摘要
以成都市某屏蔽门地铁车站为例,结合客流量及地铁车站用电量等实测调研数据,建立车站能耗模型,分项分析了该地铁车站的空调负荷特征,提出相应的节能策略。结果表明,人员和机械新风是地铁车站空调负荷最主要的来源,2项负荷占总负荷的比例可达55%;出入口渗风负荷占比也高达18%,与机械新风相近。通过预测客流量变化,实现前馈与反馈相结合的机械新风调控策略和渗风利用策略是减少地铁车站通风空调能耗的重要途径。
Taking a screen door metro station in Chengdu as an example,combined with the passenger flow and metro station electricity consumption and other measured research data,establish the station energy consumption model,the air conditioning load characteristics of the metro station are analysed,and corresponding energy-saving strategies are proposed.The results show that personnel and mechanical fresh air are the most important sources of air-conditioning loads in metro stations,and the ratio of the two loads to the total load can reach 55%;the ratio of seepage air loads at entrances and exits is also as high as 18%,which is similar to that of the mechanical fresh air,therefore,by predicting the changes in the flow of passengers,the combination of feed-forward and feedback mechanical fresh air control strategy and seepage air utilisation strategy is an important way of reducing the energy consumption of ventilation and air-conditioning in metro stations.
