Fan Vs Ac Electricity Consumption

Box fan power consumption tends to be pretty low.

Fan vs ac electricity consumption.

Fans in general do not consume a lot of energy. Yes max in terms of power consumption ceiling fans are more efficient than air conditioners however they don t necessarily have to cost the same or more than an air conditioner.

Therefore if you run the fan continuously for a 30 day month 720 hours you would use 360 000 watt hours 720 x. Ac vs fan electricity comparison data. The cost of air conditioning vs. Let s also ignore efficiency and power factors because they re immaterial.

When set at low speed fans use between 15 and 30 watts and at high speed they consume between 50 and 100 watts. Most ceiling fans average between 5 000 6 000 cfm s. 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.

New models feature high rpm s and cfm s to effectively aerate the room wihtout using too much energy. 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. 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. According to the article.

Electric fans are made with energy efficient low watt motors designed to use as little electricity as possible. 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. The electricity consumption of a ceiling fan ranges widely depending on the design and the speed setting of the fan. A good ceiling fan it draws only 30 watts to run costing about 1 cent per three hours of use.

A three ton central air unit a common cooling system runs on about 3 kilowatts and costs about 36 cents an hour to run. With the depletion of the ozone layer everyone wants to conserve energy. Energy usage of about 40 watts at medium speed is typical. 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.

Take the hurricane classic box fan one of the options in this list of box fan reviews it uses just 55 watts. Ac fans are more prevalent so let s use that as our example. How much electricity does a box fan use. A good window ac unit runs on 1 2 kilowatts and costs 14 cents an hour to run.
