| Abstract | Ocean Thermal Energy Conversion (OTEC) plant generates electricity by using 20～27 o C temperature difference between warm surface seawater at surface and cold deep seawater. OTEC is environmentfriendly and semi-permanent energy sources because its heat source is seawater warmed by the sun and no incineration，and no CO2 emission can be achieved. In this paper, it is focused on the cycle that is removed the regenerator, the absorber, and the diffuser from conventional Kalina cycle, and is returned the liquid working fluid separated with the separator to the inlet of the evaporator. The cycle was called R-cycle. It is compared Ncycle with a conventional Karina cycle by the numerical simulation. Two computational methods are used the program that is not treated the heat transfer performance of each heat exchanger, and other program that is treat the heat transfer performance of each heat exchanger and the condition of heat source. As a result, a past Kalina cycle was more efficient even though which calculation was used. |
