자동차용 공기조화장치는 자동차의 실내를 냉방하기 위한 냉방시스템과 자동차의 실내를 난방하기 위한 난방시스템을 포함한다. 냉방시스템은 압축기의 구동에 의하여 토출되는 열교환 매체가 응축기, 리시버 드라이어, 팽창밸브 및 증발기를 거쳐 다시 압축기로 순환하는 과정에서 증발기와 실내, 외기와의 열교환에 의하여 자동차의 실내를 냉방하도록 구성되며, 한편 난방시스템은 냉각수를 히터 코어로유입시켜 실내외기와 열교환시킴으로써 자동차의 실내를 난방 하도록 구성된다.The automotive air conditioner includes a cooling system for cooling the interior of a vehicle and a heating system for heating the interior of the vehicle. The cooling system is configured to cool the interior of the vehicle by heat exchange between the evaporator, the interior and the outside in the process of circulating the heat exchange medium discharged by the operation of the compressor through the condenser, the receiver dryer, the expansion valve and the evaporator and back to the compressor. On the other hand, the heating system is configured to heat the interior of the vehicle by injecting cooling water into the heater core and exchanging heat with the outdoor air.

이러한 공기조화 장치의 일예가 일본 공개특허 평9-39553호에 개시되어 있다.An example of such an air conditioner is disclosed in Japanese Patent Laid-Open No. 9-39553.

개시된 공기조화 장치는 방열휜을 공유하는 제1열교환기와, 제2열교환기를 가지며, 상기 방열휜은 양 열교환기의 사이에 열을 차단하기 위해 절제부를 설치하고, 공기류의 토출측 부분이 상기 제1열교환기의 토출측 부분의 일부와 상기 제2열교환기의 토출측 부분의 전부에 의해 구성된 일체형 열교환기를 공기가 유통하는 통로 내에 설치하고, 상기 제1열교환기를 냉방 사이클의 증발기로 하고, 상기 제2열교환기를 엔진 내각수가 순환하는 온수 회로에 설치된 히터 코어로 한 구성이다.The disclosed air conditioner has a first heat exchanger and a second heat exchanger sharing a heat dissipation fin, and the heat dissipation fin is provided with an ablation section to block heat between both heat exchangers, and the discharge side portion of the air flow is the first heat exchanger. An integrated heat exchanger constituted by a part of the discharge side portion of the heat exchanger and all of the discharge side portion of the second heat exchanger is provided in a passage through which air flows, and the first heat exchanger is used as an evaporator in a cooling cycle, and the second heat exchanger It is the structure which consisted of the heater core installed in the hot water circuit in which engine internal water circulation.

상술한 바와 같이 구성된 본 발명에 따른 공기조화 장치의 작용을 설명하면 다음과 같다.Referring to the operation of the air conditioner according to the present invention configured as described above are as follows.

본 발명에 따른 공기조화 장치를 이용하여 자동차의 실내를 냉, 난방하기 위한 작용을 1 및 도 2, 4도를 참조하여 설명하면 다음과 같다.The operation for cooling and heating the interior of a vehicle using the air conditioner according to the present invention will be described with reference to FIGS. 1 and 2 and 4.

먼저 자동차의 실내를 난방하기 위하여 난방모드가 설정되면 제2열교환기(20)의 유입구(22)와 유출구(23)측에 설치된 워터 밸브(21)가 작동되어 열리게 됨으로써 엔진에 의해 가열된 냉각수는 제2열교환기(20)의 내부를 순환하게 된다. 이 상태에서 상기 제1탬프도어(51)는 제1분할통로(33)의 출구측에 설치된 제1탬프도어(51)가 제1분할통로(33)의 출구를 밀폐하게 되며, 제2템프도어(52)가 작동되어 제2분할통로의 출구가 열리게 된다. 이때에 상기 냉동시스템을 구성하는 압축기(11)는 작동되지 않게 되며, 운전자의 선택된 모드조작에 의해 디프로스트 도어(54), 밴트도어(55), 플로어 도어(56) 중의 적어도 하나가 열린 상태가 된다.First, when the heating mode is set to heat the interior of the vehicle, the water valve 21 installed at the inlet 22 and the outlet 23 of the second heat exchanger 20 is operated to open, so that the coolant heated by the engine is The inside of the second heat exchanger 20 is circulated. In this state, the first stamped door 51 has the first stamped door 51 installed at the outlet side of the first split passage 33 to seal the outlet of the first split passage 33 and the second tempored door. 52 is operated to open the outlet of the second dividing passage. At this time, the compressor 11 constituting the refrigeration system is not operated, and at least one of the defrost door 54, the vent door 55, and the floor door 56 is opened by the driver's selected mode operation. do.

이 상태에서 상기 송풍기(40)로부터 송풍된 공기는 제1열교환기(10)을 통과한 후 제2열교환기(20)를 통과하면서 가열된다. 가열된 공기는 열린 디프로스트 통로(35), 밴트통로(36) 및 플로어 통로(37)중 선택된 통로를 통하여 자동차의 실내로 공급됨으로써 난방을 행하게 된다. 상기와 같이 자동차의 실내가 난방되는 과정에서 선택된 모드, 예컨대 믹싱모드인 경우에는 제1탬프도어(51)가 열리게 되어 제2열교환기(20)를 통과하지 않은 공기와 통과한 공기가 혼합될 수 있다.In this state, the air blown from the blower 40 is heated while passing through the first heat exchanger 10 and then passing through the second heat exchanger 20. The heated air is supplied to the interior of the vehicle through a passage selected from the open defrost passage 35, the vent passage 36, and the floor passage 37 to perform heating. In the selected mode, for example, the mixing mode, in the process of heating the interior of the vehicle as described above, the first stamp door 51 may be opened to mix air that has not passed through the second heat exchanger 20 and air that has passed through. have.

그리고 상기 자동차 실내의 냉방하기 위한 냉방모드가 선택된 경우에는 상기워터밸브(21)가 작동되어 제2열교환기(20)로 유입되는 냉각수의 공급이 차단되고, 냉방시스템의 압축기(11)가 작동되어 제1열교환기(10) 내에서 열교환 매체가 증발되도록 함으로써 증발잠열에 의해 제1열교환기(10)가 냉각되도록 한다. 그리고 상기 제1분할통로(33)측에 설치된 제1템프도어(51)에 의해 제1분할통로(33)가 열리도록 하고, 제2탬프도어(52)가 제2열교환기(20)를 통과가 응축수 배출구(38)로 흐를 수 있도록 조작된다. 이와 같은 상태에서 초기 냉방시에 송풍기(40)로부터 공기의 일부는 제1열교환기(10)를 통과하면서 냉각된 후 자동차의 실내로 공급되고, 일부의 공기는 제1열교환기(10)를 통과한 후 제2열교환기(20)를 통과하면서 제2열교환기(20) 내의 냉가수를 냉각시키게 된다.When the cooling mode for cooling the vehicle interior is selected, the water valve 21 is operated to block the supply of the coolant flowing into the second heat exchanger 20, and the compressor 11 of the cooling system is operated. By allowing the heat exchange medium to evaporate in the first heat exchanger 10, the first heat exchanger 10 is cooled by latent heat of evaporation. Then, the first split passage 33 is opened by the first temporal door 51 installed on the first split passage 33 side, and the second tamper door 52 passes through the second heat exchanger 20. Is operated to flow to the condensate outlet 38. In this state, during the initial cooling, a part of the air from the blower 40 is cooled while passing through the first heat exchanger 10 and then supplied to the interior of the vehicle, and a part of the air passes through the first heat exchanger 10. After cooling the cold water in the second heat exchanger 20 while passing through the second heat exchanger 20.

상기 제2열교환기(20)의 냉각수가 충분히 냉각된 상태가 센서에 의해 감지되면 제2탬프도어(52)가 작동되어 도 1의 가상선으로 나타내 보인 바와 같이 응축수 배출구로의 공기 흐름을 차단하고 제2열교환기를 통과한 공기가 제1열교환기를 통과한 공기와 합쳐지도록 한다.When the state in which the coolant of the second heat exchanger 20 is sufficiently cooled is sensed by the sensor, the second stamp door 52 is operated to block the air flow to the condensate outlet as shown by the virtual line of FIG. The air passing through the second heat exchanger is combined with the air passing through the first heat exchanger.

상기와 같은 조작으로 초기 냉방시 히터 코어인 제2열교환기(20)를 통과하??서 가열된 냉각수에 의해 냉방효율이 저하되는 것을 근본적으로 해결할 수 있다.By the above operation, it is possible to fundamentally solve that the cooling efficiency is lowered by the cooling water heated by passing through the second heat exchanger 20 that is the heater core during initial cooling.

본 발명의 공기조화 장치의 작용은 냉방과 난방를 일예로 들어 설명하였으나 상기 각 템프도어와 분배통로에 설치되는 도어들의 조작을 통하여 다양한 냉, 난방모드의 구현이 가능하다.The operation of the air conditioner of the present invention has been described with reference to the cooling and heating as an example, it is possible to implement a variety of cooling, heating mode through the operation of the doors installed in each of the tempdoor and the distribution passage.
