Ventilation Duct
To ensure ventilation and air conditioning systems function perfectly, the volumetric flows must be correctly set across the whole system. The volumetric flow along with the air velocity must therefore be measured according to EN 12599 and EN 16211. Observance of air flows in the ventilation duct is of utmost importance. If the air flows are smaller than intended, the removal of room loads (heating, cooling and substance loads) may not be ensured in certain circumstances. Therefore, the most accurate recording of air flows as possible is particularly important.
