摘要

Use of air conditioning (A/C) is one of the most important factors influencing vehicle fuel consumption (FC). Therefore, Therefore, the study aims to design a comprehensive thermoelectric cooler for air conditioning (TEC-A/C) system powered by a solar photovoltaic (PV) and evaluate its performance on a light vehicle. The TEC-A/C system was linked with a 410-watt flexible PV and battery to supply the required energy and the application of the MPPT system which keeps the PV system’s maximum output steady. An experimental presentation of the cooling properties of the TEC-A/C system is made with four TEC modules. The TEC-A/C system with 4-TEMs mode was more effective than the 2-TEMs mode and had higher power usage. The TEC-A/C system powered by solar PV was tested and evaluated in the vehicle under the cooling conditions. The results show that the duration time it takes for the vehicle cabin temperature with the TEC-A/C system to reach 24 °C is 4.23 and 5.94 min for 4-TEM and 2-TEM modes, respectively. Results indicate that the conventional A/C is quick to respond and takes approximately 25.7% and 47.2% less time to cool the car’s interior compared to the TEC-A/C system with 4-TEM and 2-TEM modes, respectively. The vehicle FC with the novel TEC-A/C powered by solar PV was lower than that of the conventional A/C system (baseline) throughout the vehicle speed range, the TEC-A/C system improved FC by 9.62%: 41.27%, depending on the vehicle speed. Lastly, the proposed TEC-A/C system driven by solar PV is very economical.
