Effects of Outdoor Air Pollutants on Indoor Environment Due to Natural Ventilation

This study measured ventilation volumes and particle concentrations in indoor environments with open windows doors. In addition, the effect of airflow mode air conditioner on volume concentration variations was also measured. The fan could only provide approximately 43% during design phase. amount differed depending opening area increased by multiple or doors, even when same. No significant change rate observed, although expected to promote room set blow mode. It confirmed that both 0.3 1 μm particles enter through gaps around Although most 5 were from outdoor air, operated mode, removal performed filter. use medium-performance HEPA filters is remove smaller particulates.
