Abstract
This study explores the spatial relationships of supply and exhaust air ventilation in patient corridors. An actual hospital was used to observe the transport of synthetic aerosols in a 31.5m patient corridor. The aerodynamic behaviour of aerosol within the patient corridor was observed with respect to particle size, time and distance relative to the directional airflow and air change rate of the existing HVAC system. Computational Fluid Dynamic (CFD) methods used to create a modified supply-exhaust air system configuration that has shown to reduce aerosol transport distance more than 60% and reduce average aerosol concentration roughly 30% without increasing air change rate.
