Abstract

 The Peltice device is a refrigerated drink dispenser using Peltier modules instead of a compressor for cooling. Peltier modules allow this project to be more sustainable by using water for cooling instead of harmful refrigerants and using solid-state cooling devices which would last longer than moving part devices. The Peltice system was able to bring the product’s temperature from 68 F to 49 F in 2 hours’ time. In addition, the data showed that the temperature in the Cooling Loop Water Reservoir was held at 33 F for about 2 hours before giving away quickly to the heat from the product. A test was then conducted to see how the Peltier modules affect the cooling action in the system since they are used to absorb the heat from the cooling loop before the water returns to the reservoir. The Peltice system without the Peltier modules was able to bring the product’s temperature from 66 F to 51 F in 2 hours’ time. The data showed that the temperature in the Cooling Loop Water Reservoir was held at 33.8 F for about 1 hour before giving away quickly to the heat from the product. Comparing Peltice with the modules on and off shows that the Peltier modules in this system acts as an “electric insulation” for the Cooling Loop reservoir. The modules prevent the temperature in the Cooling Loop water reservoir from rising linearly for nearly 2 hours while 1 hour without. This means a user will need to replace the ice in the Peltice system every 2 hours instead of 1 hour which makes Peltice more user friendly, but this extra hour allows the cooler to achieve a two degree Fahrenheit difference inside the cooler which is not much.
