How to Use the Car Air Conditioning?

[Rochelle]

To use the car air conditioning: 1. After starting the vehicle, turn the air conditioning knob to the cooling or heating zone; 2. Press the AC button when cooling is needed. The functions of the car air conditioning are: 1. To provide a comfortable riding environment for passengers and reduce travel fatigue; 2. To create favorable working conditions for the driver, ensuring safe driving. Car air conditioning, also known as the car air regulation device, is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to an optimal state. Its components include the refrigeration system, heating system, air purification device, and control system.

After starting the vehicle, first press the AC button to activate the system, then adjust the fan speed knob to select the appropriate airflow. Turn the temperature control knob towards the blue zone for cooling and the red zone for heating. In summer, when using AC for cooling, it's best to pair it with recirculation mode for quick cooling, then switch to fresh air mode after the cabin cools down to ensure air circulation. In winter, you can directly adjust the temperature for heating without pressing the AC button. If the windshield fogs up, immediately press the front defogger button, preferably with fresh air mode to disperse the fog. Regularly check if the cabin air filter is clogged, as it can cause odors. Remember not to set the temperature too different from the outside to avoid catching a cold. On long trips, switch between recirculation and fresh air modes every two hours to maintain cabin comfort.

Using car air conditioning efficiently requires some know-how. In summer heat, don't rush to close windows - first activate external circulation for one minute to ventilate before switching to internal circulation cooling, which can save 20% fuel. Setting temperature around 24°C is most reasonable, reducing compressor load and saving energy. On rainy foggy days, use the defog mode aimed at windshield for three minutes for clear visibility. In winter, wait until coolant temperature gauge reaches midpoint before turning on heater to avoid wasting fuel blowing cold air. Occasionally running maximum fan speed for three minutes cleans duct dust. Pro tip: Turn off AC and switch to ventilation five minutes before parking to prevent mold growth and reduce odors.

When using car air conditioning, pay special attention to health details. Don't set the temperature too low - a difference of more than 10 degrees from outside may cause headaches. Don't keep the internal circulation on for over 30 minutes, otherwise the air will become stale and you'll need to open windows for 10 minutes to ventilate. When starting the car, first open windows for ventilation before turning on the AC to avoid inhaling volatile substances. Adjust the vent direction upward or toward feet - blowing directly at your face may cause dry eyes. Clean the AC filter monthly to prevent mold and bacteria spread. During heating, occasionally switch to external circulation to reduce CO₂ concentration for clearer driving.
