Ventilation system and method for subway equipment room

Abstract

The invention provides a ventilation system and method for a subway equipment room. The system and the method used for solving the problems of complex pipelines, large space requirement, inconvenientmaintenance and poor comfort of an all-air system. A fresh air machine of the ventilation system communicates with an air supply drying pipe, the air supply drying pipe communicates with air supply branch pipes, the subway equipment room communicates with at least one air supply branch pipe, and the air supply branch pipes are provided with air supply openings in the subway equipment room; an exhaust fan communicates with an exhaust air drying pipe, and the exhaust air drying pipe communicates with an exhaust branch pipe; the exhaust branch pipe communicates with a corridor, and a centralizedexhaust port is arranged in the corridor; the air exhaust branch pipe communicates with the subway equipment room provided with a gas fire extinguishing system, and a low-level air exhaust port is arranged in the subway equipment room; the air supply branch pipes and the air exhaust branch pipe are provided with electric control switch valves; and a multi-connection air conditioner is installed ina plurality of subway equipment rooms. The system and the method simplify and optimize the ventilation system for the subway equipment room, more accurately control the room air environment, reduce the pipeline size, reduce the space height and reduce the civil engineering scale.

Description

technical field [0001] The invention belongs to the field of underground space ventilation and disaster prevention, in particular to a ventilation system and method for subway equipment rooms. Background technique [0002] At present, the domestic subway ventilation system generally adopts the all-air ventilation system, such as figure 1 As shown, the combination of combined air-conditioning unit and return / exhaust fan is used to ventilate the underground station. However, as more and more subway stations are built and put into use, the disadvantages of the all-air system are gradually revealed, mainly in the following aspects: [0003] 1. At present, the pipelines in domestic subway stations are intricate and various, especially the ventilation pipelines occupy the largest space; in order to achieve the purpose of energy saving, the subway ventilation system sets up air conditioners for different types of equipment management rooms, according to differences in usage time, ...
