Simulation analysis of installation position of uniform pressure pipe in distributed variable frequency heating systems
摘要：
针对以均压管定零压差点运行调节的分布式变频供热系统，利用一维流体仿真软件Flowmaster，结合实际工程，对均压管安装在热源和第一热用户处2种位置的系统水压图和变流量调节水力特性进行了对比分析。结果表明：均压管安装在第一热用户处可以在一定程度上缓解后端换热站超压的问题，变流量调节中可提高分布式换热站的水力稳定性。
Abstract：
For the distributed variable frequency heating system using the uniform pressure pipe to adjust zero pressure difference point, combining with the one-dimensional fluid simulation software Flowmaster and practical engineering, simulates and analyses the system water pressure diagram and variable flow regulating hydraulic characteristics under two conditions of the uniform pressure pipe installed at the heat source and the first heat user. The results show that the uniform pressure pipe installed at the first heat user can alleviate the problem of back-end heat exchanger overpressure and improve the hydraulic stability of distributed heat exchanger station in variable flow regulation.
Keywords:distributed variable frequency system, heating uniform pressure pipe, zero pressure difference point, heat source, the first heat user
