摘　　要：压缩空气蓄冷系统是一种新型的冷量储存系统。针对这种系统,本文研究了四种不同的循环实现形式。分析了这四种循环形式的制冷量、运行性能系数COP并对其进行了对比。结果表明:压缩空气蓄冷系统应用于室温条件下的制冷场合时,两级压缩、三级膨胀驱动蒸气压缩制冷系统相对于其他三种循环,运行性能较好;两级压缩、三级膨胀驱动空气压缩膨胀制冷循环,可以制取的制冷温度较广,适应变工况的能力较好,并且结构简单,也具有一定的优势。Compressed air cool storage system is a new way for energy storage. Four different refrigeration cycles based on this system were studied. Refrigeration capacity and coefficient of performance of each cycle were analyzed and compared. The analysis results indicate that the performance of the cycle with double compression/thrice expansion air system by which a vapor compression refrigeration sub-system is driven is the best one among four other cycles under room temperature refrigeration condition. But the cycle with double compression/thrice expansion air system by which an air refrigeration sub-system is driven has other advantages, such as being able to work in a great temperature range, simple in structure, etc.
