Abstract
In the new century, a Low-grade Thermal Energy Conversion (LTEC) which is Geothermal, Wasted Energy, Ocean Thermal Energy, is refocused on as one of the renewable energy to solve the global warming and the energy problem. This paper investigates on the maximum power and thermal efficiency of Rankine cycle in LTEC condition. The system performance of Rankine cycle is compared among working fluids of different properties. The maximum power with ammonia is largest of that with working fluids. The entropy generation rate with ammonia is smallest of that with working fluids.
