Abstract
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.
