大型开放式体育馆座椅通风换热性能研究

Study on Ventilation and Heat Transfer Performance of Seats in A Large-scale Open Gymnasium

针对大型开放式体育场馆的环境特点,以北京市某大型开放式体育场馆的观众座椅为研究对象,旨在提高馆内座椅在夏季与冬季的通风换热能力,结合FLUENT软件,在制热制冷工况下分别对座椅的温度场进行模拟研究。对比分析在冬夏季节,传统送风方案与座椅送风方案在不同出风速度、不同出风角度时温变效果,研究结果表明,采用较大出风角度和出风速度的座椅送风方案比同条件下的传统送风方案能更有效地提高大型开放式体育场馆通风换热的舒适性。

According to the environmental characteristics of large-scale open stadium,the spectator seats of a large-scale open stadium in Beijing were taken as the research object to improve the ventilation and heat transfer capacity of seats in summer and winter.Combined with FLUENT software,the temperature field of the seats was simulated under heating and cooling conditions.In winter and summer,the temperature change effect of the traditional air supply scheme and the seat air supply scheme at different outlet speeds and angles are compared and analyzed.The results show that the seat air supply scheme with larger air outlet angle and air outlet speed can effectively improve the ventilation and heat transfer comfort of large-scale open stadium compared with the traditional air supply scheme under the same conditions.
