- Abstract
- This study proposes the method of improving the system efficiency of Ocean Thermal Energy Conversion (OTEC) system. A liquid-vapor ejector and the motive pump pressurizing the motive working fluid of the ejector are applied to Kalina cycle, and this cycle is newly named EP-Kalina cycle. Simulations with designed conditions are conducted to compare newly proposed cycles with basic OTEC cycle and Kalina cycle with an ejector. As a result, system efficiency of EP-Kalina cycle presents relatively 49.7% higher than basic OTEC cycle, and 31.1% higher than EKalina cycle.
