Abstract

The purpose of this study is to analyze the Age of Air and the Local Air-change Effectiveness of by field measurement. The indexes of Age of Air and Local Air-change Effectiveness are used to analyze the local ventilation effectiveness of multiple locations and are mainly evaluated using the computational fluid dynamics (CFD) method. In this study, measurement of the Local Air-change Effectiveness was based on ASHRAE 129. The performance of Local Air-change Effectiveness and the dependence of the outlet location on Local Air-change Effectiveness were analyzed. The results showed that a greater air-change rate (ACH) may not guarantee better local ventilation effectiveness.
