Development of ventilation design strategy for effective removal of pollutant in the isolation room of a hospital

For the investigation of airflow and pollutant distribution in the isolation room of a hospital, objective measurements and CFD modelling based on three ventilation strategies have been carried out. As a result, the low-level extraction technique appears very effective in removing pollutant at the human breathing zone compared to the ceiling level extraction technique, the best ventilation is the one with the supply air grilles delivering a laminar flow of outside air to the occupant with minimal entrainment of the air in the room.
