中文摘要：

压缩空气蓄能系统（compressed air energy storage，CAES）是一种新型的蓄能系统，利用储存的高压空气的膨胀功和膨胀后的低温空气进行制冷。常规的空气制冷系统在制取-50～-100℃的制冷温度时具有较好的经济性能，本文提出将这种常规的空气制冷系统与压缩空气蓄能系统相结合形成一种新型低温制冷系统。文章讨论了此种低温制冷系统的组成形式和运行方式，并计算其运行性能，且与常规的空气制冷系统和蒸气压缩制冷系统进行了对比。结果显示该新型低温制冷系统在-50～-100℃制冷温度时，性能优于常规系统。

英文摘要：

Compressed air cool storage system （CAES） is a new way to save energy, which utilizes the expansion work of stored compressed air and the resulting low temperature air to get the purpose of refrigeration. The regular air cool system is of well economic ability at -50～-100℃ refrigeration condition. Based on the conventional one, a novel low-temperature refrigeration cycle was developed. This article discussed the component and function mode, and computed the circulating performance. Besides, the new air refrigeration cycle is compared with the routine system and the vapor compression one. The results indicate that the fresh method excels the common cooling process under the refrigeration condition of -50～-100℃.
