| 摘 要： | 对区域供热供冷水管网系统管径参数选择的“均匀性”设计方法,从技术角度进行经济性分析,探求管网设计的内在规律,结果表明：与传统的“最化比摩阻”设计相比,只要相应地调整初投资比例,就可以在保持初投资不变的情况下节省大量的运行费用．

| 关 键 词： | 优化设计 均匀性 比摩阻 经济性 可靠性 |

| Abstract: | Having put forward the systematic " homogeneity " design philosophy that chooses pipe diameter parameter to regional heating cooling,and having done economy analysis from the technological angle,we seek pipe network design inherent method,compared with traditional " optimum frictional resistance per meter " design,so long as we adjust the ratio of initial investment accordingly,we can save a large sum of operation expenses and keep the initial investment unchanged. |

| Keywords: | optimum design homogeneity frictional resistance per meter economy dependability |
