Abstract

Recently, due to limitation of $CO_2$ gas emission and increase of demand to reduce energy consumption, lots of researches are conducted to harvest wasted heat energy with a thermoelectric module to produce electricity by Seebeck effect. This study was conducted to analyze characteristics of the thermoelectric module to apply for a heat energy harvesting device. Thermoelectric module composed of bismuth telluride was tested with various temperature conditions to analyze thermoelectric behavior of the module. Power generation efficiency of the thermoelectric module for various temperature condition was analysed with both experimental and theoretical methods. From the results, an optimum condition to harvest wasted heat energy with the thermoelectric module more efficiently was proposed.

$CO_2$ 배출 규제와 에너지 소비 절감의 요구가 늘어남에 따라, 버려지는 열을 수확하여 전기를 생산하기 위한 열전발전 연구가 최근 활발히 이루어지고 있다. 본 연구에서는 폐열 에너지 회수장치로 사용하기 위한 열전모듈의 발전 특성을 분석하였다. Bismuth telluride로 제작된 열전모듈에 다양한 온도 조건을 부여하며 이에 따른 열전 거동을 분석하였다. 또한 다양한 온도 조건에서의 열전모듈의 발전 효율을 실험 및 이론에 의해 분석하였다. 이로 부터, 열전모듈로 열에너지를 보다 효율적으로 회수하기 위한 최적의 작동조건을 제시하였다.
