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。
Gym indoor thermal environment not only to meet the needs of the human body, but also to meet the rational use and energy conservation needs. CFD technology is used to simulate and predict the airflow in a large gymnasium, and the distribution of physical quantities such as speed and temperature of indoor air in a gymnasium is obtained. It is found that the wind speed at the location of the dual influence zone of the air outlet is large, which affects the thermal comfort of the audience. The distribution of the velocity field formed by the wraparound air around the area above the stadium is evenly distributed between 0 and 0.5 m / s, Competition requirements; around the way around the air can be in the audience less time by arranging the audience to sit, to achieve energy-saving emission reduction purposes. The research results of air conditioning units on indoor thermal environment in stadiums will lay the foundation for non-uniform thermal environment research in stadiums and provide theoretical support for energy-saving measures in stadiums.
