This project aims to quantitatively investigate people’s re-inhalation of their own exhaled air and inhalation of air exhaled from nearby people. Full-scale experiments will be conducted in a climate chamber ventilated with mixing air distribution. The methods of measuring concentrations of inhaled and exhaled air of a breathing thermal manikin will be systematically evaluated and the best method will be recommended. Two breathing thermal manikins will be used to simulate two seated persons. One of the manikin will exhale tracer gas N2O and another CO2. The N2O and CO2 concentrations inhaled by both manikins will be measured using INNOVA gas monitor and Fast Gas Meter. The influence of several important influential parameters will be examined, which include distance between manikins, positioning of body, positioning of head, breathing mode, supply flow rate, indoor air temperature, desk fan and desk slot.

This project will first establish a method that can accurately measure concentrations of inhaled and exhaled air of a breathing manikin and second reveal the fractions of one’s own exhaled air and air exhaled from nearby people in one’s inhaled air under different conditions. It will provide fundamental information for indoor ventilation design and for formulating intervention measures to ensure an acceptable inhaled air quality.
