Fan Vs Ac Electricity Consumption

According to the article.

Fan vs ac electricity consumption.

Ac fans are more prevalent so let s use that as our example. New models feature high rpm s and cfm s to effectively aerate the room wihtout using too much energy. Box fan power consumption tends to be pretty low. Based on our calculations this means that it costs far less than 0 01 per hour to run making it extremely economical.

It may seem logical to think that a fan for an air conditioner is the same as a fan that you use in a room thought this is not the case. A typical ac fan motor uses about 500 watts when it s running. An ac unit on fan mode usually consumes about 150w with the fan running while the ac unit consumes 1000w when on default or cool mode. Take the hurricane classic box fan one of the options in this list of box fan reviews it uses just 55 watts.

Electric fans are made with energy efficient low watt motors designed to use as little electricity as possible. When set at low speed fans use between 15 and 30 watts and at high speed they consume between 50 and 100 watts. Ac vs fan electricity comparison data. I already had suspected that an air conditioner would draw more electricity to work that a standard ceiling or box fan but i wasn t ready for what i discovered.

Most ceiling fans average between 5 000 6 000 cfm s. The electricity consumption of a ceiling fan ranges widely depending on the design and the speed setting of the fan. The fan mode and switches are one such example. However the difference in power consumption will largely depend on a few factors such as how cool the unit is set to.

There are ceiling fans with high cubic feet per minute cfm available at affordable price points. The cost of air conditioning vs. A good ceiling fan it draws only 30 watts to run costing about 1 cent per three hours of use. A dc fan as opposed to an ac fan running directly on the 110 volt alternating current coming out of your wall outlet is extremely.

Let s also ignore efficiency and power factors because they re immaterial. How much electricity does a box fan use. With the depletion of the ozone layer everyone wants to conserve energy. As you can see below not only does an ac unit use more electricity but it requires a huge amount of power compared to a fan.

A three ton central air unit a common cooling system runs on about 3 kilowatts and costs about 36 cents an hour to run. The fan mode for central air conditioning systems is entirely different from the fan mode for window box air conditioning units. Energy usage of about 40 watts at medium speed is typical. Fans in general do not consume a lot of energy.
