Abstract
Thermoelectric cooling is an alternative cooling technology with several desirable attributes, such as low weight, compactness and absence of a working fluid. It, however, has several limitations regarding performance, energy consumption and achievable temperature span. Because of this, several solutions have been proposed to try and improve the performance of this technology and make it more competitive in cooling applications. Among these solutions, some studies have proposed arranging the modules in series in order to achieve higher temperature spans and higher cooling capacities. In this work, a mathematical model was developed to simulate the operation of the modules in this configuration and compare it with the performance of the same number of modules operating independently (stacked). The results showed that the parallel configuration had a better performance than the series configuration, with the difference increasing with the number of modules. Meanwhile, the main advantage of the series configuration is its lower complexity. The parallel configuration, however, may be more affected by the fan losses, with further studies being needed to better quantify this effect on the performance.
