The technology of a hybrid solar concentration photovoltaic/thermal (CPV/T) system is an efficient way of converting solar energy to heat and electrical power, in which overall energy-extraction efficiency is at its highest. In this study, numerical dynamic simulation models were developed for a hybrid solar CPV/T system and an adsorption refrigeration system (ARS). Under the climatic conditions of Riyadh all year round, the electrical and thermal powers generated by the CPV/T system were used to estimate the ice production of both the vapor compression refrigeration system (VCS) and the ARS. The CPV/T system can provide a thermal energy of 37.6 kWh and electrical energy of 24.7 kWh a day on average over the year using a 12.5 m2 facing area of Fresnel lenses. The ARS employed an advanced approach which used Maxsorb III adsorbent packed in two aluminum foam beds. An optimum cycle time of the ARS was adapted for each month to match the variation in the thermal energy, while a variable-speed compressor was chosen for the VCS. Due to its higher coefficient of performance (COP), the proposed solar hybrid system can produce 494.4 kg of ice per day while sharing 84.5% of the VCS. The average solar COP over the year of the hybrid system can attain 0.875, which represents a promising value for a solar ice-production system.

“…To balance computational time and solution accuracy, 6.44 × 10 5 elements was chosen with relatively little error. The focal spot under outdoor conditions has been compared to other theoretical studies for a 10 mm 2 solar cell with no heat sink under a geometric concentration ratio of 500 suns, Aldossary et al [3] assumes uniform illumination as is standard within the literature, Alamri et al [7] use COMSOL's Ray Optics physics package. As is seen in Fig.…”

“…Besides having several advantages, a major advantage of ORC is that the system can be applied at a small scale compared to the water/steam RC systems [7]. Different energy sources like biomass, geothermal, and industrial waste heat other than solar energy can also be integrated with the ORC system for power generation [8][9][10][11][12][13][14][15]. For future sustainable energy systems, utilization of the organic fluid for the energy extraction from the exhaust heat from different energy sources is a viable option for the waste heat recovery system.…”

The energy consumption has gradually increased in the current context. Fossil fuels are the primary source of energy for the world’s population. Furthermore, energy derived from fossil fuels has significant disadvantages, including increased pollution and global warming. Solar energy is the fastest-growing alternative to fossil fuels among the various energy options. As a result, the focus of the present work is on the thermo-economic analysis of a hybrid solar-assisted intercooled gas turbine (GT) and organic Rankine cycle (ORC) for waste heat recovery and power production at near-zero-emissions. The work outcome and maximum efficiency of the hybrid arrangement are 1342.12 kW and 71.12% respectively at the cycle pressure ratio of 8, and 443 K entry point turbine temperature. The economic model of the integrated system depicts that the unit power production cost for the combined system has been evaluated as 1932 e per kW.
