Abstract

The purpose of this study is to investigate the effect of supply air return from the HVAC system on indoor air quality. We discuss the structure of the formation mechanism in local pollutant concentration distributions using various indices on the ventilation efficiency of a local domain in 3 rooms with different layout of the exhaust outlet location. As a result, when the percentage of the return air at the supply inlet becomes large, visitation frequency of pollutants on a target local domain increases exponentially, and then the averaged concentration of the pollutants of the local domain also increases exponentially.
