4 years ago. The power consumption of air conditioners is determined by two factors: Runtime, or compressor speed. The 318-watt average mentioned (source: U.S. DOE) adds up to 228 kWh per month. It won’t draw this much current for more than a few seconds, and is therefore irrelevant to your electric bill. People often buy 5,000 BTU air conditioners for college dormitories and small apartments. Officially, BTU is a unit of energy, and watt is a unit of power, so they're not interchangeable. Let's Get It Fixed! A clogged condenser with inadequate airflow may overheat, reduce its ability to dispel heat outside (decreasing efficiency), and damage the compressor. 5,000 BTU air conditioners are recommended for rooms less than 200 square feet (ideally less than 150 square feet). EER is Energy-Efficiency Rating that you can usually find in specification sheets of 5,000-18,000 BTU AC units. Of all the electrical ratings printed on the label above, the only one relevant to your electric bill is the one marked ‘STD INPUT POWER’. That is, in comparison, higher amperage than it’s needed to power an 18,000 BTU portable air conditioner (about 13-19 amps). Example power consumption chart for sizing a generator. We can now conclude that the EER of this unit is 9.47 by dividing the BTU/h rating (18,000) by the standard power input rating (1900). How many amps does a 8000 BTU portable air conditioner use? Fortunately, room air conditioners come with an EER rating. Bear in mind that you should not purchase an oversized unit, as this may compromise the air conditioner’s performance and even promote mold growth due to excessive humidity. 0 0. An air conditioner on an average needs around 12-16 amps. You live on a plane. You can find the most efficient 24,000 BTU units (sorted by monthly energy usage) using our air conditioner finder. Use the dropdowns below to help you estimate what size air conditioner is best for your space. Air conditioner power consumption calculator is used to calculate the bill cost for any AC.

You can buy 9,000 BTU air conditioners, and find the most energy-efficient units ordered by energy usage with the help of our air conditioner finder. This includes both inverter and non-inverter units. =1200/220 = 5.5 amps. An inverter only runs at the level required, so if you oversize it will only ever run at part load. You could waste 16% more energy for every degree (Celsius) that you turn down your thermostat temperature below 25 °C, or 8% more for every degree Fahrenheit you turn it down below 78 °F. $0.20 is a common rate in Europe (many European countries are in the range of $0.19 to $0.25/kWh). Your electricity bill will be a little higher but you won’t need to sweat if you bought an AC unit that’s too small. So for inverter ac the current will be. Source(s): https://shrink.im/ba49m.

At the touch of a button, you can find out how many watts does a 8000 btu air conditioner use. The higher energy-efficiency device from Example 2 (12 EER) delivers 100% more cooling power than the 5,000 BTU device from Example 1 (10 EER). Below you find a table of how many watts do different air conditioners – from 5,000 BTU to 18,000 BTU – use. Here is how we calculate the amps required to power the unit: I (in Amps) = 5,000 BTU / (10 x 115V) = 4.35 Amps. Also Read: Heater Power Consumption, Ordered By Unit Size. A 12000 BTU air conditioner draws close to 15 amps. Therefore, a 24,000 BTU [PDF] unit with an EER of 10 draws 2,400 watts (24000 / 2400). This data was obtained from the labels of six 220 volt units of the following brands: Pioneer, Senville, General Electric, Friederich, Haier, and LG. They will not incur a significantly higher electricity cost than smaller units because they don’t need to run as long as the smaller ones (in this case, i’m assuming that you’ll purchase an inverter model). Divide the input BTU of your air conditioner by the SEER rating to get the amount of watts it requires, and write that down. In some cases, very large units have a slightly lower EER (this means that they use more energy) than the average unit. You can check out the best window AC units here. Project Guide. Reply. In the case of a non-inverter/single speed unit, the compressor speed remains the same at all times and the unit shuts off when the desired temperature is achieved. Inverter units, on the other hand, adjust the speed of their compressors in response to cooling demand using techniques and technologies such as PWM and variable frequency drives (learn about PWM from Kompulsa’s PWM guide). =5.5/0.8= 6.8 amps. As an Amazon Associate we earn from qualifying purchases. The exact value depends on the BTU and the mode in which it is operating. This type of cooling system is used to cool the entire home, versus a window air conditioner that is used to cool a specific area or room of your home. The electrical current (measured in Amperes or ‘amps‘ for short) needed to run an air conditioner is directly proportional to how much the AC unit will affect your electricity bill. The cooling power of different types of air conditioners is based on BTU’s. These air conditioners come out 10 amps or more and need to be connected to a … Any additional details will also be helpful. The power consumption of air conditioners averages 318 watts (hourly, for a 24,000 BTU unit) in most American households. Pics of : How Many Watts Does A Mini Split Air Conditioner Use. They typically draw 2,500 to 2,823 watts. There is a chance for it to increase depending on the number of the air conditioning units installed in your RV and their individual sizes. The amp draw may vary based on numerous factors. 9,000 BTU ÷ 9 = 1000 watts The average is only 318 watts because air conditioning units automatically cycle their compressors on/off as needed throughout the day.

Based on our years of experience, Aircon Experts simplified the technique of calculating the perfect air-conditioner size (Better known as BTU size) required for all rooms and offices. As is the case with the 24,000 BTU, the EER of these units is not the best, but larger units do tend to have lower EER ratings than the smaller ones. These units can be used in smaller rooms. RV air conditioners are typically either 15,000 Btu (British thermal units) or 13,500 Btu, although other sizes exist as well. After seeing the power consumption data above, you may be concerned about the high energy usage of air conditioners, but don’t worry — This can be reduced substantially with the following tips (which are intended specifically for residential air conditioners, although they may be helpful in other cases). The current rating of 24,000 BTU air conditioners is often in the range of 8.4 amps to 12.7 amps.

You can divide the BTU by EER rating (something like 5,000 BTU / 10 EER = 500W) . I only have a 20 Amp circuit breaker and it works well with the cooling of the air conditioner. If you don’t point the fan at yourself, it won’t be very helpful. The unit won’t draw as much as the locked rotor current unless it fails to start (due to a locked rotor, that is), and the ‘MAX. 9,000 BTU A/C units are recommended for rooms that are 350-400 square feet (this average applies to both window and split units). One Btu/h is equal to 0.29307107 watt. People with smaller units may not want to turn them off because they might take too long to cool back off when they return. For air conditioners, there is a BTU-to-room sizing rule of thumb. Below the table, you will find what factors determine the number of amps needed and how you can calculate how many amps your air conditioner uses. 9 years ago. These are easy to find. However when using the heater the demand for more electric power trips the circuit breaker and shuts off. Save my name, email, and website in this browser for the next time I comment.

For large rooms, I would recommend a standing fan which is at least 16″, but no more than 20″ to keep noise levels and power consumption down. Qualifies for federal tax credit - ENERGY STAR Certified. The power consumption of inverter air conditioners can be controlled in real time because increasing the thermostat temperature decreases compressor speed, thereby reducing power consumption immediately.
