What are the main functions of a car air conditioning system?

[Lilian]

Introduction to the main functions of car air conditioning: 1. Ventilation system: Its function is to ensure indoor ventilation while the car is in motion, continuously introducing fresh air into the car interior to expel dust, carbon dioxide, and harmful gases from the engine. During cold winters, the fresh air should also be heated to maintain a suitable indoor temperature. 2. Heating system: Its function is to heat the air inside the car or fresh air entering from outside, achieving the purposes of warming and dehumidifying. 3. Cooling system: Its function is to lower the interior temperature when the external environment temperature is high, making passengers feel cool and comfortable. 4. Air purification system: Its function is to filter the incoming air, continuously removing polluted gases from the car interior to keep the air clean. 5. Control system: The control system mainly consists of electrical components, vacuum pipelines, and operating mechanisms. Its functions include controlling the temperature and pressure of the cooling and heating systems, as well as managing the temperature, air volume, and flow direction of the air inside the car to optimize the various functions of the air conditioning system.
