Why air flow created by ceiling fan (which rotates counter clockwise (seen from beneath ceilling) ) goes downward?

You got me thinking about that one. The reason, I think, is quite simple. A standard motor runs 'clockwise' and, if it is suspended with the shaft pointing downwards then the fan blades need to push away - which is the opposite way that most screws are operated. They wouldn't want to make a special set of motors for ceiling fans, would they?CWatters said:Incidentally if you compare the blade pitch with the thread on a standard screw they are have oposite "hands". In other words a ceiling fan is similar to a screw with a left hand thread not the normal right hand thread.

The direction of the air flow from a ceiling fan is determined by the orientation of the fan blades. The angle of the blades causes the air to move in a downward direction.
In order to achieve downward air flow, the ceiling fan should rotate counterclockwise. This pushes the air downwards and creates a cooling effect.
The direction of the ceiling fan blades determines the direction of the air flow. When the blades are angled in a downward position, the air is pushed downwards, creating a cooling effect. When the blades are angled in an upward position, the air is pulled upwards, creating a warming effect.
Having the ceiling fan blades angled in a downward position helps to create a wind chill effect, making the room feel cooler. This is because the air moving across our skin helps to evaporate moisture from our skin, making us feel cooler.
Yes, the direction of the ceiling fan blades can be changed for different seasons. In the summer, the blades should be angled in a downward position for cooling, while in the winter, the blades should be angled in an upward position to help circulate warm air that rises to the ceiling.
