본 발명은 버스차량 등의 지붕에 증발기 유닛과 콘덴서 유닛을 설치하고 이들을 차량의 후방 엔진룸에 설치되는 압축기와 연결관으로 각각 연결하도록 한 에어컨에있어서, 상기 버스차량의 지붕에 설치되는 증발기 유닛과 콘덴서 유닛 및 압축기의 연결관 부위에 각각의 감지센서들을 설치하고 이들 감지센서의 신호에 따라 냉매의 유출을 확인할 수 있도록 한 차량의 지붕장착용 에어컨장치에 관한 것이다.The present invention provides an air conditioner in which an evaporator unit and a condenser unit are installed on a roof of a bus vehicle, and the like are connected to a compressor and a connection pipe respectively installed in a rear engine room of the vehicle. The present invention relates to an air conditioner for roof mounting of a vehicle, in which respective detection sensors are installed at a condenser unit and a connection part of a compressor, and the leak of refrigerant can be checked according to the signals of the detection sensors.

종래 일반적인 다인승용 버스등에는 도 1에서와 같이 차량 내부의 냉방을 위하여 냉방장치인 에어컨을 구비하고 있으며, 이 에어컨은 차량의 엔진에 연결되어 구동되는 압축기(2)를 차량의 엔진부에 설치하고, 차량의 지붕(1)에는 상기 압축기(2)와 연결되는 콘덴서 유닛(3)과 증발기 유닛(4)을 탑재하는 형태로 설치하고 있었으며, 상기 콘덴서와 증발기 유닛(3)(4)은 차량의 지붕(1) 전체적인 면적을 차지하면서 지붕(1)에서 돌출되는 상태로 설치되어 있었고 상기 압축기와 콘덴서 및 증발기 유닛들은 서로 연결관으로 연결되어 냉매가 순환하면서 열교환 작용을 하도록 되어 있었다.The conventional multi-seat bus, etc. is provided with an air conditioner that is a cooling device for cooling the interior of the vehicle, as shown in Figure 1, this air conditioner is installed in the engine unit of the vehicle and the compressor (2) connected to the engine of the vehicle and driven On the roof 1 of the vehicle, a condenser unit 3 and an evaporator unit 4 connected to the compressor 2 are mounted. The condenser and the evaporator unit 3 and 4 are mounted on the vehicle roof. The roof 1 was installed to protrude from the roof 1 while occupying the entire area, and the compressor, the condenser, and the evaporator units were connected to each other by connecting pipes, and the refrigerant was circulated to exchange heat.

그러나, 상기와 같은 종래의 것은 상기 압축기에서 압축된 냉매를 응축시키는 콘덴서 유닛(3)과, 이 콘덴서 유닛(3)에서 응축작용을 하고 이 응축된 냉매를 증발시키는 증발기 유닛(4)이 모두 차량의 지붕(1)에 넓은 면적으로 설치되어 있었기 때문에 상기 유닛들과 압축기를 연결관으로 길게 연결시켜야 했으며, 이에 따라 상기 연결관들의 연결부위에서 차량의 진동이나 연결부위의 이완에 따라 냉매가 유출될 경우에는 이를 즉시 발견할 수 없게 되었고, 상기 냉매의 유출이 심하게 되어 에어컨의 기능이 발휘되지 않을 때 비로소 확인할 수 있게 되므로 상기 에어컨의 운용이 매우 어렵게 되는 폐단이 있었으며, 상기 버스차량의 경우에는 심할 경우 상기 에어컨을 가동시키지 못하게 됨에 따라 차량 실내를 쾌적하게 할 수 없는 점등의 문제점이 있었다.However, in the conventional art, the condenser unit 3 condensing the refrigerant compressed by the compressor and the evaporator unit 4 condensing in the condenser unit 3 and evaporating the condensed refrigerant are both vehicles. Since the unit was installed on a large area of the roof (1), the units and the compressor had to be connected to the connecting pipe for a long time. Accordingly, when the refrigerant flowed out due to the vibration of the vehicle or the loosening of the connecting part, It was not possible to find this immediately, and the leakage of the refrigerant was so severe that only when the function of the air conditioner is not exhibited, the operation of the air conditioner was very difficult, and in the case of the bus vehicle, if the severe As the air conditioner is not operated, there is a problem of lighting that cannot comfort the interior of the vehicle.

본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로, 본 발명은 버스차량 등의 지붕에 증발기 유닛과 콘덴서 유닛을 설치하고 이들을 차량의 후방 엔진룸에 설치되는 압축기와 연결관으로 각각 연결하도록 한 에어컨에 있어서, 상기 버스차량의 지붕에 설치되는 증발기 유닛과 콘덴서 유닛 및 압축기의 연결관 부위에 각각의 감지센서들을 설치하고 이들 감지센서의 신호에 따라 냉매의 유출을 확인할 수 있도록 한 차량의 지붕장착용 에어컨장치를 제공하려는 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional problems, the present invention is installed on the roof of the bus, such as evaporator unit and condenser unit and connected to each of the compressor and connecting pipes installed in the rear engine room of the vehicle In the air conditioner, the respective sensors are installed in the connection part of the evaporator unit, the condenser unit and the compressor installed on the roof of the bus vehicle, and the leakage of the refrigerant can be checked according to the signals of these sensors. It is to provide a roof mounted air conditioner, which will be described in detail based on the accompanying drawings as follows.
