Problems solved by technology

[0004] The inventor understands that the hydrofluorocarbon (HFOs) refrigerants such as R1234ze and R1234yf jointly developed by Honeywell and DuPont have both excellent performance and environmental protection and have received extensive attention. However, due to the use restrictions of HFOs themselves, still Can not better solve the problem of high GWP value

Embodiment 1

[0023] In a typical implementation of the present disclosure, a refrigerant mixture is provided, which is composed of propane and butane, butane is n-butane or isobutane, propane accounts for more than 10 wt% of the composition, and butane The substance mass fraction is greater than 30wt%. When the butane is isobutane: propane accounts for more than 10 wt% to 60 wt% of the composition, and isobutane accounts for 40 wt% to 90 wt% of the composition. When butane is n-butane: propane accounts for 10wt% to 70wt% of the mass of the composition, and n-butane accounts for 30wt% to 90wt% of the mass of the composition.

[0024] The above-mentioned components are all hydrocarbon refrigerants, with an ozone depletion potential (ODP) of 0 and a very low GWP value, and no substances harmful to the environment will be produced during the refrigeration process, so it has excellent environmental protection.

[0025] Wherein, the basic parameters for each component are as shown in Table 1: ...

Embodiment 2

[0031] Another typical implementation of the present disclosure proposes a mixed working medium. The mixed working medium includes the refrigerant mixture as described in Example 1, and the mixed working medium is charged into the refrigeration system as the refrigerant.

[0032] In other embodiments, other additives can also be added to the mixed working fluid according to requirements, so as to adapt to the operation requirements of different compressors, improve the stability of compressor operation, and the like.

Embodiment 3

[0034] In yet another embodiment of the present disclosure, a compressor using the refrigerant mixture as described in Example 1 is proposed.

Abstract

The invention provides a refrigerant mixture, a mixed working medium and a compressor, and relates to the technical field of refrigeration, the refrigerant mixture is composed of propane and butane, the butane is isobutane, the propane accounts for 10 wt%-60 wt% of the mass of the composition, and the isobutane accounts for 40 wt%-90 wt% of the mass of the composition; or the butane is n-butane, the propane accounts for 10wt%-70wt% of the mass of the composition, and the n-butane accounts for 30wt%-90wt% of the mass of the composition. According to the refrigerant mixture disclosed by the invention, the refrigerant mixture has a relatively low global warming potential (GWP) value by exerting a synergistic effect among the refrigerants, and the problem that the GWP value of an existing R134a refrigerant is relatively high is solved.

Description

technical field [0001] The present disclosure relates to the technical field of refrigeration, in particular to a refrigerant mixture, a mixed working medium and a compressor. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Due to the greenhouse effect of the atmosphere, hydrofluorocarbon refrigerants (HFCs) such as R134a face stringent reduction calculations due to their very high global warming potential (GWP) values, are restricted by various countries, and are gradually being used disuse. [0004] The inventor understands that the hydrofluorocarbon (HFOs) refrigerants such as R1234ze and R1234yf jointly developed by Honeywell and DuPont have both excellent performance and environmental protection and have received extensive attention. However, due to the use restrictions of HFOs themselves, still Can not better solve the problem of...
