Abstract

The invention particularly relates to a ventilation control method for a public area of a subway station, and solves the problems that excessive fresh air exists and the system operation energy efficiency level is low in an existing ventilation control method for the subway station. The invention discloses the ventilation control method for the public area of the subway station. A ventilation system comprises an exhaust shaft, an exhaust fan, an air conditioning unit, a station hall air supply duct, a station hall air return and exhaust duct, a platform air supply duct, a platform air return and exhaust smoke exhaust duct and a carbon dioxide detection device. The ventilation control method is realized by adopting the following steps of: a, adopting an internal circulation mode or a fresh air adjusting mode according to the carbon dioxide concentration condition in a public area in a cold supply season; b, in the ventilation season, an only-discharging-not-feeding mode is adopted; c, when a fire disaster takes place in a station hall, a station hall smoke discharging mode is adopted; and d, when a fire disaster takes place in a station, a station smoke discharging mode is adopted.According to the method, a mechanical fresh air system is omitted, natural seepage air flowing in from an entrance and an exit of a public area is utilized, and energy consumption needed by ventilation is greatly saved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a ventilation control method for a public area of ​​a subway station. Background technique [0002] The subway station is an important urban infrastructure. It is currently in a period of rapid construction and rapid development. How to better meet the ventilation needs of the station, promote the efficient and reasonable operation of the subway station and reduce its operating energy consumption is the key point in the design and operation of the subway station. Concerns. The main function of the ventilation system of the subway station is to provide fresh air and remove excess heat to maintain the comfort of the station environment. The public areas on the hall level and platform level of subway stations have different functional characteristics from those in the office area and equipment area, and are only used for a short stay in the process of passengers getting on and...
