摘　　要：建立一种建筑给排水PPR管道延迟冻结保温层计算模型,提出PPR管道延迟冻结保温层厚度计算的方法,分析比较了该方法与《工业设备及管道绝热工程设计规范》、《设备及管道绝热设计导则》进行建筑给排水管道延迟冻结保温层厚度计算的结果,给出常用PPR管道延迟冻结保温层厚度的减少率与保温材料节省量为建筑给排水管道延迟冻结保温层厚度设计计算提供参考与借鉴。Established a building water supply and drainage PPR pipe insulation layer of delay freeze calculation model. Proposed calculation method for PPR pipes delay freezing of insulation thickness. Analysis and compared the results of this method and Code for design of industrial equipment and pipeline insulation engineering,and Guide for design of thermal insulation of equipments and pipes is for building water supply and drainage pipe delay freeze insulation layer thickness calculation,to given the reduced rate of common PPR pipeline delay freeze insulation layer thickness of and the save volume of insulation material. In order to provides reference for the design calculation of building water supply and drainage delay freeze insulation layer thickness.
