The ideal goal is to exchange the air 6 times per hour. That's a lot of air. I'll be luck to get four exchanges through my room every hour, with 2x 6" flex duct supplies and 1 8" flex duct return. (2300 cuft)
Gotcha - I'm gonna start with 2 vents both 8" and each with its own fan. What are your opinions on the following options regarding placement?(especially options 4 ,5)
- (1) 8" supply on the front wall and (1) 8" return on the rear wall. Being that I'm planning/hoping for just these 2 - should they be at opposite corners of the room? i.e. see revised diagram below (red "x" = location of vents - pretty much the only spots that I have access to). One is in the front - right corner, the other about 3' from the right wall (total room width about 12') - will that also circulate the air near the right wall of the room?
OR since I'm going to put a fan in each vent - can I put both supply and return vents side by side on the same wall (as less work and can put both ducts in the same dead vent)?
OR Can should I put the return vent below the projector(see 2nd diagram)
Option 4 (makes most sense to me)
OR What if I put the return vent facing the projector - in this way I can close off the projector soffit when watching a movie (noise is distracting somewhat), and if I close the bottom of the soffit with something slideable - I an keep it open the rest of the time, to allow the air from the room to flow in see 3rd pic below for actual photo (actually come to think of it, how do people make a hush box, and let air in?
OR Option 5 -
put the return vent next to projector (as in option 4) and supply vent in front wall corner (as in option 1). Or will the 8" fan be wayyy too strong for the projector
Option 3 (and 4)
