Embodiment 1

[0034] A kind of automotive air-conditioning refrigerant mixture embodiment 1 of the present invention comprises the following components, and each component is respectively according to parts by weight:

[0035]

[0036] The filling method of this kind of automobile air-conditioning refrigerant mixture comprises: a port adapter, a hose provided with a valve and a sealed aerosol tank containing the automobile air-conditioning refrigerant mixture; Connect the adapter with the service port on the car air conditioning system, connect one end of the hose to the port adapter, and connect the other end of the hose to the interface of the aerosol can; open the Valve to fill the car air conditioning refrigerant mixture in the aerosol can into the car air conditioning system.

[0037] Such as Figures 1 to 3As shown, the filling device used in the method of filling the refrigerant mixture of the automobile air conditioner includes a port adapter 1, a hose 2 with a valve 21 and a se...

Embodiment 2

[0040] A kind of automotive air-conditioning refrigerant mixture embodiment 2 of the present invention comprises the following components, and each component is respectively according to parts by weight:

[0041]

[0042]

[0043] Its filling method and used filling device are identical with embodiment 1.

Embodiment 3

[0044] A kind of automotive air-conditioning refrigerant mixture embodiment 3 of the present invention comprises the following components, and each component is respectively according to parts by weight:

[0045]

[0046] Its filling method and used filling device are identical with embodiment 1.

[0047] After the old car that originally used R-12 was filled with the refrigerant mixture of the car air conditioner in Examples 1 to 3, the car air conditioner could work normally, and the cooling effect was equivalent to that of the new car air conditioner that used R-12. The use of O-rings The service life is extended by 2 to 3 times, the location of the leak can be clearly seen when it leaks, and it can still be used in case of a slight leak, which greatly reduces the frequency of replacement. In Example 3, when the dosage of 1,2-triphenylene and benzoantrone is 2:1, a bright fluorescent yellow color can be produced, and the shelf life is also significantly improved.

Abstract

The invention discloses an automotive air conditioner refrigerant mixture. The automotive air conditioner refrigerant mixture is prepared from the following components in parts by weight: 100 parts of tetrafluoroethane, 15-25 parts of lubricating agent, 0.03-2 parts of ultraviolet fluorescent dye, 0.03-2 parts of cyclohexanone, 0.03-2 parts of methyl alcohol, 0.03-2 parts of solubilizing agent and 0.02-2 parts of acetic acid. The invention also discloses a filling method and a filling device of the automotive air conditioner refrigerant mixture. The automotive air conditioner refrigerant mixture has the advantages that a refrigerant R-134a is modified by the automotive air conditioner refrigerant mixture and then is directly filled into an old automotive air conditioner, spillage or leakage of harmful chemical substances in a refitting process is reduced, the blank that the refrigerant R-134a can not be directly filled in an old car originally adopting R-12 in the prior art is filled up, and the problem that oil return of refrigeration equipment is poor can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of automobile air-conditioning refrigerants, relates to an automobile air-conditioning refrigerant mixture, and also relates to a filling method and a filling device for the automobile air-conditioning refrigerant mixture. Background technique [0002] For a long time, R-12 has been used as the primary refrigerant for automotive air conditioners. Lubricants for air conditioning equipment are technically known as R-12 specialty chemicals or chemical mixtures. R-12 is CFCs (chlorofluorocarbons) and HCFCs (hydrofluorocarbons) refrigerants, the use of CFCs (hydrochlorofluorocarbons) and HCFCs (hydrofluorocarbons) refrigerants will cause damage to the atmospheric ozone layer, and as the amount of use increases The bigger it gets, the worse the problem becomes. Therefore, the commonly used refrigerants R-12 and R-22 have been eliminated from the field of air-conditioning refrigerants. The refrigerants widely us...
