“…Gholizadeh et al 91 integrated a geothermal cycle, an ECC, and a humidification‐dehumidification unit for the simultaneous production of power, cooling, and desalination. The authors found that at an inlet turbine temperature of 143.8°C, the system produced 145.3 kW of power, 2176.3 kW of cooling load, and 1.52 kg/s of desalinated water.…”

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.

“…The rising energy demands and concerns about environmental pollutions have motivated the engineers to utilize new sources of energy such as solar, wind, and biogas [1][2][3][4]. The optimization of thermal systems is inevitable to increase the efficiency and reduce the cost and air pollution [2,[5][6][7][8][9].…”

“…Geothermal power plants are power generation systems that use geothermal fluids formed in the depths of the earth and are not directly affected by meteorological conditions in the way that solar, wind and hydropower systems are, thus differing them from other power plants that use renewable sources. Based on the temperatures and characteristics of geothermal reservoirs, geothermal fluids can also be used for different purposes such as space heating and cooling [ 1 , 2 ], combined heat and power (CHP) technology and even cooling through trigeneration along with power generation [3] , [4] , [5] , [6] industrial and agricultural drying, balneology, cosmetics or mineral recovery, which are classified as the direct applications aside from power generation.…”

Effective geothermal power generation depends on two main elements: geothermal reservoir management and maintenance of the power plant. Reservoir management consists of both the fluid production and reinjection of brine to the underground. The management of wells is important to ensure the sustainability of the reservoir. Thus, the flow rate control systems are essential to protect geothermal reservoirs under long-term power production. The second issue is the daily change in electricity prices and the load change process is complex because geothermal well controls are not flexible operations. The well management thus requires control approaches, and fuzzy control can be one effective solution. In this study, a fuzzy control system has been developed to control flow rates of the wells in Kızıldere geothermal field and its performance has been compared with the real data taken from the Kızıldere Power Plant. The results of comparison show that the fuzzy controllers achieved the target energy production in 2 h instead of 5 h, compared to the real data. Based on the real data, the reinjection was only able to stabilize at the end of the fourth hour and the process took only 2 h when using the fuzzy controllers.
