重庆地铁站通风空调系统节能改造
Energy saving transformation of ventilation and air conditioning system of an underground railway station in Chongqing
摘要：
分析了重庆地铁1号线某地下车站通风空调系统的运行数据及其夏季工况的室外气象参数，结果表明其运行能耗偏高，存在较大节能潜力。经综合分析，确定采用调整车站公共区温度，变频控制相应的风系统和水系统优化措施。TRNSYS软件对比模拟结果表明，改造后通风空调系统整体运行能耗降低18.3%，相应投资回收期不到3 a，在重庆地铁站改造中具有良好的应用前景。
Abstract：
Analyses the operating data of the ventilation and air conditioning system of the underground railway station and the outdoor meteorological parameters under summer operating conditions. The result shows that the energy consumption is high, with a great energy saving potential. After the comprehensive analysis, adopts the optimization measures including adjusting the set temperature of the station public area, and controlling air system and water system by frequency conversion. Simulation result of the TRNSYS software shows that the energy consumption of ventilation and air conditioning system reduces 18.3% after the energy saving transformation, and the corresponding investment payback period is less than 3 years. It has a good application prospect in the transformation of underground railway stations in Chongqing.
