关于室内冰上运动场馆热湿环境控制的模拟研究

Simulation Study on the Control of Heat and Humidity Environment of Indoor Ice Sports Stadium

人工冰场内存在大面积低温表面,其室内热湿环境控制远比普通公共建筑复杂。文章以冬奥会运动场地之一—国家体育总局冬季运动管理中心综合训练馆冰壶馆为例,讨论了冰场热湿环境特征和国内外对人工冰场的设计要求;列出了冰场室内热湿负荷的计算方法;并基于该场馆的暖通空调设计对室内环境进行了CFD模拟,为该场馆的热湿环境控制提出了降低送风含湿量、减小壁面发射率等优化措施,对同类项目具有参考意义。

With the 2022 Beijing Winter Olympic Games approaching,China has set off a boom in the construction and renovation of artificial ice rink.For this special public building with a large area of low-temperature surface,indoor thermal and humidity environment control is particularly important.Taking the curling hall,which is in the comprehensive training hall of Winter Sports Administrative Center of the General Administration of Sport of China as an example,this paper discusses the characteristics of thermal and humidity environment and the design criteria of artificial ice rink at home and abroad,lists the calculation method of indoor heat and moisture load of ice rink.By conducting a CFD simulation on the indoor environment based on the HVAC design of the stadium,the optimization measures such as reducing the moisture content of the air supply and decreasing the wall emissivity are put forward for the control of the heat and humidity environment of the venue,and it provides a reference for similar projects.
