徐州地铁七里沟站蒸发冷凝系统应用分析

Analysis on Application of Evaporation Cooling System in Qiligou Station of Xuzhou Metro System

传统地铁的空调系统一般采用"水冷螺杆冷水机组+冷却塔"的组合形式,而冷却塔作为冷站的重要组成部分,存在耗水、耗电、占地面积大、协调难度大、噪声污染等诸多缺点。为较好地解决徐州地铁七里沟站冷却塔设置困难的问题,结合七里沟站的站型特点,采用蒸发冷凝空调系统,对蒸发冷凝系统的两种设置方案进行了分析,解决了冷却塔设置难度较大的问题。

The traditional subway air conditioning system generally adopts the combination form of "water-cooled screw chiller + cooling tower". As an important part of the cold station, the cooling tower has many disadvantages, such as water consumption, power consumption, large floor area, difficult coordination, noise pollution and so on. In order to solve the problem of difficult installation of cooling tower in Qiligou Station of Xuzhou Metro, combined with the station type characteristics of Qiligou Station, the evaporation and condensation air conditioning system was adopted in this station, and two installation schemes of the evaporation and condensation system were analyzed, which solved the problem of difficult installation of cooling tower in this station.
