This study was experimentally investigated to understand the ice making characteristics of ice on a coil type ice maker. The experiment was carried out under the following conditions which are the brine temperatures of $-10[^{\circ}C],\;-8[^{\circ}C],\;-6[^{\circ}C]$, brine flow velocities of 1.0[m/s], 1.4[m/s], 1.8[m/s] and initial water temperatures of $6[^{\circ}C],\;9[^{\circ}C],\;12[^{\circ}C]$, ect. The acquired conclusions shows: 1) Ice making amount is increased with decreasing in the temperature of brine. 2) Total ice making amount shows higher value in larger size coil. However, the ice making amount per heat transfer area is increased in smaller one. 3) The ice making amount is increased with decreasing in the initial water temperature. 4) It is cleared that the overturn of natural convection existed in this experimental result.
