摘　　要：从改变管网动力分布的角度提出3种区域空调冷水二级泵系统,利用动态经济分析方法,建立了基于目标时间的净现值的二级泵系统经济性分析模型,并以实际的区域供冷工程为例计算分析了不同动力分布系统的初投资和运行费用(能耗),得出集中式二级泵系统的净现值最低、经济性最好。而分布式二级泵系统的运行费用最低、节能性最好。In this paper,three kinds of secondary pump styles have been proposed for the District-Cooling systems.Using the dynamic economic analysis method,an efficiency analysis mathematic model is build based on the present value of target time for the secondary pump system.Then the initial investments and operation costs calculation for the three secondary pump styles of a real project in Shanghai is taken as an example,and it is concluded that the net present value of the centralized pump system is the lowest,its efficiency is the best.The distributed secondarily pump system has the lowest operating cost and the best energy saving.
