기류분석을 통한 종합병원(외래)진료부의 공기 감염 개선 연구

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate and possibly prevent airborne infection in general hospitals The CFD analysis of emergency and outpatient departments was summarized as follows; First, assessment on the first floor of the general hospital revealed that indoor exhaust air was not ejected in concurrence with the supply air, which could lead to an air shutdown. Second, CFD analysis confirmed the results of the actual survey that air congestion and inflow into other spaces may increase the probability of airborne infection. Third, the CFD analysis reflecting the improvement plan established that when the exhaust in the lobby was increased and the door was opened, there was difficulty in air control. When all the doors were closed, pressure differences occurred on the left and right sides of the lobby. Particularly, air flow may be stagnant in the stairwells and corridors, or an introduction of air in the lobby. Further installation of the front rooms, doors and exhaust outlets also enhanced the control of air flow between spaces, and flow through staircases and elevators. Therefore, it is thought that the separation of space and the proper location of exhaust could be the most effective way of controlling airflow in hospitals. In addition, it is necessary to put in place measures to reduce the possibility of airborne infection by applying each of the exhaust systems by space.
