Abstract

This study has been carried out to develop TM (Thermal to Mechanical) conversion systems for electric power generation using one of the Low Temperature Differential (LTD) Stirling engines called MM-7 capable of harnessing low temperature waste heat whose temperature is only $20{\sim}30^{\circ}C$ above the ambient. Measurements were made on the torque and rpm for a number of temperature differentials between the engine hot and cold ends, which could be effectively applied in developing the most suitable configuration for the high performance TM (Thermal to Mechanical) conversion system.

본 연구는 주위의 온도보다 약 $20{\sim}30^{\circ}C$ 밖에 높지 않은 저온폐열을 활용하기 위한 TM(Thermal to Mechanical) 발전변환기의 개발을 위하여 저온도차 스털링엔진의 하나인 MM-7에 대한 성능실측 연구를 수행하였다. 스털링엔진의 흡열부와 방열부의 온도차에 대한 토크 및 분당회전수를 측정하고 이를 바탕으로 MM-7 엔진의 출력을 산출하였으며, 이를 통하여 효율적인 TM발전변환기의 개발 방안을 모색하였다.
