Study on the Efficiency of Pilot OTEC System depend on Temperature Variation between Surface and Deep Seawater
Abstract
The energy is the basis for almost all industrial activities and domestic needs. But recently there are increasing concerns internationally over environmental problems and consequent climate change caused by the excessive use of fossil fuels. Futhermore the price of crude oil is increasing steadily with unstable supplies. In order to solve these national energy problems, the utilization of Ocean Energy is introduced as one of the best alternative technologies for the future. Ocean Thermal Energy Conversion(OTEC) is a system of converting thermal energy in electricity by using the temperature difference between warm water at the surface of the ocean and cold water at it's depth. 6kW OTEC-PV pilot plant has been installed. Temperature differences of 20~25℃ have been utilized for plant operations, when R22 is used as a working fluid. The system is mainly composed of low pressure turbine, plate type heat exchanger, and pumps.
This study analyzed the efficiency of only OTEC system such as gross power, net power and objective function when temperature differences varied between 20℃ and 25℃.
