What is the difference between automatic and manual car air conditioning?

[JordanDella]

The difference between automatic and manual car air conditioning lies in their operation: automatic air conditioning does not require frequent adjustments. Once the temperature is set, it automatically maintains a stable temperature inside the vehicle and intelligently switches between internal and external circulation to ensure reasonable air quality inside the car. Manual air conditioning, on the other hand, requires manual adjustment of the fan speed. Car air conditioning consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components, designed to regulate the temperature and humidity inside the vehicle, providing a comfortable environment for passengers. When the compressor is operating, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator, compresses it, raising the refrigerant's temperature and pressure, and then sends it to the condenser.
