What mode is automatic?

Automatic: Automatic air conditioning mode.

Press the car air conditioner to turn it on, and control the air outlet temperature according to the sensor in the car, hot air in winter and cold air in summer. It will keep a proper temperature in the car. If the temperature is too high or too low, the air conditioner will automatically change the temperature and wind speed of the air outlet and adjust the temperature inside the car.

The comfort device of air conditioning system is an important index of internal temperature comfort of automobile. The inside temperature depends on the outside temperature, air flow and solar radiation. When the temperature outside the car exceeds 20 degrees Celsius, the comfortable temperature inside the car can only be achieved by cooling with cold air. The traditional air conditioner is manually controlled, and there is a temperature adjustment knob on the air conditioner control panel.

Principle of automobile sensor:

The sensors of automatic air conditioning control system generally include interior temperature sensor, exterior temperature sensor, evaporator temperature sensor, solar energy sensor, water temperature sensor and so on. Among them, the water temperature sensor is located at the water outlet of the engine and feeds back the cooling water temperature to the ECU. When the water temperature is too high, ECU can disconnect the compressor clutch to protect the engine.

At the same time, it also makes ECU control the valve of cooling water to the heating core according to the water temperature. Each sensor feeds back the temperature information to ECU, and ECU controls the temperature of airflow through the ratio of cold and warm air in "mixed wind stall". For example, when the temperature is too low, the ECU instructs the cold air to flow through the heating core to raise the temperature, and when the temperature is too high, the cold air is added.
