摘 要

上海地铁龙阳湖车站，是地下站台，现对其进行通风空调设计。

对于地下地铁车站，与地上建筑的空调设计有所区别，只负责夏季的制冷空调设计，冬季则排除在外。城市地铁车站客流的特点即为晚高峰是一天中最大流量时段，根据晚高峰时段的客流，人的冷湿负荷指标，设备数量和冷湿负荷指标，可得站厅、站台冷湿负荷，同理可得设备与管理用房的冷湿负荷。针对公共区与设备与管理用房区的特点，将车站空调区划分成2个大系统，5个小系统。2个大系统分别负责站厅和站台的空调要求，5个小系统则分别负责不同类型的设备与管理用房的空调要求。

制冷机组采用地铁车站常用的水冷式压缩冷水机组，并用冷却塔制得冷却水。因同程式的布置方式较为节能，压力平衡也较容易，则水系统采用同程式水管系统。

因地铁车站的位置特点，空间较为有限，不宜另外布置排烟管道，则采用通风空调系统的排风管作为排烟管共用管道,选用排烟排风两用的双速风机。

最后，提出一些改善措施。

The Air-conditioning Design Of Longyanghu Underground Station In Shanghai

ABSTRACT

Longyanghu underground station in Shanghai is setted under ground.A design is going to be made to solve its ventilating and air coditioning problems.

The air-conditioning design of underground station under ground is different from buildings on the ground.It includes cooling system in summer without heating system in wintter.The characteristic of city underground station’s passenger flow is that it’s intensive during evening rush hour.According to the passenger folw,the index of people’s cooling load and moisture load, the index of facility’s cooling load and moisture load, the cooling and moisture load of the subway hall and the platform will be caculated.Similarly, the cooling and moisture load of facility and management rooms will be get.To solve the problem,the air-conditiong field will be divided into 7 systems,including 2 large system and 5 little systems.2 large systems are charge for the subway hall and the platform,while 5 little systems are charge for the facility and management rooms.

The refrigerating machine sets adopted are water-cooled chillers.They get cooling water from cooling towers.Since reverse return water system reduces consumption of energy and is easier to balance the resistance,the reverse return water system is adopted.

Since the space of the underground station is not plenty,it’s difficult to set more air duct to exhaust smoke.So,the smoke duct and exhausting air duct are the same one.Choose a double speed fan to finish the work.

Finally,some measures are put forword to improve the design.

Keywords:Underground station Ventilation and air condition Cooling and moisture load Large system Little system Reverse return system exhaust smoke
