How Much Energy Does An Air Conditioner Use 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.

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

Energy costs of fans fans in general do not consume a lot of energy. 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. As you can see a fan will use a minute fraction of this. Typical central ac energy consumption ranges between 2 000 and 5 000 watts per hour.

It is also important to consider the efficiency of running ac on fan mode compared to running an ordinary fan. Even on the low setting an air conditioner uses as a very large amount of electricity when cooling. A medium sized room of 36sqm would cost 0 36 0 70 per hour to run. The fan mode and switches are one such example.

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. The fan mode for central air conditioning systems is entirely different from the fan mode for window box air conditioning units. A central air conditioning unit consumes much more electricity than even several ceiling fans combined. A typical ac fan motor uses about 500 watts when it s running.

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. While the amount may vary from model to model this rule holds true for all of them. How much does it cost to run an air conditioner for cooling. A good ceiling fan it draws only 30 watts to run costing about 1 cent per three hours of use.

In large areas 50sqm it will cost between 0 70 and 0 95 per hour. An air conditioner uses roughly about 5 9 times as much electricity as a 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. You probably won t run it at full capacity so it may not use the full wattage.

The cost of air conditioning vs. 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. A central air conditioner can use 10 15 000 watts. Sometimes running both a fan and an air conditioner gives you the benefit of air conditioning at a lower cost.

A more helpful comparison may be to an air conditioning unit. Therefore the fan uses about 360 kwh per month in the on mode. A good window ac unit runs on 1 2 kilowatts and costs 14 cents an hour to run.
