The weather is so hot that I want to turn on the air conditioner, but I am afraid that the electricity bill will be too high to make people feel cold. According to the report of the Japanese women’s weekly magazine “Women Herself”, Harumi Maruyama, a money-saving expert, revealed that 34.2% of the electricity bill in summer is spent on air conditioners, while Many people misunderstand the concept of power saving, resulting in a lot of unnecessary waste. In this regard, she put forward 7 misconceptions of air-conditioning and electricity saving, and hoped that readers can also save energy correctly.
Mistake 1: The air volume adjustment is “weak”
Both the indoor and outdoor units of the air conditioner contain a “full heat exchanger”, which can bring in the outdoor air and extract the indoor air to maintain the indoor temperature. If the air volume is adjusted to “weak”, the time for converting heat will be longer, and the electricity bill will also rise accordingly. , so it is recommended to change the air volume to “Auto” to cool the room temperature more effectively.
Mistake 2: Covering the outdoor unit
Although the purpose of covering the air conditioner outdoor unit is to avoid direct sunlight, if there are debris around the outdoor unit, the air inlet and outlet will be blocked, which will increase the load of the air conditioner and waste electricity.
Mistake 3: Shutting down too often
The air-conditioning compressor is also known as the “heart of the air-conditioning”, which consumes about 80% of the electricity of the air-conditioning. As long as it is turned on, the compressor will start to run strongly, and will reduce the speed to run when it reaches the appropriate temperature. Therefore, turning on and off the air conditioner repeatedly will increase the load on the compressor and consume more power. If you only need to go out for 30 minutes, it is recommended to keep the air conditioner turned on.
Mistake 4: The wind is pointing down
The downward direction of the air-conditioning air will cause only the floor to be cool, while the warm air still stays in the upper part, resulting in temperature imbalance. Therefore, the air outlet should be kept in a horizontal state.
Mistake 5: Immediately close the windows and turn on the air conditioner when you get home
When you get home, you should open the windows first to let the hot air out of the room before turning on the air conditioner. It is also recommended to increase the temperature setting by 1 degree and set the air volume to automatic to save electricity more effectively. In addition, every 1 degree increase in the air conditioner can save about 10% of electricity.
Mistake 6: Cleaning the filter only once a season
If the air-conditioning filter is blocked by dust, it will not be able to inhale more air, but will require more electricity to cool down the temperature. Therefore, it is recommended to clean it every two weeks, and households with pets need to clean it once a week. According to Daikin estimates, if the filter is not cleaned for one year, it may consume 36% more electricity bills.
Mistake 7: Turn on the “Dehumidification” function instead of “Air Conditioning”
The most power-saving mode of air-conditioning is air-conditioning dehumidification (weak cooling room dehumidification), air-conditioning, and dehumidification. If the air-conditioner at home does not have the function of “air-conditioning dehumidification”, you can set the air-conditioning to 28 degrees, which can save more energy than dehumidification mode. electricity.
