ICE HEAT ACCUMULATING TANK DEVICE

摘要

PURPOSE:To cause a refrigerant to flow to a heat accumulating tank in a laminar air flow state, to keep temperature distribution in the tank in a uniform state, and to improve thermal efficiency by a method wherein a discharge pipe is extended from an ice making machine to the heat accumulating tank, and discharge holes are formed in the peripheral surface of the discharge pipe positioned in the heat accumulating tank. CONSTITUTION:A discharge pipe 5 is formed in the lower side of a tank body 16 of a heat accumulating tank and extended from an ice making machine to a position located in a level higher than that of a water suction pipe 4 and a feed pipe 6. The discharge pipe 5 is formed with four pipes the tips of which are closed, and arranged in parallel to each other in the heat accumulating tank in which the pipes are extended. A plurality of oblong hole 27 serving as an up-discharge hole are formed on the upper side of the peripheral surface of each pipe at intervals of a specified distance in the longitudinal direction of a pipe. The oblong hole 27 is formed in size determined through calculation of the hole part so that an influence is prevented from being exercised on surroundings by a velocity of flow when ice R delivered through the oblong hole 27 is raised 1m in order to prevent the generation of a turbulent flow at the lower part of the interior of the tank due to the velocity of flow of the ice R. This constitution generates a laminar air flow in which an influence is prevented from being exercised on the periphery of the interior of the tank by the velocity of flow in a position where the ice R delivered through the oblong hole 27 is raised 1m.
