摘　　要：介绍了兰州某地铁站直接蒸发冷却设备的工程应用实例,通过对地铁站内直接蒸发冷却设备进、出口空气温湿度、送风量、机组耗水量的实际测试,分析出该蒸发冷却设备的蒸发冷却效率、机组制冷量。同时,还对机组蒸发冷却填料存在的干点问题和循环水泵运行能耗高等问题提出了后期的优化措施。通过分析表明,该直接蒸发冷却空调机组的出风效果良好,能满足该地铁站对冷量的需求,为后期直接蒸发冷却技术在轨道交通上的应用提供了现实的参考依据。This paper introduces the engineering application example of direct evaporative cooling equipment in a subway station in Lanzhou.Through the actual test of inlet and outlet air temperature and humidity,air supply volume and unit water consumption of the direct evaporative cooling equipment in the subway station,the evaporative cooling efficiency and cooling capacity of the unit are analyzed.At the same time,the dry point problem of evaporative cooling packing and high energy consumption of circulating water pump are put forward.The analysis shows that the air outlet effect of the direct evaporative cooling air conditioning unit is good,which can meet the demand of cooling capacity of the subway station,and provides a practical reference for the application of direct evaporative cooling technology in rail transit in the later stage.
