Metro Ventilation Systems

Metro sys­tems con­sist of under­ground sta­ti­ons as well as tun­nels, which con­nect the­se sta­ti­ons. Simi­lar to rail tun­nels, the ven­ti­la­ti­on sys­tem in the tubes is main­ly used to trans­port smo­ke gases out of the tun­nel in case of fire.

Under nor­mal ope­ra­ting con­di­ti­ons, the pis­ton effect of moving trains in the tun­nel is used to pro­vi­de fresh air to the tun­nel system.

The simu­la­ti­on of pres­su­re waves and air move­ments in under­ground sta­ti­ons is essen­ti­al for gua­ran­te­eing the com­fort of pas­sen­gers and pre­dic­ting the spread of smo­ke in the sta­ti­ons. In order to incre­a­se the sup­ply of fresh air, mecha­ni­cal ven­ti­la­ti­on sys­tems can be used for the tun­nel tubes and the stations.

In addi­ti­on to extrac­ting smo­ke and sup­ply­ing fresh air, ven­ti­la­ti­on sys­tems are used to pres­su­ri­ze stair­ca­ses or ele­va­tor wells and to pro­vi­de air con­di­tio­ning for tech­ni­cal rooms or public areas.
