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。
