VENTILATION DESIGN OF UNDERGROUND PARKING AREA IN A NEW BUILDING USING CFD

CFD를 이용한 신축건물 내 지하주차장의 환기설계

With the recent increasing demand on the high-performance buildings, there has been a rapid growth in the application of the Computational Fluid Dynamics to the Building design. The conceptual ventilation design of the underground parking area currently under construction is validated using the CFD-ACE+. It has been found that the conceptual ventilation design quantitively satisfies the legal standards. However, the highly concentrated region of CO is predicted. The positions and blowing directions of ventilating lane are changed based on the previously predicted concentration distributions. The highly concentrated region of CO is slightly reduced, but not much change has been observed. Two more fang are installed and the positions and blowing directions of the fans are modified so that the highly concentrated region of CO is minimized.
