摘　　要：以散热器垂直单管供暖系统工程为例,在分析基本原理的基础上,建立以总年费为目标的数学模型,分析了不同热媒温度对经济比摩阻的影响,并给出了低温热媒下经济比摩阻的取值范围,而且对影响系统经济比摩阻的敏感性因素进行了分析,得出了有价值的结论。In this paper, taking the work of vertical one-pipe heating system of radiators as an example, based on the analysis of basic principle, set up a mathematical model based on the total annual fee. Analyses different temperature affecting the economical frictional resistance, and give the design value range of the economic specific frictional resistance, and analyses some sensitive factors affecting the economic specific frictional resistance, it draws some valuable conclusions.
