地铁通风空调系统节能分析

Analysis of saving energy for metro ventilation and air-conditioning system

为减少地铁通风空调系统能耗,合理利用地铁活塞风,在对国内外地铁通风空调系统节能现状分析的基础上,对南京地铁1号线地铁通风空调系统能耗影响因素进行分析,建立了地铁通风空调的物理和数学模型,运用地铁热湿负荷分析模拟软件(STESS),得出了各种运营模式下地铁通风空调能耗曲线,确定了地铁通风空调系统优化运营模式。近2年的实际运行表明,通风空调系统节能达20%,与理论分析模拟相吻合。

To reduce the energy consumption of metro ventilation and air-conditioning system, and to ensure the rational use of the underground air piston, based on the analysis of the status of the saving energy in metro ventilation and air-conditioning system at home and abroad, the factors on Nanjing Metro 1 Line metro ventilation and air-conditioning system energy consumption were analyzed. The physical and mathe- matical models of the metro ventilation and air-conditioning system were established. The energy consump- tion curve of the metro ventilation and air-conditioning system in a variety of operating modes was obtained by the simulation software （subway thermal environment simulation software,STESS）, and the metro op- erating mode was optimized. The actual metro ventilation and air-conditioning system energy consumption in the past two years saved up to 20%, consistent with the theoretical analysis and simulation.
