摘要
为协调冷却塔和地面条件的兼容,提出了将冷却塔布置在车站非设备集中端的方案,比较了冷水机房布置在车站设备集中端或非设备集中端2种方案的投资、能耗及对土建方案的影响。当冷却塔布置在车站非设备集中端风井地面附近时,冷水机房布置在设备集中端或非设备集中端2种方案均可实施,后者更节约投资和节能。工程中不宜硬搬执行GB 50157-2013《地铁设计规范》中"冷水机房应设置在靠近车站负荷中心的位置(设备集中端)"的要求,应根据实际工程条件,多专业综合分析,选择经济、节能的方案。
In order to coordinate the compatibility between the cooling tower and the ground conditions,proposes the scheme of placing the cooling tower at the non-centralized end of station equipment,and compares the investment,energy consumption and effect on civil construction of the two schemes of placing the chiller room at the centralized end or the non-centralized end of station equipment.When the cooling tower is arranged near the ground of air shaft at non-centralized end of station equipment,the chiller room can be arranged at the centralized end or the non-centralized end of the equipment,but the latter saves investment and energy.It is not suitable to simply carry out the requirement of"the chiller room should be located near the load center of the station(equipment centralized end)"in GB 50157—2013 Code for design of metro.The economic and energy-saving scheme should be selected according to the actual engineering conditions through comprehensive analysis of multiple majors.
