So my question is WHICH way is this !@#$#@ system designed for? UP or DOWN

air in the summer?



If your room is a well insulated adiabatic system, it doesn't matter.

The fan just mixes the air until the air in the room is all the same

temperature. Whether you mix from the bottom or top has little effect

on the final temperature.



It does matter because blowing down you typically get a breeze blowing
down on you, which has a cooling effect, especially in summer, when
you're going to sweat more.
