Analisis Laju Pendinginan pada Kulkas Thermoelektrik Super Cooler Dibandingkan Sistem Pendingin Konvensional Menggunakan Gas Freon

Abstract

It has been designed and analyzed by using a cooling device which was have a Peltier cooler hot side and a cold side using a principle works of Peltier effect . These study analyze and compare the rate-based thermoelectric cooling refrigerator cooler than conventional cooling systems using freon gas. These study also focused on utilizing conventional refrigerator (Air Freon) that have been damaged as the peltier coolers. By using the DC fan on the cooler side to accelerate cooling and the hot side to dissipate heat on the cold side, peltier cooler is able to match Freon coolant. Both cooling are capable of reaching a temperature of -210C at the initial temperature of 270C. With the variation of the volume of water load (1 kg, 2 kg, 3 kg, 4 kg, 5 kg, 6 kg, 7 kg, 8 kg, 9 kg, 10 kg) both Freon cooling and cooling Peltier take each (50 minutes and 70 minutes, 99 minutes and 128 minutes, 148 minutes and 178 minutes, 197 minutes and 236 minutes, 247 minutes and 291 minutes, 296 minutes and 349 minutes, 341 minutes and 404 minutes, 398 minutes and 465 minutes, 441 minutes and 527 minutes, 493 minutes and 576 minutes). From the results obtained, it can be concluded that the refrigerant Freon is still far better than the alkaline cooling Peltier component.
