Embodiment 1

[0029] Propane accounting for 80% of the total mass and isobutane accounting for 20% of the total mass are mixed to form a hydrocarbon refrigerant replacing R22.

Embodiment 2

[0031] Propane accounting for 84% of the total mass and isobutane accounting for 16% of the total mass are mixed to form a hydrocarbon refrigerant replacing R22.

Embodiment 3

[0033] Propane accounting for 89% of the total mass and isobutane accounting for 11% of the total mass are mixed to form a hydrocarbon refrigerant replacing R22.

[0034] The above-mentioned refrigerant adopts the method and device described in a patented technology (named: a refrigerant tank of less than 1000 ml, patent number: ZL200610096857.3) previously authorized by the applicant of this case to carry out the canning and discharge of the refrigerant .

[0035] A special refrigerant tank is used in this patented technology, its structure is as follows figure 1 As shown, it consists of a tank body 40 and a cover 10. A gasket 14 is placed in a cylindrical boss 11 at the center of the cover 10, and a threaded aerosol valve is placed in the boss. This momentary threaded aerosol valve is made up of valve seat 21, valve core 22, and stage clip 23, stage clip 23 is placed in the inner hole 25 of valve seat, valve core 22 is connected on the free end of stage clip 23 upper side, ...

Abstract

The invention discloses a hydrocarbon refrigerant replacing R22, which comprises propane and isobutene; the propane accounts for 80 to 89 percent of the total mass; the isobutene accounts for 11 to 20 percent of the total mass. The hydrocarbon refrigerant is canned by a special refrigerating can; and the hydrocarbon refrigerant in the refrigerating can is discharged by a special bottle opener according to demands. The hydrocarbon refrigerant has a better filling characteristic, is mutually soluble with the existing lubricant, can be used in the refrigerating device of the existing R22 directly, can lead the running of refrigerating systems to be more optimized and also greatly improves the service life of compressors. The problems of ozonosphere destroying and higher greenhouse air discharge index caused by using the R22 refrigerant are solved. Moreover, the running noise is low, the self density is low, transport capacity can be saved and transport cost can be reduced. The special refrigerating can ensures the extreme low water content of the refrigerant in the can; and the special bottle opener can lead the refrigerant to be discharged according to demands, thus not only saving the resources, but also having no pollution as well as ensuring use safety.

Description

technical field [0001] The invention relates to a refrigerant, in particular to a hydrocarbon refrigerant replacing R22. Background technique [0002] In April 2003, the Chinese government formally promised to comply with the "Copenhagen Amendment" formulated in 1993, and to phase out the international obligations of HCFCs (including R22). The amendment stipulates that for developing countries, the production of HCFCs will be frozen from 2016, and HCFCs will be completely phased out in 2040, but 15% of the frozen production will be allowed to be used for maintenance. [0003] my country is the world's largest producer of air conditioners, and the export sales of air conditioners are growing rapidly. Facing the general trend of actively engaging in R22 substitution research and accelerating the elimination of R22 (chlorodifluoromethane) in the world, especially European countries, if we emphasize that my country If it takes more than 30 years to finally eliminate R22, it will...
