Ceiling Fan

Hello readers. A hot and sultry Sunday evening in Chennai prompts to me to write about “Ceiling Fans”.

Digging up some information from Wikipedia I am made to believe that ceiling fan is an American invention. I am not sure about this yet.

Fans (as known widely) are electrical appliances which are used to circulate air within a room. If the temperatures are not too high and if the humidity is in check, fans do their job well of cooling the room.

These appliances are available in both 3 and 4 blade variants. In my personal experience I have only seen the 3 blade version to be widely used in India. The reason is again a mystery to me.

The accompanying device for a Fan is the speed regulator. This device regulates the speed of the fan having some pre-defined settings.

The speed settings are ranging from 0(off) to 5(high speed). Settings 1,2,3 and 4 offer increasing levels of RPM (revolutions per minute).

Essentially regulators like the one shown above reduce/increase the voltage that goes to the fan.

 In the last few years, these ‘resistor” based bulky box regulators are being replaced by electronic, solid state regulators. These are nothing but light dimming switches.

I have heard that just using dimmer switches to control the speed of the fan is not a good idea and that one should use dedicated electronic fan regulators for this job. The former, I believe delivers too less a voltage for the fan to function properly and can result in damage to the motor of the fan.

The most failing item in a fan which is used excessively is the Capacitor. The first signs of its failure are reduced speed of operation or completely dead fan.

A ball bearing is also used in fan to reduce the friction. Wear and tear in this can produce unwanted noise. So make sure you check these out.

Cleaning fans is probably one the most difficult task at home because it is hard to reach!

We try to cover more details on this in the coming days.

enjoy your Sunday !!
