The operation of solar driven air conditioning systems is limited to the availability of solar radiation. Consequently, to achieve extended cooling period, energy storage is necessary. This study presents performance evaluation and charging and discharging characteristics of an absorption energy storage coupled with solar driven double-effect water-lithium bromide (H₂O-LiBr) absorption system through thermodynamic modeling and simulation. The absorption energy storage stores the solar heat in the form of chemical energy during the day and discharges later for cooling application. The integrated system achieved effective cooling for about fourteen hours on daily basis. The results indicate an average coefficient of performance (COP) of 1.35 for the integrated absorption chiller-storage unit and exergy efficiency of 25%. Furthermore, the overall COP of the integrated solar cooling system is 0.99 and the overall exergy efficiency is 6.8%, while the energy storage density for typical climatic conditions of Dhahran, Saudi Arabia is found to be 444.3 MJ/m³. The energy storage density obtained from the integrated solar driven H₂O-LiBr double-effect absorption system is found to be higher by 13–54% compared to other integrated systems based on single-effect configuration.

太阳能驱动的空调系统的运行受限于太阳辐射的可用性。因此，为了延长冷却时间，必须存储能量。这项研究提出了结合太阳能驱动的双效水-溴化锂（H _2）的吸收储能器的性能评估和充放电特性O-LiBr）吸收系统通过热力学建模和仿真。吸收式能量储存器白天以化学能的形式存储太阳热，稍后排放以进行冷却。该集成系统每天有效冷却约14个小时。结果表明，集成式吸收式冷水机组的平均性能系数（COP）为1.35，火用效率为25％。此外，集成太阳能冷却系统的总COP为0.99，总火用效率为6.8％，而沙特阿拉伯达兰的典型气候条件下的储能密度为444.3 MJ / m ³。由集成太阳能驱动的H ₂获得的储能密度发现O-LiBr双效吸收系统比其他基于单效配置的集成系统要高13–54％。
