The present invention relates to a combustion air cooling system for a vessel engine, which cools combustion air of an engine in accordance with a principle in which engine efficiency is improved as temperature of the air necessary for combustion of a fuel in the engine of a vessel is low, and a method for the same. According to the present invention, the combustion air cooling system for a vessel engine includes: a combustion air cooler cooling the combustion air of the engine; at least a first cooler cooling and circulating fresh water needed in the vessel by a first refrigerant; a pump for cooling the combustion air, which pumps and supplies the fresh air cooled in the first cooler as much as the amount of the fresh air necessary in the combustion air cooler; a pump for a demanding place, which pumps and supplies the fresh water cooled in the first cooler as much as the amount of the fresh water necessary in other fresh water demanding place in the vessel except for the combustion air cooler; and a second cooler cooling the fresh water by a second refrigerant. The fresh water discharged after cooling the combustion air in the combustion air cooler is cooled by either the first cooler or the second cooler. The fresh water is circulated by the pump for cooling the combustion air.

    본 발명은 선박의 엔진에서 연료의 연소에 필요한 공기의 온도가 낮으면 엔진 효율이 향상되는 원리에 따라 엔진의 연소공기를 냉각시키는 시스템 및 방법에 관한 것이다. 본 발명의 따른 선박용 엔진 연소공기 냉각 시스템은, 엔진의 연소공기를 냉각시키는 연소공기 쿨러; 선박에서 필요로 하는 청수를 제1 냉매로 냉각시켜 순환시키는 적어도 하나 이상의 제1 쿨러; 상기 제1 쿨러에서 냉각된 청수를 상기 연소공기 쿨러에서 필요로 하는 만큼 펌핑하여 공급하는 연소공기 냉각용 펌프; 상기 제1 쿨러에서 냉각된 청수를 상기 연소공기 쿨러를 제외한 선박 내 다른 청수 수요처에서 필요로 하는 만큼 펌핑하여 공급하는 수요처용 펌프; 및 상기 청수를 제2 냉매로 냉각시키는 제2 쿨러;를 더 포함하여, 상기 연소공기 쿨러에서 연소공기를 냉각시키고 배출되는 청수는, 상기 제1 쿨러 또는 제2 쿨러 중 어느 하나에서 냉각되고, 상기 연소공기 냉각용 펌프에 의해 순환하는 것을 특징으로 한다.
