Why can't the air conditioner be turned on when it is cold in winter?

Because the outdoor temperature is too low, the air conditioner can't work normally, so it can't be started.

The air conditioner cannot be started in an environment below the limit temperature. Generally, the working limit of fixed frequency air conditioner is -7℃, and that of variable frequency air conditioner is-10℃. When it reaches -8℃ or-1 1℃, the air conditioner can still work, but the opportunity and time of defrosting will be greatly extended. The original defrosting time is 20 minutes and the warm air is 40 minutes. It's 40 minutes now.

In cold weather, it is not that the air conditioner is not heating, but defrosting the condenser. Due to the high humidity in winter, the condenser is easy to freeze and frost. The blades of some air conditioners are frozen. Users can remove the ice visible outside, but there is still ice inside. Once forced to start, it will even destroy the air conditioner.

Matters needing attention in using air conditioning for heating in winter:

1, the temperature difference between indoor and outdoor should not be too large, and it is best to keep the indoor air conditioning temperature setting 8℃ higher than outdoor in winter. If the temperature difference between indoor and outdoor is too large, people are prone to catch a cold in a hot and cold environment; For the elderly and hypertensive patients, the excessive temperature difference between indoor and outdoor will hinder the cerebral blood circulation of the elderly and hypertensive patients, and it is easy to induce stroke.

Close the doors and windows when turning on the air conditioner. If it takes a long time, it will lead to indoor hypoxia, and bacteria and viruses will accumulate in large quantities. So every time you turn on the air conditioner for more than 2 hours, you should stop and open the window for ventilation.
