Electricity usage of a Central Air Conditioner A central air conditioner is used in a home to provide cooling by circulating cool air through ducts from an air conditioner unit typically situated outside the house. 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. An average central ac will use 3000 to 5000 watts of power every hour for around 9 hours a day during the hotter months. Click calculate to find the energy consumption of a central air conditioner using 3500 Watts for 3 hours a day @ $0.10 per kWh. Running 3 hours a day is the same as running 9 hours a day for 4 of the warmer months. Hours Used Per Day: Hours Used Per Day: Enter how many hours the device is being used on average per day, if the power consumption is lower than 1 hour per day enter as a decimal. (For example: 30 minutes per day is 0.5) Power Use (Watts): Enter the average power consumption of the device in watts.

Price (kWh): Enter the cost you are paying on average per kilowatt hour, our caculators use the default value of 0.10 or 10 cents. To find an exact price check your electricity bill or take a look at Global Electricity Prices. To save energy with air conditioning the only real method is to increase temperature of your home, in hotter climates this may not be ideal. Staying cool by taking cold showers or using small portable fans can help. 3 ton heating ac unitIf you live in a hot climate your cooling costs can be significant, around 70% of your electricity bill. why does window ac unit leak waterInvesting in an energy efficient central conditioner unit fit precisely for the size of your home would be ideal. how to charge outdoor ac unit

To improve performance of your ac make sure to clear any debris, leaves or obstructions around your ac unit, so that you get better and more efficient air flow. Watts Volts Amps Ohms Gift Template - Free Gift Certificates I have an AC unit with the following specs: Cooling Capacity: 1260 kcal/h, 1.47kW, 5000 Btu/h Fan Motor Power: 0.034 kW My question is how much power does this unit actually consume in an hour? Does it use 1.47kW constantly? Btw it's a York unit. Is that a good brand? It will only draw that level of power when the compressor is running. In normal circumstances it will cycle on and off to chill the cooling element as needed; the rest of the time only the fan will be running to blow air over them. The amount of power consumed will vary depending primarily on how hot it is and what temperature you have the AC set to. To find out how much power it's actually using, you'll need to use a power meter of some sort. I'm partial to the Kill-a-Watt if they're available where you live.

You do not have enough information to calculate the electrical power consumed during operation. The three quantities listed, 1260 kcal/hr, 1.47 kW and 5000 BTU/hr, all represent the same power level, simply given in different units. They all give, as stated, the cooling capacity: the rate of heat energy removal from the cooled space. A particular air-conditioner has a dimensionless number called the Coefficient of Performance. It is defined as the ratio of Energy Removed to Energy Consumed. This value, usually around 4 to 8, divided into your cooling capacity (preferably in kW), will give the electrical power consumption of the unit when running... Another possibility: Turn off most of the appliances in your house, especially anything that cycles, like your refrigerator. Go to your electric meter and figure out how much power your house is using. The procedure for this varies between meters, but if you call your power company, they might be able to tell you how to do it.

Turn on your A/C, let it run for a few minutes, and again figure out how much power your house is using. Subtract one from the other to get the power consumption of your A/C. Add together the kW from Cooling Capacity and the Fan Motor. 1.47 + .034 = 1.504 kw or 1504 w. It appears that this is for a 220 v circuit ( 34w / .155A = 220v based on the fan rating). So your total draw would be 1504/220 = 6.84 A.Browse other questions tagged electrical hvac air-conditioning or ask your own question.For Residents » Save Energy It takes just a little energy to save on energy costs.
