Embodiment 1

[0039] The three components of trifluoroiodomethane (R13I1), propylene (R1270) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) were mixed according to the ratio of 43:44:13 under normal temperature liquid phase The mass percent is physically mixed as a refrigerant.

Embodiment 2

[0041] Trifluoroiodomethane (R13I1), propene (R1270), trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) and 2,3,3,3-tetrafluoropropene (R1234yf) four The two components are physically mixed at a mass percentage of 43:44:6:7 in a liquid phase at room temperature as a refrigerant.

Embodiment 3

[0043] The four components of trifluoroiodomethane (R13I1), propylene (R1270), trans-1,3,3,3-tetrafluoropropene (R1234ze (E)) and tetrafluoroethane (R134a) were mixed in liquid phase at room temperature According to the mass percentage of 44:44:6:6, it is physically mixed as a refrigerant.

Abstract

The invention provides a mixed refrigerant and a refrigerating device with the same. The mixed refrigerant comprises trifluoroiodomethane, propylene and a third component, and the third component is selected from 2,3,3,3-tetrafluoropropene and / or trans-1,3,3,3-tetrafluoropropene. The mixed refrigerant comprises multiple refrigerants, and by exerting the synergistic effect of the refrigerants, themixed refrigerant has a low GWP value (lower than 100) and a high volumetric refrigerating capacity and volumetric heating capacity; the trifluoroiodomethane has excellent flame retardancy, thus, theaddition of the trifluoroiodomethane can weaken the flammability of the refrigerants, and then the safety of the mixed refrigerant is improved. Thus, by adopting the mixed refrigerant for refrigeration, the refrigerating and heating effects of the mixed refrigerant can be improved, the problems that an existing R134a refrigerant has a low low-temperature heating capacity and a high GWP value are solved, and substances harmful to the environment will not be generated in the refrigerating process.

Description

technical field [0001] The invention relates to the field of refrigerants, in particular to a mixed refrigerant and a refrigeration device containing it. Background technique [0002] Hydrofluorocarbon refrigerants (HFCs), which are currently widely used in the refrigeration and air-conditioning industry, are facing stringent reduction plans due to their very high global warming potential (GWP). At the same time, the European Union's automotive air-conditioning directive requires that the GWP of automotive air-conditioning refrigerants be no higher than 150, so the replacement of high-GWP refrigerant R134a, which is widely used in automotive air-conditioning, has become an inevitable trend, but a more perfect alternative has not yet been found. Because the mixed refrigerant has the characteristics of balancing the physical properties of the refrigerant, it plays a vital role in the refrigerant replacement scheme, and has become a research hotspot for scholars and enterprises...
