This study examines the way of utilizing a ceiling fan for airflow control in a large air-conditionedroom. Although it seems that CFD simulation is useful in predicting the airflow around a ceiling fan, modeling of a ceiling fan as a body of rotation is very complicated. Therefore, in this study, airflow of a ceiling fan is modeled as boundary conditions of air velocity data measured near the ceiling fan. In this paper, the measured airflow pattern around a ceiling fan is compared with the CFD simulation result using the airflow model of the ceiling fan, in order to examine the validity of the airflow model. The CFD result was in good agreement with the measurement result concerning the average of air velocity.
