Most aircons generate not just hot air, but hot very wet air, to the
point where a lot pf it drips around the place..if the tube goes
straight up, chances are it will run back down the tube into the unit.

Of course that depends a lot on the exact unit, which is unspecified.


How does it make the air wetter than it already is?

By effectively drying the bit that it is cooling.

It does depend on the type of aircon. If it condenses water out to a
tank or a drain the exhaust air will be no wetter than ambient. If
however it is the type that evaporates off the condensate then the
exhaust will be wet.

Yup. But some air somewhere gets wetter, and some air somewhere gets
drier :-)
