실외공간 적용 청정공기 공급장치 성능평가

초록

A novel particulate matter(PM) outdoor reduction technology was developed, which we refer to as DEMC (De-dusting, Ever-lasting efficiency, Maintenance-free Custom-fit filter) technology. The most impressive feature of this technology is that its performance is maintained even after use for prolonged periods outdoors, which dramatically reduces filter replacement costs. An authorized testing institute confirmed the particle removal performance of DEMC technology. To evaluate the particulate matter removal efficiency of DEMC in an outdoor environment, a device was installed in open and closed areas of a BRT bus station. PM10 concentrations at these stations during DEMC operation were 40 % and 18 % lower, respectively, than outdoor PM10 concentrations.
