One of the important parameters that dictate the effectiveness of ventilation system is air change rate. The air change rate provides overall effectiveness of ventilation in an enclosed space and it needs to be examined with age of air particles to decide about overall effectiveness. Age of air particles is the time air at a location spends inside the enclosure and hence provides useful information about presence of secondary flows. A range of tools have been used to predict local and global effectiveness of a typical ventilation system for a specific work environment. Computational fluid dynamics has proven to be an effective tool in this regard. The present work highlights various issues needed to keep in consideration while designing meeting rooms in busy manufacturing environments. Two meeting room configurations have been proposed and ventilation requirements for these enclosures have been estimated. Furthermore for two different fan configurations, interior enclosure conditions have been predicted.
