Note that EER is sometimes erroneous based on cooling power and electrical power consumption as. For example 12000 BTU/hr = 3516.85 W. How to calculate the energy consumption by Air Conditioner (AC) load? Another important energy-related metric that you should know about air conditioning is the SEER rating. That would be out of this world; and it actually is. The kWh figure for annual energy consumption that is shown on the label is designed to assist you to calculate how much it may cost to run the air conditioner on an annual basis. Thanks! We will most likely be using it almost everyday for more than 10 hours. Total Power Consumption : = 6.48 units 1 kJ = 0.947 BTU. This calculator can help you calculate electricity usage of your air conditioner and the usage cost. Sometimes even the whole day. Hello Darwin, we’re not familiar with EER = Wt/We definition of EER. Hello Celso, what is the wattage of that pump? So, 3516.85W/1000W= 3.52 Cooling Capacity 7000kJ/hr Air Compressor – 1/4 HP Air Compressor – 1 HP Computer w/17 in. EER = 6629 BTU/hr / 583 W = 11.37. This is the most basic specifications that you should look out for. (std. Calculating EER from this would yield us 9000 BTU / 250 W = 36 EER. The relationship between BTU and power (in watts) of an air conditioner is determined by energy-efficiency EER rating. (Here’s the generic list from EMP (NASA) specialist = Water Well Pumps RATED RUNNING 1,000-2,500, Surge/STARTING 5,600 – 7,500 watts & required voltage 120 or 240. How much electricity does an air conditioner use? The above chart is based on a regular size home and is only indicative. The result you’ve shown is quite low – most AC units have an EER rating of between 8 and 12. Air conditioner wattage is not the easiest information to come by. I’m not sure if it’s wiser to buy Carrier now or it won’t make a big difference when it comes to consumption if I get LG. Hello Deborah, you’re right, with Submersible pumps, you will have a significantly higher start-up wattage. For the yearly energy bills, we’ve taken into account that the AC unit is running 8 hours per day for 3 months with the price of 1 kWh being 13 cents: You have air conditioners with EER 8 or EER 10 or EER 12 or even EER 14. What Is A Good EER Rating For An Air Conditioner? How Much Does It Cost to Run An Air Conditioner? What Is A Good SEER Rating For An Air Conditioner? Most manufacturers will provide the EER rating themselves. SEER is calculated by dividing an air conditioner's cooling output in Btu by its energy consumption in watts; units with a SEER of 14 or higher receive the U.S. Department of Energy's Energy Star rating. SEER = (1 × EER100% + 42 × EER75% + 45 × EER50% + 12 × EER250%)/100, Total Heat (BTU/hr.) Wattage is just one of the factors that you need to know to determine how much energy your air conditioner uses. We also calculated the EER rating for each AC unit: In the chart above, we’ve looked at the EER rating of portable air conditioners. The EER is most valuable for portable AC units while the SEER is most valuable for split-system air conditioners. What Is A Good SEER Rating For An Air Conditioner? That’s exactly what the air conditioner EER chart will try to illustrate. Here are some of the generators you can use: All these generations will cover the basic wattage needed to power your air conditioner. Rated power of an air cooler varies from 150 watts to 300 watts which is quite less considering the cooling effect they offer. Hello Andy, 1,000W can power a 8,000 to 12,000 BTU device; depending on the EER rating. A 900-watt air conditioner that’s left on for 12 hours each day will use si… air), Latent Heat (BTU/hr) = 0.69 x CFM x Δgr. In hotter climates air conditioners with EER above 10 should be selected.
