摘要
简单介绍了LNG冷能和压缩空气储能耦合模型。为了提高该耦合系统的冷能利用效率,提出了系统热效率η1余热利用效率η2,以便能够更加综合准确地评价系统性能。根据热力学原理,在Aspen plus中选取PSRK方程,模拟并分析了随着系统模型中压力和温度等关键参数的变化,两个效率的变化机理。
A brief introduction of LNG cold energy generation and compressed air energy storage coupled model.In order to improve the cooling efficiency,there are two new efficiency have been proposed:thermal efficiency η1 and waste heat utilization efficiency η2,to accurate comprehensive and integrated evaluation of system performance.According to the principles of thermodynamics,select SRK equation in Aspen plus,analyzing and imitating and interpreting the two efficiency changes,accompanied by changes of two key parameters:pressure,temperature in model.
