Hyundai Motor Company and Kia Corporation have introduced three new temperature control technologies designed to enhance passenger comfort and improve energy efficiency in vehicles. The technologies, showcased at the 'Heat Tech Day' event in Seoul, South Korea, include the Nano Cooling Film, Radiant Heating System, and Metal-Coated Heated Glass. These advancements are poised to redefine in-vehicle climate control, particularly in the era of electric vehicles.
The Nano Cooling Film is one of the standout innovations, significantly reducing the interior temperature of vehicles. When applied to vehicle glass, this advanced film can lower the internal temperature by over 12°C, as demonstrated in tests where vehicles equipped with the film maintained an interior temperature of 36°C compared to 48.5°C in vehicles without it. The film blocks infra-red radiation and allows heat to escape from inside the vehicle, providing a more comfortable cabin environment while reducing the need for air conditioning.
In addition to the cooling technology, Hyundai and Kia have introduced the Radiant Heating System, which quickly warms passengers during cold weather. The system uses a film-type heating element that emits radiant heat towards passengers' legs, warming them within three minutes. This system is not only fast but also energy-efficient, potentially conserving up to 17 percent more energy compared to traditional heating methods, making it especially beneficial for electric vehicles by extending their driving range in winter conditions.
Another innovation is the Metal-Coated Heated Glass, a world-first 48V system designed to quickly remove frost and moisture from windshields, enhancing visibility and safety. The system can completely defrost glass surfaces within five minutes at temperatures as low as -18°C, operating up to four times faster and using 10 percent less energy than conventional methods. Additionally, the metal coating on the glass can block at least 60 percent of solar energy, further reducing the cabin's cooling requirements.
