          Abstract:

          Presents the overall design ideas of ventilation system of urban utility tunnel from the aspects of fire characteristics, ventilation system principle, ventilation node form, ventilation system operation mode and ventilation system control strategy. Analyses the key problems affecting the ventilation system design, such as the setting of ventilation nodes in different cabins, the selection of valves and fans at ventilation nodes and the control of variable working conditions in different cabins.
