对亨托夫工厂作为第一个商业化的压缩空气储能系统进行了参数研究，以突出支持明确的工程程序的优势和劣势。代替工厂特性的详细数据，现场特定的技术信息已通过四次模拟进行收集、分析和补充，这些模拟整合了工厂性能增强方法的效果，例如再生、冷却、热/冷水注入、蒸汽注入、热泵热回收和透平膨胀机能量回收。首先，考虑到排气中可避免的不可逆性，采用涡轮膨胀机进行回收和调节阀更换，以补偿设备的不可逆性。其次，还研究了配备蒸发冷却的蒸汽压缩制冷的效果，并评估了五种制冷剂，以减少压缩功。在第三次模拟中，研究了冷热水注入的利用效果。结果表明，通过蒸发和湿压缩两种冷却机制注水可提高工厂的往返效率。最后，在蒸汽注入研究中，通过采用新型超高温热泵提供所需的热源。对新型组合解决方案的评估表明，再生、压缩冷却、注水和蒸汽将工厂往返效率分别提高了 37.81%、3.22%、2.5% 和 2.78%。
A parametric study of Huntorf Plant as the first commercialized Compressed Air Energy Storage has been undertaken to highlight the strength and weaknesses in support of a well-defined engineering procedure. In lieu of detailed data on plant characteristics, the site specific technical information has been collected, analyzed, and complemented by four simulations that integrate the effects of plant performance-enhancing methods such as regeneration, cooling, hot/cold water injection, steam injection, heat recovery by heat pump and energy recovery by turbo-expander. Firstly, given the avoidable irreversibilities at the exhaust, recuperation and regulating valve replacement with a turbo-expander was established to compensate plant irreversibilities. Secondly, the effects of a vapor compression refrigeration equipped with evaporative cooling were also studied, along with assessing five refrigerants, to decrease the compression work. In the third simulation, the effect of utilization of the hot and cold water injection was investigated. It was shown that water injection by two cooling mechanisms such as evaporation and wet-compression enhances plant Round Trip Efficiency. Finally, in steam injection investigation, the required heat source was provided by employing a novel very high-temperature heat pump. The evaluation of novel combined solutions revealed that the regeneration, compression cooling, water and steam injection improve plant round trip efficiency by 37.81%, 3.22%, 2.5% and 2.78% respectively.
