The Efficiency of Peltier-assisted water cooler.

Abstract

The purpose of this research is to develop the production of Peltier-assisted water cooler by investigating the efficiency and the product applicability. This water cooler is designed to use the Peltier device as the thermoelectric cooling instead of the conventional refrigerator that uses the vapor-compression refrigeration system (VCRS). Furthermore, typical refrigerators tend to be bulky, expensive, and require costly maintenance. This water cooler, therefore, is designed to be lightweight, energy efficient, low production cost, and can be easily assembled. In addition, the cooler can be utilized in the area where power grid is inaccessible as it can be connected to automobile power connector or even the solar energy (e.g. ranch, farm, or disaster area). Based on statistical data, Peltier-assisted water cooler is able to cool the water down to below 10 °C, average score(X) of 3.92 and standard deviation (SD) of 0.45. The product applicability is in “good” category, =4.45 and SD=0.80.
