摘要
地铁运营能耗中通风空调系统的能耗占总能耗的30%-40%。地铁车站四周土壤资源丰富,为地道风系统的利用提供了良好的条件。针对这一特点对地铁站台地道风系统建立模型,运用FLUENT模拟夏季典型最热天地道出风温度变化规律、计算分析地道风系统的换热效果和冷却效率。结果表明,经地道处理过后新风温度满足地铁车站通风温度标准,其在地铁车站中的应用具有节能性。
Energy consumption of ventilation and air conditioning system in subway operating energy consumption accounts for 30% -40% of total energy consumption. The soil around the subway station is rich, which provides good conditions for the use of the tunnel air system. This paper establish a model of metro station tunnel air system and use FLUENT simulation analysis underground air temperature of short-term conditions in the most typical summer hot weather, calculation and analysis of tunnel ventilation system of the heat exchange efficiency and cooling efficiency. The results show that the air temperature in the subway station is satisfied with the standard of air temperature, and the energy saving of the subway station is confirmed.
