How to Use Car Air Conditioning?
3 Answers
Car air conditioning is used as follows: 1. Cooling mode: After starting the car, turn the knob to the cooling direction and press the AC button and blower switch; 2. Heating mode: Turn the knob to the heating direction and turn on the fan switch to blow hot air. To turn off the car air conditioning, adjust the fan speed switch to the 0 position. Car air conditioning is designed to adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to an optimal state, providing passengers with a comfortable riding environment, reducing travel fatigue, creating good working conditions for the driver, and ensuring safe driving.
Using the car air conditioner is actually quite simple, but as someone who has driven for ten years, I’d like to share some practical tips: Start the engine and let it run for a few minutes first to protect it. Then press the AC button to activate the system. If it’s an automatic AC, just press the AUTO button—it will automatically adjust the fan speed and cooling intensity based on your set temperature. To change the temperature, turn the control knob, usually between 22 to 26 degrees for the most comfort. Don’t forget to adjust the fan speed button or knob, and avoid setting it too high to save fuel. On hot summer days, it’s recommended to use the external circulation for a few minutes to dissipate heat before switching to internal circulation for faster and more efficient cooling. Also, check the AC filter and system regularly—cleaning it every six months can prevent odors and malfunctions. On long trips, avoid setting the temperature too low to prevent catching a cold—safety first. These tricks have saved me a lot on fuel and time, making every long trip much more comfortable.
As someone who prioritizes in-car health, be cautious with air conditioning to avoid harming your body. After starting the car, don’t rush to turn on the AC—first, open the windows for a few seconds to ventilate and expel hot air before closing them and pressing the AC button. Set the temperature moderately, ideally around 24°C, to prevent dizziness or dehydration from excessive temperature differences. Avoid directing airflow straight at your face or body; use the airflow control buttons to adjust the angle for greater comfort. Switching between recirculation and fresh air modes is crucial: use recirculation initially for rapid cooling on hot days, then switch back to fresh air mode to prevent CO₂ buildup. In winter, avoid overly high heating temperatures that can cause dryness. I also emphasize regularly replacing air filters to reduce allergens and annual AC system checks to prevent mold growth that could affect breathing. Maintaining a comfortable environment while driving safely is key—these small habits keep me healthy without compromise.
