Hyundai develops air-con tech to maintain clean air in vehicles

Hyundai Motor Group has revealed a new system to improve the quality of air in vehicles. The three new air-conditioning technologies – ‘After-Blow’, ‘Multi-Air Mode’, and ‘Fine Dust Indicator’ will be introduced initially on select models in Korea and expand to upcoming Hyundai, Kia and Genesis vehicles worldwide.

‘After-Blow’ is designed to dry the condensate on the evaporator and suppress mold growth in the air-conditioning system.

After the engine is turned off, the condensate on the evaporator drains naturally for about 30 minutes, ‘After-Blow’ activates for 10 minutes to dry the evaporator and any condensate left in the air passage. The air-con system automatically allows influx of outside air during this time to prevent humidity build-up.

The technology uses an intelligent battery sensor (IBS) to monitor the battery and stops functioning when the battery is low. It also de-activates when the air conditioning system is not in use for a certain period, or when the outside temperature is low.

‘Multi-Air Mode’ uses multiple vents for air conditioning and heating to create a ‘more pleasant indoor environment with gentle wind’.

When this mode is activated, the air is dispersed to multi-air slots in the driver and passenger seats in addition to the normal air vents. The overall wind volume remains the same, but the dispersion reduces direct air contact.

‘Fine Dust Indicator’ measures the air inside the vehicle in real time and delivers digitised information, allowing the driver to better manage the air quality.

The indicator displays the concentration and pollution level of ultrafine particles.

If the level of ultrafine particles exceeds 36 μg/m3 while the function is active, the air-cleaning mode will run to purify the air. The air-cleaning system automatically sets the air volume between 3 and 8 and switches to air-recirculation mode and activates the air conditioning system to reduce indoor humidity. If the air does not improve in air-cleaning mode, it can serve as a reminder to replace air-conditioner filters or to clean contaminated seats and mats.
