How much energy do ceiling fans use? - cars ceiling fan

And when I connect to a car battery, for example, how long they could stay away?

Craigory said...: Fans do not use more electricity than incandescent bulbs. Powers typical ceiling fan sizes are:

36 "= 55 watts
48 "= 75 watts
52 "= 90 watts
56 "= 100 watts

Of course, a car did not battery voltage. But if you're a good investor (90% efficiency), a battery of 100 A-hr could hold a 48 "fan is for approximately 10 hours.

(HR-100A x 12V) x 90% / 75 W = 14.4 hours, but can not really rely on the battery to full capacity in this application. It would depend on when the investor no longer function as the battery discharges.; January 21, 2010 at 8:56 PM
abcd_xyz said...: Check the amount of watts (W) Your fan, it must be consumed in small print is written somewhere in the fan. The amount of energy (joules) consumed every second.

Then look at the specifications of the car and see if she says how much energy is contained in the set. To be able to calculate how long it will keep your fan running.

I do not think the battery lasts long, however. Consume any mechanical device (like a fan) a significant amount of energy and the batteries are designed for a limited amount of energy available (eg by a spark to ignite the engine of the car or keep the lights on a time).

Also check the Watts on drums. W Are they too small to be compared to its S fan, the fan run very slowly. It makes little sense, then!; January 22, 2010 at 2:47 AM
