摘　　要：体育馆室内合理热环境既要满足人体需求,也是满足合理地使用与节约能源的需要。利用CFD技术对大型体育馆气流组织进行模拟和预测,得到体育馆室内空气的速度、温度等物理量分布情况。研究发现:处于送风口双重影响区域的位置风速较大,影响观众的热舒适性;体育馆比赛区域上方四周环绕式送风形成的速度场分布均匀,处于0~0.5 m/s之间,可满足比赛要求;四周环绕送风方式可在入场观众较少时通过安排观众集中就坐,达到节能减排的目的。空调机组对体育馆室内热环境营造研究结果将为体育场馆非均匀热环境研究打下基础,为体育馆节能措施提供理论支持。Reasonable indoor thermal environment of a gymnasium can meet the needs of the human body and energy saving.CFD technology is used to simulate the air distribution at the large gymnasium. Temperature and velocity distribution on different sections of the gymnasium are obtained. According to the results,it is found that the wind speed is large if the area is impacted by the double outlet,the thermal comfort of the audience is bad and can＇t meet the requirement; air velocity distribution around the playing area in the stadium is between 0-0. 5m/s and meet the competition requirement; energy saving is done by a centralized seating arrangements when there are fewer spectators. The results of indoor thermal environment of a Gymnasium by air-conditioning unit will lay the foundation for the study of non-uniform thermal environment and provide theoretical support for energy-saving at the gymnasium.
