【中文摘要】 采用数值模拟,考虑在过渡季节结合屏蔽门与开式系统的优点,通过屏蔽门上设置可控风口充分引进列车运行的活塞风来加强车站与室外的通风换气,并分析车站的速度场及温度场,最后判断这种新模式具有一定的节能效果,为以后的地铁车站在过渡季节的空调设计也提供了参考价值。 【英文摘要】 Considering the advantages of PSD and open systems in the transitional season,in this paper,we set the controllable tuyere on the PSD by which can fully absorb piston wind to reinforce the ventilation between stations and outdoor, And analysis velocity field and temperature field of the station. Finally, we find this new model has a certain energy-saving effect,which provide reference value for future air-conditioning design in the transition season. 【中文关键词】 可控风口; 开式系统; 过渡季节; 屏蔽门 【英文关键词】 controllable tuyere; Open-system; transition season; PSD
