Hybrid vapor compression systems based on adsorption are recognized as a viable alternative to traditional energy-intensive compression systems. Solar-powered hybrid adsorption-compression refrigeration systems feature a solar-powered silica gel/water-based adsorption cooling system paired with a traditional compression system that utilizes R134a as a refrigerant. Herein, the system feasibility of a solar-operated hybrid adsorption-compression refrigeration system has been evaluated theoretically using typical climatic data of Alexandria, Egypt. Mathematical modeling is generated and compared to the most relevant experimental data. PVT collectors are exploited to drive both the adsorption and the compression units. Simulation results suggest that using a three-to-one system size ratio between the adsorption and compression subsystems might considerably raise the COP from 2.9 to 5 for the compression system. It is observed that at an ideal size ratio of 7, the proposed system can considerably deliver an energy saving of 30.8 percent, compared to the hybrid system of the size ratio of 3, which attains only energy savings of 22.1 percent. Furthermore, the utilization of PVT collectors might feed the hybrid system by 3.474 kWh and augment the electric grid by 100 kWh, at an ideal size ratio of 7. Overall, investigating hybrid adsorption-compression systems might offer unique insight on optimizing the performance of conventional counterparts.

Summary In this study, theoretical performance investigation and economic analysis of hybrid solar system‐driven integrated reverse osmosis (RO)/adsorption multigeneration system have been performed. The system delivers the required cooling during summer operation via adsorption chiller freshwater and electricity via RO unit and photovoltaic/thermal (PVT) collectors, respectively, throughout the year for building in Alexandria, Egypt during the typical daily working hours. A hybrid solar system comprising evacuated tube collectors (ET) and PVT collectors is proposed to supply the required heat and electricity. Four configurations: Case 1 has only PVT, Case 2 has 75% PVT and 25% ET, Case 3 has 50% PVT and 50% ET, and Case 4 has 25% PVT and 75% ET. A dynamic model for the performance of the proposed multigeneration system is constructed and analyzed using MATLAB software. The results show that increasing PVT area share improves system energy and exergy efficiencies and economic performance but at the expense of produced cooling capacity. The average cooling of the adsorption chiller is 5.8, 7.6, 9.5, and 11.5 kW for Cases 1 to 4, respectively, and RO specific energy consumption is about 2.467 kWh/m3 of freshwater. Energy savings of approximately 32.95 MWh/year are achieved for Case 1, while its CO2 emissions cut is about 18.06 of equivalent tonCO2 per year. The Payback periods of the proposed system are about 10.3, 11.68, 15.85, and 24.3 years for Case 1 to Case 4, respectively, demonstrating the system economic viability.
