Performance of Water Thermoelectric Cooler Connected in Series: An Experimental Study

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.
