The invention provides an operation method and an operation control device of a ship centralized cooling system. The centralized cooling system comprises a fresh water loop, the fresh water loop is used for flowing through a heat source user and a centralized cooler, and a fresh water pump is arranged on the fresh water loop. The operation method of the ship centralized cooling system comprises the steps that the actual operation speed of the fresh water pump is set; change of heat load of the heat source user is obtained; and the concentration of the nano-particles in the fresh water loop is adjusted according to the actual operation speed of the fresh water pump and the change of the heat load of the heat source user so as to meet the heat load requirement of the heat source user. The operation method is simple and convenient to operate, the change of the load in the fresh water loop can be realized without changing the operation of equipment in the system, such as a fresh water pump, not only is the influence of the load change on the operation condition of the equipment reduced, but also the efficiency of the system is improved, the noise is reduced, and the centralized cooling system can operate efficiently, quietly and reliably.

    本发明提供一种船舶集中冷却系统的运行方法及运行控制装置,其中,所述集中冷却系统包括淡水回路,所述淡水回路用于流经热源用户和集中冷却器,且所述淡水回路上设有淡水泵,所述船舶集中冷却系统的运行方法包括:设定所述淡水泵的实际运转速度;获取热源用户热负荷的变化;根据所述淡水泵的实际运转速度以及所述热源用户热负荷的变化调节所述淡水回路内的纳米颗粒浓度,以满足所述热源用户热负荷需求。该运行方法,简单、操作方便,不需要改变系统内设备例如淡水泵的运行即可实现淡水回路内负荷的变化,不仅降低了因负荷变化对设备运行工况的影响,也提高了系统的效率,降低噪声,使集中冷却系统高效、安静、可靠的运行。
