The invention discloses a seawater centralized heat exchanger cooling water supply method and a ship, the seawater centralized heat exchanger cooling water supply method is applied to a seawater centralized heat exchanger cooling water supply system, the system comprises a controller, a power supply switch, a temperature sensor, a seawater pump, a seawater centralized heat exchanger and a fresh water loop, and the seawater pump, the seawater centralized heat exchanger and the fresh water loop are sequentially connected. Obtaining a fresh water outlet critical temperature of the seawater centralized heat exchanger; step S200, obtaining a first outlet water temperature of a fresh water outlet; s300, whether the seawater pump is started or stopped is judged; and step S400, when the seawater pump is switched from operation to shutdown, obtaining a second outlet water temperature of the fresh water outlet. According to the technical scheme, switching of the water supply modes of the seawater heat exchanger can be achieved only by measuring the fresh water outlet temperature of the hot side of the seawater centralized heat exchanger, and online correction is conducted on the fresh water outlet temperature critical value in the actual operation process of the ship seawater centralized heat exchanger; therefore, the sea water pump can be started or stopped according to actual requirements.

    本发明公开了一种海水集中换热器冷却水供应方法及船舶,应用于一种海水集中换热器冷却水供应系统,所述系统包括控制器、供电开关、温度传感器以及依次连接的海水泵、海水集中换热器和淡水回路,所述方法包括:步骤S100,获取海水集中换热器的淡水出水口临界温度;步骤S200,获取淡水出水口的第一出水温度;步骤S300,判断是否启动海水泵或停运海水泵;步骤S400,当海水泵由运行转为停运后,获取淡水出口的第二出水温度。本发明实施例的技术方案仅依赖测量海水集中换热器热侧淡水出口温度即能实现海水换热器供水方式的切换,且在船舶海水集中换热器实际运行过程中对淡水出口温度临界值进行在线校正,从而能够根据实际需求对海水泵进行启泵或停机。
