摘要
通过分析铁路站房、西北地区气候以及蒸发冷却空调技术的特点,提出了将蒸发冷却空调应用于西北地区铁路站房的理念。在此基础上提出了两种蒸发冷却空调方案,即蒸发冷却全空气系统和基于蒸发冷却的辐射供冷+置换通风半集中式蒸发冷却空调系统。并对其可行性进行了理论分析。结果表明,蒸发冷却空调这一节能、环保的空调方式完全可以满足铁路站房舒适性要求。既可以有效改善室内空气品质,又可以大大节约站房空调的能耗和运行费用,是一种值得推广的铁路站房空调方式。
Through the analysis of characteristics on the railway stations,the climate of the Northwest area,and the evaporative cooling air-conditioning technology,an new idea that apply the evaporative cooling air-conditioning system in the Northwest railway stations was put forward.Based on this,two kinds of evaporative cooling air-conditioning scheme has been proposed,namely all-air evaporative cooling air conditioning systems and the hybrid air conditioning system of floor radiant cooling with evaporative cooling and displacement ventilation.Meanwhile we conduct on its feasibility.The result shows that the evaporative cooling air conditioning systems with energy-saving and environmentally friendly can fully meet the comfort requirements of railway stations.On the one hand it can improve the indoor air quality effectively,on the other hand,it can reduce the energy consumption and the operation cost in railway station.It's worthy popularizing in railway station.
