@Phil_Bombs Hey man, I think you might find this interesting or informative. It’s regarding window air conditioners and boxing them in so as to be able to use them with ducting (in either configuration; ducting the evap/cold side, ducting the condenser/hot side, or both), but the main principles apply and it helps to illustrate the needs of an ac as far as air supply and exhaust. The second link is to a thread inspired by the first one, where a garage grower rigs up a window ac to circulate his in garage tent’s air, and also to circulate the condenser side with the outside (of his garage).
Portable AC’s are known to be less than ideal, particularly for our use, even more so if trying to use co2.
Anyway, hopefully something in that thread might help or inspire a creative solution or improvement.
I have a window ac I’ve been looking at and thinking “will I cut you, or will I just install you in the window”.
