摘要：

By using thermal dynamic simulation and CFD (computational fluid dynamics) techniques, thermal comfort and indoor contaminant distributions are analysed for a room with: (1) a conventional displacement ventilation system, (2) a cooled ceiling with displacement ventilation system, and (3) a cooled ceiling with ceiling air supply system. The numerical simulation results indicate that a cooled ceiling reduces the vertical temperature gradients while still maintaining the ventilation effectiveness much higher than one at a load of nearly 50 W/m2 floor area. By comparison, maximum cooling capacities of the three systems are discussed, specifically in respect to their thermal comfort performances.
