LNG气化冷能利用虽然在全球受到普遍重视，但大多数国家尚在发展之中，且开发的利用技术多数针对大型气化站。小型气化站可提供的冷能虽少，但冷能的品位较高，应用于建设冷冻仓库是颇为经济有效的利用途径；广东佛山杏坛冷库为国内首个小型气化站LNG冷能利用示范性项目，其成功经验值得重视。LNG冷能应用汽车空调系统及低温冷藏车可以最大程度地回收气化过程中产生的冷能，并减少汽车的尾气排放；此类应用目前虽尚未实现工业化，但国内外此方面的研究正方兴未艾，值得重视。

Although the problem of cold energy utilization of LNG regasification has aroused global attention ,most of these techniques are still in their early stages and only for large plants . Satellite plants can only supply small amount of cold energy ,but its quality is very good .It is an economical and effective way to utilize this energy for building cold storage .The first demonstra-tion project of China is the Xingtan Cold Storage built in Foshan City of Guangdong Province and its successful experience is worthy of attention .If the energy is used for car air conditioning sys-tem and refrigerated vehicles ,the cold energy would be recovered at a maximum extent and ex-haust emission can be reduced at the same time .Even new techniques mentioned above are not commercialized at present ,their advances are ascendant at home and abroad .
