At the local votech they are doing some changing. They are moving 3-4 blueprint plotters into this room. They also have one of them plastic prototype machines (not 100% sure how it works, but it looks cool!).
Anyway, this room is 20'x20', about 8.5' tall. Obviously the stink will be great in there, and they are worried about that. They don't know what they want, they just want something, and cheap. My 1st thing to say was talk to an engineer about this, as they can figure everything up "properly (hopefully)", and sign off on it to eliminate any problems down the road. They don't want to... that's our job I guess.
I'm not real sure what to do here.... I would guess that 300-500 CFM might be enough, but likely on the small side. Not to mention there's no real good place for make up air. The 2 walls into the hallway are fire rated, so a fire damper would be required (or a fire rated grill?). The other 2 walls are into other rooms, and we can't transfer there because they aren't near big enough either.
Could bring it in from the roof (where the exhaust is going out), but then we'd have to heat it too, well to do it right anyway.
I kinda thought of a HRV, but there's no possible place to put the cond drain into for at least 50' or more (plus numerous fire walls).
Every good option I can think of to do this right will involve at least a couple grand, but likely much more than that... and I have a good feeling they'll throw our bid out (not always a bad thing).
So, what would you guys do?
