How Does An Electric Ceiling Fan Work

How Does an Electric Ceiling Fan Work?


Structure








The ceiling fan is a motorized cooling system. It's sort of like a propeller that pushes at air in a consistent movement to create a draft or breeze inside of a room. The fan has two important components that create a cooling or warming effect: a central, mechanized motor and long, flat blades that revolve once the motor is in operation. The blades are attached to the motor, usually at an angle that is at the vertical axis of the motor. The blades can move clockwise or counterclockwise, depending on the function it performs. Though ceiling fans are normally used during hot days to cool rooms, they can also be used during the winter to evenly distribute warm air.


Function


A ceiling fan works using a dynamic of movement. Warm air generally rises toward the ceiling. When it isn't circulated, the air stays trapped in the room, thus heating it. The air must be consistently circulated, pushing the hot air out of the room to create space for cooler air. The ceiling fan does this by pushing the air back down through constant movement, which affects the surface of the air produced by breezes.


When the motor is in operation, it turns the blades in varying speeds, depending on how much of a cooling or warming effect is needed. As the blades turn, they gather air--which is then pushed by the leading edge of the blades. This movement forces the air onto the trailing edge, creating a front-to-back movement that produces a breeze.


Effect


Once the blades accelerate, they distribute warm or cool air in the room, keeping a steady and even temperature. Installing a fan too close to the ceiling will prevent a proper draft from being created. The warm air has to rise to the ceiling before it can be pushed back down by the spinning blades, so a proper amount of space must be established between the fan and the ceiling.


Ceiling fans don't reduce temperatures, but they do circulate cool or warm air in such a way that it creates a cooling or warming effect or a breeze. Other heating or cooling systems, such as electrical heaters, radiators and air conditioners, affect the temperature of a room. But ceiling fans are highly effective when used along with these other systems to cool or warm a room by pushing or trapping the air and distributing it throughout.
