What Functions Should a Car Air Conditioner Have?

[MartinRose]

Here are the functions of a car air conditioner: 1. Ventilation System: Its role 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. In cold winters, the fresh air should also be heated to maintain a suitable indoor temperature. 2. Heating System: Its role is to heat the air inside the car or fresh air entering from outside to achieve warming and dehumidification effects. 3. Cooling System: Its role is to lower the interior temperature when the external environment is hot, providing passengers with a cool and comfortable environment. 4. Air Purification System: Its role is to filter the incoming air, continuously removing polluted gases from the car interior to maintain clean air inside the car. 5. Control System: The control system mainly consists of electrical components, vacuum pipelines, and operating mechanisms. Its role is, on one hand, to control the temperature and pressure of the cooling and heating systems, and on the other hand, to manage the temperature, air volume, and airflow direction inside the car to enhance the various functions of the air conditioning system.
