What air conditioner is turned on in the car in cold weather?

In cold weather, the warm air will be turned on in the car.

There are generally two methods. Warm up first, start the engine before getting on the bus, let the engine reach enough heat before turning on the air conditioner. The second is to save travel time, turn on the air conditioner for a few minutes, and let your car "concentrate" on driving, instead of taking out more "energy" to help you operate the air conditioner.

Matters needing attention in the use of automobile air conditioner:

1, don't turn on the heating and air conditioning immediately when the car is hot in the morning, and then turn on the air conditioning when the water temperature in the engine water tank rises.

Don't set the temperature of the air conditioner too high. Excessive temperature for a long time will make you sleepy and affect your driving. In addition, don't let warm air blow directly on your face.

3. If the window begins to fog after the warm air is turned on, most people turn off the warm air or use cold air to drive the fog, which will cause repeated fogging, so increase the speed of the warm air and blow for a while, so the fog will disappear and will not appear again.
