摘　　要：蓄冷空调,可调节电力供需以实现能量高效合理利用。为保护臭氧层和有效抑制温室效应,基于环保和节能的考虑,蓄冷空调新工质-气体水合物的替代选择被提上日程。为寻找新型水合物蓄冷工质,列出了理想蓄冷工质的特点,根据该选择要求,将可供选择的工质分为烷烃类、HFC类、可溶水类和混合类等几类作了详细介绍,列出了部分较有前景的工质,并对其应用作了展望,指出了今后的研究重点。More attention has been paid to the selection of new cool-storage media-gas hydrate in thermal storage air conditioning for environmental protection and energy saving. In this paper, the characteristics of ideal gas hydrate cool storage media are analyzed and the selection criteria are presented. The possible media are stated including alkane series, Hydro Fluorocarbons （abbre. HFCs）, water-soluble materials and binary mixtures. Some of these media with application prospect are described. In addition, the suggestion for further researech is presented.
