The invention provides a mixed refrigerant and an air conditioning system. The mixed refrigerant comprises a first component, a second component and a third component, the first component is ammonia,the second component is difluoromethane, and the third component is trans-1-chloro-3, 3, 3-trifluoropropene or 1, 1, 1-trifluoroethane. The mixed refrigerant provided by the invention has low GWP andgood thermal performance, the GWP value of the mixed refrigerant can be lower than 150, the COP energy of the mixed refrigerant is much higher than that of R134a, the volume refrigerating capacity ofthe mixed refrigerant is much higher than that of R134a, the problem that other refrigerants replacing R134a are high in GWP is effectively solved, and meanwhile the problem that other refrigerants are poor in thermal performance is solved. The sliding temperature of the mixed working medium can be lower than 0.5 DEG C, adverse effects caused by temperature sliding are eliminated, and potential safety hazards caused by combustible refrigerants can be reduced or even eliminated through the secondary circuit automobile air conditioning system.
本发明提供一种混合制冷剂和空调系统,所述混合制冷剂包括第一组分、第二组分和第三组分,其中:所述第一组分为氨,所述第二组分为二氟甲烷,所述第三组分为反式‑1‑氯‑3,3,3‑三氟丙烯或者1,1,1‑三氟乙烷。本发明的混合制冷剂具有低GWP及良好的热力性能,GWP值能够达到低于150,混合制冷剂的COP能比R134a高很多,容积制冷量能够比R134a高很多,有效解决了其他替代R134a制冷剂的GWP偏高的问题,同时还解决了其他制冷剂的热力性能差的问题。而且可以使得混合工质的滑移温度小于0.5℃,排除温度滑移带来的不良影响,其中二次回路汽车空调系统可以减小甚至消除可燃制冷剂带来的安全隐患。
