What happened when the air conditioner suddenly stopped working in snowy days?

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, indoor and outdoor temperature difference should not be too big. In winter, it is best to keep the indoor temperature 8℃ higher than the outdoor temperature. If the temperature difference between indoor and outdoor is too large, people are easy to catch cold in the hot and cold environment; For the elderly and hypertensive patients, the 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.

2, air conditioning closed doors and windows, a long time will lead to indoor hypoxia, bacteria, viruses will also take the opportunity to accumulate a lot, therefore, every time more than 2 hours, you should stop the air conditioning, and open the window for ventilation.
