Embodiment 1

[0043] The three components of iodotrifluoromethane (R13I1), fluoroethane (R161) and 2,3,3,3-tetrafluoropropene (R1234yf) were subjected to a physical experiment at a mass percentage of 49:45:6 in a liquid phase at room temperature. mixed as a refrigerant.

Embodiment 2

[0045] The four components of trifluoroiodomethane (R13I1), fluoroethane (R161), 2,3,3,3-tetrafluoropropene (R1234yf) and dimethyl ether (RE170) were mixed in a liquid phase at room temperature in a ratio of 49:43 : 6:2 mass percentage for physical mixing as refrigerant.

Embodiment 3

[0047] Trifluoroiodomethane (R13I1), fluoroethane (R161), 2,3,3,3-tetrafluoropropene (R1234yf) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E) ) The four components are physically mixed in a mass percentage of 47:42:5:6 in a liquid phase at normal temperature as a refrigerant.

Abstract

The invention provides a refrigerant composition and a production method thereof. The refrigerant composition comprises a first component, a second component and a third component, wherein the first component is trifluoroiodomethane, the second component is ethyl fluoride, and the third component is 2,3,3,3-tetrafluoropropene, propane, dimethyl ether or methyl fluoride. The refrigerant compositionhas good environmental performance, most GWPs are lower than 100, moreover, compared with R134a, the refrigerant composition has high displacement refrigerating capacity, an EER value is equivalent to that of the R134a, and the problem of insufficient low-temperature heating performance of the R134a is solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerant composition and a preparation method thereof. Background technique [0002] Currently, HFCs refrigerants, which are widely used in refrigeration and air-conditioning industries, 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 tetrafluoroethane (R134a) widely used in automotive air-conditioning has become an inevitable trend. In addition, tetrafluoroethane Alkanes also have the problem of insufficient heating at low temperatures. Since the mixed working fluid as a refrigerant composition has the characteristics of balancing the physical properties of the refrigerant, it plays a vital role in the refrigerant repl...
