Shielding door-based urban metro station ventilating method and system

Abstract

The invention discloses a shielding door-based urban metro station ventilating method and a shielding door-based urban metro station ventilating system. The method comprises the following steps: in the air-conditioner-use season, a station public area is isolated from a running tunnel; the air temperature and humidity of the station public area are guaranteed through a station public area air conditioning system, and ventilation of the running tunnel is guaranteed through a running tunnel ventilating system in the running tunnel; and in the non-air-conditioner-use season, the station public area communicates with the running tunnel as required, and ventilation from the station public area to the running tunnel is realized according to a train piston effect. The system comprises the station public area air conditioning system, the running tunnel ventilating system and a shielding door for isolating the station public area from the running tunnel; hanging plate tuyeres (1) and a control actuation device (2) are arranged on the shielding door; and the control actuation device (2) controls the hanging plate tuyeres (1) to be closed or opened so as to isolate the station public area from the running tunnel or communicate the station public area with the running tunnel.

Description

technical field [0001] The invention belongs to the technical field of subway station ventilation and air conditioning, in particular to an energy-saving and simple screen door-based ventilation method and system for urban subway stations. Background technique [0002] Because the underground railway has the characteristics of high speed, safety, punctuality and large passenger capacity, it is the most effective means to solve the traffic congestion in modern cities. Therefore, dozens of large and medium-sized cities in the world have widely used the subway as the main public transportation. Since subway platforms and tunnels are mainly located underground, heat dissipation and cooling will inevitably consume a lot of energy. At present, in addition to the use of mechanical ventilation as the main means of subway heat removal and cooling in cold regions in the world, air conditioning is used as the main means of subway environmental control in most tropical and subtropical r...

AI Technical Summary

Problems solved by technology

However, in the non-air-conditioning season, due to the isolation effect of the screen door, the piston wind cannot be used for ventilation in the public area of ​​the station, and the mechanical ventilation system of the station still needs to be operated, resulting in increased energy consumption of the ventilation system. This is the disadvantage of the screen door system

[0004] Therefore, the problems in the existing technology are: the piston wind cannot be used for ventilation in the non-air-conditioning season of the public area of ​​the station, an additional ventilation system is required, a large increase in energy consumption, and the system is complicated
