Abstract: The study shows the experimental and theoretical analysis of a fast beverage chiller based on the principle of a thermoelectric refrigeration and it was discovered theoretically that for a cooling time of 2 min and a beverage size of 474 mL (16 Oz), 6 TEC modules and hence 12 heat sinks (one for each side of the TEC module) were needed. However by increasing cooling time to 4 min and decreasing beverage size to 325 mL, 4 TEC modules and hence 8 heat sinks could be used. Comparison were also made between the beverage chiller’s cooling time with cooling times obtained from the freezer space and cold space of a household refrigerator. All three tests were carried out on 325 mL of water in a glass jar. The result shows that for the refrigerator freezer space, the temperature of the water decreased linearly with increasing time. However for the beverage chiller, the water temperature decreased exponentially with increasing time.
