LNG 冷能在冷冻冷藏库中的应用

摘要

介绍了国内外 LNG 冷能应用于冷库中的发展现状。幵对 LNG 冷能在冷库中的单一利用和梯级利用两种应用形式迚行比较，最终得出采取梯级利用形式才能实现充分合理利用 LNG 冷能的结论。较之传统的冷库电压缩式制冷工艺，LNG 冷能用于冷库的制冷工艺可以大大节省耗电量，降低冷库运行成本，经济效益显著。%The development status of LNG cold energy used in cold storage at home and abroad was introduced. And two kinds of application forms including the single use and the cascade utilization of LNG cold energy in cold storage were compared, and it's pointed that the form of cascade utilization can achieve full and rational use of LNG cold energy. Compared with the traditional cold storage electric compression refrigeration process, LNG cold energy refrigeration process in cold storage can greatly save power, reduce the operation cost of cold storage.
