본 발명은 차량용 공조장치에 관한 것으로써, 더욱 상세하게는 난방장치의 제1냉각수순환라인과 전장품 냉각장치의 제2냉각수순환라인을 연결하는 연결라인 및 냉각수 유동방향을 전환하는 방향전환밸브를 설치하여 엔진주행모드 또는 전기주행모드에 따라 상기 난방장치 또는 전장품 냉각장치의 열원을 선택적으로 차실내 난방에 사용하도록 함으로써, 엔진주행모드에서는 엔진의 열원을 사용함은 물론 전장품 냉각장치를 예열하고, 전기주행모드에서는 초기구간은 엔진 잔열을 사용하고 이후 전장품의 폐열을 사용하도록 한 차량용 공조장치에 관한 것이다.The present invention relates to a vehicle air conditioning system, and more particularly, to a vehicular air conditioning system including a connection line connecting a first cooling water circulation line of a heating device and a second cooling water circulation line of an electrical component cooling device, and a direction switching valve The heat source of the heating device or the electric component cooling device is selectively used for heating the vehicle in accordance with the engine running mode or the electric running mode. In the engine running mode, not only the engine heat source but also the electric component cooling device are preheated, Mode, the initial section uses the engine residual heat and then uses the waste heat of the electrical component.

차량용 공조장치는, 통상적으로 차량의 실내를 냉방하기 위한 냉방시스템과, 차량의 실내를 난방하기 위한 난방시스템을 포함하여 이루어진다. 상기 냉방시스템은, 냉매사이클의 증발기측에서 증발기의 외부를 거치는 공기를 증발기 내부를 흐르는 냉매와 열교환시켜 냉기로 바꾸어, 차량 실내를 냉방하도록 구성되고, 상기 난방시스템은 냉각수 사이클의 히터코어측에서 히터코어 외부를 거치는 공기를 히터코어 내부를 흐르는 냉각수와 열교환시켜 온기로 바꾸어, 차량 실내를 난방하도록 구성된다.Background Art [0002] A vehicle air conditioner generally includes a cooling system for cooling the interior of a vehicle and a heating system for heating the interior of the vehicle. Wherein the cooling system is configured to cool air in the vehicle interior by exchanging air passing through the outside of the evaporator at the evaporator side of the refrigerant cycle with the refrigerant flowing in the evaporator to convert into cool air, The air passing through the outside of the core is exchanged with the cooling water flowing in the inside of the heater core to warm the inside of the vehicle.

최근 하이브리드 차량은, 엔진과 모터를 동시에 탑재하여 이를 동시에 구동하거나, 선택적으로 구동하여 구동력을 얻는 차량이다. 여기서, 구동모터를 포함한 전장품은 작동시 열이 발생되고 부품들의 입출력 특성을 최상의 상태로 유지하기 위하여 부품의 온도 상승을 억제하는 냉각장치를 설치할 필요가 있다. 특히, 배터리의 경우에는 전체적인 충방전 효율을 최상으로 유지하기 위해서는 적정온도를 유지하여야 한다.Recently, a hybrid vehicle is a vehicle that simultaneously mounts an engine and a motor and simultaneously drives them or selectively drives them to obtain a driving force. Here, it is necessary to provide a cooling device for suppressing an increase in the temperature of components, in order to generate heat during operation and maintain the input / output characteristics of the components in the best condition. Particularly, in the case of a battery, an appropriate temperature should be maintained in order to maintain the overall charge-discharge efficiency at the highest level.

또한, 엔진을 냉각하는 냉각장치도 설치되며, 이때 상기 엔진을 순환하는 냉각수를 상기 히터코어로 순환시켜 차실내 난방을 수행하게 된다.In addition, a cooling device for cooling the engine is also installed, and the cooling water circulating in the engine is circulated to the heater core to perform heating in the car.

도 1은, 종래의 하이브리드 차량용 공조장치를 나타낸 구성도로서, 제1냉각수순환라인(1)상에 엔진(10), 워터펌프(11), 공조케이스내의 히터코어(12), 라디에이터(13)를 연결하여 구성되며, 상기 라디에이터(13)를 통해 엔진(10)을 냉각함과 아울러 상기 엔진(10)에 의해 가열된 냉각수를 상기 공조케이스내의 히터코어(12)로 순환시켜 공조케이스내를 유동하는 공기를 가열함으로써 차실내를 난방하게 된다.Fig. 1 shows a conventional air conditioning system for a hybrid vehicle. The engine 10, the water pump 11, the heater core 12 in the air conditioning case, the radiator 13, Cooling the engine 10 through the radiator 13 and circulating the cooling water heated by the engine 10 to the heater core 12 in the air conditioning case so as to flow in the air conditioning case So that the interior of the vehicle is heated.

한편, 상기 제1냉각수순환라인(1)과는 별도로 차량 전장품(21)을 냉각하기 위한 제2냉각수순환라인(2)이 설치되며, 상기 제2냉각수순환라인(2)상에는 차량 전장품(21), 전장 라디에이터(22), 모터(23)를 연결하여 상기 전장품(21) 및 모터(23)를 냉각함과 아울러 적정온도로 유지시키게 된다.A second cooling water circulation line 2 for cooling the vehicle electrical component 21 is provided separately from the first cooling water circulation line 1 and a vehicle electrical component 21 is installed on the second cooling water circulation line 2, The electric vehicle 21 and the motor 23 are connected to each other by the electric motor 22 and the electric motor 23 so that the electrical equipment 21 and the motor 23 are cooled.

따라서, 엔진주행모드시에는, 상기 엔진(10)이 온(ON) 되므로 엔진(10)의 열원을 이용하여 차실내 난방을 수행하게 되고, 전기주행모드로 전환시에는 상기 엔진(10)이 오프(OFF) 되기 때문에 엔진(10) 온(ON) 상태였을때 가열되었던 열원만을 사용하다가 난방관리온도(냉각수 온도)가 일정온도 이하로 떨어지면 상기 엔진(10)을 재시동하여 난방을 수행하였다.Accordingly, in the engine running mode, the engine 10 is turned on, so that the vehicle 10 is heated using the heat source of the engine 10. When the engine 10 is switched to the electric running mode, When the heating management temperature (cooling water temperature) falls below a predetermined temperature while using only the heat source which has been heated when the engine 10 is turned on, the engine 10 is restarted to perform heating.

그러나, 상기 종래 기술은, 엔진(10)의 열원만을 차실내 난방에 활용하기 때문에 엔진(10)이 오프(OFF) 되는 전기주행모드시 난방관리온도(냉각수 온도)가 일정온도 이하로 떨어지면 상기 엔진(10)을 재시동하게 되고, 이러한 엔진(10) 재시동이 빈번하게 발생하여 연비가 감소하는 문제가 있다.However, when the heating management temperature (cooling water temperature) in the electric running mode in which the engine 10 is turned off falls below a certain temperature because only the heat source of the engine 10 is utilized for heating the interior of the vehicle, The engine 10 is restarted, and the restart of the engine 10 is frequently caused, thereby reducing fuel consumption.

또한, 전기주행모드의 초기구간 및 엔진(10) 재시동 초기구간에서 난방능력이 저하되는 문제도 있었다.In addition, there is a problem that the heating capacity is lowered in the initial section of the electric running mode and the initial section of the engine 10.

상기한 문제점을 해결하기 위한 본 발명의 목적은 난방장치의 제1냉각수순환라인과 전장품 냉각장치의 제2냉각수순환라인을 연결하는 연결라인 및 냉각수 유동방향을 전환하는 방향전환밸브를 설치하여 엔진주행모드 또는 전기주행모드에 따라 상기 난방장치 또는 전장품 냉각장치의 열원을 선택적으로 차실내 난방에 사용하도록 함으로써, 엔진주행모드에서는 엔진의 열원을 사용함은 물론 전장품 냉각장치를 예열하고, 전기주행모드에서는 초기구간은 엔진 잔열을 사용하고 이후 전장품의 폐열을 사용하므로, 엔진의 재시동 시점을 지연시켜 연비를 향상할 수 있고, 엔진 잔열과 전장품의 폐열 및 PTC히터를 효율적으로 활용하여 난방성능을 향상함은 물론 PTC히터의 가동율을 줄여 소비전력도 절감 할 수 있으며, 전기주행모드의 초기구간 및 엔진 재시동 초기구간에서 난방능력 저하를 방지할 수 있는 차량용 공조장치을 제공하는데 있다.In order to solve the above problems, an object of the present invention is to provide a refrigeration system in which a connection line connecting a first cooling water circulation line of a heating device and a second cooling water circulation line of an electrical component cooling device, and a direction switching valve for switching a cooling water flow direction, Mode or the electric running mode, the heat source of the heating device or the electric component cooling device is selectively used for heating the interior of the vehicle. In the engine running mode, not only the engine heat source but also the electric component cooling device are preheated, Since the engine residual heat is used and the waste heat of the electrical equipment is used thereafter, the fuel consumption can be improved by delaying the restart time of the engine, and the heating performance can be improved by efficiently utilizing the engine residual heat and waste heat of the electric component and the PTC heater It is possible to reduce the operating rate of the PTC heater to reduce the power consumption, and the initial section of the electric driving mode and the engine In the initial start-up period it is to provide a vehicle air conditioning jangchieul to avoid the heating capacity decreases.

상기한 목적을 달성하기 위한 본 발명은, 제1냉각수순환라인상에 엔진과 워터펌프 및 공조케이스내의 히터코어를 연결하여 차실내 난방을 수행하는 난방장치와, 제2냉각수순환라인상에 차량 전장품과 전장 라디에이터와 워터펌프를 연결하여 차량 전장품을 냉각하는 전장품 냉각장치를 포함하여 이루어진 차량용 공조장치에 있어서, 상기 난방장치와 상기 전장품 냉각장치 상호간에 냉각수 유동이 가능하도록 상기 제1냉각수순환라인과 제2냉각수순환라인을 연결하는 연결라인이 설치되고, 상기 제1냉각수순환라인 및 제2냉각수순환라인과 상기 연결라인이 만나는 특정 지점에는 냉각수의 유동방향을 전환하는 방향전환밸브가 설치되며, 엔진주행모드 또는 전기주행모드에 따라 상기 난방장치 또는 전장품 냉각장치의 열원을 선택적으로 차실내 난방에 사용하도록 상기 방향전환밸브를 제어하는 제어부가 구비된 것을 특징으로 한다.According to another aspect of the present invention, there is provided a cooling system for a vehicle, comprising: a heating device for heating a vehicle interior by connecting an engine, a water pump, and a heater core in an air conditioning case to a first cooling water circulation line; And an electric component cooling device for cooling the vehicle electrical component by connecting the electric-field radiator and the water pump, wherein the first cooling water circulation line and the second cooling water circulation line are connected to each other so that the cooling water can flow between the heating device and the electric component cooling device.

본 발명에 따른 차량용 공조장치는, 하이브리드 자동차에 적용되는 것으로서, 크게 난방장치(100a)와, 전장품 냉각장치(100b)와, 연결라인(103,104)과, 방향전환밸브(131,132,133)와, 제어부(미도시)로 구성된다.The vehicle air conditioner according to the present invention is applied to a hybrid vehicle and mainly includes a heating device 100a, an electric component cooling device 100b, connection lines 103 and 104, direction switching valves 131, 132 and 133, Time).

상기 난방장치(100a)는, 제1냉각수순환라인(101)상에 엔진(110)과 워터펌프(111) 및 공조케이스(140)내의 히터코어(112)를 연결하여 구성된다.The heating device 100a is constructed by connecting the engine 110 with the water pump 111 and the heater core 112 in the air conditioning case 140 on the first cooling water circulation line 101. [

이때, 상기 워터펌프(111)는 냉각수의 유량 제어가 가능한 전동워터펌프를 사용하는 것이 바람직하다.At this time, the water pump 111 preferably uses an electric water pump capable of controlling the flow rate of the cooling water.

따라서, 상기 워터펌프(111)가 작동하면 상기 제1냉각수순환라인(101)을 순환하는 냉각수가 상기 엔진(110)에서 가열된 후 상기 히터코어(112)로 공급되며, 이때 상기 공조케이스(140)내를 유동하는 공기가 상기 히터코어(112)를 통과하면서 가열되어 차실내로 토출됨으로써 차실내 난방이 수행되는 것이다.Therefore, when the water pump 111 operates, cooling water circulating through the first cooling water circulation line 101 is heated by the engine 110 and then supplied to the heater core 112.
