摘　　要：本文分析了新双管系统与传统双管系统的不同,提出了确定新双管系统平均比摩阻取值的方法,并通过水力计算,确定并验证了新双管系统中,立管与水平支路的平均比摩阻的取值,为新双管系统水力设计计算提供参考。Analyzes the difference between new two-pipe heating system and traditional one. puts forword the wayof determining mean friction resistance of the new two-pipe heating system. Through hydraulic calculation,determines and tests mean friction resistance of riser and horizontal branch circuit of the new two-pipeheating system, provides reference for its hydraulic design calculation.
