摘要：以不同通风空调系统形式的南京地铁3、4号线“L型”换乘车站市政府站(南京3号线大表冷集成闭式系统，南京4号线站台门系统)为例，详细分析地面冷却塔、下沉式冷却塔、集中冷站(与南京3号线新庄站合设)以及蒸发式冷凝机组4种冷源方案，并对其进行技术、经济比较，认为常规制冷+地面冷却塔方案的工程初投资和
点及总设备投入少，其年折算费用最低，但国内实际使用案例较少。集中冷站方案工程初投资居中，但其年折算费用最高。下沉式冷却塔方案，工程初投资较地面冷却塔高，但年折算费用适中，并能够有效解决城市景观、周
边住户噪声及健康、“漂水”、“散热”等问题，在景观要求比较高的地区可优先采用。关键词：地铁换乘车站：大表冷集成闭式系统：站台门系统：冷源方式

Abstract: The conventional cold source (floor mounted cooling tower of subway station) inherently has some disadvantages such as noise, splash, environment pollution, and cityscape influence, particularly in crowded downtown areas. In this paper, four schemes, i.e. floor mounted cooling tower, sunk cooling tower, central refrigeration station (associated with Xinzhuang Station of Line 3 of Nanjing Metro), and evaporative chillers, are comprehensively discussed, with the example of Shizhengfu transfer subway station in Nanjing city, which has different HVAC systems and transfers between Line 3 (surface air cooler HVAC system) and Line 4 (platform screen door HVAC system) of Nanjing. After careful technical and economic analysis, it is indicated that the engineering primary costs and annual convert costs are both minimum with the floor mounted cooling tower scheme, but its neighboring influence is maximum caused by the cooling tower; the engineering primary costs of
evaporative chillers scheme are the highest, but its annual
t costs are the lowest because of the high-efficiency,
energy-saving, and small equipment operation; the annual convert costs of a central refrigeration station scheme are the highest even though its engineering primary costs are medium; the sunk cooling tower scheme can be adopted preferentially because its annual convert costs are almost the same as those of the floor mounted cooling tower scheme, and all the inherently existing problems can be solved effectively at the same time.
