It is essential that the duct collar to the plenum box of linear slot diffusers is place on the aspect on the plenum box as opposed to on the top.
As soon as you’ve calculated the airflow of all diffusers, Look at and find out In case the airflow on Every diffuser makes sense. Request concerns like:
The computer rack has 4 enthusiasts from the roof but provides a dispersion address over that.
