This study considers the effects of ventilation system using the residential facilities to the transmission mechanism of indoor aerosol in the residential quarantine period space for infective diseases. This study focuses on the effect of the design of ventilation system on the internal flow field and the removal of contaminant pollution. A computational fluid dynamics software-FLUENT 6.2 is employed to simulate the internal airflow field of the residential quarantine period space. The Carbon dioxide (CO2) is adopted as the index of contaminant source. Three layouts of ventilation system are simulated and the airspeed field, the temperature distribution, and the contaminant distribution are analyzed to find the best ventilation system for the residential quarantine period space.
