Description
본 고안은 에어콘의 냉매순환라인에서 냉매를 회수한 후 수분과 불순물을 제거하는 등 재생한 후 다시 냉매순환라인으로 충전할 수 있도록 하는 에어콘 냉매 회수 재생 충전기의 냉매 회수 재생회로에 관한 것으로, 더 자세하게는 회수된 냉매의 재생과정에서 냉매가 액상으로 압축되는 것을 방지하여 압축기의 부하를 저감할 수 있도록 한 것에 관한 것이다.The present invention relates to a refrigerant recovery and regeneration circuit of an air conditioner refrigerant recovery and regeneration charger to recover the refrigerant in the refrigerant circulation line of the air conditioner, remove water and impurities, and then recharge the refrigerant circulation line. The present invention relates to reducing the load on the compressor by preventing the refrigerant from being compressed into the liquid phase during the regeneration of the recovered refrigerant.
일반적으로 실내공간의 온도를 조절할 수 있도록 하는 에어콘은 냉매가 증발기를 흐르는 사이 주변의 열을 빼앗으며 증발하게 되는 원리를 이용하는 것으로, 증발기를 통과한 냉매를 콤프레셔로 압축시켜 그 온도와 압력이 상승하게 되면 응축기에서 열을 방출시키고 팽창밸브를 통해 팽창시킨 후 다시 증발기로 공급하게 되는 냉매순환회로를 구비하게 되는 것이 보통이다.In general, the air conditioner that controls the temperature of the indoor space uses the principle that the refrigerant evaporates while taking away the heat around the evaporator, and compresses the refrigerant passing through the evaporator into a compressor to increase its temperature and pressure. In general, a refrigerant circulation circuit that discharges heat from the condenser, expands through the expansion valve, and supplies the evaporator is supplied again.
그런데 상기 냉매순환회로를 순환하는 냉매에 수분이나 불순물이 유입되거나 냉매의 양이 줄어들게 되면 냉각효율이 크게 저하될 뿐 아니라 각 구성부품이 부식되거나 손상될 우려가 많게 된다.However, when moisture or impurities are introduced into the refrigerant circulating through the refrigerant circulation circuit or the amount of the refrigerant is reduced, not only the cooling efficiency is greatly lowered, but also there is a possibility that each component is corroded or damaged.
본 고안이 관계하는 에어콘 냉매 회수 재생 충전기는 에어콘의 냉매순환회로로부터 냉매를 회수하여 수분과 각종 불순물을 제거한 후 다시 냉매순환회로에 충전할 수 있도록 하는 것으로, 재생한 냉매를 재충전하는 과정에서 부족한 냉매도 간편하게 보충할 수 있게 되는 것이다.The air conditioner refrigerant recovery regeneration charger according to the present invention recovers the refrigerant from the refrigerant circulation circuit of the air conditioner, removes moisture and various impurities, and then recharges the refrigerant circulation circuit. It will also be easy to replenish.
상기 에어콘 냉매 회수 재생 충전기는 냉매순환회로에 접속하여 냉매를 회수할 수 있도록 하고, 회수된 냉매를 순환시켜 재생할 수 있도록 하는 냉매 회수 재생회로를 구비하게 되며, 이 냉매 회수 재생회로는 냉매순환회로에 접속되어 냉매를 회수할 때 콤프레셔의 흡입력으로 흡입되는 냉매가 불순물제거필터를 거쳐 콤프레셔로 유입되도록 하는 동시에 오일/냉매분리기와 응축기, 제습필터를 경유하여 냉매용기에 저장되도록 하며, 회수된 냉매를 재생할 때에는 냉매용기에서 인출되는 냉매를 불순물제거필터 및 콤프레셔, 오일/냉매분리기, 응축기, 제습필터, 냉매용기의 경로로 일정횟수 순환시켜 냉매에 포함된 수분과 각종 이물질이 제거되도록 하는 것이 보통이다.The air conditioner refrigerant recovery and regeneration charger may include a refrigerant recovery and regeneration circuit connected to the refrigerant circulation circuit to recover the refrigerant and circulate and reclaim the recovered refrigerant. The refrigerant recovery and regeneration circuit may be connected to the refrigerant circulation circuit. When connected to recover the refrigerant, the refrigerant sucked by the suction power of the compressor is introduced into the compressor through the impurity removal filter, and stored in the refrigerant container via the oil / refrigerant separator, the condenser, and the dehumidification filter. At this time, it is common to circulate the refrigerant drawn out from the refrigerant container through the impurity removal filter, the compressor, the oil / refrigerant separator, the condenser, the dehumidification filter, and the refrigerant container a predetermined number of times to remove moisture and various foreign substances contained in the refrigerant.
그러나 도 2에 도시된 종래의 냉매 회수 재생회로는 회수된 냉매를 재생할 때에 냉매용기(17)로부터 인출되는 액체상태의 냉매가 콤프레셔(12)에 작용하기 때문에 콤프레셔(12)에 부하가 많이 걸리게 되어 냉매압축효율이 저하됨은 물론 콤프레셔(12)의 수명이 크게 단축되는 문제가 있었다.However, in the conventional refrigerant recovery / regeneration circuit shown in FIG. 2, since the refrigerant in the liquid state drawn out from the refrigerant container 17 acts on the compressor 12 when regenerating the recovered refrigerant, the compressor 12 is heavily loaded. As well as the refrigerant compression efficiency is lowered, there is a problem that the life of the compressor 12 is greatly shortened.
또한 종래의 냉매 회수 재생회로(10')는 콤프레셔(12)의 유입측 회수/재생유로(18)에 설치되는 불순물제거필터(11)를 통해 수분을 제거할 수 없었고 모든 수분의 제거는 응축기(14)와 냉매용기(17)의 사이의 회수/재생유로(18)에 설치되는 제습필터(15)를 통해 이루어졌기 때문에 수분제거효율이 나쁘게 되는 문제가 있었다.In addition, the conventional refrigerant recovery and regeneration circuit 10 ′ could not remove moisture through the impurity removal filter 11 installed in the inlet side recovery / regeneration flow path 18 of the compressor 12, and all moisture was removed from the condenser ( 14) and the dehumidification filter 15 installed in the recovery / regeneration flow path 18 between the refrigerant container 17, there was a problem that the water removal efficiency is bad.
한편 에어콘의 냉매순환회로에서 냉매를 모두 인출한 후에는 냉매순환회로에 잔류한 수분 및 불순물을 통해 제거할 필요가 있게 되는 바, 종래에는 냉매순환회로(10')에 진공펌프(30)를 접속하여 수분 및 불순물을 제거하였기 때문에 냉매 회수 재생 충전기와 별도로 진공펌프(30)를 구비하여야 하는 불편이 있었다.On the other hand, after the refrigerant is drawn out from the refrigerant circulation circuit of the air conditioner, it is necessary to remove the moisture and impurities remaining in the refrigerant circulation circuit. In the related art, the vacuum pump 30 is connected to the refrigerant circulation circuit 10 '. Since water and impurities were removed, the vacuum pump 30 had to be provided separately from the refrigerant recovery regeneration charger.
본 고안은 상기와 같은 종래의 냉매 회수 재생회로의 제결함을 감안하여 안출한 것이며, 그 목적이 회수된 냉매를 재생하는 과정에서 콤프레셔의 부하를 감소시킬 수 있도록 하는 에어콘 냉매 회수 재생 충전기의 냉매 회수 재생 회로를 제공하는 데에 있는 것이다.The present invention has been devised in view of the deficiencies of the conventional refrigerant recovery and regeneration circuit as described above, and the purpose is to recover the refrigerant in the air conditioner refrigerant recovery and regeneration charger to reduce the load on the compressor in the process of regenerating the recovered refrigerant. It is to provide a regeneration circuit.
아울러 본 고안은 그 다른 목적이 재생과정에서 냉매에 포함된 수분을 보다 효율적으로 제거할 수 있도록 하는 에어콘 냉매 회수 재생 충전기의 냉매 회수 재생 회로를 제공하는 데에 있는 것이며, 또 다른 목적이 별도의 진공펌프를 구비하지 않고서도 냉매순환회로의 수분과 이물질을 제거할 수 있도록 하는 에어콘 냉매 회수 재생 충전기의 냉매 회수 재생 회로를 제공하는 데에 있는 것이다.In addition, another object of the present invention is to provide a refrigerant recovery and regeneration circuit of an air conditioner refrigerant recovery and regeneration charger that can more efficiently remove moisture contained in the refrigerant during the regeneration process. It is an object of the present invention to provide a refrigerant recovery and regeneration circuit of an air conditioner refrigerant recovery and regeneration charger capable of removing moisture and foreign matter from a refrigerant circulation circuit without providing a pump.

본 고안은 상기의 목적을 달성하기 위하여 불순물제거필터 유입측의 회수/재생유로를 회수유로와 재생유로로 분리하여 서로 병렬로 연결하고 회수유로에 차단밸브를 설치하는 동시에 재생유로에 팽창밸브 및 증발기를 설치하여 압축될 냉매를 기화시킬 수 있도록 한 것과 불순물제거필터 내에 제습필터를 설치한 것, 그리고 오일/냉매분리기 유출측의 회수/재생유로에서 분기되는 진공배출유로를 마련한 것을 특징으로 하며, 이하 그 구체적인 기술내용을 첨부도면에 의거하여 더욱 자세히 설명하면 다음과 같다.In order to achieve the above object, the present invention separates the recovery / regeneration flow path at the inflow side of the impurity removal filter into the recovery flow path and the regeneration flow path, and connects them in parallel to each other, and installs a shutoff valve at the recovery flow path, and at the same time, an expansion valve and an evaporator And a dehumidification filter installed in the impurity removal filter, and a vacuum discharge flow passage branched from the recovery / regeneration flow path on the outflow side of the oil / coolant separator. The specific technical details will be described in more detail based on the accompanying drawings as follows.
즉, 도 1에는 본 고안의 냉매 회수 재생 회로도가 도시되어 있는 바, 본 고안은 불순물제거필터(11)와 콤프레셔(12), 오일/냉매분리기(13), 응축기(14), 제습필터(15), 냉매용기(17)가 회수/재생유로(18)를 통해 순차적으로 접속되고, 불순물제거필터(11) 유입측의 회수/재생유로(18)에 냉매순환회로(20)가 접속되는 에어콘냉매 회수 재생회로(10)를 구성함에 있어서, 상기 불순물제거필터(11) 유입측의 회수/재생유로(18)를 회수유로(18a)와 재생유로(18b)로 분리하여 서로 병렬로 연결하고 회수유로(18a)에 차단밸브(21)를 설치하는 동시에 재생유로(18b)에 팽창밸브(22) 및 증발기(23)를 설치하여서 되는 것이며, 아울러 불순물제거필터(11) 내부에 제습필터(11a)를 설치하고, 오일/냉매분리기(13)의 유출측 회수/재생유로(18)에 진공배출유로(19)를 분기 설치하여서 되는 것이다.That is, Figure 1 shows the refrigerant recovery and regeneration circuit diagram of the present invention, the present invention is the impurity removal filter 11 and the compressor 12, oil / refrigerant separator 13, condenser 14, dehumidification filter 15 And the refrigerant container 17 are sequentially connected through the recovery / regeneration flow path 18, and the air condition refrigerant to which the refrigerant circulation circuit 20 is connected to the recovery / regeneration flow path 18 on the inlet side of the impurity removal filter 11. In constructing the recovery and regeneration circuit 10, the recovery / regeneration channel 18 on the inlet side of the impurity removal filter 11 is separated into a recovery channel 18a and a recovery channel 18b and connected in parallel to each other. The isolation valve 21 is provided at 18a, and the expansion valve 22 and the evaporator 23 are provided at the regeneration flow path 18b, and the dehumidification filter 11a is installed inside the impurity removal filter 11. The vacuum discharge flow path 19 is branched on the outlet side recovery / regeneration flow path 18 of the oil / coolant separator 13.
도면부호중 미설명부호 16은 습도표시기, 24는 불순물 저장통, 25와 26은 냉매순환회로 차단밸브, 27은 냉매용기 유입측 차단밸브, 28은 냉매용기 유출측 차단밸브이다.In the drawings, reference numeral 16 denotes a humidity indicator, 24 an impurity reservoir, 25 and 26 are refrigerant circulation circuit shutoff valves, 27 is a refrigerant container inlet side shutoff valve, and 28 is a refrigerant container outlet side shutoff valve.
상기와 같이 구성된 본 고안에 있어서는 에어콘의 냉매순환회로(20)를 회수/재생유로(18)에 접속한 후 회수유로(18a)의 차단밸브(21)를 열어 놓은 상태에서 콤프레셔(12)를 작동시키게 되면 에어콘의 냉매가 회수유로(18a)를 통해 불순물제거필터(11)로 진입하게 되고, 콤프레셔(12)에서 압축된 후 오일/냉매분리기(13)와 응축기(14), 제습필터(16), 습도표시기(16)를 거쳐 냉매용기(17)에 충전된다.In the present invention configured as described above, after connecting the refrigerant circulation circuit 20 of the air conditioner to the recovery / regeneration channel 18, the compressor 12 is operated while the shutoff valve 21 of the recovery channel 18a is opened. In this case, the refrigerant of the air conditioner enters the impurity removal filter 11 through the recovery passage 18a, and is compressed in the compressor 12 and then the oil / refrigeration separator 13, the condenser 14, and the dehumidification filter 16. The refrigerant container 17 is charged via the humidity indicator 16.
그리고 에어콘의 냉매순환회로(20)에서 냉매를 완전히 회수한 후 회수된 냉매를 재생하고자 하는 때에는 냉매순환회로 차단밸브(25)(26)와 회수유로(18a)의 차단밸브(21)를 닫고, 냉매용기(17)의 유출측 차단밸브(28)를 연 다음 콤프레셔(12)를 작동시키게 되면 냉매용기(17)에 충전된 냉매가 재생유로(18b)의 팽창밸브(22) 및 증발기(23)를 경유하는 동안 기화되고 기화된 냉매는 콤프레셔(12)에서 압축된 후 오일/냉매분리기(13)와 응축기(14), 제습필터(16), 습도표시기(16)를 거쳐 다시 냉매용기(17)로 진입하게 되며, 냉매를 이와 같은 재생순환경로로 일정횟수 순환시키게 되면 불순물제거필터(11) 및 제습필터(16)를 통해 냉매에 포함된 수분 및 각종 불순물을 제거할 수 있게 된다.When the refrigerant is to be regenerated after the refrigerant is completely recovered from the refrigerant circulation circuit 20 of the air conditioner, the refrigerant circulation circuit shutoff valves 25 and 26 and the shutoff valve 21 of the recovery flow path 18a are closed. When the shutoff valve 28 of the refrigerant container 17 is opened and the compressor 12 is operated, the refrigerant charged in the refrigerant container 17 is expanded to the expansion valve 22 and the evaporator 23 of the regeneration flow path 18b. The vaporized and vaporized refrigerant during compression is compressed in the compressor (12) and then passed through the oil / refrigerant separator (13), the condenser (14), the dehumidification filter (16), and the humidity indicator (16). When the refrigerant is circulated a predetermined number of times in such a regeneration net environment, it is possible to remove moisture and various impurities included in the refrigerant through the impurity removal filter 11 and the dehumidification filter 16.
또한 본 고안에 있어서는 별도의 진공펌프(30) 없이도 냉매를 인출한 에어콘의 냉매순환회로를 청소할 수 있게 되는 바, 에어콘의 냉매순환회로(20)를 냉매 회수 재생회로(10)에 접속한 후 응축기 유입측 차단밸브(31)를 닫고 진공배출유로(19)의 차단밸브(32)를 연 다음 콤프레셔(12)를 일정시간동안 작동하게 되면 냉매순환회로(20)에 잔류하는 수분 및 각종 불순물을 제거할 수 있게 된다.In addition, in the present invention, it is possible to clean the refrigerant circulation circuit of the air conditioner withdrawing the refrigerant without a separate vacuum pump 30, and the condenser after connecting the refrigerant circulation circuit 20 of the air conditioner to the refrigerant recovery and regeneration circuit 10. Closing the inlet side shutoff valve 31 and opening the shutoff valve 32 of the vacuum discharge passage 19 and then operating the compressor 12 for a predetermined time removes moisture and various impurities remaining in the refrigerant circulation circuit 20. You can do it.
한편 본 고안에 있어서 냉매를 재생할 때에 작동되는 증발기(23)를 통해 작업공간이나 그 밖의 장소에 차가운 바람을 공급할 수 있게 되며, 냉매회수과정에서도 회수유로(18a)를 차단하고 재생유로(18b)로 냉매를 회수하여 차가운 바람을 공급할 수 있음은 물론이다.Meanwhile, in the present invention, the cooler can be supplied to the work space or other places through the evaporator 23 which is operated when the refrigerant is regenerated, and the recovery passage 18a is blocked and the regeneration passage 18b is blocked even in the refrigerant recovery process. Of course, the coolant can be supplied by recovering the coolant.
이상에서 설명한 바와 같이 본 고안은 불순물제거필터(11) 유입측의 회수/재생유로(18)를 회수유로(18a)와 재생유로(18b)로 분리하여 서로 병렬로 연결하고 회수유로(18a)에 차단밸브(21)를 설치하는 동시에 재생유로(18b)에 팽창밸브(22) 및 증발기(23)를 설치하는 한편, 불순물제거필터(11) 내부에 제습필터(11a)를 설치하고, 오일/냉매분리기(13)의 유출측 회수/재생유로(18)에 진공배출유로(19)를 분기 설치한 것으로, 본 고안에 의하면 회수된 냉매를 재생하는 과정에서 기화된 냉매를콤프레셔(12)로 공급할 수 있게 되므로 콤프레셔(12)의 부하를 대폭 저감할 수 있게 되어 압축효율을 크게 향상시킬 수 있게 됨은 물론 콤프레셔(12)의 수명을 연장할 수 있게 되는 효과를 얻을 수 있게 되며, 응축기(14)와 냉매용기(17) 사이의 제습필터(15)는 물론 불순물제거필터(11)에 내장된 제습필터(11a)를 통해 수분제거효율을 크게 향상시킬 수 있게 되는 효과를 얻을 수 있게 된다.As described above, the present invention separates the recovery / regeneration channel 18 on the inflow side of the impurity removal filter 11 into the recovery channel 18a and the regeneration channel 18b and connects them in parallel to each other. The expansion valve 22 and the evaporator 23 are installed in the regeneration flow path 18b at the same time as the shutoff valve 21 is installed, while the dehumidification filter 11a is installed inside the impurity removal filter 11, and the oil / refrigerant is installed. The vacuum discharge passage 19 is branched at the outlet side recovery / regeneration passage 18 of the separator 13, and according to the present invention, the refrigerant vaporized in the process of regenerating the recovered refrigerant can be supplied to the compressor 12. Since the load of the compressor 12 can be greatly reduced, the compression efficiency can be greatly improved, and the life of the compressor 12 can be extended, and the condenser 14 and the refrigerant can be obtained.
