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.

If the AC is oversized it is not efficient at removing humidity

because it doesn't run long enough. ANd if it isn't warm enough to

require running the AC, you still have the humidity.



Don't you just turn it up until you get to a combination of

temperature/humidity that feels comfortable?





Which is better, hot and humid or cold and clammy??? If those are your

only options, you are never comfortable. You need to be able to dry

the air at both ends of the scale.





Why are those two your only options? Like Brian, I have no problem
setting a comfortable temperature. If it's too humid, I've never
had conditions where lowering the thermostat 2 degrees didn't fix
it and result in a comfortable temperature. If it's 80+ and humid
outside, the AC runs enough so that humidity isn't a problem. If
it's cooler and the AC isn't running, lowering it a degree or two
to run the AC for a bit lowers both the humidity and the temp and
it's comfortable, because it's the combined effect that we feel.
You must live in some unusual conditions.
