Fan Direction For Ceiling Mounted Living Room Circulating Fans ?
 

Hello:

Moved into a house with a fairly large living room that has a high
(essentially two story)
ceiling.

Air circulating type of ceiling fans mounted from ceiling, which appear to
be reversible, and variable speed (presently set for a very low speed).

Also, there are A/C ducts up there from an attic mounted, split A/C type of
system.

Realize that hot air rises, and the cooler air conditioned air will tend to
sink, and, will of course experiment to see what works best, but was
wondering:

In the summer, with the A/C Off, is it "best" to run the fan in a direction
that moves the
air downward ?

How about with the ceiling A/C running ?

And, what direction best for the winter with the heat on ?

Thanks,
Bob

Yes.

Still down.

Allegedly up, but YMMV. In summer you want to feel a little breeze as it
makes you feel cooler. In winter you don't want that so just using a very
low speed may give the results you want and no draft.

Up in winter. The idea is to push the warm air toward the floor, but by
pushing air into the ceiling first, it spreads out along all the wall length
before dropping, thereby minimizing drafts.

Yes, down in Summer

Still down

UP, will force the air (heat) up and out to the walls and down

All good advise, founded on scientific facts.
To assure domestic tranquility, turn the fans the way your wife wants them.
I have to stand on a stool to pull the slide switch down but my wife can
simply push it up with a broomstick. Unless she is having one of those day,
when nothing is cool enough.

Either way will work. If it blows up, the air goes up in the center
and down along the walls. If it blows down, then it will blow down in
the center and up along the walls. If you are right under the fan, you
will feel it more when blowing down. Then use down in the summer and
up in the winter. Asking your wife is always a good idea, if Mamma
ain't happy, ain't nobody happy. :-)

The room is essentially a closed system, the air circulates either way.
Do what feels best to you, it is YOUR comfort that matters. Furniture
placement and where You and Momma sit has a lot to do with it.

If you don't have one. next time you are at a hardware store, get a
wooden yardstick. Drill about a 3/8" hole at one end to hang it
somewhere accessible. When needed, use the yardstick hole to grab the
switch and pull it down.
Alternative: Screw a cup hook or something similar in the end of the
broomstick

Don't know why fan blades are not vertical. Changed mine and like the
performance better.

I wondered about doing that. Certainly can shift more air, but its also
putting a lot more load on the fan motor.

I don't think it does or at least it isn't apparent. Of course it isn't
the thing for fans hung low under a high ceiling but where the fan must be
up near a low ceiling it makes sense.

Changing the pitch on a propellor fan blade to a steeper angle
increases the load on the motor. Either the motor will trip on
overload or it will burn out. Unless the motor is oversized in the
first place.
