How much is the heating degree of air conditioning suitable in winter? What are the taboos of air conditioning in winter
4hw.com.cn: it's extremely cold in winter. Many families without heating begin to turn on the air conditioner. However, many people have different answers about how much the air conditioner is turned on. In fact, too high or too low indoor temperature is bad for the body. If the temperature difference is too large, it's easy to catch a cold. So how much is the air conditioner turned on in winter? Let's have a look!
1. The use of air conditioning should first make people feel comfortable. In terms of temperature, the temperature that makes people feel neither hot nor cold is called physiological zero. Physiological zero is the most comfortable temperature for people. Different people have different physiological zero degrees. For normal people who are generally healthy, the physiological zero is about 28 ℃ ~ 29 ℃. Therefore, the temperature of the air-conditioned room should be selected near this temperature as far as possible. Generally, the best temperature of air conditioning in winter is 20 ℃, but because the outdoor temperature in each region is different, you can adjust the temperature of air conditioning according to your own comfort, but it should not be too high. Too high is the most harmful to health, and it will overload the air conditioning, not only consume electricity, but also shorten the service life of air conditioning.
2. The use of air conditioning should be conducive to health. The temperature difference between indoor and outdoor shall not be too large, generally 5 ℃ ~ 10 ℃. If the temperature difference is too large, people are prone to colds and other diseases due to sudden changes in air temperature when entering and leaving. If the indoor and outdoor temperature difference is too large, people are prone to colds and colds in the sudden cold and hot environment. For the elderly and people with hypertension, the indoor and outdoor temperature difference should not be too large. Because the indoor temperature is too high, the human blood vessels dilate. At this time, if you suddenly go outdoors, the blood vessels contract suddenly, which will hinder the cerebral blood circulation of the elderly and patients with hypertension, and it is very easy to induce stroke.
3. Consider saving electricity when using air conditioning. When the temperature is adjusted too low during refrigeration or too high during heating, it consumes more energy. Therefore, considering power saving, the room temperature cannot be adjusted too low in summer and too high in winter.
4. Pay attention to health when using air conditioning. When opening the air conditioner, close the doors and windows tightly. A long time will lead to indoor hypoxia and a large accumulation of bacteria and viruses. Therefore, when the air conditioner is opened for more than 2 hours, it should stop and open the window for ventilation.
Therefore, the reasonable temperature of air-conditioned room should be 28 ℃ ~ 29 ℃ in summer. In winter, it should be 18 ℃ ~ 20 ℃. For rooms with few people, the temperature can be appropriately increased to 24 ℃.
