해수펌프(111)의 작동에 의해 해수탱크(112)로부터 쿨러(110)로 해수가 공급되면, 쿨러(110)는 냉각수펌프(122,132)의 작동에 의해 냉각수순환라인(121,131)을 따라 순환 공급되는 냉각수를 냉각시킨다.When seawater is supplied from the seawater tank 112 to the cooler 110 by the operation of the seawater pump 111, the cooler 110 is circulated and supplied along the coolant circulation lines 121 and 131 by the operation of the coolant pumps 122 and 132. Cool the cooling water.

쿨러(110)에 의해 냉각된 냉각수는 냉각수순환라인(121,131)을 따라 선박에서 냉각이 필요한 냉각대상물(1,2), 즉 쇄빙 장비와 엔진으로 각각 순환 공급됨으로써 이들을 냉각시킨다. 이 때, 제어부(160)는 제 1 및 제 2 온도센서(140,150)로부터 각각 출력되는 감지신호를 수신받아 냉각대상물(1,2)로 공급되는 냉각수의 온도를 파악하여 냉각수가 정해진 온도, 예컨대, 쇄빙 장비인 제 1 냉각대상물(1)의 경우 20 ∼ 30℃, 바람직하게는 25℃에 해당되도록 제 1 냉각수순환수단(120)의 밸브수단(124)을 제어하고, 선박의 엔진인 제 2 냉각대상물(2)의 경우 31 ∼ 41℃, 바람직하게는 36℃에 해당되도록 제 2 냉각수순환수단(130)의 밸브수단(134)을 제어한다.The coolant cooled by the cooler 110 is circulated and supplied to the cooling objects 1 and 2 that need to be cooled in the ship along the coolant circulation lines 121 and 131, that is, the icebreaking equipment and the engine, respectively. At this time, the controller 160 receives the sensing signals output from the first and second temperature sensors 140 and 150, respectively, and grasps the temperature of the cooling water supplied to the cooling objects 1 and 2 to determine the temperature of the cooling water, for example, In the case of the first cooling object 1, which is ice-breaking equipment, the valve means 124 of the first cooling water circulating means 120 is controlled to correspond to 20 to 30 ° C., preferably 25 ° C., and second cooling, which is an engine of the ship, is performed. In the case of the object 2, the valve means 134 of the second cooling water circulation means 130 is controlled to correspond to 31 to 41 ° C, preferably 36 ° C.

제어부(160)는 냉각대상물(1,2)로 공급되는 냉각수의 온도를 제어하기 위하여 쿨러(110)로부터 냉각대상물(1,2)로 공급되는 냉각 상태의 냉각수 양을 증가시킴과 아울러 냉각대상물(1,2)로부터 쿨러(110)를 바이패스하여 다시 냉각대상물(1,2)로 공급되는 가열 상태의 냉각수 양을 감소시키도록 밸브수단(124,134)을 제어함으로써 냉각대상물(1,2) 각각으로 공급되는 냉각수의 온도를 높이게 되며, 이와 반대로 밸브수단(124,134)을 제어함으로써 냉각대상물(1,2) 각각으로 공급되는 냉각수의 온도를 낮추게 된다. The controller 160 increases the amount of cooling water supplied from the cooler 110 to the cooling targets 1 and 2 in order to control the temperature of the cooling water supplied to the cooling targets 1, 2 and the cooling target ( By bypassing the cooler 110 from 1,2), the valve means 124, 134 are controlled to reduce the amount of cooling water in the heated state supplied to the cooling objects 1, 2 to the cooling objects 1, 2, respectively. The temperature of the cooling water supplied is increased, and conversely, the temperature of the cooling water supplied to each of the cooling objects 1 and 2 is reduced by controlling the valve means 124 and 134.

한편, 본 발명에 따른 해수를 이용하는 선박의 냉각장치(100)는 해수를 냉매로서 사용할 수 있는 저온의 해역이나 극한 지역을 항해시 그 활용성이 증가하게 된다. On the other hand, the cooling device 100 of the vessel using the sea water according to the present invention will increase its utility when sailing in low-temperature sea areas or extreme areas that can use the sea water as a refrigerant.
