摘要
压缩空气储能是一种极具潜力的大规模储能技术,传统的压缩空气储能技术存在储能密度低、储存容积大等缺点,应用推广受到很大限制。液态空气储能技术是一种新兴的压缩空气储能技术,相比于传统压缩空气储能技术,能量储存密度显著提高。因此,基于低温空气液化原理,提出一种液态空气储能系统,其核心热力学过程为将空气降温液化后以高压状态存储,通过节流后的空气实现冷量回收,使得系统不需引入额外冷量。对该系统进行热力学分析和参数优化,结果表明系统效率可达50%以上。
Compressed air energy storage （CAES） is one of the potential large -scale energy storage technologies. However, its application is restricted because of the disadvantage of low energy density and large storage volume. Liquid air energy storage （LAES） technology is a new CAES technology,which can improve the energy density obviously. So on the principle of air lique- faction,it described a liquid air energy storage system, the air was liquefied and stored with high pressure. Cold energy was recov- ered through throttled liquid air, so extra refrigeration process was unnecessary. Thermo dynamic analysis of the system perform- ance was also presented by simulation. The optimization results show that the efficiency of LAES system is up to 50%.
