of Ziehl-Abegg’s built-in axial fans moves up to 6,000 cubic metres of air per hour. Three fans are used for suction and five for the inlet air. This allows the entire air content of the large building to be completely replaced up to twice an hour.
