【英文篇名】 Design of the ice storage system for Shanghai Science Land 【作者中文名】 陈怀琴; 叶祖典; 刘晓朝; 【作者英文名】 By Chen Huaiqin ★; Ye Zudian and Liu XiaochaoShanghai Institute of Architecture Design and Research; China; 【作者单位】 上海建筑设计研究院; 【文献出处】 暖通空调, Hv 双工况制冷机组; 双集管; 单级泵; 【英文关键词】 ice storage system; double duty chiller unit; double header; primary pump; 【摘要】 介绍了上海科技城的工程概况 ,着重介绍了蓄冰系统的组成、特点。该系统在乙二醇溶液环路上增加了一套供回液集管 ,使低温的乙二醇溶液在蓄冰和空调两种工况下各行其道 ,不产生冻结的现象。这种双集管式系统变二级泵制为单级泵制 ,溶液泵兼作蓄冰泵、融冰泵之用 ,简化了系统 ,减少了设备数量、机房面积、电耗和初投资。该工程已经运行 ,达到设计要求。 【英文摘要】 Presents the design of Shanghai Science Land project, especially the composition and characteristic of its ice storage system. Added in the system is a set of supply and return solution header on ethylene solution circuits, so that the solution goes through different pipes in the charging and discharging modes and there will be no freezing occurring in the pipeline. This dual header system changes the primary-secondary pumping system into a simple primary pumping system, in which the solution pumps work for...
