摘要：
上海宝山站采用双层车场的特殊结构形式,站房负荷的影响因素较复杂,运用eQUEST建立了负荷计算模型,对负荷的时间和空间分布特性进行了分析,并进一步分析了能源站采用蓄能式复合能源系统的技术经济适用性。结果表明:站房峰值冷、热负荷指标分别为212 W/m2和160 W/m2,全年负荷分布在负荷率50%～75%区间的最多,候车厅等公共区连通性较强,渗透风成为影响站房负荷的首要因素;蓄能式复合能源系统具有供能灵活且节能经济的特点,系统蓄冷率和蓄热率分别为17%和38%,与冷水机组+空气源热泵方案和冷水机组+燃气锅炉方案相比,其投资回收期分别为1.8年和3.2年,对于上海宝山站具有技术经济适用性。
Abstract：
Shanghai Baoshan Station adopts a special structural form of double-layer tracks, and the influencing factors of the station load are complex. A load calculation model is established using eQUEST, the temporal and spatial distribution characteristics of the load are analysed, and the technical and economic applicability of the energy station using an energy-storage composite energy system is discussed. The results show that the peak cooling and heating load indicators of the station are 212 W/m2and 160 W/m2, respectively. The load occurs mostly within the load rate range of 50% to 75% throughout the year. The connectivity of the waiting hall and other public areas is strong, and the outside air infiltration becomes the primary factor influencing the station load. The energy-storage composite energy system has the characteristics of flexible energy supply, energy saving and economic benefits. The cold storage rate and heat storage rate are 17% and 38%, respectively. Compared with the chiller plus air-source heat pump scheme and the chiller plus gas boiler scheme, the payback period is 1.8 years and 3.2 years, respectively, which is technically and economically applicable for Shanghai Baoshan Station.
