Description

차량의 냉,난방 시스템{Cooling and heating system for vehicles}Cooling and heating system for vehicles

본 발명은 차량의 냉,난방 시스템에 관한 것으로서, 특히 기존의 차량에 설치되어 있는 냉방장치를 이용하여 난방기능을 구현할 수 있도록 하므로서, 겨울철 엔진이 웜업(Warm up)되지 않은 상태에서도 난방 스위치를 켬과 동시에 뜨거운 바람이 배출됨은 물론 전체적인 난방성능의 향상의 효과를 기대할 수 있도록 한 차량의 냉,난방 시스템에 관한 것이다.The present invention relates to a cooling and heating system of a vehicle. In particular, the heating function can be implemented by using a cooling device installed in an existing vehicle, so that the heating switch is turned on even when the engine in the winter is not warmed up. At the same time, the present invention relates to a vehicle's cooling and heating system that can expect hot wind to be released as well as to improve the overall heating performance.

도 1 은 종래의 냉,난방 시스템을 도시한 것으로서,1 shows a conventional cooling and heating system,

엔진(1)과, 구동하여 냉매를 압축하는 콤프레서(2)와, 콤프레서(2)에서 압축된 냉매를 외기와 열교환시켜 냉각시키는 콘덴서(3)와, 콘덴서(3)에서 냉각된 냉매를 이용하여 차내로 송풍되는 공기를 냉각시키고 이과정에서 온도가 상승된 냉매를 다시 콤프레서(2)로 순환시키는 증발기(4)와, 냉각수 순환라인(7)을 통해 순환되는 냉각수의 열을 이용하여 차내로 공급되는 공기를 가열시키는 히터(5)와, 냉매가 순환되는 통로가 되는 냉매 순환라인(6)으로 구성된다.By using the engine 1, a compressor 2 for driving and compressing the refrigerant, a condenser 3 for cooling the refrigerant compressed by the compressor 2 by heat exchange with outside air, and a refrigerant cooled in the condenser 3, Evaporator 4 for cooling the air blown into the vehicle and circulating the refrigerant having risen in temperature to the compressor 2 and supplying it to the vehicle using the heat of the cooling water circulated through the cooling water circulation line 7 It consists of a heater 5 for heating the air to be used, and a refrigerant circulation line 6 serving as a passage through which the refrigerant is circulated.

이와같이 구성된 종래의 냉,난방 시스템은 사용자가 냉방스위치를 켤 경우, 콤프레서(2)가 동작하면서 냉매를 압축하여 냉매 순환라인(6)을 통해 배출하고, 콤프레서(2)에서 배출된 냉매는 콘덴서(3)를 통과하면서 강제 냉각되어 증발기(4)로 공급된다.In the conventional cooling and heating system configured as described above, when the user turns on the cooling switch, the compressor 2 operates to compress the refrigerant and discharge the refrigerant through the refrigerant circulation line 6, and the refrigerant discharged from the compressor 2 is a condenser ( Forced cooling while passing through 3) is supplied to the evaporator (4).

증발기(4)로 공급된 저온의 냉매는 차내로 송풍되는 공기를 냉각시키게 되므로 차내가 냉방되며, 이때 차내로 공급되는 공기를 냉각시킨 냉매는 그 온도가 상승된 상태로 다시 콤프레서(2)로 공급된 후 압축되어져 다시 순환하게 되는 것이 다.Since the low temperature refrigerant supplied to the evaporator 4 cools the air blown into the vehicle, the inside of the vehicle is cooled. At this time, the refrigerant that cools the air supplied to the vehicle is supplied to the compressor 2 again with the temperature raised. It is compressed and then cycled again.

상기 설명과 같이 냉매가 냉매순환라인(6)을 통해 콤프레서(2)→콘덴서(3)→증발기(4)의 순서로 순환하면서 차내로 공급되는 공기를 냉각시키게 되는 것이다.As described above, the refrigerant circulates through the refrigerant circulation line 6 in the order of the compressor 2, the capacitor 3, and the evaporator 4, thereby cooling the air supplied into the vehicle.

한편, 사용자가 난방스위치를 켤 경우, 히터(5)가 엔진(1) 내부를 순환하면서 온도가 상승한 냉각수를 이용하여 차내로 송풍되는 공기를 가열시키므로서 난방동작이 구현되는 것이다.On the other hand, when the user turns on the heating switch, the heating operation is implemented by heating the air blown into the vehicle by using the coolant whose temperature rises while the heater 5 circulates inside the engine 1.

그러나, 종래의 냉,난방 시스템은 냉방시스템과 난방시스템이 별도로 존재하게 되므로 설치비가 증가할 뿐만 아니라 제품의 생산성이 현저히 하락하게 되는 문제점이 있었으며, 또한, 난방시스템의 경우 겨울철에 엔진이 웜업되지 않을 경우 차내로는 차가운 공기가 유입되는 등 난방동작이 조기에 구현되지 못하는 문제점이 있었다.However, the conventional cooling and heating system has a problem that not only the installation cost increases because the cooling system and the heating system are separately present, but also the productivity of the product decreases significantly. In addition, the heating system does not warm up the engine in winter. In this case, there is a problem that the heating operation is not implemented early, such as cold air is introduced into the car.

따라서, 상기 문제점을 해결하기 위한 본 발명은 기존의 차량에 설치되어 있는 냉방장치를 이용하여 난방기능을 구현할 수 있도록 하므로서, 겨울철 엔진이 웜업되지 않은 상태에서도 난방 스위치를 켬과 동시에 뜨거운 바람이 배출됨은 물론 전체적인 난방성능이 향상되는 효과를 기대할 수 있도록 한 차량의 냉,난방 시스템을 제공함을 목적으로 한다.Therefore, the present invention for solving the above problems is to implement a heating function by using a cooling device installed in the existing vehicle, the hot wind is discharged at the same time the heating switch is turned on even when the engine is not warmed up in winter Of course, the object of the present invention is to provide a cooling and heating system for a vehicle so that the overall heating performance can be expected to be improved.

상기 도면에 의하면 본 발명은 제 1 및 제 2 3웨이밸브(11)(12), 흡열기(13), 제어부(16)로 대별 구성된다.According to the drawings, the present invention is roughly composed of first and second three-way valves 11 and 12, a heat absorber 13, and a controller 16.

상기 제 1 3웨이밸브(11)는 콤프레서(2)와 콘덴서(3) 사이의 냉방라인(18) 상에 설치하고, 이 제 1 3웨이밸브(11)의 일단에는 증발기(4)와 직접 연결되는 별도의 난방라인(17)을 형성한다.The first three-way valve 11 is installed on the cooling line 18 between the compressor 2 and the condenser 3 and directly connected to the evaporator 4 at one end of the first three-way valve 11. To form a separate heating line 17.

제 1 3웨이밸브(11)는 후설하는 제어부(16)의 제어에 따라 절환되어 냉방시에는 콤프레서(2)와 콘덴서(3)를 연결하고, 난방시에는 난방라인(18)을 통해 콤프레서(2)와 증발기(4)를 연결한다.The first three-way valve 11 is switched under the control of the control unit 16 to be installed later, and connects the compressor 2 and the condenser 3 at the time of cooling, and the compressor 2 via the heating line 18 at the time of heating. ) And the evaporator (4).

상기 제 2 3웨이밸브(11)는 증발기(4)와 콤프레서(2) 사이의 냉방라인(18) 상에 설치되는 것으로, 이 제 2 3웨이밸브(12)의 일단에 난방라인(17)이 형성되는데, 이 난방라인(17)은 후설하는 흡열기(13)를 통해 콤프레서(2)와 연결되도록 하였다.The second three-way valve 11 is installed on the cooling line 18 between the evaporator 4 and the compressor 2. The heating line 17 is provided at one end of the second three-way valve 12. It is formed, this heating line 17 is to be connected to the compressor (2) through a heat absorber (13) to be settled.

제 2 3웨이밸브(12)는 후설하는 제어부(16)의 제어에 따라 절환되어 냉방시에는 증발기(4)와 콤프레서(2)를 연결하고, 난방시에는 난방라인(18)을 통해 증발기(4)와 흡열기(13)가 연결되도록 동작한다.The second three-way valve 12 is switched under the control of the control unit 16 to be settled down so that the evaporator 4 and the compressor 2 are connected at the time of cooling, and the evaporator 4 through the heating line 18 at the time of heating. ) And the heat absorber 13 are operated.

상기 흡열기(13)는 제 2 3웨이밸브(12)와 콤프레서(2) 사이에 형성된 난방라인(17)에 설치되는데, 이 흡열기(13)는 도 2 에 도시된 바와같이 배기파이프를 감싸도록 하여 증발기(4)에서 배출되어 제 2 3웨이밸브(12)를 통해 공급되는 저온의 냉매가 배기파이프를 통과하는 고온의 배기가스에 의해 온도 상승되어 콤프레서(2)로 공급되도록 하는 것이다.The heat absorber 13 is installed in a heating line 17 formed between the second three-way valve 12 and the compressor 2, and the heat absorber 13 surrounds the exhaust pipe as shown in FIG. 2. The low temperature refrigerant, which is discharged from the evaporator 4 and supplied through the second three-way valve 12, is heated up by the high temperature exhaust gas passing through the exhaust pipe to be supplied to the compressor 2.

상기 제어부(16)는 사용자의 키이부(15) 조작에 의해 설정되는 냉방모드 또는 난방모드에 따라 상기 제 1 및 제 2 3웨이밸브(11)(12)를 절환시키는 것으로서, 냉방모드가 설정되면 제 1 및 제 2 3웨이밸브(11)(12)가 냉방라인 측으로 절환되도록 제어하고, 난방모드가 설정되면 제 1 및 제 2 3웨이밸브(11)(12)가 난방라인 측으로 절환되도록 제어하는 것이다.The controller 16 switches the first and second three-way valves 11 and 12 according to a cooling mode or a heating mode set by a user's operation of the key unit 15. When the cooling mode is set, To control the first and second three-way valves 11 and 12 to be switched to the cooling line side, and to control the first and second three-way valves 11 and 12 to be switched to the heating line side when the heating mode is set. will be.

미설명된 도면부호 14는 팽창밸브이고, 종래와 동일 구성요소에 대해서는 동일부호 처리하여 중복설명을 피했다.Unexplained reference numeral 14 denotes an expansion valve, and the same components as in the prior art are denoted by the same reference numerals to avoid duplicate explanation.

이와같이 구성된 본 발명의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

먼저, 냉방동작을 설명하면,First, the cooling operation will be described.

사용자가 키이부(15)를 조작하여 냉방모드를 설정하면, 제어부(16)는 제 1 및 제 2 3웨이밸브(11)(12)가 냉방라인 측으로 연결되도록 제어한다.When the user operates the key unit 15 to set the cooling mode, the controller 16 controls the first and second three-way valves 11 and 12 to be connected to the cooling line side.

이에따라, 콤프레서(2)에서 고온, 고압으로 압축된 냉매는 제 1 3웨이밸브(11)를 통해 콘덴서(3)로 공급되고, 콘덴서(3)로 공급된 고온, 고압의 냉매는 이 콘덴서(3)에서 외기와 열교환되어 강제 냉각된 후 증발기(4)로 공급된다.Accordingly, the refrigerant compressed to high temperature and high pressure in the compressor 2 is supplied to the condenser 3 through the first three-way valve 11, and the high temperature and high pressure refrigerant supplied to the condenser 3 is supplied to the condenser 3. ) Is forcibly heat exchanged with the outside air and forcedly cooled before being supplied to the evaporator 4.

증발기(4)로 공급된 저온의 냉매는 차내로 송풍되는 공기를 냉각시키게 되므로 차내가 냉방되며, 이때 차내로 공급되는 공기를 냉각시킨 냉매는 그 온도가 상승된 상태로 다시 콤프레서(2)로 공급된 후 압축되어져 다시 순환하게 되는 것이다.Since the low temperature refrigerant supplied to the evaporator 4 cools the air blown into the vehicle, the inside of the vehicle is cooled. At this time, the refrigerant that cools the air supplied to the vehicle is supplied to the compressor 2 again with the temperature raised. After that, it is compressed and circulated again.

상기 설명에서와 같이 냉방모드에서는 제 1 3웨이밸브(11)가 콤프레서(2)와 콘덴서(3)를 연결하고, 제 2 3웨이밸브(12)가 증발기(4)와 콤프레서(2)를 연결하므로서, 콤프레서(2)→제 1 3웨이밸브(11)→콘덴서(3)→증발기(4)→제 2 3웨이밸브(12)로 이루어지는 냉방순환라인이 형성되어 냉방기능이 정상적으로 구현되는 것이다.In the cooling mode as described above, the first three-way valve 11 connects the compressor 2 and the condenser 3, and the second three-way valve 12 connects the evaporator 4 and the compressor 2. Therefore, a cooling circulation line consisting of the compressor 2 → the first three-way valve 11 → the capacitor 3 → the evaporator 4 → the second three-way valve 12 is formed, and thus the cooling function is normally implemented.

한편, 사용자가 키이부(15)를 조작하여 난방모드를 설정하면,On the other hand, when the user operates the key unit 15 to set the heating mode,

제어부(16)는 제 1 및 제 2 3웨이밸브(11)(12)를 난방라인(17) 측으로 절환시킨다.The controller 16 switches the first and second three-way valves 11 and 12 to the heating line 17 side.

이에따라, 콤프레서(2)에서 고온, 고압으로 압축된 냉매는 제 1 3웨이밸브(11)와 난방라인(17)을 통해 증발기(4)로 직접 공급되고, 상기 증발기(4)는 고온, 고압 상태의 냉매를 이용하여 차내로 송풍되는 공기의 온도가 상승하도록 한다.Accordingly, the refrigerant compressed to high temperature and high pressure in the compressor 2 is directly supplied to the evaporator 4 through the first three-way valve 11 and the heating line 17, and the evaporator 4 is in a high temperature and high pressure state. The temperature of the air blown into the vehicle is increased by using the refrigerant.

이때, 상기 증발기(4)를 통과하면서 열을 빼앗겨 차가운 상태로 냉각된 냉매는 제 2 3웨이밸브(12)를 통해 난방라인(17)을 따라 이동하여 팽창밸브(14)를 통과하면서 팽창하고, 팽창된 저온의 냉매는 다시 흡열기(13)로 공급된다.At this time, the refrigerant cooled while being passed through the evaporator 4 and cooled in a cold state moves along the heating line 17 through the second three-way valve 12 to expand while passing through the expansion valve 14. The expanded low temperature refrigerant is again supplied to the heat absorber (13).

상기 흡열기(13)로 공급된 저온의 냉매는 배기파이프를 통과하는 고온의 배기가스로 부터 열을 흡수하여 고온의 상태로 변환되어 콤프레서(2)로 공급된다.The low temperature refrigerant supplied to the heat absorber 13 absorbs heat from the high temperature exhaust gas passing through the exhaust pipe, is converted into a high temperature state, and is supplied to the compressor 2.

흡열기(13)를 통과하면서 고온의 상태로 변환된 냉매는 콤프레서(2)에서 다시 고온, 고압의 상태로 압축되어 다시 증발기(4)로 공급되므로서 난방동작이 정상적으로 구현되는 것이다.The refrigerant converted into a high temperature state while passing through the heat absorber 13 is compressed to a high temperature and high pressure state again by the compressor 2 and supplied to the evaporator 4 again, so that the heating operation is normally implemented.

즉, 난방모드에서는 냉매가 콤프레서(2)→제 1 3웨이밸브(11)→증발기(4)→제 2 3웨이밸브(12)→팽창밸브(14)→흡열기(13)의 순서로 순환되면서 난방이 이루어지는 것이다.That is, in the heating mode, the refrigerant circulates in the order of the compressor (2) → the first three-way valve (11) → the evaporator (4) → the second three-way valve (12) → the expansion valve (14) → the heat absorber (13). The heating is done.

이상에서 설명한 바와같이 본 발명은 기존의 차량에 설치되어 있는 냉방장치를 이용하여 난방기능을 구현할 수 있도록 하므로서, 겨울철 엔진이 웜업되지 않은 상태에서도 난방 스위치를 켬과 동시에 뜨거운 바람이 배출됨은 물론 전체적인 난방성능이 향상되는 효과를 기대할 수 있으며, 냉,난방 시스템의 전체적인 구성이 비교적 단순하여 제품의 생산성 또한 향상되는 효과를 기대할 수 있도록 한 차량의 냉,난방 시스템이다.As described above, the present invention enables the heating function to be implemented by using a cooling device installed in the existing vehicle, so that the hot air is discharged at the same time as the heating switch is turned on even when the engine is not warmed up in winter, as well as the overall heating. It can be expected that the performance is improved, and the overall configuration of the cooling and heating system is relatively simple, so that the product productivity can be expected to be improved.
