That depends on what you're trying to do with the air Shambav. If
you are meeting outdoor air requirements to maintain Indoor air
quality then refer to ASHRAE 62.1. If you are attempting to
condition the space (heat or cool) with the air then volume flow<br>
<br>
V = Q / rho.Cp.deltaT<br>
<br>
where Q = Heating / Cooling rate, Rho = density of air, Cp =
specific heat, DeltaT = difference in room air temperature and off
coil.<br>
<br>
A VAV system does both of these (supplies outdoor air and room
conditioning) and uses a mixing box.<br>
<br>
If you want to understand VAV get hold of <a
