Description
본 고안은 컴프레서의 냉동유를 자동으로 충진시키는 장치에 관한 것으로, 특히 컴프레서의 작동중 내부의 이상고압현상으로 인해 외부로 배출되는 냉동유의 부족분에 대한 보충이 자동적으로 이루어질 수 있게 하여 컴프레서의 동작중 고착을 방지하면서 내구성능을 향상시킬 수 있도록 된 컴프레서의 냉동유 자동충진장치에 관한 것이다.The present invention relates to a device for automatically filling the refrigeration oil of the compressor, in particular during the operation of the compressor to make up for the shortage of the refrigeration oil discharged to the outside due to the abnormal high-pressure phenomenon inside. The present invention relates to a refrigeration oil automatic filling device of a compressor that can improve durability while preventing sticking.
일반적으로 자동차에 탑재된 냉방장치는 하절기와 같이 차실내의 온도가 상승할 경우에도 탑승한 승객의 쾌적함을 유지시키기 위한 목적으로 장착된 것인 바, 이러한 목적으로 장착되는 냉방장치는 대개 액체가 증발하면서 주위의 열을 흡수하는 현상을 이용한 것이고, 또한 제습과 공기여과기를 두어 실내 공기속에 포함된 먼지도 제거하도록 되어 있다.In general, air conditioners mounted on automobiles are installed for the purpose of maintaining the comfort of passengers on board even when the temperature inside the cabin rises, such as in summer. It uses the phenomenon of absorbing the surrounding heat while also dehumidifying and air filter to remove the dust contained in the indoor air.
상기와 같은 냉방장치는 냉매를 고온, 고압의 가스상태로 압축하는 컴프레서와, 팽창밸브로부터 공급된 냉매가 주위의 열을 흡수하면서 증발하는 증발기, 이 증발기에서 흡수한 열을 외부의 공기로 냉각되면서 방출하여 냉매가 액화상태로 되는 응축기, 이 응축기에서 열을 발산하여 액체로 된 냉매가 바로 팽창 밸브로 유입되지 않고 일시적으로 저장되도록 하는 리시이버 및, 차실내의 공기를 상기 증발기로 보내 열교환을 하게 하면서 차실내로 찬바람을 보내는 송풍기 등을 갖춘 구조로 되어 있다.The cooling device as described above includes a compressor for compressing a refrigerant into a high-temperature, high-pressure gas state, an evaporator in which the refrigerant supplied from the expansion valve evaporates while absorbing the surrounding heat, and the heat absorbed by the evaporator is cooled by external air. A condenser that discharges the refrigerant into a liquefied state, emits heat from the condenser, and allows the liquid refrigerant to be temporarily stored instead of directly entering the expansion valve, and sends air in the cabin to the evaporator for heat exchange. It has a structure such as a blower that sends a cold wind into the interior of the car.
그런데 상기와 같은 냉방장치중 컴프레서(11)는 제1도에 도시된 바와 같이, 몸체(12)의 일측부에 릴리프밸브(13)를 갖추고 있어 이 컴프레서(11)의 작동중 내부가 이상고압으로 될 경우에는 내부의 냉매와 냉동유가 상기 릴리프밸브(13)를 통해 외부로 동시에 배출되도록 되어 있다.However, as shown in FIG. 1, the compressor 11 of the above-mentioned cooling apparatus includes a relief valve 13 at one side of the body 12, and the inside of the compressor 11 is operated at abnormal high pressure. If so, the refrigerant inside and the refrigeration oil are simultaneously discharged to the outside through the relief valve (13).
따라서 상기와 같이 컴프레서(11)의 내부가 잦은 이상고온으로 인해 릴리프밸브(13)를 통한 내부의 냉매와 냉동유가 빈번히 배출되게 되면, 이 컴프레서(11)의 작동에 필요한 냉동유의 절대량이 부족하게 되고, 이는 컴프레서(11)의 고착현상을 초래하여 냉방이 원활히 일루어짐은 물론 컴프레서(11)의 파손까지도 초래할 수 있는 단점이 있었다.Therefore, when the inside of the compressor 11 is frequently discharged from the refrigerant and the refrigerant through the relief valve 13 due to the abnormal high temperature, the absolute amount of the refrigerant required for the operation of the compressor 11 is insufficient. , This causes the sticking phenomenon of the compressor (11) has a disadvantage that not only cooling is smoothly performed but also damage to the compressor (11).
이에 본 고안은 상기와 같은 점을 감안하여 안출된 것으로, 냉방장치의 가동시 컴프레서내의 이상고압현상으로 인해 냉동유가 릴리프밸브를 통해 외부로 배출됨에 따른 냉동유의 부족분이 컴프레서의 몸체상에 저장된 예비 냉동유를 컴프레서내로 자동으로 보충될 수 있게 하여 컴프레서의 동작중 고착을 방지하면서 내구성능을 향상시킬 수 있도록 된 컴프레서의 냉동유 자동충진장치를 제공함에 그 목적이 있다.The present invention has been devised in view of the above, and the preliminary freezing stored in the body of the compressor due to the shortage of the freezing oil is discharged to the outside through the relief valve due to the abnormal high-pressure phenomenon in the compressor during operation of the cooling device It is an object of the present invention to provide a refrigeration oil automatic filling device of the compressor which can improve the durability while preventing oil from being fixed during operation of the compressor by automatically replenishing the oil into the compressor.

또한 상기 엔진제어유니트(6)는 컴프레서(1)내의 이상고온으로 릴리프밸브(3)를 통해 수거통(4)내로 배출된 냉동유의 포집량을 감지하는 위치센서(5)로부터 신호받도록 되어, 이 수거통(4)내에 모인 냉동유의 양이 일정수준을 넘으면 상기 몸체(2)와 연통된 보조저장조(9)의 개구부(7)를 막고 있던 솔레노이드밸브(10)를 개방시켜 이 보조저장조(9)의 내부에 저장하고 있던 예비 냉동유(8)를 컴프레서(1)의 몸체(2)내부로 유입되도록 해 준다.In addition, the engine control unit 6 is to receive a signal from the position sensor (5) for detecting the collection amount of the refrigerant oil discharged into the container (4) through the relief valve (3) at the abnormal high temperature in the compressor (1), this container If the amount of the refrigerating oil gathered in (4) exceeds a predetermined level, the solenoid valve 10 that is blocking the opening 7 of the auxiliary reservoir 9 in communication with the body 2 is opened to open the interior of the auxiliary reservoir 9. The preliminary freezing oil (8) stored in the inlet is allowed to flow into the body (2) of the compressor (1).
따라서 상기와 같이 구성된 본 고안의 컴프레서의 냉동유 자동충진장치는, 상기 컴프레서(1)내의 이상고온으로 인해 냉매와 냉동유가 릴리프밸브(3)를 통해 수거통(4)내로 배출되면, 이 수거통(4)에서는 상부의 개구부(11)를 통해 냉매만을 증발시키고 수거통(4)내로는 냉동유만을 포집하게 되는데, 이때 수거통(4)내의 위치센서(5)는 포집되는 냉동유만을 포집하게 되는데, 이때 수거통(4)내의 위치센서(5)는 포집되는 냉동유의 양을 엔진제어유니트(6)로 신호보내게 되고, 이 신호를 받은 엔진제어유니트(6)에서는 수거통(4)내에 모인 냉동유의 양이 일정수준을 넘어 컴프레서(1)내에 냉동유의 부족상태를 감지하면 상기 몸체(2)와 연통된 보조저장조(9)의 개구부(7)를 개방시키도록 개구부(7)를 막고 있던 솔레노이드밸브(10)를 작동시켜 보조저장조(9)의 내부에 저장된 예비 냉동유(8)를 몸체(2)내부로 유입시켜 컴프레서(1)의 정상동작에 기여할 수 있게 된다.Therefore, the automatic refrigeration oil filling device of the compressor of the present invention configured as described above, when the refrigerant and the refrigeration oil is discharged into the container 4 through the relief valve 3 due to the abnormal high temperature in the compressor (1), this container (4) In the evaporation of only the refrigerant through the upper opening 11 and collecting only the refrigeration oil into the sump (4), the position sensor (5) in the sump (4) is to collect only the frozen oil is collected, in this case The position sensor 5 in (4) signals the amount of refrigeration oil collected to the engine control unit 6, and in the engine control unit 6 having received this signal, the amount of the refrigeration oil gathered in the container 4 is constant. When the low level of the refrigeration oil is detected in the compressor 1 beyond the level, the solenoid valve 10 which is blocking the opening 7 is opened to open the opening 7 of the auxiliary reservoir 9 in communication with the body 2.
