摘　　要：为给筹备中的大型科技馆提供关于冰蓄冷系统投资、建设和运行方面参考,结合实例分析了我国具有代表性的大型科技馆冰蓄冷系统运行数据。从初投资、全年耗电量、移峰值和电费成本四个方面对比常规冷源系统作出经济分析。通过对比分析得出初投资增加162万元、耗电量增加8.38%、移峰值占比71.37%、节约电费成本水平保持在30%左右。并做出投资回收期和固定资产折旧分析,计算得出静态投资回收期约为5年、动态投资回收期约为7年、冷水机组有效寿命期末残值为15.2万元。In order to provide a reference for the investment, construction and operation of ice-storage system in the large science and technology museums under preparation. This paper analyzes representative ice-storage system in large science and technology museums in China with examples.Compared with conventional cold source system, this paper makes an economic analysis from four aspects about initial investment,power consumption,peak cutting value and electricity cost. Through contrastive analysis,the initial investment increased by 1.62 million yuan, the power consumption increases by 8.38 %, the peak cutting value rate is 71.37 %, and the electricity cost saving level is maintained at about 30 %. The investment payback period and the depreciation of fixed assets are analysed. It is concluded that the static payback period is about 5 years,the dynamic payback period is about 7 years, the final residual value of the effective life about the water chillers is 0.152 million yuan.
