In order to increase the performance and power output of the conventional combined cycle power plant (CCPP), a CCPP-AdCS (adsorption cooling system) with a maximum cooling capacity of 6000 kW is proposed in the present study. A model for CCPP simulation is developed, and it is validated through practical data. The thermal performance and economic analysis of the proposed CCPP-AdCS are evaluated. The results reveal that the CCPP-AdCS has the largest desorption and cooling capacity when the desorption temperature is 60 °C, and the maximum cooling degree of the inlet air is 8.73 °C. Compared to the CCPP, the power output can be significantly improved by the CCPP-AdCS. The maximum power output augmentation is 22.72 MW in July when the desorption temperature is 60 °C. By comparing to the existing literature, the CCPP-AdCS shows higher energy efficiency increment than CCPPs that integrated with absorption cooling system or mechanical cooling system. The payback time (PBT) of the CCPP-AdCS is only 2.34 years when the CCPP-AdCS is operated at a desorption temperature of 60 °C.

为了提高传统联合循环发电厂 (CCPP) 的性能和功率输出，本研究提出了最大冷却能力为 6000 kW 的 CCPP-AdCS（吸附冷却系统）。开发了 CCPP 仿真模型，并通过实际数据对其进行了验证。对提议的 CCPP-AdCS 的热性能和经济分析进行了评估。结果表明，CCPP-AdCS在解吸温度为60℃时具有最大的解吸和冷却能力，入口空气的最大冷却度为8.73℃。与 CCPP 相比，CCPP-AdCS 可以显着提高功率输出。当解吸温度为 60°C 时，7 月份的最大功率输出增幅为 22.72 MW。与现有文献相比，CCPP-AdCS 比集成吸收式冷却系统或机械冷却系统的 CCPP 显示出更高的能效增量。当 CCPP-AdCS 在 60 °C 的解吸温度下运行时，CCPP-AdCS 的投资回收期 (PBT) 仅为 2.34 年。
