Performance Assessment of a Novel Absorption Cooled Trigeneration System Powered by Solar Energy for Air Conditioning

utilizing the waste heat from the solar power tower (SPT) to run a basic helium Brayton cycle (HBC) is the aim of this study. The two subsystems that have been put in place to recover waste heat are the vapour absorption cooling system (VACS) and the heat recovery steam generator (HRSG), which is used for cooling air conditioning systems and heating to produce steam, respectively. A comprehensive exergy and energy analysis of this proposed trigeneration system were carried out with parametric analysis. For analysis purpose Engineering Equation Solver software has been used. It was concluded that energy and exergy efficiency and net work output of the proposed trigeneration system were observed as 44.96%, 34.15%, 14562 kW respectively. The heating production through the HRSG was obtained 8510 kW while the cooling production by VACS as 115.10 kW. Furthermore, the VACS subsystem's coefficient of performance (COP) was discovered to be 0.8015. Energy and exergy efficiency of the SPT operated basic HBC using the subsystems were improved by 58.98% and 12.92% respectively. Parametric analysis revealed that the helium turbine inlet temperature and solar heliostat field efficiency much affected the trigeneration system performance.
