<p>PROBLEM TO BE SOLVED: To cool down the brine in a serpentine tube by the cold of ice through the cold water at about 0 deg.C by always substituting the water located between ice and the tube for the cold water at about 0 deg.C in an ice storage tank at the time of the cooling operation of an ice storage device. SOLUTION: The lower end part of a hose 2 meandering vertically in the ice storage tank 3 is provided with an ice-melting aid 20 made of a metal formed with the lower part having a length equal to or greater than the thickness of the ice Ic formed around the tube 2. Then, the warmed brine Br melts the inside of the ice Ic around the tube 2 to open the upper end part, and melts the ice Ic in the vicinity of the ice-melting aid 20 so as to form a melting hole H, where air Fo is injected from the melting hole H in the underside of the lower end part of the ice Ic. Then, the cold water in the ice storage tank 3 is introduced to move upwards in a tubular ice-melting part T.</p> |
