Case 2:
air supply system
using circular ceiling diffusers
Choosing air distribution systems in school classroom
by using CFD simulation  data
BACKGROUND: There were two options when classroom ventilation system was employed. Case 2 was the originally  proposed ceiling diffuser system but engineers employed another type of air supply system: air supplied with unit ventilator. CFD data shows the difference between Case 1 & 2 for temperature, CO2, and draft distributions.
