The heating function of automobile air conditioner is provided by the warm air box of the vehicle. If the air conditioner wants to blow out hot air, the premise is that the engine temperature must be in a hot state, otherwise the air conditioner will only blow out cold air. There are many car owners who habitually turn on the warm air as soon as they get on the bus. In fact, this is not correct. Because the engine just started in winter, the temperature of the water tank is very low. After turning on the air conditioner, the temperature in the car will not rise rapidly, but it will also slow down the speed of water temperature rise, increase the burden on the engine and prolong the starting wear time of the engine.
The correct way is not to turn on the warm air after the engine is started, and then turn on the warm air when the vehicle has traveled a certain distance and the water thermometer reaches half of the normal water temperature. Just turn on the warm air, please choose a low air volume first, and then turn on the appropriate air volume according to your personal habits after the water temperature reaches normal.
