What does AQS in car air conditioning mean?
1 Answers
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.
