热水供热管网最佳经济比摩阻研究与分析

摘要

The mathematical model of economic specific frictional resistance was established by using the minimum annual cost of heating pipe as the optimization objective and the calcu -lation method of the economic specific frictional resistance , the economic pipe diameter and the economic flow rate were obtained .The typical heat scale economic specific frictional re -sistance and various kinds of factors of economic specific frictional resistance were calculat -ed.The results showed that the economic specific frictional resistance was inversely propor -tional to the scale of the heat scale , and the actual economic specific frictional resistance was different with the traditional range recommended .%以供热管网的费用年值最小为优化目标建立了经济比摩阻数学模型，通过优化得到了经济比摩阻、经济管径及经济流速的计算方法。计算了典型供热规模的经济比摩阻及各种因素对经济比摩阻的影响，经济比摩阻与供热规模成反比，实际的经济比摩阻与传统的推荐范围不同。
