I am growing plants indoor and I need some cooling which I can only achieve with an air-conditioner. Let's also say that I can only use a portable unit. The issue is that I don't want to use single hose portable air conditioner units and don't want want to put the AC unit inside my grow room because 1. the inside humidity is very high and I don't want that to mess up my air-conditioner and vice versa 2. I don't want negative pressure that is so common with portable airconditioners. So I rather want to went the cool air flow into my growing room and keep the portable AC unit outside.
So, I found the below unit but my question is that when this portable AC unit is outside, how is it even going to detect and maintain the inside temperature? Is it just pure marketing or could there be an actual basis to this claim that it can work from outside as well? Because my current understanding is that the AC units detect temperature when the air from the cool room is put outside through the exhaust.
