1458-RP: MODELING PERSON-TO-PERSON CONTAMINANT TRANSPORT IN A MECHANICAL VENTILATION SPACE
TC 4.10 - Indoor Environmental Modeling

The transport of potential infectious agents from human bodies under the impact of ventilation airflow is not well understood. Existing studies are largely based on simple scenarios and thus the conclusions have limitations. For general health requirement as well as protecting susceptible individuals when there may be infected persons as contaminant sources, it is important to design the ventilation system carefully to avoid the spread of infectious agents. Besides, the SARS epidemic in 2003 and current concerns about the risk of an avian influenza (H5N1) pandemic, have made this study timely.

The results can help ASHRAE members and other professionals to better analyze and design healthier and safer indoor environments, especially for ventilation design. The commonly used ventilation modes in actual engineering are evaluated for their performances on inter-personal contaminant transport control. Results derived from this study would provide useful information to better understand the possible link between ventilation and contaminant transmission. The efficiency on controlling person-to-person contaminant transport and economical energy using should be balanced for actual application. Thus a guide on proper ventilation design would also benefit engineering practice.
