Contain fluorine element in R22 refrigerant, have destruction to the ozone layer in atmosphere, so clear stipulaties needs take in recent years in the world
Disappear use, but is related to after sale with alternative cost problem, and the inevitable longer period of time afterwards of R22 refrigerant is interior to be joined with people
It is tied.And it is exactly R410A that environmental protection refrigerant is most commonly used at present, but in view of alternative cost and refrigerant itself to system
Stress problems, promotion prospect is still pessimistic.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of air-conditionings that can recycle air-conditioning refrigerant
Refrigerant recovering apparatus.
In order to achieve the goal above, claimed technical solution of the invention is:
A kind of air-conditioning refrigerant recyclable device, including drier, oil-liquid separator, the fluid reservoir with asepwirator pump, first defeated
Send pipeline, the second conveyance conduit and third conveyance conduit；It is provided with desiccant filled layer in the middle part of the drier, while in drying
The upper and lower faces of agent filled layer are equipped with strainer, and it is low that the bottom of drier and oil-liquid separator offers external air-conditioner outdoor unit
The oil return opening of pressure valve；In the first conveyance conduit insertion desiccant filled layer, the high pressure valve of the external air-conditioner outdoor unit of entrance,
It, which is exported, is located in desiccant filled layer；The second conveyance conduit connection drier and oil-liquid separator, entrance are located at dry
Above drying prescription filled layer, outlet is located at below the liquid level of oil-liquid separator；The third conveyance conduit is connected to oil-liquid separator
And fluid reservoir, entrance are located at the ullage of oil-liquid separator.
Further, fluid reservoir switch is additionally provided on the third conveyance conduit.
The beneficial effects of the present invention are: air-conditioning refrigerant recyclable device of the invention includes interconnected drier, oil
Liquid/gas separator and fluid reservoir, wherein drier can be connected by the high pressure valve of the first conveyance conduit and air-conditioner outdoor unit, refrigerant
Mixture is introduced into drier, after being discharged in high pressure valve since the outlet of the first conveyance conduit is located at desiccant filled layer
It is interior, therefore coolant mixture can come into full contact with desiccant and be dried and filter out simultaneously the impurity in mixture, work as stream
Parts of lubricating oil when speed is larger in mixing can be separated and be flowed back into the low pressure valve of air-conditioner outdoor unit by oil return opening,
Refrigerant mixture after dry filter flows into oil-liquid separator further through the second conveyance conduit, is further separated out refrigerant
Lubricating oil in mixture, lubricating oil equally passes through oil return opening and flows back into the low pressure valve of air-conditioner outdoor unit, in oil-liquid separator
Refrigerant finally by asepwirator pump sucking fluid reservoir, realize and the recycling of refrigerant stored.
Detailed description of the invention
Fig. 1 is the principle of the present invention figure.
Wherein, 1- drier, 11- desiccant filled layer, 12- strainer, 2- oil-liquid separator, 3- fluid reservoir, 31- fluid reservoir
Switch, the first conveyance conduit of 4-, the second conveyance conduit of 5-, 6- third conveyance conduit, 7- asepwirator pump, 8- air-conditioner outdoor unit, 81- high
Pressure valve, 82- low pressure valve.
Specific embodiment
Claimed technical solution of the invention is described in further detail now in conjunction with the drawings and specific embodiments.
Referring to figure 1, air-conditioning refrigerant recyclable device in the present embodiment includes drier 1, oil-liquid separator
2, the fluid reservoir 3 with asepwirator pump 7, the first conveyance conduit 4, the second conveyance conduit 5 and third conveyance conduit 6.
Wherein drier 1 is for being dried coolant mixture and filtration fraction impurity, and the middle part is provided with dryings
Agent filled layer 11, desiccant filled layer 11 is interior to be filled with a large amount of desiccant, while the upper and lower surface of desiccant filled layer 11 is equal
It leaves a blank below desiccant filled layer 11, while being opened up in the bottom of drier 1 for strainer 12 for separating and supporting desiccant
Have can external 8 low pressure valve 82 of air-conditioner outdoor unit oil return opening.Oil-liquid separator 2 is used to carry out oil liquid point to coolant mixture
From, it is internal to contain the lubricating oil separated from coolant mixture for a long time, it is equally opened up in 2 bottom of oil-liquid separator
Have can external 8 low pressure valve 82 of air-conditioner outdoor unit oil return opening.Fluid reservoir 3 is used to collecting and storing the coolant after isolating and purifying.
For first conveyance conduit 4 for being connected to air-conditioner outdoor unit 8 and drier 1, entrance can connect the height of air-conditioner outdoor unit 8
Pressure valve 81, outlet are located in the desiccant filled layer 11 of drier 1.Second conveyance conduit 5 is for being connected to drier 1 and oil liquid
Separator 2, entrance are located at 11 top of desiccant filled layer, and outlet is located at below the liquid level of oil-liquid separator 2.Third oil transportation
