co2, ac related question

I've been venting out though a carbon filter and vented hoods. I've been wanting to build a sealed room that pulls outside air though the hoods and back out and I want to add co2 via my greenair burner.

My question is... If I'm running an AC in there I'm either ducting it in, or I'm using a portable ac in the room that pulls air out so how is sealed if the ac is pulling air out and If I'm pusing air into the room how do I deal with the positive air pressure in regards to smells?

Thanks,
CT
