BACKGROUND: There are two options when a
displacement ventilation system is employed. System (A) was originally q proposed
system but CFD data shows that the system (A) may cause temperature gradient
problem. The newly proposed system (B) resolved
the temperature gradient issue while maintaining design temperature, 74F.
