That’s only partially true. The evaporator is located on the indoor unit, and that’s the part that gets cold and generates all the condensation. There is a drain hose on the indoor unit that has to be directed outside, and the condensate water will only flow downhill. Up is not an option. This is what makes installing a mini split on an interior wall such a hassle.
So that’s why I’m wondering why the lineset cover goes up in that picture. I guess it’s possible there is another hole punched in the wall behind the unit for the condensate line, which is the normal way to do it. But I have absolutely no idea why, if there is exterior access like that, anyone would not also run the rest of the lineset through the same hole…
Not to mention I don’t see a way to check the drain pan from the inside. That set up makes me nervous. I’ve got three registers in my house and I check the pan every time I clean the filters. No way I want to deal with an indoor leak.
Idk how common it is but where I used to work had a split system where for some reason the evaporator unit was also outside like a standard AC unit and then cold air was ducted in and pumped out of one of those boxes

Well, it is, but then you need a pump.

The squareness of the duct made me think of that
