针对集中供热系统管网设计中存在的技术、节能、经济等特点，提出了一种新型供热系统管网优化设计新模式，即以水力计算为依据，选择优化管径布置模式，在此基础上，利用全寿命周期内管网成本最低原则，确定最佳的集中供热系统优化方案。实例演算表明，此种集中供热系统管网优化设计模式，既可以保证供热系统管网技术性能最优，也可以最大限度降低供热管网的初投资以及运行总费用。

This paper used pipe network of central heating system as the research object, and proposed a new type of pipe network optimization design for the central heating system. The diameter arrangement is first determined based on hydraulic calculation, and then the optimal design of central heating system is identified based on the whole life cycle. Examples of calculations have proved that this method could ensure that pipe network of central heating system has the excellent technical performance, but also can greatly reduce the total cost of the initial investment and the heating pipe network operation.
