The horizontal traces are for volume flow level. The downward diagonal lines are for velocity, the upward diagonal strains are for duct diameter.
Even so, the radial damper could be free following a while since it is only secured by a bolt and a nut. Therefore, a number of people prefer to use a crown damper on their own directional diffusers. But, the crown damper is more challenging to regulate from outdoors the diffuser.
Using this technique, it doesn’t issue which diffuser You begin. When you’ve done it, the result need to be comparatively near to the initial airflow you have created on your own drawing.
