As is well known, a moving person affects the stratification of indoor air and enhances the mixing in ventilated rooms with a displacement ventilation system. This paper describes the effect of moving object on the performance evaluation of displacement ventilation, by means of an experiment using a movable heated human model in a full scale room model. Distributions of air temperature and tracer gas concentration were measured to investigate the effect of the moving object′s direction, mode and speed on distribution of air in the room, and ventilation effectiveness. As a result of experiment, the moving object mode and speed showed a significant effect on the air temperature distribution and ventilation effectiveness.
