摘　　要：用水器具环状供水技术是保障用水终端水质的重要方式,欧盟发达国家应用普遍、技术成熟,在我国处于起步阶段,工程应用较少,针对计算流量不明确、管径选择原则不清晰等问题,以住宅、医院、食堂三类建筑为例展开精细化水力计算及管径选择分析,总结了不同类型建筑用水器具支管环状管道的计算流量确定方法及管径选择原则,为该项技术在实际工程应用提供理论支撑,为标准编制提供参考依据。Annular water supply technology with water appliances is an important way to ensure the end water quality.It is widely used and mature in developed countries of European Union.In our infancy,engineering applications are few,aiming at the unclear calculation flow and unclear principle of pipe diameter selection,taking residential,hospital and canteen buildings as examples,refined hydraulic calculation and pipe diameter selection analysis were carried out.This paper summarizes the calculation flow determination method and pipe diameter selection principle of different types of building water appliances branch pipe ring pipe,which provides theoretical support for the practical engineering application of this technology,and provides reference for the formulation of standards.
