Discussion on ventilation design for underground parking links

This paper presents the architectural characteristics of the underground parking link which is a new type of urban underground road, and analyses the importance of the ventilation system design, especially the smoke exhaust system design for underground parking links. Meanwhile, combined with the existing domestic standards and the actual situation of the domestic underground parking link projects in recent years, the relevant ventilation design is discussed and analysed in terms of the building category, fire heat release rate, ventilation pattern and air duct materials of the underground parking link. The relevant advices about ventilation system design for the domestic underground parking link are put forward, which can provide a reference for the ventilation design for such projects in the future.
