Abstract In this paper, the performances of four combined power and cooling systems are compared in which the exhaust heat of a topping gas turbine plant is utilized for further power and cooling generation. Steam turbines (STs) and organic Rankine cycles (ORCs) are used for power generation by integrating those in a completely different arrangement in the first two systems while the third and fourth systems use ST based power cycles. The first and the fourth configuration uses two absorption cooling systems (ACSs) driven respectively by steam and exhaust heat. In the second and third systems, however, only one ACS is used. Energy and exergy based parametric analyses are done, showing the performance variations with HRSG steam pressure from 89 to 94 bar for comparing the CPC systems. The fourth system was found to be the most appropriate from the energetic and exergetic performance viewpoint with the first system to follow. Despite an additional ACS, the total irreversibility of the first and the fourth systems was found almost equivalent to that of the second system. Only in the third system, the total plant irreversibility was relatively less compared to the first and the fourth. It was found that the GT plant alone contributes more than 95% irreversibility in all the four systems.

四种不同的动力和冷却联合系统与顶部燃气轮机装置集成的比较性能分析

摘要 在本文中，比较了四种动力和冷却联合系统的性能，其中利用顶部燃气轮机装置的废热进一步发电和冷却。蒸汽轮机 (ST) 和有机朗肯循环 (ORC) 通过在前两个系统中以完全不同的布置集成它们来发电，而第三和第四个系统则使用基于 ST 的动力循环。第一种和第四种配置使用两个吸收式冷却系统 (ACS)，分别由蒸汽和废热驱动。然而，在第二和第三系统中，仅使用一个ACS。完成了基于能量和火用能的参数分析，显示了 HRSG 蒸汽压力从 89 到 94 bar 的性能变化，以比较 CPC 系统。从精力充沛和精力充沛的表现角度来看，第四个系统被认为是最合适的，第一个系统紧随其后。尽管增加了 ACS，但发现第一个和第四个系统的总不可逆性几乎与第二个系统相同。只有在第三个系统中，与第一个和第四个系统相比，总的植物不可逆性相对较小。结果表明，在所有四个系统中，仅 GT 装置就造成了超过 95% 的不可逆性。
