本公开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、第三组分和第四组分,其中:所述第一组分为氟乙烷,所述第二组分为3,3,3‑三氟丙烯和2,3,3,3‑四氟丙烯中的一种,所述第三组分为1,1,2‑三氟乙烯,所述第四组分为为三氟碘甲烷。本公开混合制冷剂可以作为R134a的替代制冷剂,其GWP小于4,ODP为0,具备明显的环保优势,同时该环保混合制冷剂热力性能与R134a相当甚至更高,因此在能够保证制冷剂热力性能与R134a相当甚至更好的同时,还能有效解决R134a制冷剂高GWP值的技术问题。

    The invention provides a mixed refrigerant and an air conditioning system. The mixed refrigerant comprises a first component, a second component, a third component and a fourth component, wherein the first component is fluoroethane, the second component is one of 3, 3, 3-trifluoropropene and 2, 3, 3, 3-tetrafluoropropene, the third component is 1, 1, 2-trifluoroethylene, and the fourth component is trifluoroiodomethane. The mixed refrigerant can be used as a substitute refrigerant of R134a, the GWP of the mixed refrigerant is smaller than 4, the ODP of the mixed refrigerant is 0, the mixed refrigerant has the obvious environment-friendly advantage, meanwhile, the thermal performance of the environment-friendly mixed refrigerant is equivalent to or even higher than that of R134a, and therefore it can be guaranteed that the thermal performance of the refrigerant is equivalent to or even better than that of R134a, and meanwhile, the technical problem that the GWP value of the R134a refrigerant is high can be effectively solved.
