The invention discloses a fixed-frequency pump type selection device of a ship central cooling system. The fixed-frequency pump type selection device of the ship central cooling system comprises a cooling water pump I, a cooling water pump II, a cooling water pump III, a control mechanism and a fresh water pipeline system, the control mechanism is in signal connection with the first heat exchanger, the first heat exchanger is arranged on the fresh water pipeline system, the water inlet end of the fresh water pipeline system is communicated with the seawater area through the second heat exchanger, and a second flow sensor and a temperature sensor are arranged on a pipeline between the fresh water pipeline system and the seawater area. A flow sensor is arranged on a pipeline between the fresh water pipeline system and the control mechanism, and a first cooling water pump, a second cooling water pump and a third cooling water pump are sequentially arranged on the fresh water pipeline system. According to the design, model selection can be carried out on the fixed-frequency pump according to the actual conditions of the seawater temperature and the flow, and the error of optimal low-temperature fresh water flow estimation is reduced.
