Abstract
For air distribution or extraction, fan speed is controlled using modeling to account for venturi air valves. A minimum pressure for each venturi air valve is incorporated into the model. The pressure losses for various duct airpaths to terminal units is calculated based, in part, on the minimum pressure of any venturi valve. The fan set point or operation is established based on the highest needed pressure in the various airpaths connected with the fan.
