Adjustment method for solving hydraulic imbalance problem of heat supply system

Abstract

The invention discloses an adjustment method for solving the hydraulic imbalance problem of a heat supply system. The method comprises the following steps of 1, numbering heat supply users, 2, collecting an outdoor temperature, 3, calculating parameters required for running adjustment, 4, determining the first heat supply users, 5, conducting running adjustment on the remaining heat supply users,and 6, repeating steps 2 to 5 to achieve the equivalent heat supply for the users. At intervals, user valves are switched on from the far-end users to the near-end users one by one, the power supply flow of a circulating water pump is adjusted while the switches are switched on, and it is ensured that the heat supply effects on the n users are consistent within an adjustment time period. Accordingto the method, the influence of the heat supply distance on the users is considered, the horizontal thermal imbalance of the heat supply system is fundamentally eliminated so that the near-end usersand the far-end users can all have the same heat supply effect, the adjustment characteristics of a pipe network are improved, the situation that the increase of the running energy consumption is caused by a large-flow running mode is avoided, and the pipe diameter of a main heat supply pipeline does not need to be increased.

Description

technical field [0001] The invention belongs to the field of heat supply adjustment and control, and in particular relates to an adjustment method for solving hydraulic imbalance of a heat supply system. Background technique [0002] User room temperature is related to many factors, such as outdoor air temperature, pipe network flow, heating water temperature, building heat consumption, etc. When the user's heat 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 heat supply regulation is to make the heat dissipation of the heating user's heat dissipation equipment adapt to the changing law of the user's heat load, so as to prevent the heating user from having a room temperature that is too high or too low. [0003] However, no matter what kind of heating adjustment method is adopted at present, it will happen that the nearby users first realize the heating adjustment...

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
