The invention relates to the field of ship equipment cooling, and discloses a ship cooling water control system and a ship cooling water control method. Seawater output by a seawater cooling unit and fresh water output by a fresh water cooling unit are subjected to heat exchange in a central cooler; the central cooler is connected with a second input end of the three-way temperature control valve so as to input the fresh water subjected to heat exchange into the three-way temperature control valve, and the three-way temperature control valve is connected with the equipment unit; a first frequency converter is arranged between the control unit and the seawater cooling unit; a second frequency converter is arranged between the control unit and the fresh water cooling unit; the control unit is also electrically connected with a third temperature sensor; when the cooling water system needs to be controlled, the three-way temperature control valve, the seawater cooling unit and the fresh water cooling unit are jointly controlled through the control unit, and the running power of the seawater cooling unit and the running power of the fresh water cooling unit are adjusted and controlled more intelligently by introducing the external real-time seawater temperature, the cooling water demand quantity and the working load. The cooling requirement of the equipment unit is met, and meanwhile the energy-saving effect is achieved.
本发明涉及船舶设备冷却领域,公开了一种船舶冷却水控制系统及控制方法,其海水冷却单元输出的海水与淡水冷却单元输出的淡水在中央冷却器中进行热交换;中央冷却器与三通温控阀的第二输入端连接以将换热后的淡水输入三通温控阀,三通温控阀连接设备单元;控制单元与海水冷却单元之间设有第一变频器;控制单元与淡水冷却单元之间设有第二变频器;控制单元还电连接有用于第三温度传感器;在需要对冷却水系统控制的时候,通过控制单元将三通温控阀、海水冷却单元以及淡水冷却单元进行联控,引入外界实时的海水温度、冷却水需求量以及工作负荷来更为智能的调控海水冷却单元与淡水冷却单元的运行功率,在保持设备单元冷却需求的同时,实现节能效果。
