摘　　要：本文建立了一种同程式热水供暖系统动态水力特性分析的数学模型,并对采用传统水力计算方法(即经济比摩阻法)设计的管路系统进行了模拟分析,对比了在流量、阻力等方面由于计算方法引起的静态设计与动态计算的实际差别,剖析了当前设计阶段水力计算方法存在的问题。结合国内外建筑节能的发展趋势,有针对性地提出了热水供暖系统设计的优化建议。A mathematical model for the dynamic hydraulic characteristics analysis on the reverse return hot water heating system was established in the paper, and the pipeline system designed by the traditional hydraulic calculation method(namely optimal specific frictional head loss) was simulated and analyzed in detail. Then the actual differences between static design and dynamic calculation due to the influence of the hydraulic calculation method were compared, and the problems of the hydraulic calculation method in the current design stage was analyzed. Finally, according to the development trend of building energy efficiency at home and abroad, the optimization suggestions of hot water heating system design were proposed.
