I’ve worked places that used a lot of portables and I’d rather use a window banger than a portable bcuz of the loss of floor space, the hose issues and the drain pan vigil. I’d much rather rig a window and have a removable window unit than for those flex hoses. Storage and setup would also be better. I’ve done enough AC service in the south to know how brutal the latent load is… just getting the wet bulb down is heavenly.
They’re a thing of the past but I put in Cold Wave water cooled refrigerated spot coolers in the 70s. They cooled GREAT bcuz they used one-pass water, super net output, but wasting water like that would get you in trouble, now. Craig
