Some cheap "air con" units do use this effect and yes they do produce
a stream of cool air but as you say the humidity rises. After a few
hours your in cool sauna... and your own perspiration can't evaporate
either so it becomes really uncomfortable.

Anyway AFAICT the OP is referring to a proper aircon unit as the
features specifically mentions dehumidfication of the air, some thing
that only happens with a proper chiller unit.

Still need to dump the waste heat somewhere though. Depending on the
window design a board with a suitably sized hole would do, but really
only works on a sliding type window rather than an opening vent.
