A Control System to Solve Hydraulic Imbalance of Heating System

Abstract

The invention discloses a control system for solving hydraulic imbalance of a heat supplying system. The control system comprises a heat supplying pipe network for supplying heat to users. A valve isarranged in the heat supplying pipe network and controlled by a valve manager. The valve manager is connected with a parameter calculator, the parameter calculator is connected with a numbering device, and the numbering device conducts sequence numbering. The parameter calculator is further connected with an outdoor temperature collector, and the outdoor temperature collector collects the outdoortemperature. The heat supplying pipe network comprises a heat supplying main pipeline, and the heat supplying main pipeline communicates with a user heat supplying branch where the users are located.According to the control system for solving the hydraulic imbalance of the heat supplying system, the influence of the heat supplying distance on the users is considered, the horizontal thermal imbalance of the heat supplying system is eliminated fundamentally, thus the same heat supplying effect can be achieved on the users at the near end and the far end, the adjusting characteristic of the pipenetwork is further improved, increasing of operation energy consumption due to the large-flow operation mode is avoided, and the pipe diameter of the heat supplying main pipeline does not need to beincreased either.

Description

Technical field [0001] The invention belongs to the field of heating regulation control, and in particular relates to a control system for solving the hydraulic imbalance of the heating system. Background technique [0002] The user's room temperature is related to many factors, such as outdoor temperature, pipe network flow, heating and water supply temperature, and building heat consumption. When the user's thermal load changes, in order to achieve on-demand heating, it is necessary to adjust the flow rate and water supply temperature of the heating system. The purpose of heating regulation is to adapt the heat dissipation of the heat dissipating equipment of the heating user to the changing law of the user's heat load, so as to prevent the heating user from experiencing excessively high or low room temperature. [0003] However, no matter which heating regulation method is adopted at present, it will happen that the nearby users realize the heating regulation first, and the rem...

AI Technical Summary

Problems solved by technology

The large flow operation mode does not fundamentally eliminate the horizontal thermal imbalance of the heating system, but instead increases the flow of the water pump, resulting in an increase in operating energy consumption and deterioration of the regulation performance of the heating system

In addition, increasing the circulation flow also requires increasing the pipe diameter of the main heating network
