Whats going on everyone! So, I got a room that about 2000 sq ft. It has two rooftop AC units that have the return air duct in the room. I was told that the return air is pulled and goes in a circle and right back in the room meaning the air in the room is the same. Basically, I am running CO2 in this room and ran through a 20lb tank in 24 hours. Obviously, the air being pulled out of the room is going outside somehow because the tank didn't last at all. Is the return air really pulling out of the room and dumping the same air in? If so why am I losing all the co2?
