Let’s learn how to calculate air conditioner electricity bills. As the heat gets stronger these days, more and more homes are turning on air conditioners. When I turn on the air conditioner, it feels really cool, but at the same time, I worry about the electricity bill. It’s cool right now, but I’m getting anxious because I’m worried about hitting a huge electric bill at the end of the month. However, according to the calculations, even if you play it all day, it will not be a burdensome amount. Now, let’s learn how to calculate air conditioner electricity bills.
Of course, power consumption varies depending on the type of air conditioner. The biggest difference is whether or not an inverter compressor is used. All air conditioners released recently are equipped with inverter compressors, so their power efficiency is much higher than that of existing air conditioners. Additionally, the electricity consumption rate varies depending on whether it is a wall-mounted air conditioner or a stand-type air conditioner. Stand air conditioners typically consume about three times as much electricity as wall-mounted air conditioners. However, the cooling power is excellent. Once the room is cooled, the air conditioner automatically adjusts its power, so there may not be a significant difference in overall energy consumption.
Summary: It depends on whether there is an inverter compressor or not and whether it is a wall-mounted or stand-up air conditioner.
According to experimental results, when using an inverter-type air conditioner, there is no significant difference in electricity usage between turning the air conditioner on all day and turning it on and off for 5 hours. When tested with a standing air conditioner, the power consumed when running all day is approximately 8 kWh. When calculating the rate assuming that the current maximum progressive tax range is 450 kWh (280 won/kWh), the electricity bill is approximately 2,300 won.
If the electricity bill is 2,300 won when you turn on the air conditioner all day, isn’t it as bad as you think? If you turn it on for a month in the summer, it costs about 70,000 won, which feels cheap compared to the gas cost for heating in the winter. Of course, the results of this experiment are based on an experiment with an air conditioner with an inverter compressor, so you need to be careful because if you leave it on all day with a basic compressor type air conditioner, your electricity bill could be really high.
Summary: Even if you leave the air conditioner on all day, your electricity bill will be around 2,300 won per day. (Only for air conditioners using inverter compressors)
If you plan to turn on the air conditioner, we recommend setting the temperature to 25 degrees or higher. If the set temperature is low, the air conditioner must continuously turn the compressor to maintain the temperature, greatly increasing power consumption. The greater the difference between outside and indoor temperatures, the greater the loss of cold air, so your electricity bill increases significantly for every degree lowered. Even if you set the temperature to around 25 degrees, you can feel much more comfortable compared to outside, and the reason for this is the dehumidifying function of the air conditioner. Even if the temperature is a little high, if the humidity is low, the discomfort index will definitely go down. In the summer, indoor humidity usually rises by more than 70%, but simply turning on the air conditioner can bring it down to 50%, which can have a big effect.
While researching this data, I also found out that it is much better to just leave the air conditioner on than to turn it on and off. There’s no need to turn off the air conditioner when you’re paying a similar price, right? I hope everyone has a cool summer.
