Especially if they yield such a high EER rating. That’s why the charges on your electrical bill are expressed in kilowatt hours. We will most likely be using it almost everyday for more than 10 hours. For example, a 1000W AC unit spends 1 kilowatt-hour of electricity per hour. Can you compare LG dual inverter vs Carrier X power gold 3 (Both 1.5hp). Brand is Carrier. That alone is a bit weird; obviously they mean 9000 BTU/hr. Which AC Units Have The Highest EER Rating? Hello Deidre, you would need a generator that can produce up to 1,500W. 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. I just purchased a 8000 watt gas generator as nothing I had could carry the huge load. However, other factors that determine which air conditioners are the best, is their track-record, the reliability of the brand, dehumidification rate, average airflow, and so on. What is a good EER for a portable air conditioner? Hi! The important part is this: the specification sheet list cooling power at 250 kW (obviously, that not kilo-Watts, it’s just Watts). Login. That’s very energy-efficient. Not knowing how many watts does a 5,000 BTU air conditioner use is actually pretty normal. However, if you want to compare the energy efficiency of a certain LG AC unit vs. a certain Panasonic AC unit, you can just check the EER rating. The EER is most valuable for portable AC units while the SEER is most valuable for split-system air conditioners. In short, if you want to save several $100s per year on electricity, you should look for highly energy-efficient air conditioners with high EER ratings. Sometimes even the whole day. 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. What Is A Good EER Rating For An Air Conditioner? The ones with EER below 8 are electricity guzzlers. Capacity . How Much Does It Cost to Run An Air Conditioner (Per Hour, Month)? Calculating EER from this would yield us 9000 BTU / 250 W = 36 EER. Energy Consumption Calculator; Energy Consumption Calculato. Hello Ace, if you can share specs (EER primarily), the price of both devices, and the price of electricity in your area, we can do some calculation to decide which one makes more financial sense. It does mean that it is more energy efficient right? Given that an average price of 1 kWh in the US is $0.1319, you can save quite a bit if you invest in an above-average energy-efficient air conditioner. 1. Do you 100% need the EER 14 or would EER 10 suffice? Air conditioners are likely one of the biggest consumers of power at your home or office. First, we need to convert 7000 kJ/hr in BTU/hr. Example: If a 10,000 BTU air conditioner is powered by 1,000 W, the EER rating is calculated as, EER = 10,000 BTU / 1,000 W = 10 EER rating. Hello Mogman, you’re exactly right, thank you for the heads-up; we’ve fixed the numbers according to your suggestion. EER rating calculation is fairly simple; EER = Capacity (in BTU) / Electrical Power (in W). 1 kJ = 0.947 BTU. A good EER rating, for example, is 10. Power Input 583W My Account View accounts & bills, make payments View the My Account page; MENU Mobile Navigation Menu. Window type Non Inverter. What Is A Good EER Rating For An Air Conditioner? In the table above we’ll assume that the EER rating of all AC units is between 8 and 12. Looking at the CS-VU9UKQ model specification sheet; the cooling capacity listed is 9000 Kj/h. Here are some of the generators you can use: All these generations will cover the basic wattage needed to power your air conditioner. While a 3000 W generator could run the pump, it can’t be used to start it up. That’s why you’ll see a range for the wattage of air conditioners with the same BTU number: As you can see from the table above, a 12,000 BTU air conditioner can use 1500W (8 EER rating) or 1000W (12 EER rating). You can see it at 1st place in the list of the best portable air conditioners. To determine the amount of watts that your cooling systems uses, you need to multiply the product’s wattage by the length of time that it is actually operating. Hello Jane, the higher EER rating equals to better energy efficiency, you are right. Thanks for the review. Click calculate to find the energy consumption of a room air conditioner using 1000 Watts for 3 hours a day @ $0.10 per kWh. The above chart is based on a regular size home and is only indicative. What btu rating if any can be run by a 1000watt LP generator? The unit they are using (Kj/h) is not equivalent to BTU/hr. For an example, let’s look at a 5000-BTU-per-hour air conditioner, with a SEER of 10 BTU/Watt-hours, operating for a total of 1170 hours during an annual cooling season (9 hours per day for 130 days). Then you have come to the right place where all that information in presented in the one place. I installed a new 8000 BTU window mount air conditioner on the weekend on a wall that is west facing. That’s how you can easily estimate that 5,000 BTU AC units use 500W of energy. You can estimate how many watts does an air conditioner with known capacity (BTU) use pretty well with this AC wattage calculator: Estimated Wattage (Based on 10 EER Rating). Hathaspace Smart True HEPA Air Purifier Reviews, list of the best portable air conditioners, EER Chart With Respective AC Electricity Costs. I plugged it into a Kill-A-Watt to monitor its power consumption and noticed in the morning, when the house and the outdoor temperature is at its coolest, it consumes 620-640 W. In the afternoon when the sun is on the unit, it consumes ~750W.
