“…The maximum COP value was achieved as 4.7 with 2 V voltage and 5 W heating load. A significant decrease in COP was observed with the increase of the voltage, and it was stated that it reached the value of 0.13 when 12 V voltage was applied (Al-Chlaihawi et al , 2020). Different voltage and resistance values were used in a study to investigate the effect of thermal resistances on the performance of thermoelectric module.…”

Purpose The purpose of this paper is to experimentally and numerically investigate the cooling performance of the air-to-water thermoelectric cooling system under different working conditions. Design/methodology/approach An air-to-water thermoelectric cooling system was designed and manufactured according to the principle of discrete binary thermoelectric Peltier modules, and the thermal performance, heat transfer rate and average COP values were examined at different cooling water temperatures and voltages applied. Additionally, numerical simulations were performed by computational fluid dynamics approach to investigate the temperature distribution and airflow structure inside the cooling chamber. Findings Analyses were performed using experimental tests and numerical methods. It was concluded that, by decreasing the cooling water temperature from 20 to 5 °C, the average COP increases about 36%. The voltage analysis showed that the efficiency of the system does not always increase as the voltage rises; more importantly, the optimum voltage is different and depends on whether it is desired to increase COP or increase the cooling rate. Originality/value In the studies published in the field of thermoelectric cooling systems, little attention has been paid to the voltage applied and its relationship to other operating conditions. In most cases, the tests are performed at a constant voltage. In this study, several options, including applied voltage and cooling water temperature, were considered simultaneously and their effects on performance have been tested. It was found that under such studies, optimization work should be done to evaluate maximum performance in different working conditions.

Three-dimensional models of flat Peltier thermoelectric elements with different geometric shapes of semiconductor material: cube, cylinder, truncated pyramid and two monolithic truncated pyramids were created and studied. The volume of the semiconductor material is 8 mm2 and its height is 2 mm, with the height being a fixed distance between the contact plates (conductors) and the work plate in all models. In fact, all considered models are created from the same semiconductor material and are studied under the same initial conditions. For research and calculation of three-dimensional models, the finite element method was used in the ELCUT software complex. As a result of the conducted research, the main electrical and thermal parameters of the created models of flat thermoelectric elements were obtained, which include: current density and temperature on the conductors of thermoelectric elements. Comparative analysis of the obtained thermoelectric parameters made it possible to choose the most effective types of forms of semiconductor material to increase the efficiency of using the Peltier thermoelectric effect.
