공기청정기의 현장적용평가를 통한 의료기관 내 공기오염물질 저감효율 파악

Abstract

According to a recent report on indoor air quality map conducted by the Ministry of Environment (2016-2017), the importance of indoor air quality in hospitals has emerged, with total airborne bacteria (82.3% and 149 cases) showing the highest number of facilities exceeding maintenance standards by contaminant. In particular, interest in the hospital environment is increasing as it is the living space of patients who are mostly vulnerable to pollutants. This study introduced an air purifier with decontamination function within the hospital facility, and the site application evaluation of the air purification system is given as a table of contents. The measurement items for the site application evaluation are fine dust, gross airborne bacteria, fungi, temperature and humidity, and the measuring equipment for each item is grimm dust spectrometer (model 1.108), Mars-100, and HOBO MX 1101. In the case of fine dust, the variation of fine dust can be seen through the measurement of the mining equation, and in the case of floating microorganisms (total airborne bacteria, bear Pangi) the impact method specified in the indoor air quality process test standards was collected, cultivated and quantified. Data were collected for conversion to CFU by counting after incubation of bioaerosol in case of temperature and humidity. The reduction efficiency is presented by comparing data before and after operation of the air purifier
