This study theoretically investigates the energetic and economic feasibility of three configurations of a solar-driven hybrid adsorption-compression cooling system using typical meteorological data of Cairo, Egypt. In Configuration-I, adsorption system is driven by solar collectors and vapor compression system is electrically powered. In Configuration-II, supplementary photovoltaic panels are used to power the vapor compression cycle, resulting in a net-zero electricity consumption scheme. For prolonged operation, Configuration-III is presented with an additional cold storage tank between adsorption and compression subsystems. Silica/gel water is utilized as a working pair in the adsorption cycle, while R410A is employed for the vapor compression system. Mathematical modeling is formulated using the MATLAB/Simulink platform and validated against experimental data from the most relevant literature. For Configuration-I, theoretical results demonstrate that the electricity consumption reduces in June from 22.37 kWh to 5.9 kWh by increasing the size ratio between the adsorption and the compression systems from 0.867 to 1.333. Configuration-I can substantially alleviate the electricity consumption by 62.5% compared to the conventional vapor compression system. It is also found that Configuration-II can save electrical energy consumption as high as 2897 kWh/year. Although Configuration-III experiences annual energy savings of 47% compared with Configuration-I that achieves 64%, it operates for prolonged durations as a redeeming feature. Moreover, economic analysis is conducted for the three examined configurations, revealing that Configuration-II is economically viable with a payback period of 9.65 years. These findings could spur designers and stakeholders into utilizing new hybrid cooling systems in preference to the predominant compression cooling systems.

这项研究使用埃及开罗的典型气象数据，从理论上研究了太阳能驱动的混合吸附-压缩冷却系统的三种配置的能源和经济可行性。在配置I中，吸附系统由太阳能收集器驱动，而蒸气压缩系统由电动驱动。在配置II中，辅助光伏面板用于为蒸汽压缩循环提供动力，从而实现了净零电耗方案。为了延长运行时间，配置III在吸附和压缩子系统之间提供了一个额外的冷库。硅胶/凝胶水在吸附循环中用作工作对，而R410A用于蒸汽压缩系统。数学建模是使用MATLAB / Simulink平台制定的，并根据最相关文献中的实验数据进行了验证。对于配置I，理论结果表明，通过将吸附和压缩系统之间的尺寸比从0.867增加到1.333，6月的电力消耗从22.37 kWh减少到5.9 kWh。与传统的蒸气压缩系统相比，配置I可以实质上将电力消耗减少62.5％。还发现，配置II可以节省高达2897 kWh /年的电能消耗。尽管Configuration-III的年度节能量达到了64％，而Configuration-I却实现了47％的节能率，但作为赎回功能，其运行时间却更长。而且，对三个已检查的配置进行了经济分析，结果表明，配置II在经济上可行，投资回收期为9.65年。这些发现可能会促使设计人员和利益相关者优先于主要的压缩冷却系统而使用新的混合冷却系统。
