In recent decades, innovations in desalinating water and cooling have led to improving the living standards and well-being. The significance of these technologies provides a path for synergistic integration. In the present study, a novel combined ejector cooling with a humidification-dehumidification desalination system for cogeneration of a considerable amount of cooling and water was thoroughly studied in two configurations: solar-driven (system A) and waste heat-driven configurations (system B). The mathematical models were based on the first and second laws of thermodynamics and exergoeconomic relations to predict the performance and economic feasibility of the proposed systems. The studies were conducted under variation of the generator, condenser, and evaporator temperatures, and solar irradiance intensities. Many parameters were studied, including freshwater production, cooling capacity, COP, GOR, exergy destruction, and product costs. The freshwater and cooling costs for system A were 24.61 US$/m³ and 0.01544 US$/kWh, whereas, for system B, they were 3.84 US$/m³ and 0.001677 US$/kWh. However, the cost of the above products from system B can be as low as 2.39 US$/m³ and 0.001670 US$/kWh, respectively. It was concluded that the 24-hour operation and replacement of solar collectors with free waste heat recovery resulted in drastically reducing the cost of the products.

在最近的几十年中，对水和冷却系统进行脱盐处理的创新导致生活水平和福祉的改善。这些技术的重要性为协同集成提供了一条途径。在本研究中，以两种配置对太阳能驱动（系统A）和废热驱动配置（系统B）的新型组合喷射器冷却与加湿-除湿脱盐系统进行联用，以同时产生大量的冷却和水进行了彻底研究。 ）。该数学模型基于热力学第一定律和第二定律以及人类经济关系来预测所提出系统的性能和经济可行性。在发生器，冷凝器和蒸发器温度以及太阳辐照强度的变化下进行了研究。研究了许多参数 包括淡水生产，冷却能力，COP，GOR，火用破坏和产品成本。系统A的淡水和冷却成本为24.61美元/米³和0.01544美元/千瓦时，而对于系统B，它们分别为3.84美元/米³和0.001677美元/千瓦时。但是，来自系统B的上述产品的成本分别可以低至2.39美元/ m ³和0.001670美元/ kWh。可以得出结论，全天候24小时运行和免费回收废热可替代太阳能集热器，从而大大降低了产品成本。
