Design and Analysis of Ventilation in Underground Cable Tunnels

Natural ventilation and mechanical ventilation were compared.The running modes of ventilation in underground cable tunnel were introduced and the reasonable ventilation mode was selected based on the location of tunnels.And problems should be paied attention to in design were also pointed out.It focused on the analysis of ventilator room choosing and ventilation sub-areas distinction,heat cold and ventilation quantity calculation,air velocity control in tunnel,art control and so on.It can be referenced for the similar project.
