차량용 배터리 온도조절장치 및 이를 구비한 차량용 공조장치{BATTERY TEMPERATURE CONTROL DEVICE FOR VEHICLE AND AIR CONDITIONER FOR VEHICLE THEREWITH}Vehicle battery temperature controller and vehicle air conditioner having the same

본 발명은 차량용 배터리 온도조절장치 및 이를 구비한 차량용 공조장치에 관한 것으로, 보다 상세하게는 차량 내부를 난방하며 배터리를 히팅하는 차량용 배터리 온도조절장치 및 이를 구비한 차량용 공조장치에 관한 것이다.The present invention relates to a vehicle battery temperature controller and an air conditioner for a vehicle having the same, and more particularly, to a vehicle battery temperature controller for heating a battery by heating the inside of a vehicle and a vehicle air conditioner having the same.

최근 자동차는 연소식 엔진을 사용하는 자동차에서 환경친화적이고, 연비를 고려한 또 다른 형태의 자동차, 즉, 하이브리드 자동차나 전기자동차로의 개발이 전 세계적으로 활발히 개발되고 있다.In recent years, development of automobiles from vehicles using combustion engines to other types of vehicles that are environmentally friendly and consider fuel efficiency, that is, hybrid vehicles or electric vehicles, is being actively developed around the world.

하이브리드 자동차는 기존의 엔진과 전기에너지로 구동되는 모터를 연계하여 두 가지의 동력원으로 구동되고, 전기자동차는 전기에너지로 구동되는 모터만으로 구동된다. 이러한 하이브리드 자동차와 전기자동차는 배기가스에 의한 환경오염의 저감과 함께 연비향상의 효과로 인하여 미국과 일본을 중심으로 최근 각광을 받고 있는 대안적인 차세대 자동차로 자리매김하고 있다.A hybrid vehicle is driven by two power sources by linking a conventional engine and a motor driven by electric energy, while an electric vehicle is driven only by a motor driven by electric energy. These hybrid vehicles and electric vehicles are positioning themselves as alternative next-generation vehicles that have recently been in the limelight, mainly in the United States and Japan, due to the effect of reducing environmental pollution caused by exhaust gas and improving fuel efficiency.

이러한 하이브리드 자동차나 전기자동차에는 고용량 배터리가 장착되고, 이러한 배터리는 필요시에는 모터로 전력을 공급하고 차량의 감속, 정지시에는 재생동력원으로부터 생성되는 전기에너지를 충전하는 역할을 하고 있다.A high-capacity battery is installed in such a hybrid vehicle or an electric vehicle, and the battery serves to supply power to a motor when necessary and to charge electric energy generated from a renewable power source when the vehicle decelerates or stops.

이와 같은 고용량 배터리는 온도의 영향을 많이 받는다. 즉, 상기 배터리의 온도가 일정범위 내에서는 높으면 높을수록 충전 및 방전량이 증가하여 배터리의 효율이 높아진다. 반면, 겨울철과 같이 실외 온도가 낮은 경우에는 배터리의 온도가 낮아져 충전 및 방전 효율이 떨어짐은 물론 배터리의 용량과 출력이 감소되며 심할 경우 시동이 곤란하게 되는 문제가 발생할 수 있다.Such a high-capacity battery is greatly affected by temperature. That is, as the temperature of the battery is higher within a certain range, the amount of charging and discharging increases, thereby increasing the efficiency of the battery. On the other hand, when the outdoor temperature is low, such as in winter, the temperature of the battery is lowered, and charging and discharging efficiency is lowered, as well as the capacity and output of the battery are reduced, and in severe cases, a problem of starting is difficult.

상기한 문제를 해결하기 위해 배터리 온도조절장치를 통해 배터리의 온도를 일정온도 이상으로 유지하도록 하고 있다.In order to solve the above problem, the temperature of the battery is maintained at a certain temperature or higher through a battery temperature controller.

도 1은 공개특허 2015-0026176(특허문헌 1)에 개시된 종래의 차량용 배터리 온도조절장치이다. 도시된 바와 같이, 종래의 차량용 배터리 온도조절장치는. 냉방장치(1)와, 배터리냉각장치(2)와, 배터리 히팅수단(3)을 포함하여 구성된다.1 is a conventional vehicle battery temperature controller disclosed in Patent Publication 2015-0026176 (Patent Document 1). As shown, the conventional vehicle battery temperature control device. It is configured to include a cooling device (1), a battery cooling device (2), and a battery heating means (3).

냉방장치(1)는 차량 실내를 냉방하는 장치로서, 냉매순환라인 상에 설치된 압축기(4), 응축기(5), 팽창수단(6), 증발기(7)로 이루어진다. 배터리 히팅수단(3)은, 압축기(4)와 응축기(5) 사이의 냉매순환라인 상에 병렬로 연결되는 분기냉매라인과 냉각수를 열교환하도록 구성된다.The cooling device 1 is a device for cooling the interior of a vehicle, and is composed of a compressor 4 installed on a refrigerant circulation line, a condenser 5, an expansion unit 6, and an evaporator 7. The battery heating means 3 is configured to heat-exchange the cooling water with the branch refrigerant line connected in parallel on the refrigerant circulation line between the compressor 4 and the condenser 5.

즉, 배터리 히팅수단(3)은 기존 냉방장치(1)의 냉매를 열원으로 하여 배터리냉각장치(2)를 순환하는 냉각수를 히팅하고, 히팅된 냉각수는 냉각수순환라인에 연결된 배터리(8)를 히팅할 수 있다.That is, the battery heating means 3 uses the refrigerant of the existing cooling device 1 as a heat source to heat the cooling water circulating in the battery cooling device 2, and the heated cooling water heats the battery 8 connected to the cooling water circulation line. can do.

종래의 차량용 배터리 온도조절장치는 냉방장치의 냉매를 열원으로 하기 때문에 냉방장치를 사용하는 경우에만 작동이 가능하다는 문제가 있었다. 특히, 배터리의 히팅이 필요한 경우는 차량의 냉방을 필요로 하지 않는 겨울철인 경우가 대부분이기 때문에 비효율적이라는 문제점이 있었다.Conventional battery temperature controllers for vehicles use the refrigerant of the air conditioner as a heat source, so there is a problem in that they can be operated only when the air conditioner is used. In particular, when heating of the battery is required, there is a problem in that it is inefficient because most of the cases are in winter when cooling of the vehicle is not required.

For example, when the temperature inside the vehicle is low enough to require vehicle heating but the battery 210 is sufficiently heated, the cooling water flows only to the heater core 240 by the cooling water valve 310 and bypasses the battery 210. can

또한, 차량의 난방은 필요하지 않으나 배터리(210)의 히팅이 필요한 경우에는 배터리(210)로만 냉각수를 유동시킨다. 도 3 내지 도 6의 난방모드에서는 차량의 난방 및 배터리(210)의 히팅이 모두 수행되는 경우를 도시하였다.In addition, when heating of the vehicle is not required, but heating of the battery 210 is required, coolant flows only through the battery 210 .

At this time, since the cooling water heat exchanger 220 and the outdoor heat exchanger 120 serve as a condenser and the indoor heat exchanger 130 serves as an evaporator, the indoor heat exchanger 130 exchanges heat with the air inside the air conditioning case 160 to drive the vehicle. Cool air can be supplied to the inside.

이때, 냉매는 압축기(110)를 통과한 후 냉매순환라인(R) 상에 설치된 제 1 밸브(155)에 의해 제 1 바이패스라인(R1)을 따라 유동하며 제 2 팽창수단(150)을 바이패스한다. 제 1 밸브(155)는 2웨이 밸브의 형태로 마련되어 냉매가 제 2 팽창수단(150)을 통과하거나 바이패스하도록 구성될 수 있다.At this time, the refrigerant passes through the compressor 110, flows along the first bypass line R1 by the first valve 155 installed on the refrigerant circulation line R, and bypasses the second expansion means 150. pass The first valve 155 may be provided in the form of a two-way valve so that the refrigerant passes through or bypasses the second expansion means 150 .

결과적으로 차량 내부는 냉방되고, 냉각수 순환라인(W)은 작동하지 않아 배터리 히팅은 수행되지 않는다.As a result, the inside of the vehicle is cooled, and the battery heating is not performed because the coolant circulation line (W) does not operate.

도 3은 본 발명의 실시 예에 따른 차량용 배터리 온도조절장치(200)를 구비한 차량용 공조장치(100)의 제 1 난방모드를 도시한 구성도이다. 제 1 난방모드는 최대 난방 성능이 요구될 때 효율적인 난방모드이다.3 is a configuration diagram showing a first heating mode of the vehicle air conditioner 100 having the vehicle battery temperature controller 200 according to an embodiment of the present invention. The first heating mode is an efficient heating mode when maximum heating performance is required.

냉매는 압축기(110), 냉각수 열교환기(220), 제 2 팽창수단(150), 실외 열교환기(120), 칠러(190), 어큐뮬레이터(170)를 통과하여 다시 압축기(110)로 순환한다. 이때, 냉각수 열교환기(220)는 응축기, 실외 열교환기(130)는 증발기의 역할을 한다.The refrigerant passes through the compressor 110, the cooling water heat exchanger 220, the second expansion unit 150, the outdoor heat exchanger 120, the chiller 190, and the accumulator 170, and circulates back to the compressor 110. At this time, the cooling water heat exchanger 220 serves as a condenser and the outdoor heat exchanger 130 serves as an evaporator.

냉매는 실외 열교환기(130)를 통과한 후 냉매순환라인(R) 상에 설치된 제 2 밸브(165)에 의해 제 2바이패스라인(R2)을 따라 유동하며 실내 열교환기(130)와 제 1 팽창수단(140)을 바이패스한다. 제 2 밸브(165)는 3웨이 밸브의 형태로 마련되어 실외 열교환기(120)를 통과한 냉매를 냉매순환라인(R) 또는 제 2 바이패스라인(R2)으로 개방할 수 있다.After passing through the outdoor heat exchanger 130, the refrigerant flows along the second bypass line R2 by the second valve 165 installed on the refrigerant circulation line R, and the indoor heat exchanger 130 and the first The expansion means 140 is bypassed. The second valve 165 is provided in the form of a 3-way valve and can open the refrigerant passing through the outdoor heat exchanger 120 to the refrigerant circulation line R or the second bypass line R2.

이때, 제 1 밸브(155)는 냉매가 냉매순환라인(R)으로 유동할 수 있도록 냉매유로를 개방한다. 그에 따라, 압축기(110)를 통과한 냉매는 냉각수 열교환기(330)로 유동되고, 냉각수 열교환기(220)를 통과한 냉매는 제 2 팽창수단(150)을 통과하도록 유동된다.At this time, the first valve 155 opens the refrigerant passage so that the refrigerant can flow into the refrigerant circulation line (R). Accordingly, the refrigerant passing through the compressor 110 flows into the cooling water heat exchanger 330, and the refrigerant passing through the cooling water heat exchanger 220 flows through the second expansion unit 150.

또한, 냉각수 펌프(250)에 의해 냉각수순환라인(W)도 작동하여 배터리(210)를 히팅시키며 히터 코어(240)에 의해 차량 내부에 난방열을 공급한다. 즉, 냉각수밸브(310)는 배터리(210) 및 히터 코어(240)로 냉각수를 유동시킨다. 앞서 설명한 바와 같이, 필요에 따라 냉각수밸브(310)는 배터리(210) 또는 히터 코어(240)로 냉각수를 유동시킬 수 있다.In addition, the coolant circulation line W is also operated by the coolant pump 250 to heat the battery 210 and the heater core 240 supplies heating heat to the inside of the vehicle. That is, the cooling water valve 310 causes the cooling water to flow to the battery 210 and the heater core 240 . As described above, the cooling water valve 310 may flow cooling water to the battery 210 or the heater core 240 as needed.

또한, 차량 전장품(180)을 순환하는 냉각수도 순환하며 칠러(190)에서 전장폐열과 냉매가 열교환된다.In addition, the coolant circulating through the vehicle electrical components 180 also circulates, and heat is exchanged between electrical waste heat and the refrigerant in the chiller 190 .

결과적으로 차량 내부가 난방 됨과 동시에 배터리(210) 히팅이 수행된다. 이때, 배터리(210)가 일정온도 이상인 경우, 냉각수 밸브(310)가 배터리(210)로 유동되는 냉각수의 유동을 차단할 수 있다. 그에 따라, 배터리(210)가 일정온도 이하로 되는 경우, 냉각수 밸브(310)가 다시 배터리(210)로 냉각수를 유동시킬 수 있다.As a result, the battery 210 is heated at the same time as the inside of the vehicle is heated. In this case, when the temperature of the battery 210 is higher than a certain temperature, the cooling water valve 310 may block the flow of cooling water flowing into the battery 210 . Accordingly, when the temperature of the battery 210 is below a certain temperature, the cooling water valve 310 may flow the cooling water back to the battery 210 .

도 4는 본 발명의 실시 예에 따른 차량용 배터리 온도조절장치(200)를 구비한 차량용 공조장치(100)의 제 1 난방제습모드를 도시한 구성도이다. 제 1 난방제습모드는 제 1 난방모드에서 제습이 필요한 경우 수행되는 난방모드이다.4 is a configuration diagram showing a first heating and dehumidifying mode of the vehicle air conditioner 100 having the vehicle battery temperature controller 200 according to an embodiment of the present invention.

제 1 난방모드를 수행하기 위해 순환되는 냉매의 일부가 제습라인(D)을 따라 이동하도록 제 3 밸브(340)가 설치된다. 제 3 밸브(340)는 1웨이 밸브의 형태로 마련되어, 냉매가 실내 열교환기(130)로 유동하거나 유동되지 못하도록 한다.A third valve 340 is installed so that a part of the refrigerant circulated to perform the first heating mode moves along the dehumidification line D. The third valve 340 is provided in the form of a one-way valve and prevents the refrigerant from flowing into or flowing into the indoor heat exchanger 130 .

그에 따라, 제 2 팽창수단(150)에서 실외 열교환기(120)로 유동하는 냉매의 일부가 실내 열교환기(130)로 유동될 수 있다. 즉, 제 2 팽창수단(150)을 통과한 냉매의 일부는 실외 열교환기(120)로 유동되고, 나머지 일부는 실내 열교환기(130)로 유동된다.Accordingly, a portion of the refrigerant flowing from the second expansion unit 150 to the outdoor heat exchanger 120 may flow to the indoor heat exchanger 130 . That is, a part of the refrigerant that has passed through the second expansion unit 150 flows into the outdoor heat exchanger 120, and the remaining part flows into the indoor heat exchanger 130.

결과적으로 차량 내부가 난방 및 제습 됨과 동시에 배터리 히팅이 수행된다.As a result, the battery heating is performed simultaneously with heating and dehumidifying the interior of the vehicle.

The second heating mode is a heating mode performed when the outdoor temperature is below a certain temperature or defrosting of the outdoor heat exchanger 120 is concerned. For example, the constant temperature may be less than zero.

냉매는 압축기(110), 냉각수 열교환기(220), 제 2 팽창수단(150), 칠러(190), 어큐뮬레이터(170)를 통과하여 다시 압축기(110)로 순환한다.The refrigerant passes through the compressor 110, the cooling water heat exchanger 220, the second expansion unit 150, the chiller 190, and the accumulator 170 and circulates back to the compressor 110.

냉매는 제 2 팽창수단(150)을 통과한 후 냉매순환라인(R) 상에 설치된 제 4 밸브(125)에 의해 제 3 바이패스라인(R3)을 따라 유동하며 실외 열교환기(120)를 바이패스한다. 제 4 밸브(125)는 3웨이 밸브의 형태로 마련되어 제 2 팽창수단(150)을 통과한 냉매를 냉매순환라인(R) 또는 제 3 바이패스라인(R3)으로 개방할 수 있다.After passing through the second expansion unit 150, the refrigerant flows along the third bypass line R3 by the fourth valve 125 installed on the refrigerant circulation line R and bypasses the outdoor heat exchanger 120. pass The fourth valve 125 is provided in the form of a three-way valve and can open the refrigerant passing through the second expansion means 150 to the refrigerant circulation line R or the third bypass line R3.

이때, 냉매가 실외 열교환기(120)를 통과하지 않음으로 실외 열교환기(120)의 제상이 방지된다.At this time, since the refrigerant does not pass through the outdoor heat exchanger 120, defrosting of the outdoor heat exchanger 120 is prevented.

결과적으로 차량 내부가 난방 됨과 동시에 배터리(210) 히팅이 수행되며 실외 열교환기(120)의 제상이 방지된다.As a result, the battery 210 is heated at the same time as the inside of the vehicle is heated, and defrosting of the outdoor heat exchanger 120 is prevented.

도 6은 본 발명의 실시 예에 따른 차량용 배터리 온도조절장치(200)를 구비한 차량용 공조장치(100)의 제 2 난방제습모드를 도시한 구성도이다. 제 2 난방제습모드는 제 2 난방모드에서 제습이 필요한 경우 수행되는 난방모드이다.6 is a configuration diagram showing a second heating and dehumidifying mode of the vehicle air conditioner 100 having the vehicle battery temperature controller 200 according to an embodiment of the present invention. The second heating and dehumidifying mode is a heating mode performed when dehumidification is required in the second heating mode.

제 2 난방모드를 수행하기 위해 순환되는 냉매의 일부가 제습라인(D)을 따라 이동하도록 냉매의 일부를 실내 열교환기(130)로 유동시킨다.In order to perform the second heating mode, a portion of the refrigerant circulated is flowed to the indoor heat exchanger 130 so that a portion of the refrigerant moves along the dehumidifying line (D).

결과적으로 차량 내부가 난방 및 제습됨과 동시에 배터리(210)의 히팅이 수행되며 실외 열교환기의 제상이 방지된다.As a result, the inside of the vehicle is heated and dehumidified, the battery 210 is heated, and the outdoor heat exchanger is prevented from defrosting.
