The superior velocity in the primary duct that is brought on by the sharp turns and sudden bends, minimizes the move in to the 3 branches about the remaining.
If I near the doorway to RM1 through the stairwell (reverse facet of windows), the temp rises to 32deg overnight. If I open up the door, it drops back again to 24deg. I installed a 150mm inline duct supporter in RM1 which has a rating of 540m3/h.
So, I generally evaluate all current diffusers and history their airflow previous to adjusting and good-tuning more info their damper for that air balancing work and it should be an exceptionally speedy endeavor.
