The invention relates to the technical field of refrigerants, in particular to an environment-friendly mixed refrigerant, a preparation method thereof and a refrigerating system. The environment-friendly mixed refrigerant comprises a first component and a second component, the first component is fluoromethane, and the second component is one or two of 2, 3, 3, 3-tetrafluoropropene and trans-1, 3, 3, 3-tetrafluoropropene. The environment-friendly mixed refrigerant comprises the following components in percentage by mole: 12-48% of a first component and 52-88% of a second component. All the components of the environment-friendly mixed refrigerant are mixed and stirred in a normal-temperature liquid-phase state, and the environment-friendly mixed refrigerant is obtained. The environment-friendly mixed refrigerant provided by the embodiment of the invention can better replace an R134a refrigerant, on one hand, the environment-friendly and safety characteristics of the refrigerant are considered at the same time, it is guaranteed that the safety level is not lower than A2L on the basis that GWP is smaller than 150, on the other hand, the high-temperature refrigeration performance and the low-temperature heating performance are guaranteed at the same time, the energy efficiency is basically equivalent to that of the R134a, and the volume refrigerating/heating capacity is improved by more than 10% and can be improved by 121% at most.

    本申请涉及制冷剂技术领域,具体而言,涉及一种环保混合制冷剂、该环保混合制冷剂的制备方法及制冷系统。环保混合制冷剂包括第一组分和第二组分,其中:第一组分为一氟甲烷,第二组分为2,3,3,3‑四氟丙烯和反式‑1,3,3,3‑四氟丙烯中的一种或两种。以摩尔百分比计,环保混合制冷剂包括12‑48%的第一组分和52%‑88%的第二组分。将环保混合制冷剂的各组分在常温液相状态下混合并搅拌,得到环保混合制冷剂。本发明实施例提出的环保混合制冷剂能够较好的对R134a制冷剂进行替代,一方面同时兼顾了制冷剂的环保和安全特性,在GWP<150的基础上同时保证安全等级不低于A2L,另一方面同时保证了高温制冷和低温制热性能,能效与R134a基本相当,容积制冷/制热能力提升10%以上,最高可提高121%。
