How Much Energy Does An Air Conditioner Use Compared To A Fan

A central air conditioner can use 10 15 000 watts.

How much energy does an air conditioner use compared to a fan.

You probably won t run it at full capacity so it may not use the full wattage. The cost of air conditioning vs. Sometimes running both a fan and an air conditioner gives you the benefit of air conditioning at a lower cost. While the amount may vary from model to model this rule holds true for all of them.

As you can see a fan will use a minute fraction of this. It is also important to consider the efficiency of running ac on fan mode compared to running an ordinary fan. How much does it cost to run an air conditioner for cooling. The fan mode for central air conditioning systems is entirely different from the fan mode for window box air conditioning units.

The fan mode and switches are one such example. Therefore if you run the fan continuously for a 30 day month 720 hours you would use 360 000 watt hours 720 x 500 or 360 kilowatt hours kwh. A three ton central air unit a common cooling system runs on about 3 kilowatts and costs about 36 cents an hour to run. A 10 000 watt ac running 12 hours a day at full capacity would cost up to 468 a month to run.

A central air conditioning unit consumes much more electricity than even several ceiling fans combined. Typical central ac energy consumption ranges between 2 000 and 5 000 watts per hour. A good window ac unit runs on 1 2 kilowatts and costs 14 cents an hour to run. 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. In large areas 50sqm it will cost between 0 70 and 0 95 per hour. The average reverse cycle air conditioner costs around 0 25 0 35 per hour to run for cooling purposes depending on the size of the room. A medium sized room of 36sqm would cost 0 36 0 70 per hour to run.

Even on the low setting an air conditioner uses as a very large amount of electricity when cooling. A good ceiling fan it draws only 30 watts to run costing about 1 cent per three hours of use. Using an ordinary stand fan is considerably more energy efficient compared to running ac on fan mode so consider using an ordinary fan and turning the ac off on days when the weather is relatively cool and you just want added ventilation. In terms of power consumption and energy saving it is clear that high volume fan is better compared to an air conditioner but a high volume ceiling fan is so expensive as a window type air conditioner thus saving on energy consumption is spent in buying the fan although a fan does not have a compressor unit or the number of components.

Therefore the fan uses about 360 kwh per month in the on mode. A smaller window unit consumes less electricity about 1 200 watts for a unit that requires 12 000 british thermal units but it won t cool your entire. A more helpful comparison may be to an air conditioning unit.
