지하역사 공기조화기 전처리 필터용 축류형 사이클론의 수치해석 및 실험적 평가 연구

Typical Korean subway HVAC (heating, ventilation and air-conditioning) system uses three types of filter(auto suction filter, electrostatic precipitator, auto cleaning demister) as pre-filter. These kinds of filters require high maintenance and effort. To reduce such disadvantages, here we suggest axial-flow cyclone as a new type of pre-filter which has low maintenance, low effort and constant performance which is favorable. Numerical and experimental study are progressed for its evaluation.
