摘要：

This　paper　analyzed　the　formation　of　piston-effect　and　the　air　flow　characteristics　in　subway.　Taking　an　operating　subway　in　Beijing　as　a　study　object,　the　calculation　results　of　SES　and　the　commercial　CFD　software　PHOENICS　(3.6.1)　were　compared　which　shows　well　accordance.　At　the　same　time　the　SES　results　and　the　field　measurement　results　were　compared　which　shows　well　accordance　too.　Then　the　result　of　study　was　applied　to　a　subway　HVAC　design　in　Beijing.　A　draft　plan　of　the　construction　of　ventilation　shaft　that　can　use　the　piston-effect　effectively　to　reduce　the　HVAC　energy　consumption　was　put　forward.
