Abstract
As a renewable energy, solar energy is hard to use because of low energy density. However, Organic Rankine Cycle power generation systems (ORC) are very suitable to use solar energy, since ORC can select different working fluids to match different kinds of heat conditions. Moreover, the ORC is more stable, highly reliable, and with higher system efficiency then other kinds of low-thermal power generation systems. As a result, solar heat energy combined with ORC is used in this study. Then we build a solar ORC simulation model to analyze the solar irradiation for five areas in Taiwan (Hsin-Chu, Hua-Lien, Su-ao, Peng-Hu, and Heng -Chun). Once establishing the model in the study, we can set the thermal properties and the boundary conditions for the system. Consequently, we can find the optimization parameters for Taiwan environmental conditions. Using small community of Taiwan as scenario simulation in the study, we set the collector area of 50 square meters, and select R245fa as ORC working fluid. Also, we set the evaporating temperature of 140℃ and the solar heat collector temperature of 190℃, to generate 3kW of power. Finally, we can construct a Solar Organic Rankine Cycle database to study future solar ORC systems in Taiwan
