Linear slot diffusers required a rectangular-formed plenum box having an opposed-blade damper for airflow Manage. The plenum box features a round duct collar for a versatile duct connection.
We can easily see through the velocity colour scale and also the streamlines that inside the design around the still left, the inlet air immediately strikes the sharp turns that happen to be existing within the system which causes a rise in the static strain.
Double deflection diffusers are typically utilised in school halls, small-conclude theatres and auditoriums exactly where you will find superior ceilings and aesthetics is just not a major problem.
