Abstract

Effect of thermoelectric module-based energy harvesting blocks arrangement and resistance on power generation Jae-Won Joung Dept. of Architectural Engineering The Graduate School Hanyang University Energy can be harvested from various energy sources within a building. A thermoelectric generator-assisted energy harvesting block was proposed in this study, with the goal of utilizing the waste heat source of the building's outside wall. A thermoelectric generator and phase change material are used in the energy harvesting block to convert waste heat from the building envelope and heat flux from the outside into electricity. An energy collecting block wall requires the use of multiple energy harvesting blocks. Thus, the electrical configurations of several energy harvesting blocks, as well as their impacts on external resistance, were investigated. A series array, parallel array, and combination array were used in the layouts. Experiments with a total of nine examples were carried out by connecting 1.6, 15, and 60 with the same external resistance as the internal resistance of each array. In December, the temperature and closed-circuit voltage were monitored using the sol- air temperature profile. As a result, the external resistor connected had a greater effect on voltage and current than the array type. When 60 was linked to the series arrangement, the highest generated energy was 0.837Wh/day. The series structure was the most advantageous in terms of generated energy.
