본 발명은 자동차 에어컨 시스템에 관한 것으로, 특히, 시동상태에서 에어컨 시스템을 흐르는 냉매의 누출을 감지하여 에어컨의 시스켐의 고장을 미연에 방지 보호할 수 있도록 한 자동차 에어컨의 냉매누출 감지장치에 관한 것이다. 일반적으로 종래의 자동차는 제1도에서와 같은 에어컨 시스템으로 운영되고 있는데, 이러한 종래의 에어컨 시스템은 라디에이터 전방에 설치되어 자동차의 속도와 냉각팬에 의해 고온고압 기체 상태의 냉매를 응축시켜 고온고압의 액상탱매로 만드는 응축기(140)와 냉매속에 포함되어 있는 수분을 흡수하여 냉매를 원활하게 공급할 수 있도록 냉매를 저장하는 리시버드라이어(120)와, 냉매를 급속 팽창시켜 저온저압액이 되게 하는 팽창밸브와, 안개 상태의 냉매가 기체로 변하는 동안 냉각팬의 작동으로 통과하는 공기중의 열을 빼앗는 에버퍼레이트와, 엔진에 의해 V벨트로 구동 되어지며 저온저압의 가스냉매를 고온고압의 가스로 만들어 상기 응축기(140)에 보내는 컴프레서(160)로 구성된다. 그런데 이렇게 구성되는 종래의 에어컨 시스템은 냉매의 유·무를 확인할 경우 에어컨을 가동시킨 다음 일정한 시간이 지난후에 냉매의 유·무를 확인할 수 있는 것으로 이러한 경우 엔진 후드를 개방하여 리시버사이트 글래스를 관찰하여 냉매의 유·무를 확인하여야 하는 확인작업의 곤란성이 있어 매우 불편한 문제점이 있었다. 더 구체적으로 설명하면 종래 자동차의 에어컨 시스템으로는 별도로 냉매의 누출을 감지할 수 있는 장치가 설치되어 있지 않아 운전자가 에어컨 냉매의 유·무를 확인할 수 없기 때문에 냉매의 누출로 인한 냉매의 부족으로 에어컨의 가동시 에어컨 시스템에 무리가 가해지게 되어 에어컨 시스템이 손상되어 에어컨 시스템을 정비업소에서 수리를 해야하는 비경제적인 문제점도 발생한다.The present invention relates to an automotive air conditioner system, and more particularly, to a refrigerant leak detection apparatus for an automotive air conditioner that detects a leak of a refrigerant flowing through an air conditioner system in a startup state to prevent failure of a system air conditioner in advance. . In general, a conventional car is operated with the air conditioner system as shown in FIG. 1, which is installed in front of the radiator to condense the refrigerant in the high-temperature and high-pressure gas state by the speed of the car and the cooling fan. A condenser 140 made of a liquid tank and a receiver dryer 120 storing a refrigerant so as to absorb moisture contained in the refrigerant to smoothly supply the refrigerant, and an expansion valve for rapidly expanding the refrigerant to become a low temperature low pressure liquid; It is driven by the V-belt by the engine and the Everperate which takes away the heat in the air passing through the operation of the cooling fan while the refrigerant in the fog state is turned into a gas, Compressor 160 sent to condenser 140. However, the conventional air conditioner system configured as described above can check the presence or absence of the refrigerant after a predetermined time after the air conditioner is operated. In this case, the engine hood is opened to observe the receiver site glass to determine the refrigerant. There was a very uncomfortable problem due to the difficulty of the verification work to confirm the presence or absence. More specifically, the conventional air conditioner system of the vehicle is not equipped with a separate device for detecting the leak of the refrigerant, the driver can not determine the presence or absence of the air conditioner refrigerant, so the lack of refrigerant due to the refrigerant leak of the air conditioner When the air conditioner system is put into operation, the air conditioner system is damaged and the air conditioner system needs to be repaired at the repair shop.
