摘要
Abstract
The PSD system of a metro station would hinder the diffusion of tunnel heat,and different heat exhaust ways has different effect on tunnel temperature. The impact of OTE and UPE to heat exhaust of tunnel has been cal-culated by numerical simulation. The simulation results indicate that open UPE will increase volume of exhaust fan, as well as decrease the average temperature of tunnel;at the same time,by analysing the air volume and tempera-ture of each vent,it is suggested that the upstream and bottom vents should be bigger for a more effective heat ex-haust efficiency.关键词
