Wherein, 1-drier, 11-drier packed layer, 12-filter screen, 2-oil-liquid separator, 3-fluid reservoir, 31-fluid reservoir switch, 4-first conveyance conduit, 5-second conveyance conduit, 6-the 3rd conveyance conduit, 7-asepwirator pump, 8-air-conditioner outdoor unit, 81-high pressure valve, 82-low pressure valve.
Detailed description of the invention
Now with specific embodiment, the present invention's technical scheme required for protection is described in further detail by reference to the accompanying drawings.
Shown in accompanying drawing 1, air-conditioning refrigerant retracting device in the present embodiment comprises drier 1, oil-liquid separator 2, fluid reservoir 3, first conveyance conduit 4, second conveyance conduit 5 being with asepwirator pump 7 and the 3rd conveyance conduit 6.
Wherein drier 1 is for carrying out drying and filtration fraction impurity to coolant mixture, drier packed layer 11 is provided with in the middle part of it, a large amount of drier is filled with in drier packed layer 11, the upper and lower surface of drier packed layer 11 is filter screen 12 simultaneously, for separating and supporting drier, leave a blank below drier packed layer 11, offer in the bottom of drier 1 can the oil return opening of external air-conditioner outdoor unit 8 low pressure valve 82 simultaneously.Oil-liquid separator 2 is for carrying out fluid separation to coolant mixture, and its inside contains the lubricating oil separated from coolant mixture for a long time, and offering equally bottom oil-liquid separator 2 can the oil return opening of external air-conditioner outdoor unit 8 low pressure valve 82.Fluid reservoir 3 is for collecting and store the cooling agent after separation and purification.
First conveyance conduit 4 is for being communicated with air-conditioner outdoor unit 8 and drier 1, and its entrance can connect the high pressure valve 81 of air-conditioner outdoor unit 8, and its outlet is positioned at the drier packed layer 11 of drier 1.Second conveyance conduit 5 is for being communicated with drier 1 and oil-liquid separator 2, and its entrance is positioned at above drier packed layer 11, and its outlet is positioned at below the liquid level of oil-liquid separator 2.3rd oil pipeline is for being communicated with oil-liquid separator 2 and fluid reservoir 3, and its entrance is positioned at the ullage of oil-liquid separator 2, and its outlet connects fluid reservoir 3, and the outlet of the 3rd oil pipeline in the present embodiment is also provided with fluid reservoir switch 31.
After refrigerant mixture is discharged from high pressure valve 81, be introduced in drier 1, because the outlet of the first conveyance conduit 4 is positioned at drier packed layer 11, therefore coolant mixture fully can contact with drier and carry out impurity that is dry and that simultaneously filter out in mixture, parts of lubricating oil when flow velocity is larger in mixing can be separated and be back in the low pressure valve 82 of air-conditioner outdoor unit 8 by oil return opening, refrigerant mixture after dry filter flows in oil-liquid separator 2 by the second conveyance conduit 5 again, isolate the lubricating oil in refrigerant mixture further, lubricating oil is back in the low pressure valve 82 of air-conditioner outdoor unit 8 by oil return opening equally, cold-producing medium in oil-liquid separator 2 sucks in fluid reservoir 3 finally by asepwirator pump 7, realize storing the recovery of cold-producing medium.When air-conditioner outdoor unit 8 starts, its high pressure valve 81 is in opening, its low pressure valve 82 is in closed condition, so negative pressure state has been pumped in air-conditioner outdoor unit 8 inside, air-conditioner outdoor unit 8 now can be stopped to run, close its high pressure valve 81, open its low pressure valve 82 again, lubricating oil can be back to low pressure valve 82 smoothly by oil return opening, is recovered in whole air-conditioning system, this completes the recovery of whole cold-producing medium, lubricating oil.
