When I researched this, I found direction is not so important other than comfort purposes. The fan will setup a recirculation, so when pushing air down, there will be other (slower) air moving up all around the periphery. And when pulling air up, there will be downward (slower) flow around the periphery.
Generally, the notion is to use downward flow in summer for a cooling effect, as people will feel the higher speed flow moving down over them and perceive a cooling effect. And in winter, use upward flow so as to not create a cooling effect. Other than those considerations, you can run in any direction you want and the fan will recirculate and mix the room air.
Yep. I find that if I have it in the up direction, it moves the warm air out from the center of the ceiling evenly in all directions, down the walls, and some of it goes out of the room under the doorways into the other rooms. If I run it down, the warm air comes down in the center of the room and spreads out from the center of the floor, IF the room had no furniture. The furniture seems to disrupt the flow of the air out of the room. Also, its in our dining room, so we don't want a breeze down on our food! :licking:
Anyhow, I can raise the temps in the adjoining rooms several degrees by turning on the ceiling fan. Very noticeable. :thumbsup:
