Embodiment 1

[0043] Example 1, three components of 1,1,1,2,3,3,3-heptafluoropropane (R227ea), ammonia (R717) and 1,1,1-trifluoroethane (R143a) were mixed at normal temperature and pressure Under the liquid phase, the mass ratio of 4:88:8 is physically mixed to obtain an environmentally friendly mixed working fluid.

[0044] That is, in the state of liquid phase at normal temperature and pressure, the 1,1,1,2,3,3,3-heptafluoropropane (R227ea), the ammonia (R717) and the 1,1,1-trifluoroethane The mass ratio of alkane (R143a) is 4:88:8.

Embodiment 2

[0045] Example 2, three components of 1,1,1,2,3,3,3-heptafluoropropane (R227ea), ammonia (R717) and 1,1,1-trifluoroethane (R143a) were mixed at normal temperature and pressure Under the liquid phase, the mass ratio of 4:92:4 is physically mixed to obtain an environmentally friendly mixed working fluid.

[0046] That is, in the state of liquid phase at normal temperature and pressure, the 1,1,1,2,3,3,3-heptafluoropropane (R227ea), the ammonia (R717) and the 1,1,1-trifluoroethane The mass ratio of alkane (R143a) is 4:92:4.

Embodiment 3

[0047] Example 3, three components of 1,1,1,2,3,3,3-heptafluoropropane (R227ea), ammonia (R717) and 1,1,1-trifluoroethane (R143a) were mixed at normal temperature and pressure Under the liquid phase, the mass ratio of 8:88:4 is physically mixed to obtain an environmentally friendly mixed working fluid.

[0048] That is, in the state of liquid phase at normal temperature and pressure, the 1,1,1,2,3,3,3-heptafluoropropane (R227ea), the ammonia (R717) and the 1,1,1-trifluoroethane The mass ratio of alkane (R143a) is 8:88:4.

Abstract

The invention provides a mixed refrigerant, a refrigerating system and an air conditioner. The mixed refrigerant comprises a first component, a second component and a third component, wherein the first component is 1,1,1,2,3,3,3-heptafluoropropane, the second component is ammonia, and the third component is 1,1,1-trifluoroethane or trans-1-chloro-3,3,3-trifluoropropene. The mixed refrigerant has low GWP and good thermal performance, the COP of the mixed refrigerant can reach 108% of that of R134a, the volume refrigerating capacity can reach about 173% of that of the R134a, the problem that other refrigerants replacing the R134a are high in GWP is effectively solved, and the problem that other refrigerants are poor in thermal performance is solved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a mixed refrigerant, a refrigeration system and an air conditioner. Background technique [0002] With the increasingly serious trend of environmental protection, regarding the "greenhouse effect" of HFCs, the Montreal Protocol Amendment requires a refrigerant that does not destroy the ozone layer and has a lower GWP value to replace the current high-GWP refrigerant and be effectively used in air-conditioning systems middle. However, a more perfect alternative has not been found yet. Since the mixed working medium has the characteristics of balanced refrigerant properties, it is possible to prepare a new safe and environmentally friendly refrigerant by mixing multiple refrigerants. [0003] Patent No. 201910050560.0 proposes a mixed refrigerant to replace R134a, but the thermodynamic performance of the replaced mixed refrigerant is only comparable to that of R1...
