I am trying to create an environment where as little if not no new air is introduced and little to no air pushed out. I have a 5x5 tent. After researching portable ac's I found that dual hose ac's use outside air to cool the until and expells the same air out. There is a second intake on the unit that uses the air in the room you want to cool and passes that air through the coils then back in to the room. This should make it so no air is blowing out of the cracks and no air being suckdd in cracks.
When the tent is open there is no real wind blowing and even with no barrier the temps inside the tent are cooler by 8 degrees than air outside the tent. However with the flaps closed the sides of the tent slowly suck in the pull hard so there is negative pressure. I am using 3 air cooled lights. 2 are 8" and 1 is 6". The fan is a max fan 8". When that fan is on the sides suck in even more. The fan sucks air from tent and blows out other side in to tent again so the only thing I can think of is there is restriction from 8" to 6" and the powerful fan sucks more air than is blowing out so air from outside tent is sucked in to compensate? but then where would that "lost air" in the hoods go because there is no where it is blowing out. What am I missing?.
