| 摘 要： | 采用依次关闭各支路，然后计算未关闭支路流量的方法，分析和对比异程系统与同程系统的稳定性。结果表明，异程系统从离热源最近的支路到最远支路，稳定性依次变差；同程系统的稳定性具有对称性，网路中部的支路稳定性最差，越往两端，支路的稳定性越好；从总体上讲，同程系统的稳定性差于异程系统。

| Abstract: | By employing the method that shuts each subcircuit,the paper analyzes and compares the hydraulic stability of direct return system(DRS) and reverse return system(RRS).The results show that: from the subcircuit that is furthest to the heat source to the nearest one,the stability of DRS becomes gradually worse;the stability of RRS is symmetrical,with the subcircuit in the middle of the pipe-network having the worst stability,while,the nearer to the two ends,the better the stability of the subcircuits is.It's concluded that the overall stability of RRS is inferior to DRS. |
