How Much Energy Does An Ac Fan Use

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.

How much energy does an ac fan use.

Particularly large units can exceed the electricity usage of even central air. You probably won t run it at full capacity so it may not use the full wattage. If yours does bring in some outside air its probably not more then 20 or so. How much electricity does a portable air conditioner 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. Also if your goal is to get outside air inside the window fan is a much better bet. Energy usage of about 40 watts at medium speed is typical. 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.

The electricity consumption of a ceiling fan ranges widely depending on the design and the speed setting of the fan. A typical ac fan motor uses about 500 watts when it s running. As you can see a fan will use a minute fraction of this. Fans in general do not consume a lot of energy.

If you re running your central air conditioner on fan only mode however energy usage drops to about 750 watts per hour. 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. My window ac unit just recirculates indoor air.

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. Mid sized portable air conditioners use an average of 2900 watts per hour. Therefore if you run the fan continuously for a 30 day month 720 hours you would use 360 000 watt hours 720 x.

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

Ac fans are more prevalent so let s use that as our example. When set at low speed fans use between 15 and 30 watts and at high speed they consume between 50 and 100 watts. A central air conditioner can use 10 15 000 watts. If you don t have one a box fan is great in sucking the warm air out of a room on a hot day.
