Abstract: In order to solve the problem of refrigerant hydrate formation in a static state ，the Tergitol TMN－6 as emulgator，R141b emulsions were prepared with speed stirring and supersonic respectively，then formed hydrate and decomposed under the condition of program control temperature．The results show that O／W R141b emulsion can be formed with both of the two methods．The two emulsions，at static state，can begin to be formed hydrate within 1.5 h after start of air bath，and finish in 2 h．It is easy for decomposition liquid to be emulsified and to be formed hydrate again．With this method，it can be performed in several hours for a study on hydration mechanism，which provides academic foundation for the application of refrigerant hydrate to cold accumulation air－conditioner．

摘要： 为解决静态下制冷剂水合物难于形成的问题，以表面活性剂Tergitol TMN-6作为乳化剂、分别采用高速搅拌和超声波两种方式制备R141b乳状液，随后在控温箱中使R141b乳状液形成气体水合物，并使该气体水合物分解。实验结果表明，应用以上两种能量方式都可以制备出稳定的O/W型 R141b乳状液。在静态下，以上两种方式制备的乳状液均可以于空气浴启动后1 .5 h之内开始形成气体水合物，并于2 h内完成水合反应；水合物分解液易于重新乳化并形成新的水合物。本实验使制冷剂水合物形成的机理研究能在数小时内完成，并为制冷剂水合物应用于蓄冷空调提供理论依据。
