Simulation analysis of installation position of uniform pressure pipe in distributed variable frequency heating systems

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.
