HVAC system control in a cleanroom
Downdraft air flow control in a cleanroom is very delicate and challenging to adjust. Flow simulation is a key to reducing the time needed to adjustment the air flow.
Contaminated material is emitted from the work station in a vertical laminar flow cleanroom. Normally the opening ratio at the floor is adjusted through a trial and error process to facilitate the vertical exhaust near the wall. This can be a tedious and tim consuming process. Simulation can provide insight about how the floor opening ratio should be adjusted to produce the desired downdrafts.
