초록

The purpose of this study is to analyze the removal performance of airborne contamination in a negative airborne infectious isolation room by conducting the field measurement and numerical analysis. This research investigates the pollutant distribution patterns by network ventilation simulation (macro analysis), CFD modeling (micro analysis) and field measurement based on three ventilation systems. An effective ventilation system is crucial to protect doctors, nurses and other healthcare workers from patients with infectious diseases. The results show that ventilation systems utilizing the low-level extraction technique are very effective at removing pollutants in the human breathing zone. A new clean isolation room ventilation strategy has been developed that employs two exhaust air grilles on the wall behind the bed, and is found to have the highest pollutant removal efficiency. The numerical simulation was verified by comparing its prediction result and the field measurement. Isolation room design strategies are formulated based on the results made in this study.
