열전소자 기반 에너지 하베스팅 블럭의 건물외피 적용시 발전량 예측

Abstract

The purpose of this research is to predict annual electricity generation from the energy harvesting block when it is installed on exterior wall of a building. By incorporating thermoelectric generator and phase change material, the energy harvesting block can passively generate electricity from waste heat. Since exterior walls of buildings has waste heat that is accumulated in daytime and dissipated during night, which makes the waste heat on walls be unused, the energy harvesting block is installed on building walls to collect the unused heat. The experiment to evaluate the electricity generation was done according to the representative wall temperature ranges of summer, winter and of a day that has the biggest range. Experimental results showed that the electricity generation depended on the magnitude of the range and both summer and winter condition results showed 0.090 Wh of electricity generated for a day. Because a single energy harvesting block can generate 0.090 Wh of electricity, when the energy harvesting block is installed in a scale of 1 m2, total 5,810 Wh can be generated for a year.
