air conditioner power consumption chart | air conditioner electric bill calculator

Basically A air conditioner is used to keeps our home or office cool,room air conditioners come in
various sizes and consume from 400 to 2000 watts.
Power consumption of Air Conditioner depend on various factor like star rating of Ac,No. of hours that the Air Conditioner is used,temperature setting of AC unit,geographical location,and so on.

How many watts does an air conditioner use per hour?

  • 5 Star AC 0.8 units in one hour.
  • 3 Star AC 0.96 units in one hour.
  • 2 Star AC 1.02 units in one hour.
For example 5 Star AC runs 8 hours a day, it Burn 6.4 units a day, and 192 units Burn in the Month.

How do you calculate your power consumption of Air Conditioner?

Electricity unit is kWh,which is also called as Board of trade Unit, kWh is equals to one kilowatt load used for 1 hour.
Units = P(in Watts) * time(in seconds) / 3600000
Units = P(in Watts) * time(in hours) / 1000
Units = P(in kilowatts) * time)(in hours)

How many watts does an air conditioner use per hour?

room air conditioners come in various sizes and consume from 400 to 2000 watts.Please look your  air conditioning carefully,you can find air conditioner wattage rated on it.Look like this

When compressor of the air conditioner is working :
Using power consumption formula
Units = Power * Hours of usage / 1000
When circulating fan is working while the compressor is working:
Average power usage of 80 W.
Units consumed = 80 * Hours of usage when the compressor is not working(off)/ 1000

Let's take an example :
Air Conditioner on for 10 hours a day, at 20 degree Celsius.
In this period compressor works for 4 hours and rest for 6 hours fan works.
Power Consumption Part 1 : 1500 * 4 /1000 = 6 units
Power Consumption Part 2 : 80* 6/1000 = 0.48 units
How much electricity does a air conditioner use?
Total Power Consumption : = 6.48 units
Ac Electricity Bill for a single day : = 6.48 * 6(Assume cost of 1 unit of electricity 6) = 38.8
Ac Electricity Bill for a month : = 38.8 * 30 = 1166.4

AC keeps our home or office cool. AC absorb warm air,and ejects the cold air,so that the hot air of the place turn into a cool and reduces the Temperature of the place.
Air Conditioner gives you coolness without any noise,so you can relieve without Mind disturb.This gives you Fresh Oxygen.With Air conditioner, you comfortable to Work.The Use of Air conditioner increases obesity, in a cold place  our body does not release the Energy, so that increasing body fat.You can also get tire by staying longer in the Air conditioner.It may also make you feel a headache and irritated.Air Conditioner also damage skin, which reduces the moisture of the skin.

It gives you a feeling of coolness, even without a voice, so it has become more of an AC everywhere.
Air Conditioner Machine mainly consists of 3 parts
Compressor and condenser are installed outside the Room of the Air conditioner,and evaporator are installed inside the Air conditioner Room.The main task of air conditioner is to cool the air inside the Room, when you turn AC On.when you set a Temperature,then thermostat of the AC calculate the difference between Temperature you have set and temperature of the environment,and  automatically maintain temperature.
The hot air passes through the Grill pipes refrigerant in the AC,which absorb its heat,and the evaporator coils turn the moisture out.

If you are planing to buy Air conditioner then Take care of these things:
  • Energy saving:Before taking AC, everyone is worried about the electricity bills.For this, star rating is given in AC. The higher the star rating in the AC,lesser the power consumption ,this will reduce your bull.For saving power and electricity  bills, you can buy AC with a rating of 4 or 5 stars.
  • Split AC does not have the noise problem.because its compressor is quite far from your AC room. But in Window AC you should take care of the sound. Otherwise, Air Conditioner may cause problem in your that select a AC which make less noise.
  • The quality of the air given by AC is very that taking the AC with the latest filter is a better deal.The filters present in the AC not only give clean air but also increase the cooling capacity of the room and also reduce the power consumption.However, AC filters require daily cleaning.
  • This is one of the most important must buy a AC according to the size of the room,so that it cools the room well. The best way to measure this is to check how many square meters your room is and multiply it by 80. After this you can easily estimate that how much watt is required for AC to cool every square meter. If there is a direct sunlight on the walls of the room then you will need a high capacity AC.
