The present invention provides a cooling water system of an engine room on a ship which groups cooling flow to control flow rate and temperature, thereby optimizing control of a variable frequency drive (VFD) motor device, accordingly maximizing energy saving effect of a pure water pump and a sea water pump. In addition, the present invention makes a scavenging air cooler of a main engine perform cooling flow independently to manage temperature two dimensionally, thereby enhancing cylinder states such as saving fuel consumption of the main engine and preventing internal corrosion of a main engine cylinder. The cooling water system of the engine room on the ship according to the present invention comprises: a central pure water cooler exchanging heat between cooling water of an engine and sea water; a main engine group including the main engine for propulsion; the pure water pump of the main engine supplying the cooling water to the main engine; an auxiliary engine group including a power generation engine; and a pure water pump of the power generation engine supplying cooling water to the power generation engine, wherein the pure water pump of the main engine and the pure water pump of the power generation engine are provided with the VFD motor device.

    본 발명은 선박 엔진룸의 냉각수 시스템으로, 냉각 흐름을 그룹화하여 유량과 온도를 제어함으로써 VFD 모터장치의 제어를 최적화할 수 있고, 그에 따라 청수 펌프와 해수 펌프의 에너지 절감 효과를 극대화할 수 있다. 또한, 메인 엔진의 소기 공기 쿨러의 냉각 흐름을 독립화하여 온도를 이원화 관리함으로써 메인 엔진의 연료 소모량을 절감하고, 메인 엔진 실린더의 내부 부식을 방지하는 등 실린더의 상태를 향상시킬 수 있다. 본 발명에 따른 선박 엔진룸의 냉각수 시스템은 엔진의 냉각수와 해수의 열교환이 이루어지는 중앙 청수 쿨러; 추진용 메인 엔진을 포함하는 메인 엔진 그룹; 상기 메인 엔진으로 냉각수를 공급하는 메인 엔진 청수 펌프; 발전 엔진을 포함하는 보조 엔진 그룹; 및 상기 발전 엔진으로 냉각수를 공급하는 발전 엔진 청수 펌프를 포함하되, 상기 메인 청수 펌프와 발전 엔진 청수 펌프에는 VFD(Variable Frequency Drive) 모터장치가 각각 구비되는 것을 특징으로 한다.
