Abstract

The purpose of this study is to reduce the contaminants (total volatile organic compounds (TVOCs), fine particle, odor and total airborne bacteria) during cooking process in cooking chamber, and to decrease the health damage in indoor space that has bad work environment. In order to solve the shortcomings of existing air purifiers and remove all kinds of pollutants effectively, this study focused on the development of indoor air purifiers which are made of bar type. Bio-ceramics filter which combines activated carbon and loess. The air cleaners developed with 4 measuring items including TVOCs, particulate matter, complex odor and total airborne bacteria were measured comparing their pre-service test to their post-service test after a period of time. The measured results showed higher removal efficiency of 91.02% as the concentration of TVOCs was reduced from $2,500{\mu}g/m^3$ to $223{\mu}g/m^3$. Second, the particulate matter removal ratio was 97.51% efficient with average concentration of $26.68{\mu}g/m^3$. Third, the odor showed 95.20% reduction as air dilution ratio averaged out at 144. Last, total airborne bacteria was eliminated by over 94% showing the changeable concentration from $787{\sim}814CFU/m^3$ to $47{\sim}40CFU/m^3$. In addition, the removal rate of harmful pollutants is excellent, and it is expected that the environment of the existing poor cooking room will be greatly improved by using the developed air purifier in combination with the ventilation device and the stove hood.

본 연구의 목적은 조리과정에서 발생한 총휘발성 유기화합물질, 미세먼지, 악취, 총부유세균 등의 오염물질들이 조리실내로 분산되어 실내공간이나 조리업 종사자에게는 나쁜 냄새나 작업환경 및 건강피해를 감소하고자 하는 것이다. 이를 위해 기존 공기청정기의 단점을 보완하고, 반영구적이며, 각종 오염물질을 효율적으로 제거하기 위하여 활성탄과 황토를 결합한 바이오세라믹 필터를 bar type으로 제작한 실내용 소형 공기청정기 개발에 중점을 두었다. 측정항목은 총휘발성 유기화합물, 미세먼지, 복합악취, 총부유세균 등 모두 4가지 항목으로 개발된 공기청정기 가동 전과 일정시간 가동 후를 비교하여 측정하였다. 측정결과, 총휘발성 유기화합물의 농도는 평균 $2,500{\mu}g/m^3$에서 $223{\mu}g/m^3$으로 약 91.02%의 높은 제거효율을 보였으며, 미세먼지의 제거율은 평균 농도가 $26.68{\mu}g/m^3$로서 97.51%의 우수한 제거효과가 나타났으며, 복합악취의 희석배수를 측정한 결과 평균 144로 평균 95.20% 감소하였다. 또 총부유세균은 초기 농도가 $787{\sim}814CFU/m^3$에서 $47{\sim}40CFU/m^3$로 약 94% 이상 제거되는 것을 확인하였다. 결론적으로 개발되어진 공기청정기의 바이오세라믹 필터는 오염물질을 제거하는데 우수한 제거효과를 나타냈다. 따라서 공기청정기를 조리실내에서 환기장치와 렌지후드를 병행하여 사용하면 기존의 열악한 조리실 내의 환경이 크게 개선되어질 것으로 사료된다.
