Abstract

The impact of sinusoidal airflow with periods of 16s, 8s and 3s produced by a personalized ventilation (PV) system on the personal exposure and the concentration of airborne droplets in the inhalation zone of a seated thermal manikin in an office is investigated in this study. A droplet generator is used to produce airborne droplets to simulate expiratory activities. And the real-time concentration of airborne droplets is measured by an aerosol spectrometer. This study reveals that sinusoidal airflow with periods of 8s and 3s from PV can effectively prevent airborne droplets entering into the inhalation zone and plays an important protection role. It can be seen that PV with proper dynamic airflow can be a potential method to improve the indoor air quality.
