Subway station public area environmental control system

Abstract

The invention discloses a subway station public area environmental control system. The subway station public area environmental control system comprises an equipment large-end environmental control machine room, an equipment large-end smoke exhaust fan, an equipment large-end exhaust shaft, an equipment small-end environmental control machine room, an equipment small-end smoke exhaust fan, an equipment small-end fresh air shaft and an equipment small-end exhaust shaft. A subway station public area is connected with the equipment large-end environmental control machine room and the equipment small-end environmental control machine room through public area air supply pipes, and station hall air supply and platform air supply are achieved; an equipment large-end public area air return pipe isconnected with the equipment large-end smoke exhaust fan and the equipment large-end environmental control machine room, and station hall air return and smoke exhaust and platform air return and smoke exhaust are achieved; and an equipment large-end public area air return / exhaust pipe is connected with the equipment small-end smoke exhaust fan and the equipment small-end environmental control machine room, and station hall air return / exhaust and smoke exhaust and platform air return / exhaust and smoke exhaust are achieved. According to the subway station public area environmental control system, outdoor fresh air is treated through a combined air conditioner box in the small-end environmental control machine room and is fed into the public area, the area of a large-end fresh air shaft is reduced, and the influence of a ventilation pavilion on the ground landscape is reduced.

Description

technical field [0001] The invention relates to the technical field of subway station ventilation, in particular to an environment control system for a public area of ​​a subway station. Background technique [0002] The internal environment of the subway should be controlled by the environmental control system, which should ensure that the air quality, temperature, humidity, airflow organization, airflow speed, pressure change and noise of the air environment inside the subway can meet the physiological and psychological conditions of the personnel and the normal operation of the equipment. need. [0003] The ventilation and air-conditioning system in the public area of ​​the subway station is an environmental control system that serves the public area of ​​the subway station hall and platform, and ensures the fresh air, temperature and humidity requirements for personnel staying in the area for a short period of time. [0004] In the existing technology, the most adopted ...

Problems solved by technology

As a result, the air supply and exhaust pipes leading from the environmental control room to the public area at the large end of the equipment need to pass through a large number of equipment management rooms, especially the distribution station. The length of the air system in the public area is as high as more than 200 meters, which reduces the environmental control. The operating effect of the system, while the operating cost of the system is also high

[0007] 2. The wind pavilion at the subway station is an important factor affecting the effect of the ground landscape. In the traditional design, the area of ​​the wind pavilion at both ends of the station is relatively large, which has a serious impact on the ground landscape

[0008] 3. The symmetrical layout of the environmental control system will increase the difficulty of pipeline integration for designers. Sometimes, in order to meet the elevation requirements of electromechanical pipelines, the net height of the building will be increased, and the civil construction investment will be indirectly increased.
