Nonetheless, they aren't capable of throw air in terms of linear slot diffusers Considering that the air will not be concentrated. Even so, double deflection diffusers remain ideal for most higher ceilings the place the ceiling height is about 9-12 meters.
Therefore, you’ll do the recording, locate the patterns and notify your helper the amount of the damper needs to be closed. Take into account that the airflow measurement work is exhausting. So, consider to not question your helper to shut and open up precisely the same damper as well usually.
