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

[LaLawson]

Car air conditioning consists of a refrigeration system, heating system, ventilation and air purification devices, and a control system. Here are some precautions for using car air conditioning: 1. Do not turn on the heating air conditioning immediately when warming up the car in the morning. Wait until the engine coolant temperature rises before turning on the air conditioning. 2. Do not set the air conditioning temperature too high. Prolonged exposure to excessively hot temperatures can cause drowsiness and affect driving. 3. If the airflow is weak, check if the air conditioning filter is clogged with too much dust. 4. During long-distance driving, ventilate the car periodically. Poor air circulation in a confined space can lead to breathing difficulties for passengers over time. 5. Turn off the air conditioning before parking and switch to the external circulation mode with natural air. This helps clean the air conditioning system's ducts and prevents bacterial growth.
