## 5 Conclusions  
The CPC is effective in providing the required temperature and heat to the SVAR generator during the peak cooling load. The performance and contribution of SVAR increase with time from 10 a.m. to 1p.m., decreasing the use of high-grade energy from VCR. The reason for the lower fluid outlet temperature of 63.5 \({}^{\circ}\)C is due to the higher value of U\({}_{\text{L}}\). The proposed model is effective in providing the required energy to SVAR for annual use.  
The energy and exergy of COP related to the vapor compression system is higher than in other hybrid cooling models because the former uses high-grade energy for its operation, which strongly agrees with the results of our preliminary research work. The configuration integrating VCR to the condenser of the SVAR has less effect on the performance of the hybrid system. The SVAR integrated in series with the VCR condenser system produces 83% higher COP than the system with VCR integrated with the condenser of the SVAR system. Similarly, they have 88% and 84% higher values of exergy COP and exergy efficiency respectively.  
From the analysis of solar hybrid cooling models as detailed in model 4, the integration of SVAR to the condenser of the VCR can be used as an alternative to the individual VCR system, which comes with high-grade energy. The higher exergy efficiency of 3.84 in model 4 also leads to the conclusion that the system is more sustainable and the exergy destruction is minimal.  
The integration of SVAR to the condenser of the VCR as a hybrid model increases the cooling capacity of the VCR by 68% and also increases the exergy efficiency by 51.6%, thus increasing the performance of the system and decreasing the exergy destruction. The integration of SVAR by utilizing the CPC to the condenser of the VCR as a hybrid model increases the cooling capacity of the VCR by 68% and decreases the carbon emission by 166.4%.  
Considering system performance, the temperature of the SVAR generator is limited to the concentration of the LiBr in the Libr-H\({}_{2}\)O mixture. The losses in the CPC are one of the important parameters to be considered, for the losses increase the CPC, and the system efficiency decreases.

In the future, a SVAR absorber and condenser could provide a low-grade, high quantity of energy for suitable applications such as drying. Analyzing the cost of the power from the proposed module and comparing the results to those of a photovoltaic module would demonstrate how quickly such a module would pay back. As the world is evolving toward AI, the integration of the proposed system could be an effective approach to increase the performance of the solar hybrid cooling system.
