In order to build a high-performance OTEC (ocean thermal-energy conversion) plant and operate it efficiently, it is necessary to optimize design conditions, such as velocities of cold sea water and warm sea water passing through heat exchangers, working fluid temperatures for evaporation and condensation, and warm and cold sea water temperatures. In this paper, the total heat exchanger area per annual net power is used as an objective function. Calculated results are shown for a 1000 kW OTEC plant. Ammonia is used as the working fluid. Okinawa is selected as the construction site.
