To provide a low cost central cooling water system with a simple configuration in a cooling water system for a ship.
A cooling water system includes: one or more cooling water pumps 2, 3, 4; a cooled apparatus, such as a main air cooler 11, to be cooled by cooling water from the cooling water pumps; a temperature adjustment valve 15 which is provided at the outlet piping of the cooled apparatus and adjusts the flow rate of the cooling water flowing in the apparatus in accordance with the temperatures of the apparatus, or an automatic stop valve 16 which adjusts the flow rate of the cooling water flowing in the apparatus in accordance with the viscosity of the lubricating oil of the apparatus; and a pressure transmitter 7 which measures the pressure of the cooling water flowing in the piping arranged on the outlet piping side of the cooling water pumps. The output of the cooling water pumps can be controlled on the basis of the pressure value detected by the pressure transmitter.
