Abstract

Recently, there has been increasing interest in the efficient use of energy due to policies related to the reduction of greenhouse gas. This paper suggests a highly efficient sea water cooling system for the load-dependent control of a seawater pump depending on the load, to improve energy efficiency of the warship. This study models the propulsion diesel engine and simulation reflecting the characteristics of the warship operation state that checked the performance of high efficiency sea water cooling system. The simulation results revealed the cooling system of high efficiency with energy savings of approximately 53% compared to the existing cooling systems. These results can be used to improve the performance of the cooling system of the warship propulsion diesel engine in the future.

최근 대두되는 선박배기가스 저감 등의 환경정책으로 인하여 에너지의 효율적 이용에 관심이 증가하고 있다. 본 논문에서는 함정의 에너지 효율 향상을 위하여 사용 부하에 따라 해수펌프를 제어하는 고효율 해수냉각시스템을 제안한다. 본 논문에서는 제안하는 시스템의 효과를 알아보기 위하여 추진 디젤기관의 냉각시스템을 모델링 하고 함정 운항특성을 고려한 시뮬레이션을 수행하였다. 시뮬레이션 결과 제안한 고효율 해수냉각시스템이 기존 해수냉각시스템에 비하여 약 53%의 에너지 절감효과가 있었다. 본 연구 결과는 향후 함정 추진 디젤기관의 해수냉각시스템의 성능 향상에 유용한 자료로 활용될 수 있다.
