The results show that man's movement affects air pressure, air velocity and contaminant distribution, while the impact on air temperature can be ignored. Based on the simulation, concludes that the impact of man's or equipment's movement should be taken into account and reduced in air pollution control in crucial medical rooms, and a dynamic CFD simulation method is preferred in this condition.
