The present invention relates to a vessel for a polar region having a cooling water control system, which can stably and continuously supply required seawater for cooling. The vessel for a polar region having a cooling water control system uses seawater to cool a heating device, and comprises: a sea chest to move seawater thereinto from the outside of the vessel to store the seawater; an engine room ballast tank formed on the hull of the vessel to store seawater; a heating device to generate heat and generate energy to operate the vessel; a heat exchanger to exchange heat between seawater and a heating medium heated by the heating device to cool the heating medium and heat the seawater; and a seawater main pump to supply seawater stored in the sea chest or the engine room ballast tank to the heat exchanger. The seawater entering through the sea chest is supplied to the heat exchanger by the seawater main pump in a normal time when ice is not formed on the sea chest, and the seawater stored in the engine room ballast tank is supplied to the heat exchanger by the seawater main pump in an emergency in which ice is formed on the sea chest.

    본 발명은 냉각수 제어 시스템을 갖는 극지용 선박에 관한 것으로, 발열 장치를 냉각시키기 위해 해수를 이용하는 냉각수 제어 시스템을 갖는 극지용 선박에 있어서, 선박의 외부로부터 해수를 유입시켜 저장하는 씨체스트와, 해수를 저장할 수 있도록 상기 선박의 선체에 형성되는 엔진룸 밸러스트 탱크와, 선박을 운용하기 위한 에너지를 생성하며 열이 발생하는 발열 장치와, 발열 장치에서 가열된 열매체와 해수를 열교환하여 열매체를 냉각시키고 해수를 가열하는 열교환기와, 씨체스트 또는 상기 엔진룸 밸러스트 탱크에 저장된 해수를 열교환기에 공급하는 해수 메인 펌프를 포함하고, 씨체스트에 결빙이 발생하지 않은 평상시에는 씨체스트를 통해 유입된 해수를 해수 메인 펌프에 의해 상기 열교환기에 공급하고, 씨체스트에 결빙이 발생한 비상시에는 엔진룸 밸러스트 탱크에 저장된 해수를 해수 메인 펌프에 의해 상기 열교환기에 공급한다.
