Embodiment

[0046] The refrigerant recovery and filling machine for automobile air conditioners of the present invention has four functions of refrigerant recovery, vacuuming, refrigerant filling and internal refrigerant self-circulation of the device.

[0047] (1) Refrigerant recovery:

[0048] When the refrigerant is recovered, the compressor 71 of the compression mechanism 7 starts to run, and the self-circulation solenoid valve 31 and the recovery solenoid valve 32 are in a conduction state. The refrigerant in the automobile air conditioner enters the refrigerant recovery through the high-pressure valve 22 and the low-pressure valve 23. The refrigerant passes through the self-circulation electromagnetic valve 31, the recovery electromagnetic valve 32, and the one-way valve 36. After being decompressed and vaporized by the expansion valve 4, the refrigerant enters the heat exchange oil separator 5 Degreasing, the gaseous refrigerant after absorbing heat passes through the dry filter 6 ...

Abstract

The invention discloses a recycling and filling machine for an automobile air conditioner refrigerant and application of the recycling and filling machine. The machine comprises a high-low pressure connector, a high-low pressure valve group, a confluence valve block, an expansion valve, a heat exchange oil separator, a drying filter, a compression mechanism and a working tank. The recycling and filling machine is connected with an automobile air conditioner through the high-low pressure connector. The high-low pressure connector, the high-low pressure valve group, the confluence valve block, the expansion valve and the heat exchange oil separator are connected in sequence, the heat exchange oil separator is further connected with the drying filter and the compression mechanism in sequence,and the compression mechanism is connected with the heat exchange oil separator and the working tank. According to the recycling and filling machine for the automobile air conditioner refrigerant andapplication of the recycling and filling machine, the structure is simple, recycling, purifying and filling of the refrigerant are integrated, resources are not wasted, no potential threat is causedto global climate warming, device stability is good, the failure rate is low, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of automobile maintenance equipment, and in particular relates to a recycling and filling machine for automobile air-conditioning refrigerant and its application.
