• In this paper, a non-pump cycle with pressurized modules driven by ocean thermal energy is proposed. The pressurized module is composed of an ejector and a two-phase heat exchanger to work instead of a pump, and a study of the non-pump cycle is carried out with R124 as the working mass. The working principle of the pressurized module and its two operating phases are described, the cycle period of the pressurized module is calculated, and the evaluation parameters of the non-pump cycle under different operating phases are analyzed and compared with the Rankine cycle. The results of the study show that the pressurized module power is equivalent to 0.119 kJ/kg of workpiece pumping work under the working conditions of this paper. The effective working ratio of the pressurized module is 55.51%, of which 44.14% of the whole cycle is spent in the filling stage, and the Rankine cycle driven by dual pressurized modules is sufficient to meet the demand of stable cycle operation.
