Air conditioning set temperature:
1. It is advisable to set the heating temperature of air conditioner at about 20 degrees in winter.
The best temperature to turn on the air conditioner in winter is 20℃. Moderate indoor temperature is not only beneficial to health, but also can avoid air conditioning overload. When heating, use the low windshield at first and the medium windshield after half an hour.
In addition, when raising the indoor temperature, please be careful not to set the temperature at the limit of 30℃ that the air conditioner can withstand in winter, otherwise it will cause the air conditioner to start or not stop frequently, increase the power consumption, and even damage the air conditioner compressor in serious cases.
2. In summer and autumn, the most comfortable temperature for human body is about 26℃. If it is about 3℃-4℃ lower, the human body will feel a little cold. In addition, due to the different indoor and outdoor environments, long-term exposure to relatively extreme temperatures, the body's adjustment ability is unbalanced, which will lead to the decline of immune function and various discomfort symptoms over time, which is called air conditioning disease in medicine.
Therefore, it is suggested that under normal circumstances, it is best to adjust the air conditioner to about 26℃, and the temperature difference between indoor and outdoor should not exceed 7℃, otherwise it will increase the burden on the thermoregulation center.
