Embodiment 1

[0030] The three components of trifluoroiodomethane (R13I1), fluoroethane (R161) and isobutane (R600a) are physically mixed in a liquid phase at room temperature at a mass percentage of 50:47:3 as a refrigerant.

Embodiment 2

[0032] The four components of trifluoroiodomethane (R13I1), fluoroethane (R161), isobutane (R600a) and 2,3,3,3-tetrafluoropropene (R1234yf) were mixed in the normal temperature liquid phase according to the ratio of 49:43 : 3:5 mass percentage for physical mixing as refrigerant.

Embodiment 3

[0034] The four components of trifluoroiodomethane (R13I1), fluoroethane (R161), isobutane (R600a) and dimethyl ether (RE170) were carried out in the normal temperature liquid phase according to the mass percentage of 50:42:3:5 A physical mix acts as a refrigerant.

Abstract

The invention provides a mixed refrigerant. The mixed refrigerant is prepared from trifluoroiodomethane, fluoroethane and a third component, wherein the third component is isobutane or carbon dioxide.By combining the trifluoroiodomethane with the fluoroethane and the isobutane or carbon dioxide, the GWP of the mixed refrigerant is greatly reduced to meet the GWP requirements of automotive air conditioning refrigerants; the trifluoroiodomethane is a flame retardant, and by adding the flame retardant, the flammability of the mixed refrigerant can be weakened to meet the safety requirements; inaddition, the ODP value of each component is zero, and the damage to the ozone layer is not caused even if the mixed refrigerant is in use for a long time. Thus, the mixed refrigerant has a low GWP and can meet the requirements of the automotive air conditioning refrigerants.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a mixed refrigerant. 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. Therefore, the replacement of high-GWP refrigerant R134a, which is widely used in automotive air-conditioning, has become an inevitable trend, but no perfect alternative has yet been found. Since the mixed working fluid 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 at home and abroad. [0003] At present, there are...
