Abstract

The invention discloses a flow regulating method and system for improving hydraulic imbalance of a secondary heating network. The secondary heating network comprises a plurality of water inlet branches and user end heat supply pipelines, and each water inlet branch communicates with the multiple user end heat supply pipelines; and each water inlet branch communicates with an intelligent flow balance valve, and each user end heat supply pipeline communicates with a static flow balance valve. The flow regulating method comprises the steps of measuring an inlet and return water pressure difference value of each water inlet branch; measuring a valve flow value of each water inlet branch; calculating an actual pipeline resistance value of the water inlet branch where each intelligent flow balance valve is located by using the water inlet and return pressure difference value and the valve flow value; calculating a target valve opening of each intelligent flow balance valve by using the actual pipeline resistance value; and adjusting the actual valve opening of the intelligent flow balance valve to the target valve opening. The technical scheme of the method and system aims to solve the problems of energy waste and low energy efficiency of a heat supply mode and influence on user experience in the prior art.

Description

technical field [0001] The invention relates to the technical field of central heating, in particular to a flow regulating method and system for improving hydraulic imbalance of a secondary heating network. Background technique [0002] The central heating system is a system in which steam or hot water generated by a centralized heat source is supplied to a city or a part of the area through a pipe network to produce, heat and live in heat. The central heating system mainly includes heat source plant, primary heating network, heat exchanger and secondary heating network; among them, the secondary heating network directly supplies heat to users. [0003] In the secondary heating network part of the central heating system, there are often some cases where the room temperature of some users does not meet the standard due to the user flow not reaching the design flow value between the heat users and the cooling equipment. Failure to meet the standard is commonly referred to as ...
