Technical field

The present invention relates to refrigeration technology fields, in particular to a kind of portable coolant recycling machine and refrigerant recovering system System.

Background technique

In order to protect ozone layer, improve the living environment of the mankind, it is empty that the government organs of countries in the world all successively put into effect refrigeration The policy that consumption ozone substance (mainly CFC and HCFC) must not be discharged to atmosphere in device is adjusted, while with refrigerant price It constantly raises up, so that the recycling and reuse of refrigerant become the inevitable choice of development, for this purpose, specially developing a kind of return in society Receive and recycle the coolant reclaiming machine of refrigerant.

But the container used in existing coolant reclaiming machine for storing recycling refrigerant is a closed recycling Bucket, when such as recycling freon, the gas-liquid mixture of freon can become the freon of the high entropy of high pressure by swelling heat absorption in recycling bin Gas often causes gas to block up phenomenon in recycling bin, can smoothly enter into freon to be recycled can not persistently in recycling bin, If the recycling machine is appointed to work on, or even it will cause the compressor damage of the recycling machine.

Summary of the invention

The main object of the present invention is to propose a kind of portable coolant recycling machine, it is intended to be improved to the recovery efficiency of refrigerant simultaneously Solves gas stifled the phenomenon that can not compressing, to recycling bin be needed to take out before solving common coolant reclaiming machine recycling freon true Empty phenomenon.

To achieve the above object, a kind of portable coolant recycling machine proposed by the present invention, including it is compressor, condenser, swollen Swollen valve and recycling bin, the outlet of the compressor connect the import of the condenser, and the outlet connection of the condenser is described swollen The import of swollen valve, the outlet of the expansion valve connect the air inlet of the recycling bin, and there are two gas returning port, institutes for the compressor tool The gas outlet for stating recycling bin is connected with return-air valve, and the gas outlet of the recycling bin is connected by the return-air valve and through a muffler A gas returning port in two gas returning ports of the compressor, another described gas returning port of the compressor to Connect refrigerant equipment to be recycled.

Optionally, the refrigerant equipment to be recycled includes refrigerator, freezer.

Optionally, the gas outlet of the recycling bin is opened in the top of the recycling bin.

Optionally, the muffler is equipped with one-way conduction valve.

Optionally, which is equipped with high-low pressure protective device, returns to when being recovered refrigerant inside equipment Protection act recycling machine stops working when low pressure is lower than 0 kilogram when harvesting, and blocks up or returns when recyclable device is in the stifled liquid of gas Irregular operatings, which generate high voltage protective movement when high pressure is higher than 20 kilograms, when receipts bucket expires bottle etc. makes recovery system stop working.

Optionally, the compressor is used for the high entropy Freon gas of the condenser conveying high-pressure.

Optionally, the condenser is used for the expansion valve conveying high-pressure low enthalpy Freon gas.

Optionally, the expansion valve is used for the freon gas liquid mixture to the recycling bin conveying high-pressure low enthalpy.

Optionally, the recycling bin is used to be uncompressed and expansion of absorbing heat by the muffler to compressor conveying The Freon gas of the high entropy of low pressure afterwards.

The present embodiment also provides a kind of refrigerant recovery system, including above-mentioned portable coolant recycling machine.

In the technical solution of the present embodiment, by taking one of numerous refrigerants freon as an example, it will be recycled by return-air duct Go out recycling bin in the continuous aerial drainage of gaseous freon in bucket, leaves the refrigerant of aobvious liquid.Therefore it is possible to prevente effectively from The generation that gas blocks up phenomenon occurs in recycling bin, to ensure the normal operation of the equipment, and not by gaseous state freon in recycling bin The disconnected air inlet for being circulated back to compressor can make the fluorine chlorine as much as possible for storing liquid in recycling bin high, to improve recycling Efficiency.(because the cold media gas of gas-liquid mixed enters in recycling bin after throttling set vaporization, refrigerant is in vaporization Absorb simultaneously heat as high entropy gas from newly pass back into compressor carry out and system to be recycled in the refrigerant that sucks together into Enter new circulation.Vaporization makes generation cooling effect temperature within the barrel in recycling bin that can drop to 0 DEG C hereinafter, low temperature can in recycling bin Refrigerant is set further to liquefy, so that it is more and more to form the benign refrigerant for following bad recycling).
