“…They found that the cooling capacity of the TEAC system was ve-times lower than that of the conventional HVAC system at the same input power. Wang et al [15] designed and analyzed an automotive air-to-liquid TEAC system using a numerical model. To decrease thermal loss through thermal resistance, a 20-μm-thick anodized aluminum coating was used instead of ceramic plates.…”

Heating, ventilation, and air-conditioning (HVAC) systems are highly efficient and reliable but can negatively impact the environment. Environmentally friendly systems that could replace existing HVAC systems, such as thermoelectric cooling and heating systems, have been studied recently. Herein, an air-cooling system using thermoelectric modules (TEMs) was designed, manufactured, and evaluated in terms of its cooling performance. The optimal TEM was identified by analyzing QC–△T and V–I performance plots. The designed thermoelectric air-cooling (TEAC) system was composed of TEMs, heat sinks, and fans. Two versions were designed and the aim was to reduce the height of the system without compromising the cooling performance. The systems were tested in an insulated chamber having an inner volume of 250 × 250 × 250 mm3. After setting the temperature inside the chamber to 45°C, the time required for the system to reduce the temperature to 26°C was measured. Then, the developed system was mounted in a real car and the temperature decrease was recorded.

“…The numerical model was used to provide a complete design and analysis of an automotive air-toliquid TEAC system. Experiments were conducted to validate their design, which resulted in an overall efficiency of 1.55 (cooling capacity=1.55 kW) with the same 30 o C air and liquid intake temperatures [10]. They used the thermal isolation technique [11], which simulates the whole system and increases the coefficient of performance.…”

This paper discusses the results of tests done to investigate the performance of a thermoelectric air conditioner (TEAC). The TEAC is composed of twelve thermoelectric modules (TEMs). The TEMs were fixed to rectangular fin heat sinks on both their hot and cold sides. With an increased input voltage, the cooling capacity increased. At a 6 V input voltage flow, a suitable condition occurred. The rate of hot air flow was 0.48 kg/min, and the cooling capacity was 157.0 W, resulting in an outlet air temperature of 28 oC. The coefficient of performance (COP) was calculated and found to be 0.92. Exergy analysis is used to determine the energy flows and second law efficiencies of a TEMs system and its components. The exergy destruction and second law efficiency were observed to increase when the TEAC's input voltage was increased. The TEAC's maximum exergy efficiency was 0.35, which was low compared to the coefficient of performance.

“…This is close to a thermoelectric figure of merit of 0.5, which is easily obtainable with commercial TE coolers even considering heat exchanger losses. 7 Larger DT might be needed for humidity control (or required for refrigeration) where VCC systems can maintain good COP, whereas TE systems tend to have a constant j r .…”
