旁通管定压供热系统允许最大建筑高度的确定
Discussion on allowable maximum building height for heating systems with bypass pipe pressurization
摘要：
提出了将旁通管定压系统应用于二次网供热系统中以解决供热区高层建筑和多层建筑的并网问题，给出了高低区合供时高层建筑最大允许高度的确定方法。该方法简单、工程实用性强，在缺乏管网资料进行换热站设计时，可以迅速确定供热小区允许的最大建筑高度。在后续管网设计过程中，通过水压图分析确定用户调节阀安装位置及节流量方可获得理想的并网效果。
Abstract：
Presents the application of bypass pipe pressurization to a secondary network system to solve the problems existed in heating network serving high-rise buildings and multi-storied buildings together, and provides the determining method of allowable maximum height of high-rise buildings. Simple and practicable, the method can be used to determine the allowable maximum building height quickly when designing heat exchange stations under shortage of pipe data. In following design process, desirable heating effect can be obtained through defining the location of household regulating valves and throttling quantity with pressure diagram.
