建筑热水管道系统是在环状管网条件下运行，其立管流量受环参数的影响，在原枝状管系条件下得到的设计流量值基础上重新分配。经分析发现，将热水的接入点和回水接出点分设在管系的两端，是最佳的管系图式。此时．最不利供水立管已不在系统的最远端．而是位于管系中部的立管．随着立管数量的增加，管系各立管配水流量的不均匀性也急剧增大，其相应的系统运行调试工作可参考本文中“热水立管局部阻力系数加载参考表”所提供的数据．将管系中部的主管作为基准来进行。
The construction hot water pipe system is operated under the condition of an annular pipe network, and the riser flow rate is affected by the ring parameter, and is redistributed on the basis of the design flow value obtained under the condition of the original branch pipe system. Through analysis, it has been found that the hot water access points and return water outlet points are located at both ends of the pipe system, which is the best piping system diagram. at this time. The most unfavorable water supply riser is no longer at the far end of the system. It is a riser located in the middle of the pipeline. With the increase in the number of riser pipes, the non-uniformity of the distribution flow of the riser pipes of the pipe system also increases sharply. For the corresponding system operation and commissioning work, reference can be made to the “Reference Table for Local Hot Water Pipe Upset Resistance Factor Reference” provided in this paper. data. Use the main pipe in the middle of the pipe as a benchmark.
