I am attempting to use a window A/C unit to cool my 4-1/2'W x 8'L x 6'H tent. What I want to do is build a compartmented box that will take the place of the front cover of the A/C. Then run two 6" ducts to the tent. Clearly, the built in fan in the A/C is not going to be strong enough. After looking inside the A/C, I can see that it is poorly sealed. I need to keep the pressure from a booster fan neutral to ambient pressure. My thought is to use two fans, one (with a carbon filter) pulling air from the tent and pushing to the A/C, the other pulling from the A/C and pushing to to tent. I am hoping that, if I run both fans off the same speed controller, the two fans will move an equal amount of air, thus NOT pulling outside air in or out of the system. Can one run two fans off the same controller? Has anyone tried ducting a remote window A/C this way? The two fans are identical. I have a complete co2 system (tank, pressure regulator with flow meter, and CAP PPM-4 controller) I intend to use. The evaporator coil must remain open at the bottom for condensate to drain, otherwise I'd just use spray foam to seal everything up.
Any advise or input would be appreciated.
