“…In experiments conducted on a thermoelectric refrigerator, the COP value of the thermoelectric module was calculated as 0.74 when the temperature difference between the hot and cold sides was 32.7 °C. It has been reported that the internal temperature of this designed cooler model decreased to 10 in 72 min (Abderezzak et al , 2021).…”

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.

“…On the thermoelectric cooler the heat flow is absorbed from the cold side of the TEC and transported to the hot side depending on the coefficient of the TEC. In practice, there are two effects namely Joule heat and conducted heat, preventing ideal conditions in real applications [6][7][8][9].…”

This cooler box is designed to assist humans in getting cold drinks when traveling long distances by car. Semi-conductor cooler box components consist of TEC1-12706 and TEC1-12715, styrofoam box with a size of 53 × 31 × 43 cm, copper and aluminum processor heatsinks, fans with 12V and 1A voltage, acrylic, and retaining bolts. The lowest temperature that can be achieved by TEC1-12706 and TEC1-12715 is 23.7 • C which is reached in 60 min. The efficiency possessed by TEC with a heatsink 77.8%. Maintenance for the semi-conductor cooler box is very easy by not using a voltage that exceeds 12 V and it is not expected to disassemble the cooling component circuit consisting of the heatsink and TEC.
