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

The components of an automotive air conditioning control system include the compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, pipelines, condenser fan, vacuum solenoid valve, idle speed controller, and control system. The automotive air conditioning system is divided into high-pressure and low-pressure pipelines. The high-pressure side includes the compressor output side, high-pressure pipelines, condenser, receiver-drier, and liquid pipelines; the low-pressure side includes the evaporator, accumulator, return pipelines, and compressor input side. The function of the compressor is to increase the pressure of the refrigerant, promoting its liquefaction and heat release in the condenser, and serving as a power source to circulate the refrigerant within the system. The function of the condenser is to cool the high-temperature, high-pressure gaseous refrigerant into a high-temperature, high-pressure liquid refrigerant.
I often drive long distances and have found that the car's air conditioning system mainly consists of several core components: the compressor that compresses the refrigerant is key, acting like a pump to circulate the coolant; the condenser for heat dissipation is usually located behind the front grille; there's also the expansion valve that controls the flow of refrigerant; followed by the evaporator absorbing heat to cool the air; plus the blower and fan that push the cold air into the cabin. The control panel has buttons and knobs to set the temperature, airflow, etc. Additionally, sensors detect the cabin temperature and automatically adjust it to ensure driving comfort. Regularly cleaning the air filter is important—if left unchanged for too long, it can cause odors from the vents and affect cooling efficiency. In summer, opening the windows to release heat before turning on the AC can save fuel.
