How to turn on the warm air in winter?

Warm air works differently from cold air. Automobile air conditioning is to liquefy the refrigerant by pressurizing the compressor, then vaporize it, and achieve the refrigeration effect by absorbing a lot of heat in the air. The work of the compressor will increase the load of the engine, so the fuel consumption should be increased. The warm air mainly comes from the heat of the water tank, and the heat is introduced into the car through the blower. Even if the hot air port is closed, the heat will be dissipated to the outside of the car, so the warm air in the car belongs to waste utilization, thus basically not increasing fuel consumption.

To turn on the car heater:

Turn on the warm air when the car is hot, that is, when the hot air in the car circulates. External circulation for 5 minutes, and then switch to internal circulation.

After the air conditioner is turned on, there are several things that people in the car should pay attention to. First, don't sleep in the car with the heating on after the car stops, which is easy to cause carbon monoxide poisoning!

The other is not smoking. If you smoke, it will cause air pollution to all passengers on the bus, and it will also make the air conditioning filter suffer and lose its reputation!

Another small coup for heating is to adjust the wind direction and blow the glass directly when there is fog in the wind before winter, which can dispel the fog in three minutes!
