【摘要】 本文分析了重力作用压头对低温热水计量采暖系统共用立管形式的影响,通过运用基尔霍夫定律分析了下分异程式双管系统和下分同程式双管系统的水力平衡状况,得出了下分异程式双管系统更适用于低温热水采暖系统的结论,并确定了立管经济比摩阻的范围和下分异程式双管可以负担的楼层数。更多还原

【Abstract】 This paper analyzes the effect of gravity head on different forms of low temperature hot water heating system common riser, by using Kirchhoff s law analyzes downfeed and upfeed two-pipe system s hydraulic balance status. The conclusion is that upfeed two-pipe system is somewhat more suitable for low temperature hot water floor radiant heating system, establish the range of average friction resistance of the common riser and the number of floors the common riser can burden.更多还原
