Why does the car air conditioner cool but not drain water?

[DiGia]

The reason why the car air conditioner cools but does not drain water is due to a lack of Freon. The functions of the car air conditioner are: 1. To achieve the cooling effect by continuously cycling the refrigerant through phase changes; 2. To remove dust, odors, smoke, and toxic gases from the air inside the car, making the interior air fresher, and to humidify the air inside the car. The maintenance methods for car air conditioners are: 1. Do not set the temperature too low; 2. Control the direction of the air outlet; 3. Do not use it for extended periods; 4. Appropriately turn on high airflow; 5. Turn off the air conditioner when driving at low speeds. The precautions for using the air conditioner are: 1. Do not set the temperature too low; 2. Control the direction of the air outlet; 3. Avoid prolonged use; 4. Appropriately turn on high airflow; 5. Turn off the air conditioner when driving at low speeds.
