CFD ANALYSIS OF AIRFLOW CHARACTERISTICS IN OFFICE ROOM WITH TASK AIR-CONDITIONING AND NATURAL VENTILATION

The performance of indoor airflow for the office room with the hybrid air-conditioning system has beeninvestigated by means of CFD analysis. The hybrid air-conditioning system is composed of under floorair supply outlets for task zone and the natural ventilation openings for ambient zone. The measureddata (Kotani et al. 2006) at the office room in existence was used as the boundary condition of the flowrate of each natural ventilation opening and task flow outlets for CFD.
