Supply-only ventilation

Nowadays, indoor air quality has become a major concern. Regarding the fact that people spend most of their time indoors, it is necessary to study the performance of the ventilation system in order to limit the risks on occupants’ health. This study evaluates the ventilation effectiveness of supply-only ventilation (SOV) and extract-only ventilation (EOV) in terms of air exchange efficiency and contaminants removal effectiveness. These indicators are measured as function of air change rate and inlet/outlet devices positions using the gas tracer technic.
