How to adjust the temperature of central air conditioning

How to adjust the temperature of central air conditioning? Analysis and practical guide of hot topics across the Internet

Recently, as the high temperature continues in summer, the use of central air conditioners has become a hot topic across the Internet. The following is a compilation of hot air-conditioning-related content with the highest search volume on the entire Internet in the past 10 days (as of 2023):

1. Scientific basis for central air conditioning temperature regulation

According to data from the China Academy of Building Sciences, the most suitable air conditioning temperature range for the human body is as follows:

2. Five adjustment techniques that are hotly discussed on the Internet

1.step cooling method: The initial temperature is 3-5°C lower than the outdoor temperature, and is adjusted upward by 1°C every hour to the target temperature to avoid colds caused by excessive temperature differences.

2.The Golden Rule of Wind Direction: The horizontal air supply angle should be 20° higher than the human head to avoid direct blowing. Data shows that correctly adjusting the wind direction can improve comfort by 40%.

3.Smart mode application: Huawei’s whole-house smart user data shows that using the AI temperature control system can save 25%-30% energy.

4.Regional differentiated control: The recommended temperature is 26℃ for the living room and 28℃ for the bedroom. The air supply in the kitchen can be turned off. Actual measurement data from a certain brand show that zoning control can reduce energy consumption by 18%.

5.Fresh air system collaboration: When the CO₂ concentration exceeds 800ppm, the fresh air will be automatically started to maintain the freshness of the air.

3. Temperature setting solutions for different scenarios

4. Common Misunderstandings and Expert Suggestions

1.Low temperature ≠ rapid cooling: Experiments have proven that the cooling speed is only 3-5 minutes faster when set to 20°C than to 26°C, but the energy consumption increases by 50%.

2.Frequent switching consumes more power: The instantaneous power when the compressor is started is 7 times that of normal operation. It is more economical to keep running for a short time.

3.Temperature sensor maintenance: 75% of the decrease in air conditioning effect is due to dust accumulation on the sensor. It is recommended to clean the filter every month.

4.The importance of humidity regulation: When the humidity exceeds 70%, the body temperature will rise by 2-3℃, and the effect is better when combined with the dehumidification function.

5. Recommended settings for mainstream brands in 2023

Scientifically adjusting the temperature of central air conditioners can not only improve comfort, but also significantly reduce energy consumption. It is recommended that users make personalized settings based on actual scene needs and device characteristics, so that technology can truly serve the improvement of life quality.
