Which uses more electricity, air conditioning on all the time or on and off? Summer this way with air conditioning electricity costs double!

In summer, the air conditioner has become a “life-saving artifact”, many people will worry about the cost of electricity. However, often some seemingly power-saving operation, but let the air conditioning power consumption soared! For example: frequent switching on and off, the temperature is adjusted too low, the direction of the air outlet is not right ...... these wrong usage, you may be committing every day!

Air conditioning is always on vs. switching it on and off, which is more power consuming? Frequent switching instead of electricity

Temporarily go out to pick up a courier, throw a garbage, many people feel that the air conditioning will be turned off to save more power, in fact, can not, frequent switching instead may also be more power-consuming ......

Beijing Science Center WeChat public number 2022 publication pointed out that the principle of air conditioning work lies in the heat exchange brought about by the flow of internal workmass, the main energy-consuming component is the pressurized air machine. Frequent switching will increase the start-up energy consumption, resulting in an increase in the total energy consumption, the result is not only not save electricity but cost electricity.

Do not use the temperature is too low or adjusted to sleep temperature, the air conditioner will automatically raise the preset temperature, which will narrow the indoor and outdoor temperature difference and reduce energy consumption.

When you sleep at night, is it better to open the window or turn on the air conditioner? Experts suggest that it is better to turn on the air conditioner

On a hot summer's day, is it healthier to sleep with the windows open, or is it more comfortable to turn on the air conditioner all night? The answer may surprise you!

Zhang Min 2024, deputy director of the Department of Occupational and Environmental Health at the School of Medicine and Public Health, Peking Union Medical College, pointed out on CCTV's “Healthy China” program that in rooms with air conditioning, the temperature and humidity can be adjusted and controlled. But if you open the window, it is not controllable, especially if you live in a room on a high floor, if there is strong convection weather at night, it is dangerous to sleep with the window open. Therefore, it is recommended to sleep with the air conditioner on, and the optimal temperature is 22℃~26℃.

Liu Qingquan, president of Beijing Hospital of Traditional Chinese Medicine, also said in the program, from the ancient people began to seek “air conditioning”, especially those summer resorts in the temperature between 24 ℃ ~ 26 ℃. Therefore, do not put the air conditioning, this kind of technology to change the good life to avoid using, this is cognitive error.
