본 고안은 자동차 에어콘 압축기에 사용되는 프레온 가스의 회수, 재생, 세척, 충전 장치에 관한 것이다.The present invention relates to a device for recovering, regenerating, washing and filling a freon gas used in an automobile air conditioner compressor.

종래에는 자동차 에어콘의 냉매 프레온 가스를 교체 사용할때 에어콘 압축기에 잔류되어 있는 기존 냉매유와 보충되는 새로운 냉매유와의 혼합 사용이 불가능하므로 잔류되어 있는 냉매유를 깨끗이 제거하고, 새로운 프레온가스를 충전해야 하므로 자동차내의 압축기를 분리한 다음 이를 분해, 세척한후 압축기를 결합해야 하므로, 프레온가스를 충전시키기 위하여 많은 작업 시간이 필요하게 되는 문제점이 있었다.Conventionally, when the refrigerant air of the vehicle air conditioner is used to replace the refrigerant, the existing refrigerant oil remaining in the air conditioner and the new refrigerant oil to be replenished cannot be used. Therefore, the remaining refrigerant oil must be removed and the new freon gas must be filled. Therefore, to separate the compressor in the car and then to disassemble and wash it, the compressor must be combined, there was a problem that requires a lot of work time to fill the Freon gas.

본 고안은 이러한 문제점을 해소하기 의하여 안출된 것으로서, 기존의 자동차 에어콘 압축기를 분리하지 않고 에어콘 저압 밸브와 본 고안의 취출라인 사이에 게이지 매니홀드(Gauge Manifold)를 연결시켜, 전기적 작동으로 여과기측과 수분 및 산분제거기측 전자변을 개방하면 기존의 냉매가 여과기 → 1차기름분리기 → 압력제어기 → 1차수분 및 산분제거기 → 회수재생용압축기 → 압축후 냉매와 기름분리기 → 저장탱크 순서로 응축된 냉매가 저장되고, 압축후 냉매와 기름분리기에서 나온 일부분 응축냉매는 응축기에서 응축되고 1차 기름분리기에 부착된 열교환기를 통하여 2차 수분 및 산분제거기를 통과한 후 냉매 흐름관측구를 지나 저장탱크에 저장되도록 된 것으로서 기존의 냉매를 회수, 재생, 세척을 동시에 한 시스템으로 하고, 재생될 냉매를 재사용할 수 있도록 고안된 것이다.The present invention has been devised to solve this problem, and the gauge manifold is connected between the air conditioner low pressure valve and the drawing line of the present invention without separating the existing automobile air conditioner compressor. When the electronic valve is opened on the water and acid remover side, the existing refrigerant is filtered → primary oil separator → pressure controller → primary water and acid remover → recovery and regeneration compressor → compressed and refrigerant and oil separator → storage tank Partial condensation refrigerant from the refrigerant and the oil separator after compression is condensed in the condenser and passed through the secondary water and acid deaerator through the heat exchanger attached to the primary oil separator, and then stored in the storage tank through the refrigerant flow observation port. It is possible to recover, regenerate, and wash existing refrigerants simultaneously. It is designed to be reused.

Connected to the refrigerant (9) to draw in,

1차기름분리기(4)와 솔레노이드밸브(2b)사이에는 솔레노이드밸브(2d)와 진공펌프(15)가 분배 설치되고, 취출라인(1) 일측 솔레노이드밸브(2a)라인 일측에 수동조작밸브(18)와 (18a)을 갖은 새냉매저장용기(16)와 세정액용기(17)가 구비되고, 1차 기름분리기(4) 저부에는 수동밸브(18b)을 갖은 기름용기(19)가 설치된 구성이다.A solenoid valve (2d) and a vacuum pump (15) are distributed and installed between the primary oil separator (4) and the solenoid valve (2b), and a manual override valve (18) is provided at one side of the solenoid valve (2a) line on the outlet line (1). ) And a fresh refrigerant storage container (16) having a) and (18a) and a cleaning liquid container (17), and an oil container (19) having a manual valve (18b) is installed at the bottom of the primary oil separator (4).

미설명부호 20은 게이지매니홀드이며, 21은 회로내의 고압과 저압을 제어하는 제어기이다.Reference numeral 20 is a gauge manifold, and 21 is a controller for controlling the high and low pressures in the circuit.

이와 같이 구성된 본 고안은 제1도의 설치 구성도와 같이 자동차 에어콘 압축기 저압밸브(도시없음)와 취출라인(1) 사이에 게이지매니홀드(20)를 연결시켜 별도의 솔레노이드밸브조작 콘트롤부를 작동시켜 솔레노이드밸브(2a)(2c)(2d)가 잠긴 상태에서 솔레노이드밸브(2)와 (2b)를 개방시키면 자동차에어콘 압축기 냉매는 불순물여과기(3)를 지나 1차 기름분리기(4)에서 냉매와 기름을 분리시켜 기름은 남고 냉매는 압력제어기(5)를 통하여 수분 및 산분제거(6)에 인입되어 수분과 산분이 제거된 후 회수 재생용압축기(7)에서 압축된 후, 다시 2차냉매 및 기름분리기(8)에서 기름과 냉매가 분리되고, 압축냉매는 저장탱크(9)에 저장되고, 일부 공기를 동반한 냉매는 2차응축기(12)에 인입되어 공기는 공기방출구(14)에 의하여 외부로 유출되고, 순수압축냉매와 저장탱크(9)에 다시 저장된다.According to the present invention, the solenoid valve is operated by connecting a gauge manifold 20 between the automobile air conditioner compressor low pressure valve (not shown) and the blowout line 1 as shown in FIG. If the solenoid valves (2) and (2b) are opened while the (2a), (2c) and (2d) are locked, the air conditioner compressor refrigerant passes the impurity filter (3) and separates the refrigerant and oil from the primary oil separator (4). After the oil is left and the refrigerant is introduced into the water and acid removal (6) through the pressure controller (5), the water and acid are removed and then compressed in the recovery and regeneration compressor (7), and then the secondary refrigerant and oil separator ( 8) oil and refrigerant are separated, the compressed refrigerant is stored in the storage tank (9), the refrigerant with some air is introduced into the secondary condenser 12, the air is discharged to the outside by the air outlet (14) Pure refrigerant and storage tanks Is stored back in (9).

또한, 압축후 발생한 기름과 냉매를 분리시킨 냉매의 일부가 응축기(10)에서 불응축된 것은 솔레노이드밸브조작 콘트롤부(도시없음)에서 솔레노이드밸브(2)를 잠그고 슬레노이드밸브(2c)를 개구시키면 냉매는 연교환기를 통과한후 수분 및 산분제거기(6')에서 다시 여과된 후 냉매온도제어기(13)을 지나 공기방출구(14)를 갖은 2차응축기(12) 외주면 열교환기를 통과하면서 저압으로 변한뒤 솔레노이드밸브(2c)를 거쳐 1차 기름분리기(4)에 재인입되어 재생 과정을 반복하고 재생된 냉매는 냉매흐름관측구(11) 라인과 2차기름 및 냉매분리기(8) 일측 라인을 통하여 저장탱크(9)에 저장된다.In addition, a portion of the refrigerant separating the oil and the refrigerant generated after compression is not condensed in the condenser 10 because the solenoid valve 2 is closed in the solenoid valve operation control unit (not shown) and the snoroid valve 2c is opened. After passing through the soft exchanger, the refrigerant is filtered again by the moisture and acid desorber (6 '), and then passes through the refrigerant temperature controller (13) to pass through the heat exchanger on the outer circumferential surface of the secondary condenser (12) having an air outlet (14) to change to low pressure. After reentering the primary oil separator (4) through the solenoid valve (2c) and repeating the regeneration process, the regenerated refrigerant flows through the refrigerant flow port (11) line, the secondary oil and the refrigerant separator (1) line. It is stored in the storage tank (9).

이 과정에서 저장탱크(9)에 유입되는 냉매의 응축 상태를 냉매흐름관측구(11)를 통하여 관찰할 수 있으며 냉매의 재생압력 상태는 압력제어기(5)에서 계기로 확인된다.In this process, the condensation state of the refrigerant flowing into the storage tank 9 can be observed through the refrigerant flow observation port 11, and the regeneration pressure state of the refrigerant is confirmed by the instrument in the pressure controller 5.

이렇게 냉매를 재생시킨후 솔레노이드밸브(2)와 (2d)을 개구시키고, 솔레노이드밸브(2c)(2d)를 닫은후 자동자에어콘 내부를 진공펌프(15)로 진공시킨후 솔레노이드밸브(2)와 (2d)를 닫고 솔레노이드밸브(2a)와 수동밸브(18a)를 개구시키면 세정액용기(17)내의 세척용 세정액은 자동차에어콘 내부가 진공된 상태이므로 사이펀 원리에 의하여 투입시킨후. 슬레노이드밸브(2a)와 수동밸브(18a)을 닫고 솔레노이드밸브(2)와 (2d)을 열어서 진공펌프(15) 가동시켜 세정액을 흡입시켜 에어콘 내부를 세척하게 된다.After the refrigerant is regenerated, the solenoid valves 2 and 2d are opened, the solenoid valves 2c and 2d are closed, and the inside of the air conditioner is vacuumed with a vacuum pump 15, and the solenoid valves 2 and ( If 2d) is closed and the solenoid valve 2a and the manual valve 18a are opened, the cleaning liquid for cleaning in the cleaning liquid container 17 is vacuumed inside the vehicle air conditioner, and then the siphon principle is introduced. The solenoid valve 2a and the manual valve 18a are closed and the solenoid valves 2 and 2d are opened to operate the vacuum pump 15 to suck the cleaning liquid to clean the inside of the air conditioner.

이렇게 세척시킨후 자동차 에어콘내에 새로운 냉매가스를 주입시에도 세척과정과 같은 방법으로 솔레노이드밸브(2)와 (2d)를 개구시켜 진공펌프(15)로 진공시킨후 솔레노이드밸브(2)와 (2d)를 다시 닫고, 솔레노이드밸브(2a)와 수동밸브(18)을 개구시키면 냉매가 저장된 용기(16)내의 새로운 냉매가 사이펀 원리에 의하여 에어콘에 충전되게 된 것이다.After the washing, the solenoid valve (2) and (2d) are opened and vacuumed by the vacuum pump (15) in the same manner as the washing process, even when the new refrigerant gas is injected into the air conditioner of the vehicle. The solenoid valve (2) and (2d) When the valve is closed again and the solenoid valve 2a and the manual valve 18 are opened, the new refrigerant in the container 16 in which the refrigerant is stored is filled in the air conditioner by the siphon principle.

또한, 저장탱크(9)내의 저장된 재생 냉매 가스액을 별도의 장치(도시없음)에 의해 냉매저장용기(16)로 재충전 사용하여 재생된 잔류 냉매를 다시 사용할 수 있게 된 것이다.In addition, the residual refrigerant regenerated by recharging the regenerated refrigerant gas liquid stored in the storage tank 9 into the refrigerant storage container 16 by a separate device (not shown) can be used again.

이렇게 된 본 고안을 자동차의 에어콘 냉매 교환시 잔류 냉매를 재생시켜 회수하여 재사용하고. 에어콘 압축기의 세척 및 냉매충진을 본 고안의 시스템으로 간단 용이하게 하므로서 프레온가스 교체작업 시간을 단축시킬수 있게 된 효과를 갖게 되었다.The present invention is recovered and reused by regenerating the residual refrigerant when the air conditioner refrigerant exchange of the vehicle. By simply and easily cleaning the air conditioning compressor and the refrigerant filling system of the present invention has the effect that can shorten the operation time of freon gas replacement.
