Research on Energy-saving of Adjustable Ventilation Platform Doors System in subway

The adjustable ventilation platform doors system in subway combines the advantages of platform-screen-doors system and the platform-bailout-door system, in result, shows energy saving effect in HVAC system. This research paper studied the ventilation effect by network simulation method using STESS software. Based on the ventilation simulation results, the energy saving effect of the system was analysed. The study objective is subway, which can be transformed into a network airflow model based on hydromechanics principles and subway structures. Thus, network simulation was applied in the subway ventilation research. Based on modelling, the relationship between ventilation volume and open area was found and discussed, which has never be down before. Moreover, the simulation results enable further analysis on energy consumption of subway HVAC system.
