What does AC on the air conditioner mean?
2 Answers
AC on the air conditioner refers to the air conditioning switch button. The function of the air conditioner is to regulate the temperature according to the set value, adjusting and controlling the temperature, humidity, air cleanliness, and air flow inside the car cabin to an optimal state, providing a comfortable environment for passengers and reducing travel fatigue. Tips for car air conditioning maintenance: 1. Avoid frequently turning the car air conditioner on and off; 2. Regularly check the compressor's lubricant level and refrigerant amount, with inspections and top-ups every two to three weeks; 3. Maintain the lubrication of the compressor and seals by running the air conditioner at least once a week.
Last time my friend asked me what the AC button on the car's air conditioning does, I explained it based on my actual driving experience: During the hot summer months, pressing the AC button is necessary to get cold air, as it activates the compressor to turn the refrigerant into cool air that blows out. If you don't press this button, you'll only get warm air from the engine or natural airflow, which is more useful for heating in winter. I remember one time during heavy rain when the windows fogged up, turning on the AC along with the defog mode quickly solved the problem because the cold air is excellent at dehumidifying. For highway driving, it's recommended to keep the AC on and windows closed for better fuel efficiency, as it reduces wind resistance significantly compared to driving with windows open. By the way, if you notice the cooling becoming weaker, it might be due to a refrigerant leak, and you should get it checked at a car repair shop.
