区域能源系统在地铁车站的应用分析

Analysis on Application of District Energy System to Subway Station

本文主要以夏热冬冷地区某市地铁车站为例,分别从系统组成和经济分析两方面探讨了区域能源系统在地铁车站的应用特点。分析结果表明,区域能源系统可以取消地铁车站冷却塔及冷水机组等设备,减少地铁车站用地面积,缩减地铁车站冷水机房,节约车站初投资。但是,区域能源系统冷价较贵,运行费用高,综合经济优势不明显。

The characteristics of District Energy System(DES)applied in subway stations located in hot summer and cold winter region has been discussed for two aspects:system composition and economic analysis.It results that,the cooling tower and the refrigerator units can be canceled in the subway stations which applied the district energy system,the station occupied areas and the refrigeration room can be reduced,and the initial investment cost of the station can be saved.However,the cold price is too expensive,and operation costs is much higher,the comprehensive economic has no advantage.
