What are the main components of an automotive air conditioning system?

[SilasDella]

Modern air conditioning systems consist of a refrigeration system, heating system, ventilation and air purification devices, and a control system. Ventilation system: Its function is to ensure cabin ventilation while the vehicle is in motion, continuously introducing fresh air into the cabin while expelling dust, carbon dioxide, and harmful gases from the engine. Heating system: Its purpose is to heat the air inside the cabin or fresh air entering from outside, achieving both warming and dehumidification. Refrigeration system: Its role is to lower the cabin temperature when the external environment temperature is high, providing passengers with a cool and comfortable environment. Air purification system: Its function is to filter incoming air, continuously removing contaminated gases from the cabin to maintain clean interior air. Control system: The control system primarily consists of electrical components, vacuum lines, and operating mechanisms.
