Description
본 발명은 전기자동차에 적용될 수 있는 공기조화장치에 관한 것으로서, 특히 자동차의 실내 난방시 실외측 열교환기에 성에가 끼는 것을 효과적으로 방지하여 난방효율이 증대될 수 있도록 개선된 전기자동차용 공기조화장치에 관한 것이다.The present invention relates to an air conditioner that can be applied to an electric vehicle, and more particularly, to an air conditioner for an electric vehicle that is improved so that heating efficiency can be increased by effectively preventing frost on an outdoor heat exchanger when the vehicle is heated indoors. will be.
환경보존에 관한 문제가 심각히 거론되고 있는 요즈음, 자동차에 있어서도 각종 공해를 유발시키는 종래의 가솔린자동차를 대신할 수 있는 무공해 자동차의 개발이 한창이다. 이러한 무공해 자동차 중의 하나가 전기자동차인데, 이 전기자동차에 적용되는 공기조화장치로서는, 가솔린 엔진 차량과 같이 엔진 냉각수에 의한 가열원을 얻을 수 없으므로, 가솔린 엔진 차량에 사용되고 있는 냉동 사이클에 별도의 히터를 조합한 것이 사용되거나 또는 히트 펌프(heat pump)의 원리를 이용한 것이 사용하고 있다.Nowadays, when the issue of environmental preservation is seriously discussed, the development of a pollution-free vehicle which can replace the conventional gasoline automobile which causes various pollution also in the automobile is in full swing. One of such pollution-free vehicles is an electric vehicle, and since an air conditioner applied to the electric vehicle cannot obtain a heating source by engine coolant like a gasoline engine vehicle, a separate heater is used for a refrigeration cycle used in a gasoline engine vehicle. Combinations are used or those utilizing the principle of heat pumps are used.
제1도에는 상기 히트 펌프의 원리를 이용한 전기자동차용 공기조화장치를 구조적으로 도시하였다. 도면을 참조하면, 열교환매체의 순환경로를 이루는 매체유동관(14)에는 열교환매체의 압축을 위한 압축기(13)와, 실내측 열교환기(11)와, 팽창밸브(15) 및 실외측 일교환기(12)가 직렬로 설치되어 있다.FIG. 1 structurally shows an air conditioner for an electric vehicle using the principle of the heat pump. Referring to the drawings, the medium flow pipe 14 constituting the circulation path of the heat exchange medium includes a compressor 13 for compressing the heat exchange medium, an indoor heat exchanger 11, an expansion valve 15, and an outdoor work exchanger ( 12) are installed in series.
이러한 종래 공기조화장치(10)에 있어서 자동차의 실내 난방시에는, 압축기(13)에 의해 고온고압으로 압축된 열교환매체가 매체유동관(14)내에서 화살표(A) 방향을 따라 유동하면서, 실내측 열교환기(11)와, 팽창밸브(15) 및 실외측 열교환기(12)를 차례로 거친 후, 압축기(13)내로 다시 유입되어 압축되게 된다. 한편 열교환매체는, 상술한 바와 같이 유동되는 도중에, 실내측 열교환기(11) 내에서 외부의 공기로 열을 방출하며 응축되고, 팽창밸브(15)를 거치면서 단열 팽창하게 된다. 그후 실외측 열교환기(12) 내에서 주위의 공기로부터 열을 흡수하며 증발하고, 압축기(13)로 유입된 후 압축되어 실내측 열교환기(11) 측으로 유출되는 과정을 반복하게 된다. 한괸, 상술한 바와 같이 실내측 열교환기(11) 내의 열교환매체와의 열교환을 통해 가열된 공기는, 화살표(B)로 도시한 바와 같이, 자동차의 실내로 유입되어 실내난방을 행하게 된다.In the conventional air conditioner 10, when the vehicle is heated indoors, the heat exchange medium compressed by the compressor 13 at high temperature and high pressure flows along the direction of the arrow A in the medium flow tube 14, After passing through the heat exchanger 11, the expansion valve 15, and the outdoor side heat exchanger 12, the compressor 11 is introduced into the compressor 13 and compressed. Meanwhile, as the heat exchange medium flows as described above, the heat exchange medium discharges heat into the outside air in the indoor heat exchanger 11 to condense and thermally expands while passing through the expansion valve 15. Thereafter, the heat is absorbed and evaporated from the surrounding air in the outdoor heat exchanger 12, and the process is repeated after being introduced into the compressor 13 and compressed and discharged to the indoor heat exchanger 11. However, as described above, the air heated through heat exchange with the heat exchange medium in the indoor heat exchanger 11 flows into the interior of the vehicle to perform indoor heating as indicated by arrow B. FIG.
실내 냉방시에는, 상술한 실내난방 과정과는 반대로, 압축기(13)에 의해 압축된 열교환매체가 실외측 열교환기(12) 쪽으로 유동하고 팽창밸브(15) 및 실내측 열교환기(11)를 거쳐 다시 압축기(13) 내로 유입되게 된다. 이 때, 열교환매체는 실내측 열교환기(11)를 통해 주위의 공기로부터 열을 흡수하여 증발하게 되고, 실내측 열교환기와의 열교환을 통해 냉각된 공기가 실내로 유입되어 실내 냉방을 행하게 된다.In the case of indoor cooling, the heat exchange medium compressed by the compressor 13 flows toward the outdoor side heat exchanger 12, and goes through the expansion valve 15 and the indoor side heat exchanger 11, in contrast to the above-described indoor heating process. It is again introduced into the compressor (13). At this time, the heat exchange medium absorbs heat from the surrounding air through the indoor heat exchanger 11 and evaporates, and the cooled air flows into the room through the heat exchange with the indoor heat exchanger to perform indoor cooling.
그런데, 이러한 구성을 가지는 종래 공기포화장치(10)에 있어서는, 실내 난방중에 상기 실외측 열교환기(12)를 통해 그 실외측 열교환기(12)내의 열교환매체로 열을 빼앗긴 공기 중의 수증기가 냉각됨에 따라, 실외측 열교환기 표면에 성에가 끼게 된다. 이와 같이 실외측 열교환기 표면에 성에가 끼게 되면 실외측 열교환기 내의 열교환매체와 주위 공기와의 열교환효율이 저하되게 되므로 실내 난방효율이 떨어진다는 문제점이 발생하게 된다. 또한 성에가 끼지 않더라도, 동절기에는 실외측 일교환기 주위의 온도가 상당히 낮으므로 실외측 열교환기 내의 열교환매체가 주위의 차가운 공기로부터 열을 흡수하기가 쉽지 않으므로 열교환효율이 저하된다는 문제점이 있었다.However, in the conventional air saturation device 10 having such a configuration, since the water vapor in the air deprived of heat to the heat exchange medium in the outdoor heat exchanger 12 through the outdoor heat exchanger 12 during indoor heating is cooled. Therefore, frost is formed on the surface of the outdoor heat exchanger. As described above, when frost is formed on the surface of the outdoor heat exchanger, the heat exchange efficiency of the heat exchange medium and the surrounding air in the outdoor heat exchanger is lowered. In addition, even if the frost is not, in winter, the temperature around the outdoor side heat exchanger is very low, so the heat exchange medium in the outdoor side heat exchanger is not easy to absorb heat from the cold air, there is a problem that the heat exchange efficiency is lowered.
본 발명은 이러한 문제점을 해결하기 위하여 안출된 것으로서 자동차의 실내 난방시에 실외측 열교환기의 표면에 성에가 형성되는 것을 효과적으로 억제하여 난방효율이 향상될 수 있도록 개선된 전기자동차용 공기조화장치를 제공함에 목적이있다.The present invention has been made to solve the above problems, and provides an improved air conditioner for an electric vehicle to effectively improve the heating efficiency by effectively suppressing the formation of frost on the surface of the outdoor heat exchanger when the vehicle is heated indoors. Has a purpose.
이와 같은 목적을 달성하기 위하여 본 발명에 따른 전기자동차용 공기조화장치는,In order to achieve the above object, an air conditioner for an electric vehicle according to the present invention is provided.
열교환매체 순환경로 중에 직렬로 배치되는 실내측 열교환기와 실외측 열교환기를 구비하며, 자동차의 실내 난방시에 상기 실내측 열교환기를 통과하여 자동차 실내로 유입될 공기는 그 실내측 열교환기를 통해 열교환매체로부터 열을 흡수하고 상기 실외측 열교환기를 통과하는 공기는 그 실외측 열교환기를 통해 열교환매체로 연을 방출하도록 구성된 것에 있어서,An indoor side heat exchanger and an outdoor side heat exchanger disposed in series in a heat exchange medium circulation path, and air to be introduced into the interior of the vehicle through the indoor side heat exchanger when the vehicle is heated inside is heated from the heat exchange medium through the indoor side heat exchanger. And the air passing through the outdoor side heat exchanger is configured to discharge lead through the outdoor side heat exchanger to the heat exchange medium.
자동차의 실내 난방시에 상기 실외측 열교환기를 통과할 공기를 가열하는 가열수단을 구비하여 된 점에 특징이 있다.It is characterized in that a heating means is provided for heating air to pass through the outdoor side heat exchanger when the vehicle is heated indoors.

It is preferable to comprise the radiator provided.
이하 본 발명에 따른 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안에 따른 전기자동차용 공기조화장치의 일 실시예의 개략적 구성도이다.2 is a schematic configuration diagram of an embodiment of an air conditioner for an electric vehicle according to the present invention.
도면을 참조하면 본 발명에 따른 공기조차장치(100)는, 제1도를 참조하며 설명한 종래 공기조화장치(10)와 마찬가지로, 열교환매체 순환경로를 이루는 매체유동관(14)에 직렬로 배치되는 실내측 일교환기(11)와 실외측 열교환기(12)를 구비하고 있다. 그리고, 매체유동관(14)의 실내측 열교환기(11)와 실외측 열교환기(12) 사이에는 실내측 열교환기(11)를 사이에 두고 압축기(13)와 팽창밸브(15)가 설치되어 있다.Referring to the drawings, the air even apparatus 100 according to the present invention, like the conventional air conditioner 10 described with reference to FIG. 1, is arranged in series in a medium flow pipe 14 constituting a heat exchange medium circulation path. The side work exchanger 11 and the outdoor side heat exchanger 12 are provided. The compressor 13 and the expansion valve 15 are provided between the indoor heat exchanger 11 and the outdoor heat exchanger 12 of the medium flow tube 14 with the indoor heat exchanger 11 interposed therebetween. .
한편, 실외측 열교환기(12)에 인접된 위치에는 실외측 열교환기(12)주위의 공기를 가열하기 위한 가열수단으로서 방열기(60)가 설치되어 있다. 이 방열기(60)는, 전기자동차의 동력원으로 사용되는 모터(20) 및 전력원으로 사용되는 배터리(30)를 냉각시키기 위한 냉각수의 순환경로중에 설치되어 있다. 즉 방열기(60)는 상기 냉각수가 유동되는 냉각수 유동관(40)에 접속되어, 상기 모터(20) 및 배터리(30)와의 열교환을 통해 가열된 냉각수가 방열기(60) 내부로 유입되어 그 방열기(60)를 통해 주위의 공기와 열교환을 행한 후 유출되도록 되어 있다.On the other hand, at the position adjacent to the outdoor side heat exchanger 12, a radiator 60 is provided as a heating means for heating air around the outdoor side heat exchanger 12. The radiator 60 is provided in a circulation path of cooling water for cooling the motor 20 used as a power source of an electric vehicle and the battery 30 used as a power source. That is, the radiator 60 is connected to the coolant flow pipe 40 through which the coolant flows, and the coolant heated by heat exchange with the motor 20 and the battery 30 flows into the radiator 60 and the radiator 60. After exchanging heat with the surrounding air through the
그리고, 실외측 일고환기(12)를 사이에 두고 방열기(60)와 대향되는 위치에는 공기를 흡입하기 위한 팬(70)이 모터(80)에 의해 회전 가능하게 설치되어 있다.A fan 70 for sucking air is rotatably installed by the motor 80 at a position opposite to the radiator 60 with the outdoor unitary air vent 12 interposed therebetween.
참조부호 50은 냉각수의 유동을 위한 냉각수 가압펌프이다.Reference numeral 50 is a coolant pressurized pump for the flow of coolant.
이러한 구성을 가지는 본 발명에 따른 공기조화장치(100)에 의해 자동차의 실내난방을 행하는 과정에 대해 살펴보기로 한다.With reference to the air conditioning device 100 according to the present invention having such a configuration will be described for the process of heating the interior of the car.
먼저, 압축기(13)와, 냉각수 가압펌프(50) 및 팬구동용 모터(80)를 작동시킨다. 그러면, 열교환매체는 압축기(13)에 의해 고온고압으로 압축된 후 매체유등관(14) 내에서 화살표(A) 방향을 따라 유동하며 실내측 열교환기(11)로 유입되고, 실내측 열교환기(11) 내에서 그 실내측 열교환기를 통하여 주위의 공기로 열을 방출하게 된다. 이처럼 실내측 열교환기(11) 내의 열교환매체로부터 열을 흡수하여 가열된 공기는 화살표(B)로 도시한 바와 같이 자동차 실내로 유입되어 실내 난방을 행하게 된다. 그리고, 실내측 열교환기(11)내에서 주위의 공기로 열을 빼앗겨 응축된 열교환매체는 팽창밸브(15)를 거쳐 실외측 열교환기(12)로 유입되고, 그 실외측 열교환기(12) 내에서 주위의 공기로부터 열을 흡수하여 증발한 후 압축기(13)로 유입되게 된다.First, the compressor 13, the cooling water pressurizing pump 50, and the fan driving motor 80 are operated. Then, the heat exchange medium is compressed to a high temperature and high pressure by the compressor 13, flows in the direction of the arrow A in the medium duct 14 and flows into the indoor heat exchanger 11, the indoor heat exchanger ( 11) heat is released into the surrounding air through the indoor heat exchanger. As such, the air heated by absorbing heat from the heat exchange medium in the indoor heat exchanger 11 flows into the vehicle interior as shown by arrow B to perform indoor heating. Then, the heat exchange medium condensed by the heat from the ambient air in the indoor heat exchanger (11) flows into the outdoor heat exchanger (12) through the expansion valve (15), and in the outdoor heat exchanger (12). After absorbing heat from the surrounding air in the evaporation it is introduced into the compressor (13).
한편, 상기 펌프(50)의 작동에 의해, 모터(20) 및 배터리(30)로부터 열을 흡수한 냉각수가 냉각수유동관(40) 내에서 유동하며 방열기(60)를 거치게 되는데 방열기(60)로 유입된 냉각수는 그 방열기(60)를 통해 주위의 공기와 열교환을 행하여 냉각되면서 주위의 공기를 가열하게 된다. 이처럼 가열된 공기는 모터(80)에 의해 회전되는 팬(70)에 의해 화살표(C) 방향으로 즉 실내측 열교환기(11) 측으로 유동되게 된다. 이처럼 방열기(60)에 의해 가열되어 팬(70)에 의해 실외측 열교환기(12)쪽으로 유동되는 공기가, 상술한 바와 같이 실외측 열교환기(12)를 통해 그 실외측 열교환(12)기 내의 열교환매체와 열교환을 행하게 된다. 따라서 실외측 열교환기(12) 내의 열교환매체는 방열기(60)에 의해 가열되어 있는 공기로부터 증발잠열을 흡수하게 되므로, 증발잠열이 흡수가 용이하여 열교환효율이 향상될 수 있게 된다. 또한, 종래 공기조화장치(10)에 있어서 실외측 열교환기 주위의 공기가 냉각됨으로써 그 실외측 열교환기의 표면에 성에가 형성되던 것과는 달리, 본 발명에 따른 공기조화장치(100)에 있어서는 실외측 열교환기(12)주위의 공기가 상기 방열기(60)에 의해 가열되어 있으므로, 실외측 열교환기(12)의 표면에 성에가 끼는 것이 효과적으로 억제될 수 있게 되어 난방효율이 증대되게 된ㄷ다.On the other hand, by the operation of the pump 50, the cooling water absorbed heat from the motor 20 and the battery 30 flows in the coolant flow pipe 40 and passes through the radiator 60, the inlet to the radiator 60 The cooled water is cooled by performing heat exchange with the surrounding air through the radiator 60 to heat the surrounding air. The heated air is flowed in the direction of the arrow (C), that is to the indoor heat exchanger 11 by the fan 70 rotated by the motor 80. In this way, the air heated by the radiator 60 and flowed to the outdoor heat exchanger 12 by the fan 70 in the outdoor heat exchanger 12 through the outdoor heat exchanger 12 as described above. Heat exchange with the heat exchange medium is performed. Therefore, since the heat exchange medium in the outdoor heat exchanger 12 absorbs the latent heat of evaporation from the air heated by the radiator 60, the latent heat of evaporation is easily absorbed, thereby improving heat exchange efficiency. In addition, in the conventional air conditioner 10, the air around the outdoor heat exchanger is cooled, so that frost is formed on the surface of the outdoor heat exchanger. Since air around the heat exchanger 12 is heated by the radiator 60, frost on the surface of the outdoor heat exchanger 12 can be effectively suppressed, thereby increasing heating efficiency.
한편, 상술한 종래 공기조화장치에 있어서와 마찬가지로, 본 발명에 따른 공기조화장치(100)에 있어서 냉방시에는 상기 실외측 열교환기(12)내의 열교환매체가 그 실외측 열교환기(12) 주위의 공기로 열을 방출하게 되며 그 공기의 온도가 낮을수록 열교환효율이 향상되게 되므로, 방열기(60)에 의해 가열된 공기가 실외측 열교환기(12) 쪽으로 유동되지 않도록 팬구동용 모터(80)의 작동을 정지시킨다. 이와 같이 하게 되면, 방열기(60)에 의해 가열된 공기에 의해 실외측 열교환기(12) 주위의 공기가 더워지는 것을 방지할 수 있다. 한편, 예를 들어 방열기(60)에 의해 가열된 공기의 유출경로로서, 상기 실외측 열교환기(12)를 통하는 제1경로와 실외측 열교환기(12)를 비켜가는 제2경로를 형성하고 상기 경로들을 선택적으로 개폐하는 도어를 설치함으로써, 방열기에 의해 가열된 공기의 상기 실외측 열교환기로의 유동을 상기 도어의 작동에 의해 제어하도록 할 수도 있을 것이다.On the other hand, as in the conventional air conditioner described above, in the air conditioner 100 according to the present invention, during cooling, the heat exchange medium in the outdoor heat exchanger 12 is formed around the outdoor heat exchanger 12. Since the heat is released to the air and the temperature of the air is lower, the heat exchange efficiency is improved, so that the air heated by the radiator 60 does not flow toward the outdoor heat exchanger 12. Stop operation In this way, it is possible to prevent the air around the outdoor heat exchanger 12 from being heated by the air heated by the radiator 60. On the other hand, for example, as an outflow path of air heated by the radiator 60, a first path through the outdoor heat exchanger 12 and a second path away from the outdoor heat exchanger 12 are formed and By installing a door that selectively opens and closes paths, it may be possible to control the flow of air heated by the radiator to the outdoor side heat exchanger by operation of the door.
이상에서 살펴본 바와 같이 본 발명에 따른 전기자동차용 공기조화장치는, 자동차의 실내 난방시에 실외측 열교환기를 통해 그 실외측 열교환기 내의 열교환매체로 열을 제공할 공기가 미리 가열되도록 되어 있으므로, 실외측 열교환기 표면에 성에가 끼는 것이 효과적으로 억제될 수 있으므로 난방효율이 향상될 수 있다.As described above, the air conditioner for an electric vehicle according to the present invention is configured to heat the air to provide heat to the heat exchange medium in the outdoor heat exchanger through the outdoor heat exchanger when the vehicle is heated indoors. Defrosting on the surface of the side heat exchanger can be effectively suppressed, so that the heating efficiency can be improved.
