摘要
研究目的:针对大连的气候特点及大连地铁的具体情况,对大连地铁通风空调系统方案进行研究与分析,并根据SES地铁环境模拟软件的计算结果,选择较为经济合理的通风空调系统方案及运行模式。研究结论:大连地铁通风空调系统采用机械通风,开闭式运行相结合的方式。(1)充分利用自然冷源,依靠列车运行所产生的活塞风对车站和区间隧道进行通风换气、冷却降温,可减少通风设备的开启时间,达到节能降耗的效果;(2)针对大连夏季室外空气相对湿度较高的特点,夏季最热月对送入车站公共区的室外空气采取除湿措施,可为乘客创造一个更为适宜的车站内部空气环境;(3)车站通风设备与区间通风设备相互兼用,根据不同的工况相应转换运行模式,可提高设备使用率,降低设备初投资及维修保养费用。
Research purposes： According to the weather characteristics of Dalian and its specific situations of the subway, the schemes for ventilation and air conditioning system were researched and analyzed. The scheme and operation mode of ventilation and air conditioning system were selected on the base of the calculation results obtained with SES software for simulation of subway environment. Research conclusions：The mechanical ventilation system with open and close operation mode was used for the Dalian subway. The ventilation to the station and sectional tunnel and cooling temperature were achieved by making full use of natural cooling source and the air produced by piston in order to reduce the operation time of the ventilation device as much as possible and save the energy. According to the high air humidity of Dalian in summer, the air pumped into the public area of the station was dehumidified in the hottest months to make the environment more comfortable for passengers. The ventilation system for the station and ventilation system for sectional area equipments were interchangeable. And the operation modes could be switched according to the different conditions to enhance the unilization ratio of the device and reduce the . first investment and maintenance cost of the device.
