Abstract : This paper represents the results of a capstone project that took place in the mechanical engineering department at Abu Dhabi Men’s College. Emphasis was placed on determining how much cooling can be stored in a 10 L water tank from 3 water thermoelectric coolers (WTCs) connected thermally in series. The results obtained were analyzed for 3 different connecting scenarios, a) one WTC, b) 2 WTCs connected in series, 3 WTCs connected in series and two different mass flow rates of 0.02 kg/s and 0.04 kg/s. A decrease in the water storage tank temperature with time was shown under all the conditions and scenarios the experiments were conducted. On the other hand an increase in the amount of cooling capacity in the water storage tank was observed with time. Of interest the results showed that the rate with which the storage tank temperature gradient and consequently the amount of cooling stored decreased as the number of the WTCs used increased.

Keywords : Thermoelectric water cooler, Cooling capacity, Stored energy.
