地铁车站空调系统冷却塔设置方式对地面环境影响分析

Analysis on Influence of Arrangement Mode of Cooling Towers of Air-conditioning System of Metro Stations on Ground Surface Environment

随着城市地铁工程的建设以及沿线部分车站与周边用地条件的限制,冷却塔的布置与城市景观不协调的现象及对周边居民的影响日渐凸显。介绍分析4种冷却塔布置形式(地面冷却塔、下沉式冷却塔、地下封闭式冷却塔和蒸发式冷水机组),从对周边环境的影响、技术特点、工程初投资情况及运营费用等方面对比分析这几种冷却塔布置形式。认为,地铁车站应结合环境评价及建设条件进行综合对比,并选取对应的辅助措施。

The conflict between the arrangement of the cooling towers of the air-conditioning system of Metro stations and the surrounding environment becomes more and more serious. In the paper, 4 types of cooling tower arrangement modes, i. e. , ground surface cooling towers, sunk cooling towers, closed underground cooling towers and evaporative chillers, are presented. Comparison and contrast are made among the fore-mentioned 4 types of cooling tower arrangement modes in terms of influence on the surrounding environment, technical features, initial investment and operation cost. It is pro- posed that proper arrangement of cooling towers should be made on basis of the environment assessment results and the specific project conditions.
