Problems solved by technology
Even if there are patents and products for portable refrigerant recovery machines, they are all aimed at air conditioner maintenance. The volume limit determines that each recovery machine can only recover small-quality Freon refrigerants, and cannot continuously recover the release of multiple air conditioners. A large amount of refrigerant, and the patent and product of the refrigerant recovery device of the large-scale tank device, due to the characteristics of the gas-liquid two-phase pressure balance of the refrigerant, it is difficult to ensure that most of the refrigerant can be recovered, making the recovery of the refrigerant Not thorough enough
In addition, there is a lack of related equipment that directly injects the recovered refrigerant into the air conditioner without complicated treatment

The invention discloses a recycle system of air-conditioning outdoor machine refrigerant, comprising a refrigerating device and a refrigerant circulation loop composed of a compressor, a four-way reversing valve, a coil, a throttle mechanism and a heat exchanger; the air-conditioning outdoor machine is arranged on the air outlet of an air flue; the recycle system of air-conditioning outdoor machine refrigerant is provided with a recovering tank in which the coil is contained; when the refrigerant is recovered, refrigerant is communicated with the air-conditioning outdoor machine via a recovering tank ingress pipe; when the refrigerant is filled, the refrigerant is communicated with the air-conditioning outdoor machine via the recovering tank delivery pipe. The recycle system of air-conditioning outdoor machine refrigerant provided in the invention not only can thoroughly recover a great amount of air-conditioning outdoor machine refrigerant to be recovered but also can directly fill recovered refrigerant into an air conditioning to be reused without complicated processing, thus realizing environment protection and lowering cost.
Description
technical field [0001] The invention relates to the field of adding and discharging refrigerant, in particular to a system for recovering and reusing refrigerant of an outdoor unit of an air conditioner. Background technique [0002] As we all know, the emission of freon gas will destroy the ozone layer of the atmosphere, cause the greenhouse effect, and cause a series of environmental problems. There are few related devices and methods to recycle or reuse Freon used in research and development. Even if there are patents and products for portable refrigerant recovery machines, they are all aimed at air conditioner maintenance. The volume limit determines that each recovery machine can only recover small-quality Freon refrigerants, and cannot continuously recover the release of multiple air conditioners. A large amount of refrigerant, and the patent and product of the refrigerant recovery device of the large-scale tank device, due to the characteristics of the gas-liquid two...
