지하주차장 공기환경 개선을 위한 이오나이저의 적용효과 검토

Abstract

The main objective of this study was to verify a possibility of indoor air environment enhancement via actual operation of ionizer device. Two pollutants, benzene and toluene, were used as indicators for evaluating the air cleaning performance of ionizers. The test results show that negative air ions may provide the air cleaning effect which can be acquired by supplying 0.058-0.100(㎥/hr), 0.035-0.070(㎥/hr) ventilation. Another indicator of this test result, air cleaning factor(ACF) was also indicated that the impact of negative air ions is consistently maintained during the ionizer operation. In addition, according to experimental results, it was also found that removal efficiency of benzene was 2.1 times higher than that of toluene. From this research and existing literature, one can conclude that additional indoor air quality improvement can be expected by applying ionizers in ventilation system for underground parking facilities.
