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 (F_s), and primary energy consumption (E_p). 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 F_s and E_p, with F_s 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 F_s, and a 21.45% reduction in E_p 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.

By virtue of its long lifespan and outstanding storage intensity with near-zero heat loss, salt hydrate thermochemical energy storage (TES) materials provide a feasible option for the effective use of renewable energy and overcoming its unsynchronized supply and demand. Here, an activated porous carbon originating from the zeolite imidazolate framework (ZHCM) is fabricated and served as the carbon matrix for the LiOH TES material. The as-synthesized Li/ZHCM2-40 not only has excellent storage intensity (maximum 2414.2 kJ·kg⁻¹) with low charging temperature, but also shows great hydration properties stemming from the ultrahigh surface area and hierarchical porous structure of ZHCM2. Besides, this composite material exhibits superior thermal conductivity, while its storage intensity is only attenuated by 10.2% after 15 times of consecutive charge–discharge process, revealing its outstanding cycle stability. And the numerical simulation results also demonstrate its superior heat transfer performance. The developed LiOH TES composite may afford a new avenue for efficient low-grade thermochemical energy storage and liberate the possibility of further exploration of metal organic frameworks derived porous carbon matrix in the future.
