article description
The main objective of this paper is to study the thermal resistances of two components of a thermoelectric ice maker installed in a no-frost refrigerator, in order to optimize ice production. The study is conducted using a computational model developed by the Thermal and Fluids Research Group of the Public University of Navarre, as explained and validated in previous papers. Firstly, three dissipators with different space between the fins are simulated using Fluent computational fluid dynamics software to study their influence on both ice production and refrigerator performance. The computational model predicts maximum ice production of 2.82 kg/day with less than 7 W extra electric power consumption, though these values depend to a great extent on the cooling and freezing power of the refrigerator. Secondly, this work focuses on reducing the size of the components in order to save raw materials and reduce the cost of the device. The computational model predicts that the final design produces 2.42 kg/day of ice, saves 65% of raw materials, and reduces by 50% the cost assigned to the thermoelectric modules. © 2011 TMS.
