How A Ceiling Fan Works
There's nothing better than getting home from work on a sweltering afternoon, switching on the ceiling fan, and relaxing in comfort with that fan passing over your head, cooling down your hot, stressful day. Ceiling fans can make life a great deal more comfortable, and they can save money on cooling bills as well. In fact, if you've got good ceiling fans in a few rooms of your house, you probably don't even need an expensive, bulky air conditioning unit. More than likely, you've thought about how great ceiling fans can be. Not only do they cool down rooms, but a beautiful ceiling fan in the right style and color can change the entire ambience of a room. A ceiling fan is defined as a mechanical fan, usually electrically powered, that is suspended from the ceiling of a room that uses rotating paddles to circulate air. But does that really explain what a happens in a ceiling fan that brings so much comfort to life? How do these great mechanisms work?
History of ceiling fans
Ceiling fans have been around in the U.S. since the late 1800s. Just as with air conditioning, water was the means of powering the first known ceiling fans. This was used along with a turbine, and the whole thing worked together to drive a system of belts that turned blades. This action pushed the air around, thereby cooling a room. The first ceiling fan that was powered by electronic parts was invented in 1882 (and later patented in 1887) by mechanical engineer Philip Diehl, who was a contemporary of Thomas Edison. This device was a fan blade mounted on a sewing machine motor and attached to the ceiling. Diehl later added a light fixture.
