Abstract

PURPOSE: To prevent the rise of the temperature of cooling water in a fish hold by forming a heat-insulating material layer covering the water surface of cooling water filled in a fish hold with plural heat-insulating blocks of independent foamed bodies formed in a specified size.
CONSTITUTION: Each wall of a fish hold 2 which has an opening in a deck 2 is covered with a heat-insulating material, except for the part of a hatch 3. Inside the fish hold 2, a heat exchanger for a cooling device is installed, though not being shown in the figure, and the hold is filled with cooling water. On the surface of the cooling water in the hold 2, plural heat-insulating blocks made up of independent foamed bodies such as polystyrene and formed in the length of 30W100mm are placed in a floating condition, forming a heat-insulating material layer 5 on the surface of water. By this layer 5, the rise of temperature on the surface of cooling water is to be prevented. Although the device used is simple as stated in the above, it can display remarkable effect.
