동결을 이용한 유해한 실내 오염물질의 정화방법 VIDEO: Harmful indoor pollutants can be transformed into clean air by FREEZING them

Harmful indoor pollutants can be transformed into clean air by FREEZING them (and the technique could reduce air impurities by 99%)

         The diagram shows polluted air being circulated through the cryogenic tube to around 18°C, the particles 

         clump together and fall to the bottom allowing clean air to pass through

Researchers find way to remove pollutants by freezing air in 'condenser tube'

Finer particles stuck together in tube before dropping out as clean air

Some technologies to purify air exist, but they can be inefficient and expensive

This could pave way for humidifiers and air con units to clean polluted indoor air

동결을 이용한 유해한 실내 오염물질의 정화방법    유해한 실내 오염물질은 동결시키므로서 클린한 공기로 변환될 수 있다(이 기술은 공기 불순물을 99%까지 감소시킬 수 있음) 연구자들은 '콘덴서 튜브'에서 공기를 얼려서 오염물질을 제거하는 방법을 찾고 있다. 깨끗한 공기로 떨어지기 전에 더 단단한 입자가 튜브에 함께 고착됨 공기를 정화시키는 기술이 존재하지만, 그것들은 비효율적이고 비싸다 이 기술은 가습기와 공기정화기가 오염된 실내 공기를 청소하는 길을 열어줄 수 있는 계기가 될 것이다. 유해한 실내 오염물질을 동결하는 것은 가정과 사무실의 공기의 질을 99%까지 크게 향상시킬 수 있다고 전문가들은 말한다. 오염 공기는 -18°C 이하로 빠르게 냉각되는 극저온 튜브를 통해 응축되어 깨끗한 공기로 변할 수 있다는 사실을 연구원들이 발견했다. 황기철 콘페이퍼 에디터 큐레이터 Ki Cheol Hwang, conpaper editor, curator

Freezing harmful indoor pollutants could drastically improve the air quality in our homes and offices by 99 per cent, experts say.

Polluted air can be transformed into clean air by condensing it through a cryogenic tube, which rapidly cools the air to below -18°C, researchers found.

          In cities with major air pollution, the outdoor air is often exchanged with the indoor air via windows and other 

          openings. When outdoor air quality is bad people stay indoors more, meaning they are still impacted

Cryogenics freezes haze particles causing them to clump together and fall to the bottom of the tube, allowing the clean air to pass through the other side.

The study aimed to address the severe effect that hazardous outdoor air pollution was having on indoor air quality.

It is thought to lead to more than three million premature deaths worldwide every year.
