To reduce energy consumption in temperature- and humidity-independent air-conditioning systems and enhance solar energy utilization, this study developed a solar-assisted desiccant wheel and adsorption cooling system (SDCS-A) using TRNSYS 18. System performance under Guangzhou's climatic conditions was analyzed by varying collector areas and tank volumes together with evaluating metrics such as system coefficient of performance (COPsys), solar fraction (Fs), and primary energy consumption (Ep). These results were compared with those of a solar-assisted desiccant wheel and vapor compression cooling system (SDCS-C). Findings indicate that changes in collector area significantly influence Fs and Ep, with Fs increasing by an average of 12.18%, while variations in tank volume predominantly affect COPsys, with a maximum difference of 0.1. Compared to SDCS-C, SDCS-A achieved 6.51% higher monthly average COPsys, a 21.05% increase in Fs, and a 21.45% reduction in Ep during the cooling season. Furthermore, the system's performance across different climates was evaluated, demonstrating that Guangzhou offers more stable and higher monthly COPsys values than Beijing, Shanghai, and Lhasa.
