1 概述地铁车站和区间隧道的通风目的,主要在于使其温度下降或保持到乘客可以忍受的值,使站台层的吹风感尽可能保持最小值。实践表明车站本身送、排风系统的布置对通风效果颇有影响。列车驱动、行驶和刹车时,在地铁系统内相应产生大量热量。该列车功率是与列车长度和编组有关,此外还通过刹车损失产生 1 General The purpose of ventilation at metro stations and tunnels is to reduce or maintain the temperature of the metro station to a value that is acceptable to the passengers and to minimize the level of air in the station floor. Practice shows that the station itself to send, exhaust ventilation system layout quite influential. When the train is driven, driven and braked, a large amount of heat is generated in the subway system. The train power is related to train length and marshalling, plus braking losses
