The invention discloses an energy-saving central fresh water cooling system for ships. The energy-saving central fresh water cooling system comprises a central cooler, a monitoring and alarming system, a plurality of fresh water cooling pumps, a class-I cooling water user and class-II cooling water users, wherein the fresh water cooling pumps are connected in parallel to an outlet of the central cooler; outlets of fresh water cooling pumps are connected with the class-I cooling water user and the class-II cooling water users through a connecting pipeline; outlets of the class-I cooling water user and the class-II cooling water users are connected with an inlet of the central cooler; a pressure switch is arranged on the connecting pipeline; and control valves are arranged at water inlets ofthe class-I cooling water user and the class-II cooling water users respectively. According to the system, when certain cooling water users do not need to be in operation, electric butterfly valves corresponding to the cooling water users can be automatically shut down, so that the flow of cooling fresh water required by the central fresh water cooling system is reduced, the energy-saving purposeis achieved, and at the same time, the cavitation of the fresh water cooling pumps can also be avoided.
本发明公开了一种船舶中央冷却淡水节能系统,包括中央冷却器、监测报警系统、多台淡水冷却泵、第一类冷却水用户和第二类冷却水用户,多台淡水冷却泵并联连接在中央冷却器的出口,多台淡水冷却泵的出口通过连接管路与第一类冷却水用户和第二类冷却水用户相连,所述第一类冷却水用户和第二类冷却水用户的出口与中央冷却器的进口相连;连接管路上设置有压力开关,第一类冷却水用户和第二类冷却水用户的进水口处均设置有控制阀门。本发明的系统在某些冷却水用户不需要运行时可以自动关闭其对应的电动蝶阀,从而减少中央冷却水系统所需的冷却淡水流量,实现节能的目的,同时也能避免淡水冷却泵气蚀。
