由于压缩空气蓄能(CAES)是一种很有前途的储能技术，已经在商业运行中证明了它的可靠性，因此本文对该过程的一些基本热力学信息进行了阐述。它显示了亨托夫和麦金托什CAES电厂的热力学过程循环的比较，并已在EES(工程方程求解器)中进行了建模。文中给出了详细的T-S图，说明了CAES可逆和不可逆热力学模型的区别。结果表明，不可逆性假设导致了对电厂效率的过高估计，因此不应将较新的CAES概念(如绝热CAES)近似为可逆性假设，以避免误导性陈述。
As compressed air energy storage (CAES) is a promising energy storage technology that has already proven its reliability in commercial operation some basic thermodynamic information on this process are elaborated in this paper. It shows a comparison of the thermodynamic process cycles of the CAES plants in Huntorf and McIntosh that has been modeled in EES (Engineering Equation Solver). Detailed T-s-Diagrams are given to show the differences of reversible and irreversible thermodynamic modeling of CAES. It is demonstrated that irreversibility assumption leads to an over estimation of the plant efficiency and therefore newer CAES concepts (like adiabatic CAES) should not be approximated with reversibility assumptions to avoid misleading statements.
