When the car turns on the warm air, press the automatic button. The heating switch is a thermometer or buttons with blue and red on both sides. The red part is heating, and the blue part is air conditioning; After turning the knob, the red part is gradually increasing the temperature, and the blue area is decreasing the temperature.
The basic principle of automobile air conditioning heating is very simple. After the warm air is turned on, the liquid cooled down after high temperature in the engine will flow through the warm air groove, and the wind blown by the blower will also pass through the warm air groove, so that the air conditioner outlet can blow warm air. Warm air is not suitable for blowing directly on the head. Long-term blowing will cause driver fatigue and interfere with safe driving.
The enhancement of rapidly increasing the temperature inside the car is to start the engine to complete preheating, and then turn on the heating and air conditioning after the engine temperature pointer reaches the middle. In addition, set the air circulation to external circulation, let the cold air in the car be discharged outside the car, wait for 2 to 3 minutes, and then set the air circulation to internal circulation.
Matters needing attention in turning on warm air in automobile
Due to the low outdoor temperature in winter. Many car owners like to turn on the warm air as soon as they get on the bus. This method is incorrect. Because the temperature of the water tank was still relatively low when the engine was just started. At this time, turn on the warm air. Not only will it not increase the temperature inside the car, but it will increase the burden on the engine. Delayed the normal rise of engine water temperature.
Because the space inside the car is too closed and the temperature is too comfortable. Drivers may feel sleepy. At this time, it is necessary to open a small slit in the window for ventilation. Or start an external loop. Ensure the mobility of the air inside the car.
Because the outdoor temperature is too low, many people want to warm up as soon as they get into the car. Choosing to let the air outlet blow directly at yourself will make the skin that is already dry in winter drier. Drying is also easy to generate static electricity. It is best to let warm air blow to the roof or feet. You can also install a humidifier in the car to adjust the air quality inside the car. Don't wait for someone or have a rest in the car with the heating on and the windows closed.
Some people like to sleep in cars with warm air and closed windows. In fact, this is very dangerous. It is easy to cause carbon monoxide poisoning. It is best to turn off the heating or open the window for a long time. Never covet comfort and neglect safety.
