Problems solved by technology

Due to its excellent environmental protection performance (ODP=0, GWP=3), the natural working medium R290 meets the current requirements for the environmental performance of refrigerants, and is used in refrigeration applications such as household air conditioners, mobile air conditioners, refrigerators, and small freezers. It has strong flammability (belonging to Class 3 flammable refrigerants), and has a great lack of safety, which makes it difficult to market R290 refrigerants. Therefore, it is necessary to find a kind of refrigerant with good environmental performance, high safety, thermal performance and R290 is an equivalent or even better refrigerant to replace, so as to meet the requirements of refrigerant environmental protection, safety, and high efficiency to the greatest extent.

Embodiment 1

[0022] The three components of trifluoroiodomethane (R13I1), 1,1,2-trifluoroethylene (R1123) and propane (R290) are physically mixed at a mass ratio of 12:4:84 under normal temperature and normal pressure liquid phase An environmentally friendly mixed working fluid is obtained.

Embodiment 2

[0024] The three components of trifluoroiodomethane (R13I1), 1,1,2-trifluoroethylene (R1123) and propane (R290) are physically mixed at a mass ratio of 16:4:80 under normal temperature and pressure liquid phase An environmentally friendly mixed working fluid is obtained.

Embodiment 3

[0026] The three components of trifluoroiodomethane (R13I1), 1,1,2-trifluoroethylene (R1123) and propane (R290) are physically mixed at a mass ratio of 20:4:76 under normal temperature and normal pressure liquid phase An environmentally friendly mixed working fluid is obtained.

Abstract

The invention provides a refrigerant, a preparation method thereof and an air conditioning system. The refrigerant is composed of a first component, a second component and a third component, wherein the first component is trifluoroiodomethane, the second component is 1, 1, 2-trifluoroethylene, and the third component is one of HC refrigerants. The environment-friendly mixed refrigerant is used forreplacing R290, and the technical problems that the R290 refrigerant is high in combustibility and poor in safety performance are solved while it is guaranteed that the environment-friendly performance of the refrigerant is good and the thermal performance is equivalent to that of the R290 refrigerant.

Description

technical field [0001] The application belongs to the technical field of air-conditioning systems, and in particular relates to a refrigerant, a preparation method thereof, and an air-conditioning system. Background technique [0002] At present, global warming has become a problem that human society needs to face together. With the adoption of the Kigali Amendment to the Montreal Protocol in early 2019, the requirements for carbon emissions at home and abroad have become increasingly stringent, and HFCs refrigerants such as R32 and R410A are facing reductions. It is imminent to find a refrigerant that does not destroy the ozone layer and has a lower GWP value to replace the current high GWP refrigerant. Due to its excellent environmental protection performance (ODP=0, GWP=3), the natural working medium R290 meets the current requirements for the environmental performance of refrigerants, and is used in refrigeration applications such as household air conditioners, mobile ai...
