How Much Energy Does An Ac Fan Use

A more helpful comparison may be to an air conditioning unit.

How much energy does an ac fan use.

When set at low speed fans use between 15 and 30 watts and at high speed they consume between 50 and 100 watts. Even if you already have an air conditioner you can use a box fan along with it to help cool a room by circulating the air. A 10 000 watt ac running 12 hours a day at full capacity would cost up to 468 a month to run. As you can see a fan will use a minute fraction of this.

The fan mode and switches are one such example. You probably won t run it at full capacity so it may not use the full wattage. The fan mode for central air conditioning systems is entirely different from the fan mode for window box air conditioning units. Let s also ignore efficiency and power factors because they re immaterial.

An average central ac will use 3000 to 5000 watts of power for around 9 hours a day during the hotter months. The energy use of a central air conditioner highly depends on the climate of the region a central air conditioner will run 3 to 7 months of the year depending on the outside temperature.

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. Fans in general do not consume a lot of energy. Also if your goal is to get outside air inside the window fan is a much better bet. Moreover since it doesn t use that much energy it s great for the environment as well as for your pocket.

A typical ac fan motor uses about 500 watts when it s running. If you don t have one a box fan is great in sucking the warm air out of a room on a hot day. How much electricity does a portable air conditioner use. Particularly large units can exceed the electricity usage of even central air.

Therefore if you run the fan continuously for a 30 day month 720 hours you would use 360 000 watt hours 720 x. A central air conditioner can use 10 15 000 watts. If you re running your central air conditioner on fan only mode however energy usage drops to about 750 watts per hour. My window ac unit just recirculates indoor air.

If yours does bring in some outside air its probably not more then 20 or so. Mid sized portable air conditioners use an average of 2900 watts per hour. The electricity consumption of a ceiling fan ranges widely depending on the design and the speed setting of the fan. 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.
