<P>If the FC <U>recirculates</U> the air where does the room side VAV come into picture? Typically for high-rise residential, there is a CAV supply of tempered air @ 63F with the individual FCU's doing the comfort conditioning. The kitchen /bathroom exhaust runs continuously to meet ASHRAE 62.2<BR><BR>Can you provide some more detail about your systems?</P>
<P> I am currently working on a model with above mentioned conditions and we should compare notes.</P>
