Cooling system using deep seawater

Abstract

An object of the present invention is to provide a cooling system using deep seawater capable of reducing the cost. The cooling system using deep seawater includes an water intake pump 2 for pumping up deep seawater from the sea, a heat exchanger 3 for exchanging heat between a coolant and cold energy of the pumped-up deep seawater, a first deep seawater pipe 10 for supplying the deep seawater to the heat exchanger 3 from the water intake pump 2 , and a second deep seawater pipe 11 which is in communication with the first deep seawater pipe 10 and discharges the deep seawater into the sea, wherein the first deep seawater pipe 10 and the second deep seawater pipe 11 are laid in close proximity by a predetermined distance in the ground.

1 . A cooling system using deep seawater, comprising:
 a pump for pumping up deep seawater from the sea;   a heat exchanger for exchanging heat between a coolant and cold energy of the pumped-up deep seawater;   a first deep seawater pipe for supplying the deep seawater to the heat exchanger from the pump; and   a second deep seawater pipe which is in communication with the first deep seawater pipe and discharges the deep seawater into the sea,   wherein the first deep seawater pipe and the second deep seawater pipe are laid in close proximity by a predetermined distance in the ground.   
     
     
         2 . The cooling system using deep seawater according to  claim 1 ,
 wherein the first deep seawater pipe and the second deep seawater pipe are laid one above the other in the ground, while the second deep seawater pipe is laid on the ground surface side, and the first deep seawater pipe is laid on the lower side of the second deep seawater pipe.   
     
     
         3 . The cooling system using deep seawater according to  claim 1 ,
 wherein the first deep seawater pipe is insulated with heat-insulating material.   
     
     
         4 . The cooling system using deep seawater according to  claim 1 ,
 wherein the predetermined distance is determined based on temperature of the deep seawater which is discharged into the sea from the second deep seawater pipe.   
     
     
         5 . The cooling system using deep seawater according to  claim 1 ,
 wherein the pump is installed in a position lower than sea level.
