What does AQS in car air conditioning mean?

[DelElliott]

Car air conditioning's AQS refers to the Air Quality Sensor in the vehicle. This sensor can detect air turbidity, humidity, and the presence of toxic substances, thereby controlling the air conditioning's internal and external circulation. The AQS system is highly sensitive to vehicle exhaust. During traffic congestion in urban areas, the AQS system will automatically close the external circulation and switch to internal circulation. Cars equipped with the AQS system usually come with automatic air conditioning, which is more intelligent than standard car air conditioning. When driving at high speeds, it's not suitable to open windows for ventilation, so the external circulation function of the air conditioning can be activated. In urban driving, when encountering traffic jams or areas with high dust levels, the internal circulation of the air conditioning should be used. The car's air conditioning system should be cleaned at least once a year. Otherwise, bacteria can proliferate inside the system, and the air blown out when the air conditioning is turned on may have an unpleasant odor. The air conditioning filter should also be replaced regularly to prevent bacterial growth and odors. If the air quality in your area is poor, you can replace the standard air conditioning filter with one that filters PM2.5 particles. This way, even when the external circulation is activated, there's no need to worry.

AQS stands for Air Quality System, which is a quite practical feature in car air conditioning. I've driven cars equipped with this function—it automatically monitors the outside air conditions. For instance, when encountering smog or exhaust fumes in traffic jams, it immediately switches to recirculation mode to prevent polluted air from entering the cabin. I've also noticed that it works in tandem with the air filter to effectively block PM2.5 and dust, keeping the interior fresh. Especially when driving in the city, it saves you the hassle of constantly adjusting the settings manually. Additionally, AQS enhances comfort during long-distance drives by ensuring smoother breathing and reducing fatigue. Most modern mid-to-high-end vehicles come with this feature, and I recommend car owners check if their model includes it—it genuinely improves daily commuting, particularly as air quality continues to worsen.

AQS stands for Air Quality Sensor system, which is the automatic control part of a car's air conditioning. In practical use, I've noticed that it relies on sensors located at the front of the vehicle to detect external pollutants. When levels of carbon monoxide or particulate matter exceed standards, it automatically closes the external air intake and switches to internal air recirculation. This not only reduces the entry of unpleasant odors but also extends the lifespan of the air conditioning filter. The system is typically connected to the car's infotainment system for intelligent adjustment, preventing human error. Having driven cars equipped with AQS several times, I find its best feature is the automatic mode switching on highways or in suburban areas, maintaining a consistently comfortable environment inside the cabin. However, it's important to note that regular maintenance, such as replacing the filter, is necessary to ensure efficiency. Overall, it's not just an additional feature but a practical tool that enhances the driving experience, especially beneficial for sensitive individuals.

When friends asked about AQS, I explained that it's an air quality management system for car air conditioning, which automatically senses external pollution and optimizes circulation. While maintaining the vehicle, I found this feature quite intelligent: if it detects high concentrations of dust or exhaust fumes, it closes the air intake and uses internal circulation to filter the air. This saves the hassle of manual operation, especially on busy roads. Many modern cars also add antibacterial coatings, working with AQS to enhance health protection. After understanding these, I advised average car owners to pay attention to the system indicator lights, check sensors promptly if issues arise, and avoid minor problems turning into major repairs.
