초록

To reduce greenhouse gas emissions, renewable energy that does not require the use of fossil fuels is attracting increasing attention. In this study, a performance tester was designed and manufactured to develop an organic Rankine cycle power generation system for application to a small, 1 kW solar power generation system using solar heat as renewable energy, and a performance test was conducted. The performance of the organic Rankine cycle power generation system and a scroll expander, a key component of the system, was evaluated. Based on the results, the organic Rankine cycle power generation system could be improved. To test the application of this system to solar boilers, solar boilers for home use were installed. A prototype of the organic Rankine cycle power generation system was combined with a solar boiler to test its performance. This paper reports on the designed and manufactured performance test equipment. Performance test results, such as power, rated power, maximum power, system efficiency, and heating efficiency of the organic Rankine cycle power generation system are presented.
