Embodiment 1

[0055] Example 1, the three components of ammonia (R717), difluoromethane (R32), and trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E)) were prepared according to the The mass ratio of 76:12:12 is physically mixed to obtain an environmentally friendly mixed working fluid.

[0056] That is, in the state of liquid phase at normal temperature and pressure, the ammonia (R717), the difluoromethane (R32) and the trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E) ) in a mass ratio of 76:12:12.

Embodiment 2

[0057] Example 2, the three components of ammonia (R717), difluoromethane (R32), and trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E)) are prepared according to the The mass ratio of 76:16:8 is physically mixed to obtain an environmentally friendly mixed working fluid.

[0058] That is, in the state of liquid phase at normal temperature and pressure, the ammonia (R717), the difluoromethane (R32) and the trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E) ) The mass ratio is 76:16:8.

Embodiment 3

[0059] Example 3, the three components of ammonia (R717), difluoromethane (R32), and trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E)) were prepared according to the The mass ratio of 76:20:4 is physically mixed to obtain an environmentally friendly mixed working fluid.

[0060] That is, in the state of liquid phase at normal temperature and pressure, the ammonia (R717), the difluoromethane (R32) and the trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E) ) The mass ratio is 76:20:4.

Abstract

The invention provides a mixed refrigerant and an air conditioning system. The mixed refrigerant comprises a first component, a second component and a third component, the first component is ammonia,the second component is difluoromethane, and the third component is trans-1-chloro-3, 3, 3-trifluoropropene or 1, 1, 1-trifluoroethane. The mixed refrigerant provided by the invention has low GWP andgood thermal performance, the GWP value of the mixed refrigerant can be lower than 150, the COP energy of the mixed refrigerant is much higher than that of R134a, the volume refrigerating capacity ofthe mixed refrigerant is much higher than that of R134a, the problem that other refrigerants replacing R134a are high in GWP is effectively solved, and meanwhile the problem that other refrigerants are poor in thermal performance is solved. The sliding temperature of the mixed working medium can be lower than 0.5 DEG C, adverse effects caused by temperature sliding are eliminated, and potential safety hazards caused by combustible refrigerants can be reduced or even eliminated through the secondary circuit automobile air conditioning system.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a mixed refrigerant and an air-conditioning system. 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. In the F-gas Act of the European Union, the GWP of the refrigerant used in the automotive air-conditioning system is required to be less than 150, but a perfect replacement for R134a (GWP=1430) has not yet been found, and due to the characteristics of R134a itself, the use of R134a The heating capacity per unit volume of the automotive air-conditioning heat pump system is low, which makes the compressor volume larger (larger displacement), and finally make...
