Study on hydraulic balance regulation method of heating networks

 Hydraulic imbalance is the main reason for the high energy consumption of the heating system, and it is difficult to solve in practical engineering. In this paper, a hydraulic regulation model of the secondary heating network based on graph theory is established by using the proximity regulation method, and different regulation methods are evaluated and compared by using this model. The results show that the proximity regulation method starts from the worst hydraulic regulation degree users to adjust in the adjacent order, which has a good regulation effect and fewer regulation times, is conducive to accurate control, and can be used for the initial regulation of the secondary pipe network and the regulation of the operation process. The research results of this paper can provide guidance for on-site commissioning and control.
