Provided in the present invention is an engine room air supply system, which, in a vessel having a main engine directly sucking air from the outside of the vessel, and a boiler generating steam by the waste heat of the main engine and a burner, can improve fuel efficiency of the total of the main engine and the boiler in case the temperature of the outside air is decreased. To this end, the engine room air supply system of the vessel, having a main engine (10) and a boiler (20) generating steam by the waste heat of the main engine (10) and a burner (25), comprises: an outboard air inlet (5) which is provided to suck air (6) from the outside of the ship; an air supply path (50) which is provided to directly supply the air (6) sucked from the outboard air inlet (5) into the main engine (10); an air inlet (8) in the engine room, which is disposed at the air supply path (50) so as to suck the air (9) from the inside of the engine room; an adjustment means (30) which adjusts the mixture ratio of the air (6) from the outside of the ship and the air (9) from the inside of the engine room; and a control means (40) which controls the adjustment means (30) to improve fuel efficiency which is the total of the fuel efficiency of the main engine (10) and the fuel efficiency of the boiler (20).

    [과제] 선외로부터 직접 공기를 흡인하는 주기관과, 주기관의 배열(排熱) 및 버너에 의해 증기를 생성하는 보일러를 구비한 선박에 있어서, 외기온 저하 시의 주기관과 보일러의 합산의 연비를 개선할 수 있는 기관실 급기 시스템을 제공한다. [해결수단] 주기관(10)과, 주기관(10)의 배열 및 버너(25)에 의해 증기를 생성하는 보일러(20)를 구비한 선박의 기관실 급기 시스템으로서, 선외로부터의 공기(6)를 인입하기 위한 선외 급기구(5)와, 선외 급기구(5)로부터 인입한 공기(6)를 주기관(10)에 직접 공급하기 위한 급기 경로(50)와, 급기 경로(50)에 마련된, 기관실 내부로부터의 공기(9)를 인입하기 위한 기관실내 급기구(8)와, 선외로부터의 공기(6)와 기관실 내부로부터의 공기(9)의 혼합 비율을 조정하는 조정 수단(30)과, 주기관(10)의 연비와 보일러(20)의 연비를 합산한 연비가 향상되도록 조정 수단(30)을 제어하는 제어 수단(40)을 갖는다.
