地铁通风空调系统节能分析

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。

Analysis of saving energy for metro ventilation and air conditioning system

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 mathematical models of the metro ventilation and air conditioning system were established. The energy consumption 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 operating 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.
