A novel multi-generation hybrid system is proposed and analyzed in details from the viewpoint of thermodynamics. Using a zeotropic mixture as working fluid, the system consists of a power and ejector refrigeration cycle as well as a desalination system based on humidification and dehumidification processes. A parametric study is performed to specify the decision variables influencing the system performance prior to the optimization process. The optimization is conducted in two cases. In the first case, a single-objective optimization is carried out to maximize the overall exergy efficiency. In the second case, a multi-objective optimization is accomplished considering the net output power and refrigeration capacity as the objective functions.

The results in the first case reveals a maximum overall exergy efficiency of 17.12% for which the net output power is 57.03 kW and the refrigeration capacity is 91.25 kW. In the case of multi-objective optimization, the results obtained from Pareto frontier shows a net produced power of 52.19 kW and a refrigeration capacity of 120.4 kW. With these data an overall exergy efficiency of 16.46% is calculated. The amount of fresh water calculated in case two is slightly higher than that obtained in case one.

提出了一种新型的多代混合动力系统，并从热力学的角度对其进行了详细的分析。该系统使用共沸混合物作为工作流体，由动力和喷射器制冷循环以及基于加湿和除湿过程的脱盐系统组成。在优化过程之前，将执行参数研究以指定影响系统性能的决策变量。优化在两种情况下进行。在第一种情况下，将执行单目标优化以最大程度地提高总火用效率。在第二种情况下，将净输出功率和制冷量作为目标函数来完成多目标优化。

在第一种情况下的结果显示最大总火用效率为17.12％，其净输出功率为57.03 kW，制冷能力为91.25 kW。在多目标优化的情况下，从帕累托前沿获得的结果显示净发电功率为52.19 kW，制冷能力为120.4 kW。利用这些数据，计算出的总火用效率为16.46％。在第二种情况下计算出的淡水量比在第一种情况下获得的淡水量略高。
