6.19 Installation of pipe system on forced air
flow monitoring
A forced air flow means the use of ventilating and air-conditioning units.
Special pipe project planning must be observed for the monitoring of the
ventilation or air conditioning ducts (see chapter "Project planning with
forced air flow").
6.19.1 Detection of supply and exhaust air openings
If air is sampled in forced air flows (e.g. by means of ventilation or air
conditioning systems), the aspiration apertures must be aligned with the air
flow. Position the aspiration apertures as shown below:
exhaust airflow speed
< 1.64 ft/s
> 1.64 ft/s
