항균처리를 한 공조기기의 항균성능 평가방법과 평가결과

Aluminum thin plate coated with epoxy resin containing about 20wt% brass powder, was applied to fins of heat exchanger. We carried out a series of detailed examinations to evaluate the anti-bacterial performance of the plate and heat exchanger (fan coil unit). In the presence of water or moisture, copper ions which have an anti-bacterial ability eluted from brass powder and showed sufficient effects on many kinds of bacteria. We also evaluated the anti-bacterial performance quantitatively by use of the index API (Anti-bacterial Performance Index) which has already been proposed by authors.
