When the refrigerant gas and the non-condensable gas are introduced into the purge unit through the first passage connected to the inlet side, the purge unit exchanges heat through the liquid refrigerant introduced through the second passage connected to the outlet side of the condenser. The refrigerant gas is liquefied, and the non-condensable gas is separated.

 However, the prior art has a complexity of having a plurality of flow paths and valves in order to exchange heat with the liquid refrigerant flowing through the condenser outlet to the purge unit, and the liquid refrigerant that has completed the heat exchange in the purge unit again becomes a high temperature main tank. In order to solve this problem, power consumption for separation of non-condensable gas has a big problem because the refrigerant temperature must be lowered by a separate cooling device or an expansion valve.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In general, when looking at the refrigerant recovered in the refrigerant recovery of the refrigerator (A), the ratio of the liquid refrigerant is recovered by mixing about 70% of the ratio of the gas refrigerant to about 30%. The mixed and recovered refrigerant is conventionally recovered only part of the liquid refrigerant and the rest is released into the atmosphere occurs a problem of refrigerant loss and environmental pollution, the present invention is to convert the recovered gas refrigerant to a liquid to solve this problem It is characterized in that the filter unit for recovering the entire amount of the coolant and to remove the oil or other foreign matter contained in the recovered coolant.

2 to 3, the main tank 200 for storing the refrigerant introduced into the refrigerant inlet unit 110 is connected to the refrigerator (A) is provided in the main body portion 100, and the main A vacuum pump 300 installed on the refrigerant inlet 110 connected to the tank 200 and a compressor for compressing a mixed refrigerant of gas and liquid stored in the main tank 200 to form a liquid refrigerant. 400, a cooling device 500 for lowering the temperature of the liquid refrigerant discharged from the compressor 400, a refrigerant tank 600 for storing the liquid refrigerant passing through the cooling device 500, and the refrigerant tank Refrigerant outlet portion 610 for discharging the refrigerant stored in the 600 to the outside.

The main body 100 of the present invention is formed in a rectangular enclosure shape and the main tank 200, the vacuum pump 300, the compressor 400, the cooling device 500, the refrigerant tank 600, etc. It is configured and the refrigerant inlet 110 and the refrigerant outlet 610 is formed to the outside, the lower portion of the main body 100 is provided with a moving wheel 120 at each corner and the handle 130 is formed at the top Regardless of the user, the user can conveniently push and pull to move.

The main tank 200 is a refrigerant inlet 110 connected to the main tank 200 to facilitate the introduction of the refrigerant through the refrigerant inlet 110 connected to the refrigerator (A) to recover the refrigerant. The vacuum pump 300 is installed in the suction suction of the refrigerant flows into the main tank 200.

The refrigerant recovered to the main tank 200 forms a mixed state of a liquid and a gas. Since the refrigerant in a gaseous state is lost during reuse, the refrigerant is compressed through a compressor 400 through a process of compressing the refrigerant. Convert to

Typically, the refrigerant cycle is a high-pressure gas refrigerant through a compressor to facilitate heat exchange, and is converted into a liquid refrigerant through a condenser. However, in the present invention, the refrigerant can be sufficiently liquefied by only the pressure of the compressor 400 in order to achieve only the purpose of the refrigerant recovery.

Refrigerant through the compressor 400 of the present invention is the phase change to the liquid phase, but as the pressure is increased the refrigerant is in a high temperature state, because the high temperature refrigerant gives an excessive pressure of the refrigerant tank 600, the refrigerant tank 600 It is preferable to lower the temperature of the refrigerant through the cooling device 500 and then flow into the refrigerant tank 600 before flowing into the).

Cooling apparatus 500 of the present invention is provided with a water-cooling type to increase the cooling efficiency, the coolant with water as a coolant supplied from the outside to circulate through the cooling water pipeline 510 to cool the liquid refrigerant temperature passing through the compressor 400 By lowering the pressure to prevent the evaporation of the refrigerant when easily discharged to maintain an appropriate amount of the internal pressure of the refrigerant tank (600).
