Which direction for your ceiling fan?

Which direction should your fan blow and why and should it ever change and when and why?

Also provide diagrams, equations and experiments to prove your reasoning.

 

CCW for summer I believe.

 

Depends on the season

 

Do you mean an African or a European swallow?

 

I'd draw you a picture but you ate all my crayons.

 

General consensus is blowing down in the summer, up in the winter.

 

Blow up.

Like your dolls.

 

Doesn't make it correct.

 

The thought is that moving air feel cooler. If you blow the warm air down, it feels cooler than it is, which is good in the summer. In the winter, you suck the cold air up, it disperses and and warms, then drifts down slowly

 

Hugger or not??

 

You're half right!

 

For like my family room, 18 ft ceiling, fan hangs on 4'6" rod.
In the winter pushing up pushes the warmer air down the walls, which also helps on the walls to the outside, etc.
ONe thing for sure, a moving ceiling fan collects way more dust than one that don't move.

 

I really don’t know. I do know that a long time ago I rented this old house that had this goofy radiant type heater in the floor in the middle of the house where the living room and dining room came together. It was literally a big gas fired burner under a 4’x4’ grate in the floor. The house also had 10ft ceilings. I could never get it warm in there until one day I thought to turn on the ceiling fan. Even with them blowing done, it was much more comfortable in there.

 

When I had a live-in girlfriend, we had ceiling fans installed in most of the house. Now that she is out of the picture, the ceiling fans are off. The constant wind in my face was playing havoc with my contact lenses.

 

Stratification of temperature gradients, aka Thermoclines. Moving fluids mix and become isotropic, calm fluids stratify. Cold on the bottom, warm on the top. Just like any body of water, or our atmosphere.

 

In the summer, you want it pulling up so it pulls cooler (heavier air) up off the floor. In the Winter, you want to blow the rising hot air back down.

 

While that sounds plausible, I think that's the opposite of the general instructions.

However- one can blow it any direction they want to though

 

Just turn the damn thing on. As long as it’s circulating air, zero $hits are given about actual direction.

 

Mine just spins in circles.

 

Up draft winter.
Down draft Sumer.

Yes, I think you’re ghey. LOL.
