본 고안은 차량등의 에어콘등에서 사용되는 과정 생기는 폐냉매가스(프레온가스)의 재생 및 이를 자동으로 충전하는 충전기에 관한 것이다.The present invention relates to a regeneration of waste refrigerant gas (freon gas) generated in the process used in the air conditioner, such as a vehicle and a charger for automatically charging it.

에어콘냉매가스는 장기 사용하게 되면 오일이나 공기등의 이물질이 함침되어 기능을 약화시키기 때문에 일정기간이 지나면 이를 교체해 주고 있는 실정이고 이와같은 교체작업에 있어 폐냉매가스를 그대로 버리면 대기오염의 주요인이 되기 때문에 이를 재생처리하고 있는 실정인바 종래의 폐냉매가스의 재생 처리장치는 노후된 폐냉매가스 탱크에 정제탱크와 연결된 흡입관을 넣어서 콤프레셔의 흡인력으로 흡인하여 이를 정제탱크내에 보낼때 제1, 2차 탱크 사이에 설치되어 있는 코일관의 저항 마찰열에 의해 정제탱크내의 폐냉매가스가 가온 팽창되면서 가스속에 함유된 오일, 공기 기타 불순물이 분해되어지고 분해된 이물질 가운데 오일과 같이 비중이 무거운 것은 하방으로 낙하되고 에어와 같이 비중이 가벼운 것은 정제탱크 상부에 설치되어 있는 배출변을 통해 배출되게 하고 정제된 순수한 냉매가스만 냉각기를 통과한는 과정 냉각되어 충전탱크에 충전하도록 하였던 바 이때 가열에 의해 재생된 가스는 냉각이 되지 않은 상태에서는 충전이 불가능하므로 냉각기에서 냉각시킬 때는 연속 충전작업을 할 수 없어서 30분 가동에 1시간 휴식을 해야 하는 문제점이 있었던 것이다.Air conditioner refrigerant gas is impregnated with foreign substances such as oil or air when it is used for a long period of time, which weakens its function, and it is replaced after a certain period of time. Therefore, the regeneration process of the conventional waste refrigerant gas is put into the old waste refrigerant gas tank inlet pipe connected to the refinery tank and sucked by the suction force of the compressor to send it into the refinery tank between the first and secondary tanks The waste refrigerant gas in the refining tank is warmed and expanded by the resistance frictional heat of the coil pipe installed in the tank, and oil, air, and other impurities contained in the gas are decomposed. Light weight, such as is installed at the top of the purification tank It was discharged through the discharge valve, and only the purified pure refrigerant gas was passed through the cooler and cooled to fill the filling tank. At this time, the gas regenerated by heating cannot be charged without cooling. When it was not possible to do continuous charging work, there was a problem of having to rest for 1 hour for 30 minutes of operation.

따라서 이 문제를 해결하고자 본출원인이 선출원한 폐냉매가스의 재생장치는 종래와는 달리 폐냉매가스 탱크와 콤프레셔 사이에 정체탱크를 설치하되 콤프레셔에 의해 폐냉매가스 탱크에서 흡인된 폐냉매가스가 정제탱크내로 들어올때는 팽창변에 의해 팽창 확산된 후 정제탱크내로 통과하는 배출관에서 발산하는 열에 의해 가온되면서 폐냉매가스에 함유된 오일은 응집되어 정제탱크 내저면에 낙하 수거되게 하고 폐가스속에 함유된 에어등은 정제탱크 상부에 설치된 배출변으로 배출되며 또한 배출관으로 배출되는 정제가스는 냉각기에 의해 냉각된 후 여과휠터를 거쳐 불순물이 여과된 후 충전탱크에 충전될때 이의 온도가 높으면 충전이 불가능하므로 이때는 감지밸브의 작동에 의해 정제가스는 우회관을 통해 흡입관으로 재투입하면서 정제탱크내에서 냉각된 상태로 들어오는 재생냉매가스와 혼합 냉각 감온되면 감지밸브가 이를 감지하여 냉각기의 밸브를 다시 열어 주도록 하고 있는바 본 고안은 이와 같은 원리를 하나의 기구내에 장치하여 폐가스의 재생 및 충전이 자동으로 이루어지게 하므로서 차체의 냉매가스탱크의 간편한 고체로 차체는 항상 순도높은 냉매가스를 사용할 수 있게한 것이다.Therefore, in order to solve this problem, the reclaiming device for waste refrigerant gas, which the applicant has previously applied for, is required to install a stagnation tank between the waste refrigerant gas tank and the compressor, but the waste refrigerant gas sucked from the waste refrigerant gas tank by the compressor is purified. When entering the tank, the oil contained in the waste refrigerant gas agglomerates and falls to the bottom of the refinery tank while it is warmed by the heat radiated from the discharge pipe passing through the expansion tank after expansion and expansion by the expansion valve. The purge gas is discharged to the discharge valve installed in the upper part of the refining tank, and the purge gas discharged to the discharge pipe is cooled by the cooler, and the impurities are filtered through the filtration filter. By operation, the refinery gas is returned to the suction pipe through the bypass pipe, When the refrigerant is mixed with the regenerative refrigerant gas which is cooled in the tank and cooled down, the detection valve detects this and reopens the valve of the chiller. As it is made automatically, the solid body of the refrigerant gas tank of the car body is easy to use high-purity refrigerant gas.

이를 도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail based on the drawings.

몸체(1)의 내부에 격판(1')을 개재시켜 형성된 공실(2)에는 폐냉매가스탱크(8)와 흡입관(4)으로 연결된 정제탱크(3)가 설치되고 그 일촉에는 정제탱크(3)와 연결된 콤프레셔가 설치되어 있으되 이에 연결된 배출관(4')은 정제탱크(3)를 관통한 상태에서 감지밸브(6')를 개재시켜 공실(2')내에 설치된 냉각기(6)와 연결되고 공실(2)내에는 재생냉매가스탱크(8)가 장치되어 있으되 이는 휠터(7)를 개개시킨 상태에서 배출관(4')에 의해 냉각기(6)와 연결되며 한편 흡입관(4)과 배출관(4')은 우회관(4)에 의해 연결되어 있으되 우회관(4)에는 좌우로 감지밸브(9)(9')가 설치되어지고 몸체(1)의 상부에는 압력계(10), 온도계(10'), 진공계(10), 충전용량계(10)와 매인스위치(11) 및 조절장치부(12)가 설치되어진 구조이다.In the empty space 2 formed through the diaphragm 1 'inside the body 1, a purification tank 3 connected to the waste refrigerant gas tank 8 and the suction pipe 4 is installed. ) Is connected to the cooler (6) installed in the vacancy (2 ') via the detection valve (6') through the purification tank (3) in the discharge pipe (4 ') connected to the vacancy (2) The regenerative refrigerant gas tank (8) is provided, which is connected to the cooler (6) by the discharge pipe (4 ') with the filter (7) open, while the suction pipe (4) and the discharge pipe (4'). ) Is connected by a bypass pipe (4), but the detection pipe (9) (9 ') is installed on the bypass pipe (4) to the left and right, and the pressure gauge (10) and the thermometer (10') on the upper part of the body (1). , The vacuum gauge 10, the charge capacitance meter 10, the main switch 11, and the adjusting unit 12 are installed.

이상과 같이 구성된 본 고안은 폐냉매가스의 재생 및 자동 충전기로 사용하는 것인바 이를 사용할 시는 정제탱크(3)와 연결된 흡입관(4)의 일단을 차체에서 수거한 폐냉매가스탱크(8)에 연결한 후 매인스위치(11)를 ON시킴과 동시 조절장치부(12)내의 자동스위치를 ON시키면 콤프레셔(5)가 가동되면서 폐냉매가스탱크(8)내에 있는 폐냉매가스가 정제탱크(3)내로 흡입될때 팽창변(4')에 의해 확산됨과 동시 배출관(4')에서 발산하는 열에 의해 냉매가스가 팽창되면서 폐냉매가스속에 함유된 오일등의 액체는 하부로 낙하 수거되고 에어와 같이 비중이나 압력이 다른 불순물은 배기변(3')을 통해 밖으로 배출된다.The present invention configured as described above is to be used as a regeneration and automatic charger of the waste refrigerant gas, when using one end of the suction pipe (4) connected to the purification tank (3) to the waste refrigerant gas tank (8) collected from the vehicle body When the main switch 11 is turned on and the automatic switch in the control unit 12 is turned on, the compressor (5) is operated, and the waste refrigerant gas in the waste refrigerant gas tank (8) is purified in the refining tank (3). As it is sucked into it, it is diffused by the expansion valve 4 'and the refrigerant gas is expanded by the heat dissipated from the discharge pipe 4', so that liquids such as oil contained in the waste refrigerant gas are collected and dropped to the lower side, and the specific gravity or pressure as These other impurities are discharged out through the exhaust valve 3 '.

그리고 정제탱크(3)내에서 정제된 재생냉매가스는 비교적 높은 온도(40-60℃)에서 냉각기(6)로 압송 냉각되어진다.The regenerated refrigerant gas purified in the refining tank 3 is press-cooled to the cooler 6 at a relatively high temperature (40-60 ° C.).

이때 냉각기(6)에서 냉각되는 재생냉매가스의 온도가 일정 온도 이상되면 충전탱크(8')내에 저장을 할 수 없기 때문에 일정 온도 이상이 된 것을 감지밸브(6')가 감지하여 감지밸브(6')는 잠금하게 되고 동시에 우회관(4)에 설치된 감지밸브(9)(9')가 이를 신속히 파악하여 감지밸브(9)(9')를 열어주면 배출관(4')에서 정제탱크(3)내로 들어가는 냉매가스는 우회관(4)을 통해 정제탱크(3)와 콤프레셔(5) 사이에 있는 흡입관(4)으로 바이패스된다.At this time, when the temperature of the regeneration refrigerant gas cooled in the cooler 6 is above a certain temperature, the storage tank 8 'cannot be stored, so the detection valve 6' detects that the temperature is above a predetermined temperature and the detection valve 6 ') Is locked, and at the same time, the detection valves 9 and 9' installed in the bypass pipe 4 quickly detect this and open the detection valves 9 and 9 '. Refrigerant gas entering the c) is bypassed through the bypass pipe (4) to the suction pipe (4) between the purification tank (3) and the compressor (5).

이와 같이 바이패스 되면 우회관(4)에 있는 냉매가스는 정제탱크(3)내에서 흡인되는 정제가스와 혼합 냉각되어 콤프레셔(5)를 거쳐 배출관(4') 및 우회관(4)으로 압송되는 냉매가스의 온도가 낮아졌음을 감지밸브(9)(9')가 감지하여 감기밸브(6')에 알리므로 해서 감지밸브(6')가 열림됨에 따라 냉각기(6)는 다시 가동하고 냉각기(6)에서 냉각된 재생냉매가스는 휠터(7)에 의해 여과된 후 재생냉매가스충전탱크(8')내에 충전되는데 이때 충전량은 충전용량계(10')에 설정된 용량으로 자동 충전되며 이와 같이 충전된 탱크(8')를 차체의 폐냉매가스탱크(8)가 수거된 곳에 교체 설치하면 된다.When bypassed in this way, the refrigerant gas in the bypass pipe (4) is mixed and cooled with the purified gas drawn in the purification tank (3) and is pumped through the compressor (5) to the discharge pipe (4 ') and the bypass pipe (4). As the detection valve 6 'is opened by the detection valves 9 and 9' detecting that the temperature of the refrigerant gas is lowered and the winding valve 6 'is opened, the cooler 6 is restarted and the cooler ( The regenerated refrigerant gas cooled in 6) is filtered by the filter 7 and then charged into the regenerated refrigerant gas filling tank 8 '. At this time, the filling amount is automatically charged to the capacity set in the filling capacity meter 10'. The installed tank 8 'may be replaced with a place where the waste refrigerant gas tank 8 of the vehicle body is collected.

그리고 재처리하는 과정에서 흡입관(4)이나 배출관(4')의 연결이 불안전할때나 가스가 누설되면 이때에는 자동조절장치부(2)에 설치된 경보부자가 경보하게 되므로 이에 신속히 대처할 수 있는 것이다.And when the connection of the suction pipe (4) or the discharge pipe (4 ') in the process of reprocessing or when the gas leaks, the alarm rich installed in the automatic control device (2) at this time will be able to cope quickly.

즉 가동조절장치부(2)에 설치된 경보부자가 경보 신호하게 된다.That is, the alarm rich person installed in the movable control unit 2 is the alarm signal.

이상과 같이 본 고안은 몸체내에 폐냉매가스탱크(8)와 연결된 흡입관(4)의 일단을 정제탱크(3)에 연결하되 정제탱크(3), 콤프레셔(5), 냉각기(6), 휠터(7)등을 흡입관(4) 및 배출관(4')으로 연결하고 흡입관(4)과 배출관(4') 사이에는 우회관(4)을 설치하여 재생냉매가스의 온도와 압력을 감지하는 감지밸브(6')(9)(9')에 의해 재생냉매가스가 우회관(4)으로 바이패스되면서 온도와 압력을 자동식으로 조정하고 재생냉매가스충전탱크(8')에 임의량을 자동으로 충전할 수 있게 하였기 때문에 폐냉매가스 재활용으로 인한 환경공해 방지에 크게 기여할 수있는 것이다.As described above, the present invention connects one end of the suction pipe 4 connected to the waste refrigerant gas tank 8 to the purification tank 3, but the purification tank 3, the compressor 5, the cooler 6, the filter ( 7) a detection valve for connecting the lamp to the suction pipe 4 and the discharge pipe 4 'and installing a bypass pipe 4 between the suction pipe 4 and the discharge pipe 4' to sense the temperature and pressure of the refrigerating refrigerant gas ( 6 ') (9) (9') bypasses the regeneration refrigerant gas to the bypass pipe (4) and automatically adjusts the temperature and pressure to automatically fill the regeneration refrigerant gas filling tank (8 '). Because of this, it can greatly contribute to the prevention of environmental pollution by recycling waste refrigerant gas.
