集中供热管网比摩阻的简易计算方法探讨

Discussion on a simplified calculating method for specific frictional resistance of central heating network

介绍一种利用比摩阻与管段阻力特性系数及流量平方成正比的关系,快速、准确计算供热管网比摩阻的方法。该计算方法通过与水力计算软件结果进行对比,找出了软件计算中产生误差的原因。

This paper introduces a relationship that specific frictional resistance is in direct proportion to pipeline resistance characteristic coefficient and flow squared,by which the specific frictional resistance of heating network could be calculated in a fast and accurate way.Through comparing with the result of hydraulic calculation software,the reason of errors in software calculation is found out.
