The purpose of this study is to clarify the usefulness of a displacement ventilation air-conditioning system introduced into a multipurpose hall after CFD simulation and measurement. In the multipurpose hall of Kurume City, a displacement ventilation air-conditioning system equipped with a floor outlet had been adopted. A CFD simulation for the purpose of selecting an air condition system indicated the floor outlet system would be more effective for the design plan of the hall than a ceiling outlet system. Measurements for the purpose of determining the effectiveness and thermal performance of a displacement ventilation system were conducted after construction of the hall, and the obtained results for thermal performance and airflow distribution in the hall were consistent with the CFD simulation.
