| Abstract | The purpose of this research is to predict annual electricity generation from the energy harvesting block from thermoelectric energy conversion from waste heat recovery. The energy harvesting block consists of thermoelectric generator and phase-change material. The waste heat on building exterior causes temperature difference between the exterior wall and the interior of the building. By implementing the energy harvesting block, the waste heat can be converted into electricity. To predict the amount of annual generation, representative monthly wall temperature profiles of April, July, October, and January (Spring, Summer, Autumn, and winter respectively) were calculated through TRNSYS 19. Peltier plate was used to mimic wall temperature by controlling plate temperature that is attached to the energy harvesting block. The result showed 205 Wh/m2, 30 Wh/m2, 223 Wh/m2, 281 Wh/m2 of electricity generation respectively for 4 seasons. The experiment showed feasibility of the energy harvesting block of generating electricity at night or day and regardless of the seasons. Total predicted annual electricity generation was 2217 Wh/m2. |
