Abstract

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 (COP

sys

)

solar fraction (

)

and primary energy consumption (

). 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

and

with

increasing by an average of 12.18%

while variations in tank volume predominantly affect COP

sys

with a maximum difference of 0.1. Compared to SDCS-C

SDCS-A achieved 6.51% higher monthly average COP

sys

a 21.05% increase in

and a 21.45% reduction in

during the cooling season. Furthermore

the system's performance across different climates was evaluated

demonstrating that Guangzhou offers more stable and higher monthly COP

sys

values than Beijing

Shanghai

and Lhasa.
