초록

탄소저감 기술과 함께 에너지 효율 향상에 대한 관심이 증가하고 있다. 엔진에서 대기로 방출되는 배기에너지는 전체에너지의 30%가 넘는 많은 양이며 배기열을 회수하기 위한 많은 연구가 진행되고 있다. 본 연구에서는 선행연구를 통하여 제시한 디젤엔진에서의 최적 열 회수 조건에 대한 랭킨사이클을 분석하였다. 그 결과 질량유량비와 압력비가 각각 0.6, 0.7 일 때 엑서지 효율과 출력은 0.53, 1.43 kW을 나타내었다.

Interest in the energy efficiency and carbon reduction technology is increasing. Many studies have done on the technologies of heat recovery systems, because over 30% of the total energy is released into the atmosphere with the exhaust gas flow. In this study, the Rankine cycle is analyzed in the optimum conditions given through the previous work. The result shows that the exergy efficiency is 0.53 and the output is 1.43 kW at the condition of the pressure ratio of 0.6 and the mass flow rate of 0.7.
