某地铁枢纽站冷源方案的选择分析与探讨

Analysis and discussion on the selection of cold source scheme for a metro hub station

结合某地铁枢纽站冷源系统,介绍了螺杆式水冷冷水机组、整体式蒸发冷凝机组、分散式蒸发冷凝机组、机场能源中心供冷4种方案,并进行了经济技术比较,通过价值系数法分析选取能源中心供冷方案作为推荐方案,并在方案比选的过程中得出蒸发冷凝空调系统不仅可以多样化地解决地铁中的问题,同时在保护环境、节约能耗以及投资成本等方面都具备显著的优势。

Combined with the cold source system of a metro hub station,four schemes of screw water cooling chiller,integral evaporative condensing unit,dispersed evaporating condensing unit and airport energy center cooling are introduced,and economic and technical comparison is made.The energy center cooling scheme is selected as the recommended scheme by value coefficient method.And in the process of scheme comparison,it is concluded that the evaporation and condensation air conditioning system can not only solve the problems in the metro diversifiedly,but also has obvious advantages in environmental protection,investment cost and energy saving,etc..
