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。
The project overview of Shanghai Science and Technology City is introduced, and the composition and characteristics of ice storage system are introduced emphatically. The system adds a set of feed and return manifolds on the loop of ethylene glycol solution to make the low temperature ethylene glycol solution go its own way under the two conditions of ice storage and air conditioning without freezing phenomenon. This dual-manifold system is a two-stage pump system made of single-stage pump, solution pump also serves as ice storage pump, melting ice pump, simplifying the system, reducing the number of equipment, engine room area, power consumption and initial investment. The project has been run to meet the design requirements.
