how to size fan and louver combination
(OP)
i have a 15' x 18' room with a 10 tall ceiling which will have two 75 hp blowers (only one on at a time) and two 10 hp smaller blowers. i am trying to size a fan louver combination to dispense with the heat. any suggestions?





RE: how to size fan and louver combination
Is there an adjacent building with air intakes nearby?
Is this at grade level?
Are there any air intakes in the same building nearby?
What type building is this?
What effluents are in the airstream?

Q = 1.08 CFM * Delta T
Q = heat gain in Btu/hr
Delta T = 104°F - OA Temp
(if OA temp exceeds 104°F you may require mechanical cooling)
Once CFM is determined size your louvre for pressure drop and water penetration. Size your fan on CFM and pressure drop.
Some details of your situation would have to be implemented in any of the calculations. The above is a very general description.

On the short side, it's closer to 500 fpm, so you might forget the walls and just build louvers, instead - on both ends.
Interesting. Yes, please tell us what it's about.
