摘　　要：分析讨论了生活热水系统中用水点热水出水时间的规范强制性规定及热水出水时间的影响因素,提出了以非恒温热水支管的容积和热水出水时间为基础的双控措施,控制非恒温热水支管的容积以达到节水目的,控制热水出水时间以进一步提高用水的舒适度。给出了几种常用管材规格的计算指标,并换算为节水设计长度以方便工程设计应用。Through analyzing the compulsory index of hot water outflow delay by non-constant temperature hot water branch in hot water supply systems and how relative parameters influencing on values of the index,a method was presented that tow controlling indexes should be used simultaneously:the index of volume of non-constant temperature hot water branch for purpose of water saving,and the index of hot water outflow delay further to improve people's feeling using hot water.Water saving design length of some frequently-used pipes was proposed according to this tow indexes to make calculating more convenient.
