Air Quality in a Semi-enclosed Public Transport Interchange Station in a Comprehensive Transit Hub
-
摘要: 为了提高城市交通系统内部环境空气质量,以北京某综合交通枢纽的半封闭公交换乘站为研究对象,选取CO为主要污染物,通过对枢纽内不同时期的通风系统、车流、人流量及空气质量进行现场调研,以实测数据为边界条件,运用大涡模拟技术对不用通风运行模式下交通客流高峰期和低谷期枢纽内0.8 m和1.6 m高度处的空气质量进行分析.研究结果表明:除了车辆尾部区域相同位置在上班高峰时期的ρ(CO)是低谷期的2倍;在通风系统不运行情况下,枢纽内空气质量在5~10 min会达到对人体有害的程度.为达到室内空气质量相关标准要求,枢纽内通风系统必须在高峰期连续运行而低谷期可以采取间歇运行的方式.Abstract: In order to improve the indoor air quality of city transport system,the authors had selected a public transport interchange station in a comprehensive transit hub as a research object. Carbon monoxide was selected as the main pollutant for description of air quality. Ventilation systems,bus traffic and passenger flow,air quality had been investigated by on-site survey. Large eddy simulation technology had been used to analyze indoor air quality of public transport interchange station. The boundary conditions were determined according to the measured date. Indoor air quality results at heights of 0. 8 m and 1. 6 m under different time periods and operating conditions of public transport interchange station were calculated. Time periods include the peak hour and trough hour.Resultshave shown that carbon monoxide concentration in peak hour is about twice than that in trough hour in most area except the rear area of the vehicle. Air quality would reach the harmful degree within 5 to 10 minutes if the ventilation system is not operating. The ventilation system should be operated during the peak hour and intermittent operation mode can be adopted during trough hour in order to meet the requirement of air quality standards.
