得到了单管多热源联网供热系统经济性最好的结果,说明单管多热源联网供热系统在经济上是可行的
） 摘要： 单管多热源联网供热系统是在两个及两个以上热源联合运行的情况下、热媒经第一热源升温后
顺序流过热用户、第二热源、热用户等后返回第一个热源、沿途管网由单管组成、其既是供水管也是回水管一种新型的供热系统
采用寿命周期成本及净现值率的方法
并考虑了当热用户相对热源位置变化时对供热系统经济性的影响
通过与传统的单热源双管枝状管网供热系统和多热源双管环状管网供热系统对比分析
） Abstract： Single-pipe heating system networked with multiple heat sources is a new heating system that heat medium, after heated by the first heat source, orderly flows through heat users、 the second heat source and other heat users, etc, then goes back to the first heat source
The network is composed by single pipe which is not only supply pipe but also return pipe
Taking a project in Taiyuan as an example, by using life cycle cost and net present value ratio, the paper carries out comparative analysis of the economy of single-pipe heating systems networked with multiple heat sources、double-pipe branching heating system with single heat source and double-pipe loop network heating system with multiple heat sources, in accord with the influence on the economy of heating system when the relative place of heat users changing, then gets the result that the economy of multiple- heat- source networking heating system with single pipe is the best, which indicates that single-pipe heating systems networked with multiple heat sources is economically feasible
