Crossflow Thermoelectric Kitchen Hood System for Enhancing Sustainable Energy in Buildings
Downloads
Thermoelectric devices are capable of converting thermal energy into electrical energy. Waste heat recovery can be effectively achieved using thermoelectric modules. This study investigates the performance of thermoelectric generators integrated into a ducting-based kitchen hood system, with a focus on the impact of inlet temperature. A numerical simulation approach was employed and validated through comparison with previous studies. The validation results indicate a low error margin, with an error value below 5%. Simulations were conducted using ANSYS to analyze the effects of hot and cold airflow within a cross-section system. A steady-state simulation approach was employed to evaluate the thermal and fluid dynamic behavior of the system. Tetrahedral meshing was applied, resulting in a total of 25 × 10⁶ elements. The simulation results revealed that the temperature difference distribution formed a descending diagonal pattern from the lower-left to the upper-right region, which significantly influenced the output power generation of the system. The highest observed temperature difference was 313 K, while the lowest was 113 K, with the maximum power output recorded at 0.1903 W. The total power generated by the system, representing the cumulative output from all thermoelectric modules, reached 19.03 W at an inlet temperature of 600 K. The corresponding system efficiency was calculated to be 2.75%. These results indicate that inlet temperature significantly influences the generated power. Further studies investigating the combined effects of airflow velocity and inlet temperature are recommended to optimize system performance and enhance thermal-to-electric energy conversion efficiency. Additionally, experimental investigations are suggested as a means of further validation under real-world operating conditions.
