“…For instance, the generation of coolant gas from the adsorption bed can be achieved by utilizing a heating source with a temperature of 50 • C, particularly when employing silica gel as an adsorption medium with water as the coolant fluid [9]. The aforementioned statement highlights the appeal of researching solar-powered adsorptionbased cold-generating devices [10]. Within the realm of the scholarly literature, numerous investigations have been undertaken to explore, enhance, and modify these systems with experimental, theoretical, or combined approaches [11][12][13][14][15].…”

In a previous work, a solar chimney power plant integrated with a solid sorption cooling system for power and cold cogeneration was developed. This prior work showed that reusing the heat released from the adsorption bed enhances the system’s utilization of solar energy and increases the turbine’s output power. In the present paper, a subsequent modification to the arrangement and operation of the preceding system is introduced. The primary objective of the modification is to enhance performance and increase the plant’s capacity to effectively harness the available solar radiation. The method involves placing the condenser tubes at the solar collector entrance. Therefore, the airflow captures the condenser-released heat before it enters the collector. The modified configuration and operation of the system are discussed. A dynamic mathematical model is established to simulate the hybrid system’s operation and evaluate its parameters. The obtained results show that a 5.95% increase in output power can be achieved by recovering the heat of condensation. Furthermore, the modified system attains a 6% increase in solar-to-electricity conversion efficiency compared with the basic system. The findings suggest that the modified system, which recycles condenser heat, provides noticeable enhanced performance compared with the basic system.
