Description

Technical Field

[0001] The present invention relates to the technical field of thermal power industry, and specifically to an intelligent water supply thermal balance control optimization method. Background Art

[0002] The heat exchange station is a key component of the heating system, responsible for transferring heat energy from the heat source to the user end through the heat medium. Since the water temperature is in a constant state, when the user end needs to heat quickly, a heating device is usually installed at the user end to quickly increase the water temperature.

[0003] The existing technology lacks a dynamic pressure control mechanism when using a heating device for rapid heating. When the water temperature rises, the gas dissolved in the water will be released to form bubbles, resulting in an increase in local pressure, which affects the stability of the heating system. If a pressure regulating valve is set, the construction cost of the pipeline will be increased. In addition, the existing heating water pressure cannot be adjusted according to the temperature, resulting in uneven pressure on the pipeline and reducing the life of the pipeline. Therefore, it is necessary to design an intelligent water supply hydraulic balance control optimization method that effectively balances the pressure. Summary of the invention
