Whether the air conditioner is turned on at 20 degrees or 26 degrees in winter is a matter of great concern, which is not only related to the comfort of indoor temperature, but also directly affects energy consumption and energy bills.
Scientifically speaking, the indoor temperature that the human body feels comfortable in is around 20, and the temperature that is too low or too high can make people feel uncomfortable. In winter, if the indoor temperature is lower than 16 for a long time, it is easy to cause problems such as cold hands and feet, joint pain, etc.; If the indoor temperature is higher than 22 for a long time, it is easy to make people feel dry mouth, **dryness and other discomforts. Therefore, the appropriate range for indoor temperature in winter should be between 16 and 22.
When it comes to air conditioner use, many people think that setting the air conditioner at around 20 in winter will save power, while setting the temperature at 26 will be warmer. In fact, this is not absolute, because the power consumption of an air conditioner is not only related to the temperature setting, but also related to factors such as the size of the room, the orientation of the room, the size of the window, the number of people in the room, etc. If the room is large, the number of people is small, or the orientation and window size of the room are appropriate, then setting the air conditioner at around 26 may be more comfortable and energy-efficient.
In addition, for families with elderly people and small children, the indoor temperature should be appropriately adjusted in winter to ensure that they do not feel cold. And for young people, the temperature can be lowered appropriately to save energy. However, it should be noted that the temperature should be adjusted moderately, not too low or too high, so as not to cause adverse effects on the body.
In short, whether the air conditioner is turned on at 20 degrees or 26 degrees in winter depends on the actual situation. On the premise of ensuring comfort, you should try to choose a lower temperature to save energy. At the same time, when using the air conditioner, pay attention to maintaining air circulation and regularly cleaning the air conditioner filter to ensure indoor air quality and health.
