Description
본 발명은 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 에어콘의 냉매순환라인에서 냉매를 회수할 때에 냉매용기의 압력이 과도하게 높아지는 것을 방지할 수 있도록 하는 한편 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 moisture and impurities, and then recharge the refrigerant circulation line. When the refrigerant is recovered in the refrigerant circulation line of the air conditioner, the pressure of the refrigerant container can be prevented from being excessively increased, and the compressor load can be reduced by preventing the refrigerant from being compressed into the liquid phase during the recovery of the recovered refrigerant. It's about what you do.
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 구비하는 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 then supplies it back to the evaporator.
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 발명이 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 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 콤프레셔(12)를 통해 고압으로 압축되는 냉매가 오일/냉매분리기(13)와 응축기(14), 제습필터(15)를 경유하여 냉매용기(17)로 회수되는 냉매 회수과정에서 냉매가 하나의 응축기(14)만을 거치게 되어 냉매의 압력을 충분히 저감시킬 수 없게 되므로 냉매용기(17)에 과도한 압력이 걸리게 됨은 물론 압축기(12)의 후방압력이 높게 되어 비교적 냉매 회수시간이 많이 소요되는 문제가 있었을 뿐 아니라 냉매용기(17)로 회수된 냉매가 외부로 유출될 우려가 많게 되는 문제가 있었다.However, in the conventional refrigerant recovery / regeneration circuit illustrated in FIG. 2, the refrigerant compressed to high pressure through the compressor 12 passes through the oil / coolant separator 13, the condenser 14, and the dehumidification filter 15. In the process of recovering the refrigerant, the refrigerant passes through only one condenser 14, so that the pressure of the refrigerant cannot be sufficiently reduced, so that excessive pressure is applied to the refrigerant container 17 and the rear pressure of the compressor 12 is high. Therefore, there was a problem that a relatively long time to recover the refrigerant, as well as a problem that the refrigerant recovered in the refrigerant container 17 is likely to leak to the outside.
본 발명은 상기와 같은 종래의 냉매 회수 재생회로의 제결함을 감안하여 안출한 것이며, 그 목적이 냉매를 회수하는 과정에서 냉매용기에 과도한 압력이 걸리는 것을 방지할 수 있도록 하는 에어콘 냉매 회수 재생 충전기의 냉매 회수 재생회로를 제공하는 데에 있는 것이다.The present invention has been made in view of the deficiencies of the conventional refrigerant recovery and regeneration circuit as described above, and an object thereof is to provide an air conditioner refrigerant recovery and regeneration charger for preventing excessive pressure from the refrigerant container during the recovery of the refrigerant. It is to provide a refrigerant recovery regeneration circuit.
