The invention discloses a mixed refrigerant, a preparation method and application thereof and an automobile air conditioning system, relates to the technical field of air conditioners, and solves thetechnical problems of high GWP value and low COP of an R134a refrigerant in the prior art. The mixed refrigerant comprises a first component, a second component and a third component, the first component is propane, the second component is difluoromethane, and the third component is one of ammonia, fluoroethane and propylene. The mixed refrigerant provided by the invention has a low GWP value andhas COP superior to that of an R134a refrigerant. Specifically, the GWP value of the mixed refrigerant is lower than 150, and meet the requirements of environmental protection laws and regulations inall regions of the world, under proper proportion, the thermal performance is superior to that of an R134a refrigerant, the slippage temperature of the mixed refrigerant is lower than 1DEG C, and adverse effects caused by temperature slippage can be eliminated. The environment-friendly performance and the thermal performance of the mixed refrigerant are good and are superior to those of an R134a refrigerant.

    本发明公开了一种混合制冷剂及其制备方法和应用、汽车空调系统,涉及空调技术领域,解决了现有技术中R134a制冷剂GWP值较高、COP较低的技术问题。本发明的混合制冷剂,包括第一组分、第二组分和第三组分,其中,第一组分为丙烷,第二组分为二氟甲烷,第三组分为氨、氟乙烷和丙烯中的一种。本发明的混合制冷剂,在具有低GWP值的同时,具有优于R134a制冷剂的COP。具体的,本发明混合制冷剂的GWP值低于150,符合全球各地区的环保法规要求,在适当配比下,热力性能不仅优于R134a制冷剂,而且本发明混合制冷剂的滑移温度小于1℃,可排除温度滑移带来的不良影响。即本发明混合制冷剂的环保性能和热力性能好,优于R134a制冷剂。
