The air distribution of air-conditioned room in the pattern of personalized ventilation and stratum ventilation was simulated respectively with the Fluent airpak numerical simulation software in this paper. And the indoor thermal environment of the two ventilation modes was comparative studied. The following conclusions could be obtained. Obvious draft sensation wouldn't be produced, as long as the air velocity of the two ventilation modes was controlled in a certain range. The value of air

The mean age of air of human breathing zone in the pattern of personalized ventilation was less than that in the pattern of stratum ventilation. However, the mean age of air in the plane of human breathing zone (y=1.1m) was less. The temperature difference between head and foot of personalized ventilation was less than that of stratum ventilation. In the pattern of personalized ventilation, the temperature distribution was better as well as thermal comfort.
