[bldg-sim] VAV control of underfloor air

["Molinini, Louis" <lmolinini@xxxxxxxxx>]

Do any of you out there have any experience designing an underfloor air
system with VAV control.  The particular system I am looking at is a plenum
based system with manually adjustable swirl diffusers (Titus/Krantz).  I am
curious if it ends up operating like a constant volume system or is it worth
the expense of installing the freq drive and the Static pressure sensor or
differential pressure sensor.  Any help is greatly appreciated.
Thanks,
Louis
