CEILING FANS
[CODE 3402]
A ceiling fan is a device suspended from the ceiling of a room, with hub-mounted rotating blades that circulate the air, thereby producing a cooling or destratification effect. Most ceiling fans have an electrical switch that allows one to reverse the direction of rotation of the blades.
Principle behind the Ceiling Fan
The electric motor is the electric machine within the ceiling fan that converts electrical energy into mechanical energy. The ceiling fan capacitor torques up the electric motor, allowing it to start and run. An electrical current reaches the motor and then enters coils of wire that are wrapped around a metal base. As this current passes through the wire, a magnetic field is caused that expends force in a clockwise motion that actually changes the electric energy into mechanical energy. This action causes the motor coils to spin. As the coils are spinning, the fan captures this spinning motion, transferring it to the fan blades.
How the Ceiling Fan Cools
Fans do not actually cool air (if anything, electric fans warm it slightly due to the warming of their motors), but the breeze created by a ceiling fan speeds the evaporation of sweat on human skin, which makes the body feel cool. Thus, fans may become ineffective at cooling the body if the surrounding air is near body temperature and contains high humidity.
Ceiling fans are very commonly used for circulation of air in a room to bring the cooling purpose easier. Due to circulation of air in a room, the cooling rate increases and we feel cool and less safiocation. When the air is circulated, air comes from other place and due to this the room becomes cool.
