So my question is WHICH way is this !@#$#@ system

designed for? UP or DOWN air in the summer?



it depends if you have air conditioning.



again which way? for what reason? elaborate?



heat rises. If you have ac, you want to push the warm air

down so it can become ac'd. If you don't have ac, you might

as well leave the warm air up there were it will be less

noticed.



But you can cool to a higher temperature if you help the

convection off your skin. Add in evaporative cooling and a

breeze is a big win, at least in small rooms, like a home.



We have air conditioning which keeps the house at 78, and a way

undersized room dehumidifier which we set up in the master shower,

turn on the circulating fan in the furnace, and basically slowly

and inefficiently dry out the whole house.



It makes a huge huge difference how hot it feels -- and we're in

Oregon,

where everyone is a humidity wimp.



Do you realize the dehumidifier is just an AC unit where the heat is

exhausted back into the room? You could do the same thing by

running a small space heater which would make the AC run more often

which does a much better job of taking the humidity out of the air.

Actually, I've never seen a house with AC that still had high

humidity, but then I'm not in the Pacific northwest.



Our AC is a heat pump which does not remove the moisture from the air

-- it just cools it. Don't ask me how -- for all I know they have the

thing arranged to do it on purpose.

Any heat pump or other air conditioner WILL remove humidity from the

air - warm humid air passes over cool surface, humidity condenses out.

Cannot be done any other way.



Water does not dribble out of it, and even when it is going the

dehumidifier will remove gallons from this place in a day.



Water doesn't dribble out of it because there is a drain line from the air

handler to the outside. It doesn't remove ALL the water vapor...how much

depends upon air temperature and humidity.

I'm with you and Cl on this one. The physics of every AC says that when
you cool humid air, water condenses out. That water either has to go
out a drain line, dribble out, or else get deliberately put back into the
air, by reheating it somehow, like a hot pan. In the case of a residential
heat pump system, it would almost certainly be a drain line.

A make and model of the heat pump would settle it or perhaps a pic.
