北京电力总医院电蓄能供热系统的工程改造

Project transformation of the electric power heat-storagesystem in Beijing Electric Power General Hospital

北京电力总医院原电蓄能供暖系统存在热用户的用热量及时间未分类、水箱内流场及温度场分布不均等诸多问题。针对具体问题提出了改进措施,包括对流场、温度场的重新设计,大幅度减少水箱蒸发面,水箱保温采用木块固定外保护层的方法。对工程改造进行了技术及经济性分析,采暖期3个月,节约电费175.34万元,投资回收期约4.5个月。

The electric power heat-storage system in Beijing Electric Power General Hospital Hospital exists many problems.Against the specific problems,this paper puts forward corresponding improvement measures including design of the convection field and temperature field.significantly the reduction of water tank evaporation surface,heat preservation of water lank by using block to fix outside protective layer.By analyzing the technology and economy of project transformation ,we can get that we save 1.7534 million yuan tariff during three-mooth heating periods,and the investment recovery poriod is about 4.5 months.
