Summary A comprehensive review of thermodynamic cycles for the simultaneous production of power and cooling is presented. The study not only actualizes the bibliographic reviews previously realized by other authors regarding cycles such as Kalina, Goswami, or modifications of them. This review additionally includes an overview of hybrid cycles and other novel cycles reported in the literature. The hybrid cycles included in the study are systems integrated by two or three conventional cycles, mainly composed of Brayton, Rankine, and ORC for power generation; and compression, absorption, and ejector cycles for cooling production. The other novel cycles mentioned are thermodynamic cycles, which considerably differ from all the others. By using internal rectification, the Goswami cycle increased its efficiency by about 5%; however, by adding diverse components, as a condenser and a subcooler, the efficiency was significantly improved due to the considerable increase of the cooling production. Organic Rankine cycles integrating absorption refrigeration cycles are, in general, the most efficient hybrid cycles, reaching thermal efficiencies close to 40% for the simultaneous production of power and cooling. If a third output was provided, as heating or water distillation, the energy efficiencies were as high as 90%. The main problem with these systems is that, in general, they are too complex and costly because of the considerable number of components. The highest exergy destruction values are reported in solar collectors when used, followed by boilers or generators, and absorbers. The lower production costs were reported with systems integrating a Brayton cycle, an organic Rankine cycle, and an ejector‐cooling cycle. The disadvantage of these systems is that they need high operating temperatures.

Combined systems for power production and thermally activated cooling have a high potential for improving the efficiency and utilisation of thermal systems. In this regard, various configurations have been proposed and are comprehensively reviewed. They are primarily based on absorption systems and the implementation of multiple levels of complexity and flexibility. The configuration of the absorption power and cooling combined cycle proposed herein has wide commercial applicability owing to its simplicity. The configuration of the components is not new. However, the utilisation of aqueous salt solutions, the comparison with ammonia chiller and with absorption power cycles, the focus on parameters that are important for real-life applications, and the comparison of the performances for constant heat input and waste heat recovery are novel. The proposed cycle is also compared with a system based on the organic Rankine cycle and vapour compression cycle. An investigation of its performance proves that the system is suitable for a given range of boundary conditions from a thermodynamic standpoint, as well as in terms of system complexity and technical feasibility. New possibilities with regard to added power production have the potential to improve the economics and promote the use of absorption chiller systems.

In this article the solar energy is utilized to generate needed steam for a power generation cycle which in turn provides the required power of a RO system. Optimization was carried out on two levels. First, Economizer, Evaporator, Super heater in power generation cycle as well as the type of membrane, PV numbers and series were optimized. In addition, the optimum design of a solar field for the system was carried out and the collector specifications, number of branches, and flow rate were designed. Based on the first level, optimization was designed to reduce costs and increase the permeate water production and reduction in costs and pressure drop of the solar filed. Preheating of the RO feed water had different effects on the production of fresh water at various concentrations. For feed water with constant flow rate and concentration of 45 000 ppm, the maximum rate of permeate flow was obtained at 26°C, while for concentration of 35 000 ppm, the maximum permeate flow rate was achieved at 33°C. By using 5 parallel elements SW30XLE‐400 for RO system, in the optimized condition, permeate flow rate and recovery were 9494.19 (m3/day) and 59.5%, respectively. In this condition, the unit production cost of water was 0.6046 ($/m3).
