A high-capacity filter-free ultrafine particle discount expertise developed by the Korea Institute of Equipment & Supplies is now being deployed (or is quickly to be deployed) at quite a lot of areas within the east Asian nation, together with subways, colleges, shops, and different giant public amenities.
The strategy dispenses with filters, as a substitute relying upon electrostatic forces – however managing to take action with out noticeable ozone era. By incorporating microfibre discharge electrodes and non-metallic carbon plates, says the group, the system operates with a low present but removes greater than 90% of ultrafine particles.
It successfully resolves the ozone challenge inherent in standard electrostatic strategies, with an ozone emission degree beneath 5 ppb—solely one-tenth of the focus discovered normally atmospheric situations.
KIMM says the expertise is especially efficient in giant areas, providing environment friendly air purification with out the drawbacks of conventional filter-based programs. Typical air purifiers with filters undergo from decreased airflow attributable to clogging and require pricey replacements. In distinction, this strategy doesn’t appear to hinder airflow, enabling the environment friendly purification of enormous volumes of air whereas allotting with the necessity for filter alternative, and so considerably lowering upkeep prices. In subway tunnel purposes, the system doesn’t require ducts, slicing manufacturing prices by greater than 30%.
The group says the expertise has been efficiently examined in subway tunnels at Seodaejeonnegeori Station, Oryong Station, and Jung-gu Workplace Station in Daejeon. A filter-free air air purifier designed for colleges can also be beneath CA certification course of and is about for wider deployment, with pilot installations presently underway in an elementary faculty in Busan. Moreover, a pilot take a look at within the HVAC system of a division retailer in Gyeonggi-do confirmed its advantageous particulate matter discount effectiveness in business settings.
Principal Researcher Dr. Hak Joon Kim of KIMM acknowledged, “This is the only technology that has fundamentally solved the ozone emission issue, which has long been a barrier to applying electrostatic methods indoors. Moreover, it is economically viable, reaching the break-even point within approximately three years after initial deployment.” He added, “We are preparing for broader adoption through the Designation of Innovative Products, KC Certification for electrical safety, and CA Certification for air purifiers.”
