본 발명은 다수의 VSD 해수 펌프가 사용될 때 VSD 해수 펌프와 밸브를 동시에 제어하여 유량을 조절하게 되어 에너지를 절감할 수 있는 청수 냉각 시스템에 관한 것으로, 해수흡입통로를 통해 해수를 유입하여 순환시키는 복수개의 VSD 해수 펌프와, 상기 VSD 해수 펌프의 후단에 연결되어 VSD 해수 펌프의 전단부와 후단부의 압력 차이를 감지하여 제어기로 신호를 보내는 차압 센서와, 상기 VSD 해수 펌프로부터 해수를 공급받아 해수와 청수를 열교환하는 해수 쿨러와, 상기 해수 쿨러에서 냉각된 청수를 순환시켜 냉각수를 이송하는 청수 펌프와, 상기 해수 쿨러에 연결되어 사용된 청수의 온도를 감지하여 해수의 유량을 결정해주는 온도감지부와, 상기 해수 쿨러에서 배출되는 배출 압력을 조절하는 압력 조절 밸브를 포함한다.

    The present invention relates to a clean water cooling system which simultaneously controls a VSD seawater pump and a valve when a plurality of VSD seawater pumps are used to adjust a flow rate, thereby reducing energy. The water cooling system comprises: a plurality of VSD seawater pumps introducing seawater through a seawater absorbing passage and circulate the same; a differential pressure sensor connected to the rear end of the VSD seawater pump, detecting a pressure difference between a front end portion and a rear end portion of the VSD seawater pumps, and transmitting a signal to a controller; a seawater cooler receiving seawater from the VSD seawater pump and transferring heat between seawater and clean water; a clean water pump circulating clean water cooled in the seawater cooler and transferring cooling water; a temperature detection unit connected to the seawater cooler and detecting the temperature of used clean water to determine the flow rate of the seawater; and a pressure adjusting valve adjusting discharge pressure discharged from the seawater cooler.
