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“最优比摩阻”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.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.

关 键 词：优化设计 均匀性 比摩阻 经济性 可靠性
