Analysis of the Velocity Distribution in the Plenum Box with Various Entries

The ventilation system plays a crucial role in every building. Proper design and optimization of its operation increase the comfort users due to efficient air exchange at same time control velocity rooms. aim this paper is analysis effect plenum box entry on profile concerning diffuser face panel. This issue may sometimes be ignored stage but can significantly affect airflow from consequently risk draft. results PIV experimental measurements numerical simulations various entries (top side) were investigated study. used develop mathematical models, which then assess localization spigot operation. was carried out boxes with panel composed square grid perforations. Analyses show that both way distribution inside under simulated diffuser.
