Research on underground railway ventilation and air conditioning system scheme with adjustable ventilated platform doors

Based on the screen door, closed and open systems, establishes the new underground railway ventilation and air conditioning system with adjustable ventilated platform doors. Simulates and analyses the operation modes and energy saving effect of this system applied in the extremely cold, cold, hot summer and cold winter regions. The results show that this system can meet the specification requirements, reduce energy consumption and improve the environment around passengers.
