종래의 하이브리드 차량의 경우에는 차량이 정차하여 내연기관이 정지한 경우에, 에어컨 압축기의 구동을 위해 배터리로부터 제공되는 전기를 사용한다.In the conventional hybrid vehicle, when the vehicle stops and the internal combustion engine is stopped, electricity provided from the battery is used to drive the air conditioner compressor.

상기와 같이 압축기를 구동하기 위해 소모되는 전기에너지는 매우 크므로 배터리에 상당한 부하로 작용하게 되며, 차량이 정차후 다시 출발할 때 압축기까지 함께 구동해야 하므로 전기모터에 매우 큰 부하가 작용하게 된다.As described above, the electrical energy consumed to drive the compressor is very large, which acts as a significant load on the battery, and when the vehicle starts again after stopping, it must be driven together to the compressor, which causes a very large load on the electric motor.

본 발명은 하이브리드 차량이 정차하여 내연기관이 정지한 경우에 에어컨시스템의 압축기를 구동하지 않고도 실내의 냉방이 이루어질 수 있도록 함으로써, 배터리의 전기부하를 줄이고, 정차후 출발시에 전기모터에 압축기를 구동하기 위한 부하를 추가로 주지 않을 수 있도록 한 하이브리드 차량의 에어컨시스템을 제공함에 그 목적이 있다.According to the present invention, when the hybrid vehicle stops and the internal combustion engine stops, cooling the room can be performed without driving the compressor of the air conditioning system, thereby reducing the electric load of the battery and driving the compressor to the electric motor at the start after stopping. It is an object of the present invention to provide an air conditioning system of a hybrid vehicle so that no additional load is required.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1을 참조하면, 본 발명 실시예는 증발기(1)에 의해 냉각된 공기와 열교환이 이루어지도록 설치된 증발기측열교환기(3)와, 연료탱크(5)내의 연료와 열교환이 이루어지도록 설치된 탱크측열교환기(7)와, 상기 증발기측열교환기(3)와 탱크측열교환기(7) 사이에 열을 전달할 수 있는 유체가 순환할 수 있도록 구비된 순환배관(9)과, 상기 순환배관(9)을 통해 유체가 순환하도록 설치된 순환모터(11)와, 상기 순환모터(11)를 제어하는 컨트롤러(13)를 포함하여 구성된다.Referring to Figure 1, the embodiment of the present invention is the tank side installed so that heat exchange with the fuel in the fuel tank (5) and the evaporator side heat exchanger (3) installed so as to exchange heat with the air cooled by the evaporator (1) A heat exchanger (7), a circulation pipe (9) provided for circulating fluid capable of transferring heat between the evaporator side heat exchanger (3) and the tank side heat exchanger (7), and the circulation pipe (9) It is configured to include a circulation motor 11 and the controller 13 for controlling the circulation motor 11 installed to circulate the fluid through the).

내연기관(15)에서 발생되는 동력은 전기모터(17)에서 발생되는 동력과 함께 적절히 구동륜(19)으로 전달되게 되어 있다. 상기 내연기관(15)의 크랭크샤프트로부터 인출되는 동력으로 압축기(21)가 구동될 수 있도록 되어 있으며, 상기 압축기(21)에서 압축된 냉매는 응축기(23)를 거쳐 상기 증발기(1)에서 팽창하면서 냉각되고, 다시 상기 압축기(21)로 순환하도록 되어 있다.The power generated by the internal combustion engine 15 is properly transmitted to the drive wheels 19 together with the power generated by the electric motor 17. The compressor 21 is driven by the power drawn from the crankshaft of the internal combustion engine 15, and the refrigerant compressed by the compressor 21 expands in the evaporator 1 via the condenser 23. It cools and circulates to the said compressor 21 again.

상기 탱크측열교환기(7)는 연료탱크(5) 내에서 연료와 열교환이 이루어질 수 있도록 연료에 잠겨 있다.The tank side heat exchanger 7 is immersed in fuel so that heat exchange with the fuel can occur in the fuel tank 5.

도 2를 참조하면, 에어컨스위치(27)가 온(on)되면 상기 증발기팬(25)이 구동하도록 되어 있고, 상기 컨트롤러(13)는 상기 에어컨스위치(27)가 온 상태인 경우, 상기 순환모터(11)와 압축기(21)의 작동을 제어할 수 있도록 되어 있다.Referring to FIG. 2, when the air conditioner switch 27 is turned on, the evaporator fan 25 is driven. When the air conditioner switch 27 is turned on, the circulator motor The operation of the 11 and the compressor 21 can be controlled.

상기 컨트롤러(13)는 내연기관(15)이 작동중인 차량의 주행시에는 도 2에 도시된 바와 같이 상기 순환모터(11)와 압축기(21)를 작동시킨다. 여기서 상기 컨트롤러(13)가 압축기(21)를 작동시킨다는 것은 상기 컨트롤러(13)가 압축기(21)의 마그네틱클러치를 작동시켜서 크랭크샤프트로부터의 회전력으로 압축기(21)가 실질적으로 구동되도록 함을 의미한다.The controller 13 operates the circulation motor 11 and the compressor 21 as shown in FIG. 2 when the internal combustion engine 15 is driven. Here, the operation of the compressor 21 by the controller 13 means that the controller 13 operates the magnetic clutch of the compressor 21 so that the compressor 21 is substantially driven by the rotational force from the crankshaft. .

상기 증발기(1)를 통과하는 차가운 공기는 상기 증발기측열교환기(3)를 냉각시킨다. 상기 순환모터(11)는 상기 증발기측열교환기(3)에서 냉각된 유체가 상기 탱크측열교환기(7)로 공급되도록 한다.Cold air passing through the evaporator 1 cools the evaporator side heat exchanger 3. The circulation motor 11 allows the fluid cooled in the evaporator side heat exchanger 3 to be supplied to the tank side heat exchanger 7.

상기 탱크측열교환기(7)에서는 상기 냉각된 유체가 통과하면서 연료를 냉각시키고, 다시 상기 증발기측열교환기(3)로 순환한다.The tank side heat exchanger 7 cools the fuel while the cooled fluid passes, and circulates to the evaporator side heat exchanger 3 again.

따라서, 상기 내연기관(15)이 작동중인 경우에 에어컨시스템은 상기 증발기(1)에서 냉각된 공기로 실내를 냉각시킴과 동시에, 상기 연료탱크(5)내의 연료를 냉각시켜 두게 되는 것이다.Therefore, when the internal combustion engine 15 is in operation, the air conditioner system cools the room with the air cooled in the evaporator 1 and simultaneously cools the fuel in the fuel tank 5.

상기 에어컨스위치(27)가 온(on)인 상태에서, 상기 내연기관(15)이 정지상태인 차량의 정차시에는 상기 컨트롤러(13)는 도 3에 도시된 바와 같이 상기 압축기(21)는 작동시키지 않고 순환모터(11)만 작동시킨다. In the state where the air conditioner switch 27 is turned on, when the vehicle in which the internal combustion engine 15 is stopped stops, the controller 13 operates the compressor 21 as shown in FIG. 3. Only the circulating motor 11 is operated.

따라서, 상기 증발기(1)는 냉각기능을 발휘하지 못하지만, 상기 탱크측열교환기(7)에서 제공되는 차가운 유체는 상기 증발기측열교환기(3)에서 냉각기능을 발휘하게 된다.Thus, the evaporator 1 does not perform a cooling function, but the cold fluid provided in the tank side heat exchanger 7 performs a cooling function in the evaporator side heat exchanger 3.

물론, 상기 증발기측열교환기(3)에서 열교환을 마친 유체는 다시 탱크측열교환기(7)로 순환되면서 연료로부터의 냉기를 증발기측열교환기(3)로 이송하게 된다.Of course, the fluid after the heat exchange in the evaporator side heat exchanger (3) is circulated back to the tank side heat exchanger (7) to transfer the cool air from the fuel to the evaporator side heat exchanger (3).

따라서, 상기 내연기관(15)이 정지된 상태에서 별도의 모터로 압축기(21)를 작동시키지 않고도 증발기측열교환기(3)로 공기를 통과시켜서, 냉각된 공기를 실내에 송풍함으로써, 실내의 냉각작용이 지속적으로 이루어질 수 있도록 한다.Therefore, the air is cooled by passing air through the evaporator side heat exchanger 3 without blowing the compressor 21 by a separate motor in the state where the internal combustion engine 15 is stopped and blowing the cooled air into the room, thereby cooling the room. Ensure that the action is continuous.

즉, 상기 내연기관(15)이 구동되면서 에어컨시스템이 작동되는 동안에 연료탱크(5)의 연료를 냉각시켜 두었다가, 상기 내연기관(15)에 의해 압축기(21)를 구동하기 어려운 상황에서, 냉각되어 있는 연료를 이용하여 실내로 공급할 공기를 냉각시킬 수 있도록 하는 것이다.That is, while the internal combustion engine 15 is driven, the fuel of the fuel tank 5 is cooled while the air conditioner system is operating, and is cooled in a situation where it is difficult to drive the compressor 21 by the internal combustion engine 15. It is to use the fuel to cool the air to be supplied to the room.

이상과 같이 본 발명에 의하면, 하이브리드 차량이 정차하여 내연기관이 정지한 경우에 에어컨시스템의 압축기를 구동하지 않고도 실내의 냉방이 이루어질 수 있도록 함으로써, 배터리의 전기부하를 줄이고, 차량의 정차후 출발시에 전기모터에 압축기를 구동하기 위한 부하를 추가로 주지 않을 수 있도록 한다.As described above, according to the present invention, when the hybrid vehicle is stopped and the internal combustion engine is stopped, cooling of the room can be performed without driving the compressor of the air conditioning system, thereby reducing the electric load of the battery and starting the vehicle after stopping. Do not apply additional load to the electric motor to drive the compressor.
