The present invention provides, a cooling water circulation pump operation optimization method applied to a ship cooling system (1), in which at an inverter temperature higher than the inverter temperature threshold, a pump variable duty output (b) of a pump controller (100) is applied differently depending on the inverter temperature, and by supplying a different flow rate of coolant to the inverter (60) by driving a coolant circulation pump (10) with a duty difference, the operation of the coolant circulation pump (10) can be controlled in detailed steps to minimize pump power consumption, and, in particular, by dividing the detailed stages of pump operation based on the inverter temperature, the pump operation time to achieve cooling performance is optimized.

    본 발명의 선박 냉각시스템(1)에 적용된 냉각수 순환 펌프 운용 최적화 방법은 인버터 온도 임계값(Threshold) 보다 높은 인버터 온도에서 펌프 제어기(100)의 펌프 가변 듀티 출력(b)이 인버터 온도별로 다르게 적용하고, 듀티 차이로 냉각수 순환 펌프(10)를 구동하여 인버터(60)에 대한 냉각수 유량을 다르게 공급함으로써 냉각수 순환 펌프(10)의 구동을 세부 단계로 제어하여 펌프 전력 소모량을 최소화할 수 있고, 특히 펌프 구동의 세부 단계를 인버터 온도 기반으로 구분함으로써 냉각 성능 효과를 얻기 위한 펌프 가동시간도 최적화되는 특징이 구현된다.
