What is the correct way to use car air conditioning in summer?

The correct way to use car air conditioning in summer is: 1. Sit in the car and open the windows for ventilation; 2. Start the engine and turn on the blower to expel contaminated and hot air from the AC system; 3. After 5 minutes of natural ventilation, press the AC button; 4. Close the windows after 1 minute of cooling. Methods for using and maintaining car air conditioning: 1. Avoid setting the temperature too low; 2. Adjust the vent direction properly; 3. Don't use it continuously for extended periods; 4. Occasionally use higher fan speeds; 5. Turn off AC during low-speed driving. The main components of a car AC system are: compressor, condenser, evaporator, receiver-drier, and expansion valve.

In summer, the one thing I can't do without while driving is the air conditioning, especially during those scorching commutes! Don't turn on the AC immediately after getting in the car. First, roll down all the windows to ventilate for a minute and expel the hot air, then close the windows, start the engine, and hit the AC switch. Setting the temperature between 24 to 26°C is just right—don’t be greedy and crank it below 20°C to avoid catching a cold from the drastic temperature change when exiting the car. Adjust the fan speed to medium, start with the external circulation to exchange air, then switch to internal circulation to cool down faster. For automatic models, just press the AUTO button—it intelligently adjusts temperature and fan speed. I also make it a habit to clean the AC filter every month; a clogged filter can accumulate dust and blow out unpleasant odors! Long drives with the AC on might make you drowsy, so remember to play some music or take a 5-minute break to turn off the AC and get some fresh air—balancing safety and energy efficiency.

When it comes to summer car usage, I believe the air conditioning should be used wisely for both fuel efficiency and comfort. First, open the windows to dissipate heat, especially after the car has been exposed to the sun. Let the hot air escape for three to four minutes before closing the windows and turning on the AC. Manually setting the temperature to 25-26°C is sufficient—too high won't cool you down, and too low wastes fuel. Start with the external circulation mode to purify the air inside the car, then switch to internal circulation after about ten minutes for better energy efficiency. Cars with automatic AC are super convenient—just press the AUTO button and forget about it. Avoid directing cold air straight at your face or children to prevent catching a cold. Remember to check the filter every season; a dirty one can reduce cooling efficiency. Keeping the AC at a comfortable temperature while driving helps reduce fatigue, and I always carry a bottle of water to stay hydrated.

I prioritize environmental protection while driving. In summer, I avoid turning on the air conditioner immediately and instead roll down the windows to let the heat escape for two minutes. After starting the engine, I set the temperature to the balanced point of 24-26°C, avoiding excessively low settings to reduce emissions and fuel consumption. I keep the fan speed at medium or use automatic adjustment, and maintain fresh air circulation with the external air circulation mode. Regular cleaning of the air filter improves efficiency; otherwise, cooling becomes slower and adds extra burden. For automatic models, using the AUTO function is convenient and hassle-free. Keeping the cabin temperature within a comfortable range helps avoid significant temperature differences that could reduce focus, ensuring safer and more energy-efficient driving.
