Coefficient of performance optimization of a single stage thermoelectric cooler

In thermoelectric coolers (TECs) applied external voltage potential is generated to a temperature difference based on the Peltier effect. Main and basic structure of TECs is in the form of single stage device. Due to the low efficiency, especially low coefficient of performance (COP) of thermoelectric coolers, optimal design of geometrical parameters of such devices is vital. For this purpose, usually optimization algorithms are used. Therefore, in this research, chemical reaction optimization algorithm (CRO) is used in order to optimal design of structure of single stage thermoelectric cooler. CRO algorithm is a novel optimization scheme inspired form chemical reaction mechanisms. The results of the research are compared with previous data obtained using other optimization algorithm. Comparison of the results shows that application of CRO algorithm results in enhancement of COP of the system. Therefore, CRO algorithm proposed in this research could be used for better design of single stage TECs to achieve higher efficiency and coefficient of performance of the system.
