26℃ air conditioning is the most suitable?

Myth content: 26℃ air conditioner is comfortable and saves electricity.

Truth interpretation: The most suitable temperature for air conditioning is not necessarily 26℃, but setting the temperature higher will save more electricity. Because the most suitable temperature of air conditioner is related to human feeling, indoor and outdoor environmental temperature, humidity, wall heat conduction, sunlight exposure, indoor dynamic changes and other factors, the temperature of air conditioner will be dynamically adjusted in large buildings to achieve the purpose of energy saving and emission reduction. Generally, it is enough to set it at 26-30℃ at home. The power consumption of air conditioners is related to local meteorological conditions such as temperature, humidity and wind speed, the energy efficiency level of air conditioners, the refrigerants used and the structure of air conditioners. Setting the temperature to rise by one degree may have different effects, but many experiments show that the general trend is "increasing the temperature by one degree to save electricity".
