Abstract
Closed cycle is the most commonly used type of cycle in ocean thermal energy conversion. In order to recover and utilize the pressure energy of ammoniac-poor solution in the process of non-azeotropic working fluid circulation, this study proposes an ocean thermoelectric power generation cycle using an ejector, analyzes the working principle of the cycle and the model of key equipment, and builds the mathematical model and calculation process of the cycle based on the first law of thermodynamics. By calculating the performance of the circulating system, analyze and discuss the impact of changes in conditions such as seawater temperature, working fluid concentration, and circulating pressure on the net output power and thermal efficiency of the cycle.
