Abstract

The study discussed in this article evaluated the ventilation performance of three strategies for HVAC control for airborne infectious diseases induced by contaminated exhaled air from patients in an airborne infectious isolation room (AIIR). This article examines airflow path and airborne pollutant distribution by computational fluid dynamics modeling and field measurement. In hospitals, the risk of airborne virus diffusion mainly depends on airflow behavior and changes in direction caused by supply air and exhaust air locations. An improved isolation room ventilation strategy has been developed, and is found to be the most efficient in removing contaminants based on observations and simulation results from three ventilation systems.
