본 고안의 자동차용 에어컨시스템의 안전장치에 관한 것으로서 더욱 상세하게는 컴프레셔로 유입되는 냉매를 감지하여 냉매의 상태에 따라 컴프레셔의 자동방식을 변경할 수 있도록 한 것이다.The present invention relates to a safety device for an air conditioner system for a vehicle, and more particularly, to detect a refrigerant flowing into a compressor and to change an automatic method of the compressor according to the state of the refrigerant.

자동차의 공조장치는 주위의 각종변화에 따른 온도 및 습도와 공기의 환경을 적절하게 유지시켜 승차자에게 쾌적함을 주기위한 것으로서 블로워팬에 의하여 유입된 공기를 냉각시켜 차가운 공기를 공급하여 주는 증발기와 가열하여 더운공기를 공급하여주는 히터코어로 크게 구성이 된다.The air conditioner of the car is to keep the temperature, humidity and the air environment according to various changes of the surroundings appropriately to give the passengers comfort.It is heated by an evaporator that cools the air introduced by the blower fan and supplies cold air. It is largely composed of a heater core that supplies hot air.

상기와 같은 공조장치의 에어컨시스템(15)은 제 1 도에 도시된 바와 같이 컴프레셔(10), 컨덴서(11), 리시버드라이어(12), 팽창밸브(13) 및 증발기(14)로 구성되어 진다.The air conditioner system 15 of the above air conditioner is composed of a compressor 10, a condenser 11, a receiver dryer 12, an expansion valve 13 and an evaporator 14 as shown in FIG. .

상기 컴프레셔는 엔진에 의하여 구동하면서 증발기에서 저압기체화된 냉매를 상온에서도 액화될 수 있도록 합축하여주는 역할을 하며, 컨덴서는 컴프레셔에서 압축된 냉매를 공급받아 기체화된 냉매의 열을 대기로 방출시켜 액화상태로 만들게 된다.The compressor serves to condense the low-pressure gasified refrigerant in the evaporator to be liquefied at room temperature while being driven by the engine, and the condenser receives the compressed refrigerant from the compressor to discharge heat of the gasified refrigerant into the atmosphere. To make it liquefied.

상기 리시버드라이어는 컨덴서에서 액화된 냉매를 공급받아 냉매속에 함유된 수분을 흡수하는 역할을 수행하며, 리시버드라이어를 거친 냉매는 팽창밸브로 유입되어 증발이 쉬운 저압의 상태로 감압하여 냉매를 증발기로 보내고, 증발에 공급된 냉매는 블로워팬이 불어내는 공기가 지나가면서 냉매의 열원을 빼앗아 가게 됨으로서 자동차의 실내로 유입되는 공기는 차가운 상태로 되는 것이다.The receiver dryer receives the liquefied refrigerant from the condenser and absorbs the moisture contained in the refrigerant. The refrigerant passed through the receiver dryer flows into the expansion valve to reduce the pressure to a low pressure that is easy to evaporate, and sends the refrigerant to the evaporator. In addition, the refrigerant supplied to the evaporation takes away the heat source of the refrigerant as the air blown by the blower fan passes, and the air flowing into the interior of the vehicle becomes cold.

그리고, 증발기에서 열원을 빼앗긴 냉매는 액체상태로 되어 다시 컴프레셔로 보내어지는 순환작용을 하는 것이다.In addition, the refrigerant deprived of the heat source from the evaporator is in a liquid state and performs a circulating action sent back to the compressor.

상기와 같은 종래의 에어컨시스템에는 증발기에서 액화된 냉매가 유입되는 컴프레셔측에 유입되는 냉매의 압력과 온도를 감지할 수 있는 장치가 없는 관계로 외기가 낮거나 습도가 많은 경우에는 기체상태의 냉매가 컴프레셔로 유입되어야 함에도 불구하고 액체상태의 냉매가 많이 발생하게 된다.In the conventional air conditioner system as described above, since there is no device capable of detecting the pressure and temperature of the refrigerant flowing into the compressor side into which the refrigerant liquefied from the evaporator flows, when the outside air is low or the humidity is high, the gaseous refrigerant is Despite the flow into the compressor, a lot of refrigerant in the liquid state is generated.

이러한 경우에는 컴프레셔의 내구성이 약화되고 심화될 경우에는 컴프레셔의 파손을 야기할 수 있게되며 이러한 경우에는 에어컨시스템의 막대한 악영향을 미치게 되는 것이다.In this case, if the durability of the compressor is weakened and deepened, it may cause damage to the compressor. In this case, the air conditioner system has a huge adverse effect.

이에 본 고안에서는 상기한 문제점들을 해결하기 위하여 안출이 된것으로서 컴프레셔로 유입되는 유입구 위치에 증발기에서 유입되는 냉매의 온도와 압력을 감지할 수 있는 수단을 강구하여 이상저온 및 이상저압일 때 공기유입경로를 바꾸도록 한 것이 특징이다.In this invention, in order to solve the above problems, the air inflow path at the time of abnormal low temperature and abnormal low pressure by taking a means for detecting the temperature and pressure of the refrigerant flowing from the evaporator at the inlet position of the compressor. It is characterized by changing the.
