The invention relates to the technical field of ship cooling system control, in particular to a ship fresh water cooling system with water supplied in a partitioned mode and a control method.The system comprises the steps that according to the fresh water demand quantity and/or heat exchange demand quantity of each fresh water cooling user, all the fresh water cooling users are divided into a preset number of cooling user partitions, the number of the cooling user partitions is the same as that of the partition water supply pipes; the output end of the fresh water pump in each cooling user partition is connected with the partition water supply pipe, each output end of the partition water supply pipe and one path of fresh water cooling regulating valve are connected to one fresh water cooling user, and the fresh water flow of the corresponding fresh water cooling user is adjusted by adjusting the opening degree of the fresh water cooling regulating valve. The fresh water pump in each water supply subarea is allowed to carry out rotating speed/flow regulation according to actual requirements, and the problem that the flow of multiple fresh water pumps in a fresh water cooling system of a header pipe-branch pipe structure is coupled and is difficult to regulate is solved.

    本发明涉及船舶冷却系统控制技术领域,尤其涉及一种分区供水的船舶淡水冷却系统及控制方法,所述系统包括:根据每个淡水冷却用户的淡水需求量和/或换热需求量,将所有所述淡水冷却用户划分为预设数目个的冷却用户分区,冷却用户分区的数量与所述分区供水管的数量相同;每个冷却用户分区内淡水泵的输出端与所述分区供水管连接,分区供水管的每个输出端均与一路淡水冷却调节阀连接至一个淡水冷却用户,通过调节淡水冷却调节阀的开度调整对应淡水冷却用户的淡水流量。本发明允许每个供水分区内的淡水泵按照实际需求进行转速/流量调节,消除了总管‑支管结构的淡水冷却系统中多台淡水泵流量相互耦合而难以调节的问题。
