Abstract：The influence of air flow organization changes in small meeting rooms on thermal comfort is studied.The temperature,velocity,pressure and predicted average voting value(PMV)indicators under three design schemes of air conditioning outlet angles are simulated and analyzed through Airpak simulation software.The results show that the horizontal air outlet scheme has the best thermal environment effect,with a PMV less than 0.5,meeting the human body's thermal comfort requirements.The temperature distribution is relatively uniform and the wind speed design is reasonable.The 15° increase plan has a local blowing sensation and uneven temperature distribution.The 15° decrease plan makes people feel colder near the air outlet,and the overall spatial distribution is uneven.The research provides a reference for the optimal design of air flow organization and the rationality of spatial layout in the meeting room.
