The temperature difference between indoor and outdoor should not be greater than 5℃. If the air conditioning temperature is not scientific in summer, the temperature difference between indoor and outdoor is too large, which will lead to air conditioning disease.
It is suggested to turn on less air conditioning and use more natural wind to reduce indoor temperature. On 3rd, the Legislative Affairs Office of the State Council published the draft Regulations on Energy Efficiency of Civil Buildings for comments, which stipulated that the state should implement an indoor temperature control system for public buildings that use air conditioning for heating and cooling.
Except for special purposes, the indoor air conditioning temperature setting shall not be lower than 26 degrees Celsius in summer and higher than 20 degrees Celsius in winter.
In summer, locking the air conditioning temperature at 26℃ is just right for skin care. When the ambient temperature drops by 1℃, the sebum secretion of the skin decreases by10%, and the skin with less sebum has poor water retention ability. Coupled with the air conditioner constantly pumping away the moisture in the air, the moisture of skin cells will continue to evaporate, and the moisture and oil of the skin will be missing at the same time, so it is strange that it is not dry! Therefore, don't blindly pursue low temperature when turning on the air conditioner in summer. If you want to be cool and not lose too much water, 26℃ is fine. If you are not too afraid of heat, you can even set it to 28℃.
Skin feels comfortable and dry. The air humidity is 50% ~ 60%. If the humidity is high, it will be sticky and uncomfortable. If the humidity is low, it will not only dry the skin, but also dry the throat. In an air-conditioned room, the air humidity decreases by 20% for every 5℃ decrease in ambient temperature, so the air-conditioning temperature is really not suitable for being too low in summer, and it is very comfortable to keep the humidity at 50% and 26℃.
Saving 1 kwh, what is saved?
Saving one degree of electricity can be: saving 0. 4 kg standard coal, reducing emissions by 0. 997 kilograms of carbon dioxide, reducing emissions by 0. 03 kg of sulfur dioxide, reducing emissions by 0. 0 15 kg of nitrogen oxides, reducing emissions by 0. 272 kilograms of carbon dust. If nearly 400 million households in China save electricity 1 kwh every month, it will save 4.5 billion kwh of electricity and reduce carbon dioxide emissions by 4,486,500,000 kg every year.
legal ground
Energy Conservation Law of the People's Republic of China Article 24 Energy-using units shall, in accordance with the principle of rational use of energy, strengthen energy-saving management, formulate and implement energy-saving plans and technical measures to reduce energy consumption.
Thirty-seventh public buildings that use air conditioning for heating and refrigeration shall implement indoor temperature control system. The specific measures shall be formulated by the competent construction department of the State Council.
