某地铁车站中蒸发冷凝式冷水机组的应用分析

Applied analysis of evaporative condensing water chiller of underground metro station

目前,地铁地下车站的空调冷源系统通常采用水冷冷水机组+冷却塔的组合方式。在实际工程中,冷却塔在室外地面的安装位置存在用地困难、景观难以协调以及运行噪声投诉等问题。结合重庆某地铁车站的实际案例,分析具体存在的问题,采用整体蒸发冷凝式冷水机组替代传统的水冷冷水机组和冷却塔,较好地解决车站空调冷源的问题,并从占地面积、投资费用、节能、节水方面进行了方案比较,分析了蒸发冷凝式冷水机组在地铁工程中应用的适用性。

At present,the cooling source system of air conditioning in underground metro station mostly adopts water-cooling chiller and cooling tower.In practice,it is difficult to choose the position of cooling tower,coordinate the landscape and solve the noise problem.Taking an underground metro station as an example,which adopts evaporative condensing chiller to replace traditional chiller and cooling tower system,introducing specific problems and solutions in this paper.The applicability of evaporative condensing chiller in underground metro station is discussed,by comparing land using,investment estimation,energy saving and water saving.
