Variable working condition low noise configuration regulation and control method for ship cooling pipeline system

The invention relates to a variable working condition low noise configuration regulation and control method for a ship cooling pipeline system, and the method comprises the following steps of establishing a comprehensive characteristic database of system device; judging the flow of cooling fluid required in a cooling pipeline system under the current operation condition according to the system operation parameters, and realizing the heat exchange balance of the system; establishing a one-dimensional model of the pipeline system, and performing hydraulic power matching calculation on the whole cooling pipeline system to obtain a plurality of device combination operation schemes to realize hydraulic power balance of the system; and according to the noise source characteristics of each device in the database, calculating the noise value transmitted to the pipeline which is communicated with the sea mouth, evaluating the acoustic levels of different schemes, and then determining the optimal low-noise configuratio
