이하에서는 첨부된 도면을 참조하여, 본 발명에 따른 냉동탑차용 냉동시스템의 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the refrigeration tower vehicle refrigeration system according to the present invention.

도 1에는 본 발명에 의한 냉동탑차용 냉동시스템이 설치되는 냉동탑차(1)의 정면도가 도시되어 있다.1 is a front view of a refrigeration tower (1) equipped with a refrigeration system for a refrigeration tower according to the present invention.

도 1을 참조하면, 본 발명에 의한 냉동탑차(1)는 일반 화물용 트럭의 프레임을 가지며, 후방에 냉동고(30)가 적재된다. 그리고, 운전석의 상부의 실외에는 본 발명에 의한 냉동탑차용 냉동시스템의 전동부품 등이 설치되는 냉동유닛(20)이 설치된다.Referring to Figure 1, the refrigeration tower (1) according to the present invention has a frame of a truck for general cargo, the freezer (30) is loaded on the rear. In addition, the outdoor unit in the upper part of the driver's seat is provided with a refrigeration unit 20 in which the electric parts and the like of the refrigeration tower vehicle refrigeration system according to the present invention are installed.

도 2는 본 발명에 의한 냉동탑차용 냉동시스템을 보인 개념도이다. 도 2를 참조하면, 본 발명에 의한 냉동탑차용 냉동시스템은 엔진실, 냉동유닛(20), 냉동고(30)의 고내에 각각 나뉘어 설치된다.Figure 2 is a conceptual diagram showing a refrigeration system for a refrigeration tower according to the present invention. Referring to Figure 2, the refrigeration tower refrigeration system according to the present invention is installed divided into the engine compartment, the refrigeration unit 20, the freezer 30, respectively.

엔진실은 차량의 엔진실을 의미하는 것으로, 엔진실에 설치된 엔진(10)이 구동되면, 이 엔진(10) 회전축의 회전력에 의해 발전기(13)가 구동되어 발전기(13)에서 전기가 생산된다.The engine compartment means an engine compartment of a vehicle. When the engine 10 installed in the engine compartment is driven, the generator 13 is driven by the rotational force of the rotation shaft of the engine 10 to generate electricity in the generator 13.

발전기(13)에서 생산된 전기는 전력선을 따라 충전기(15)로 보내져 충전기(15)에서는 전기에너지가 저장된다.The electricity produced by the generator 13 is sent along the power line to the charger 15 so that the electric energy is stored in the charger 15.

냉동유닛(20)에는 DC모터(21) 및 이 DC모터(21)에 의해 구동되는 압축기(23) 등이 설치된다. DC모터(21)는 충전기(15)에 저장된 전기에너지를 받아 회전축의 회전력을 발생시키며, 이 회전축과 압축기(23)가 연결되어 압축기(23)가 구동된다.The refrigeration unit 20 is provided with a DC motor 21 and a compressor 23 driven by the DC motor 21. The DC motor 21 receives electric energy stored in the charger 15 to generate rotational force of the rotating shaft, and the rotating shaft and the compressor 23 are connected to drive the compressor 23.

한편, 압축기(23)는 냉매사이클을 이루는 한 부품으로서, 냉매사이클은 압축기(23), 응축발전기(25), 보조응축기(26), 팽창밸브(31), 증발기(37)를 통해 냉매가 순환하도록 구성된다.Meanwhile, the compressor 23 is a component constituting the refrigerant cycle, and the refrigerant cycle circulates through the compressor 23, the condensation generator 25, the auxiliary condenser 26, the expansion valve 31, and the evaporator 37. It is configured to.

도 2에 도시된 바와 같이, 팽창밸브(31)와 증발기(37)는 냉동고(30)에 설치되고, 압축기(23)와 응축발전기(25), 보조응축기(26)는 냉동유닛(20)에 설치된다.As shown in FIG. 2, the expansion valve 31 and the evaporator 37 are installed in the freezer 30, the compressor 23, the condensation generator 25, and the auxiliary condenser 26 are connected to the refrigeration unit 20. Is installed.

압축기(23)는 냉매를 고온 고압으로 압축하여 응축발전기(25)로 보낸다. 응축발전기(25)는 내부에 임펠러(미도시)를 설치하여 고온 고압의 냉매가 응축발전기(25)를 지나는 힘에 의해 임펠러가 돌게 되고, 이 회전력을 전기에너지로 변환한다. 응축발전기(25)는 충전기(15)와 연결되어, 생산한 전기에너지를 충전기(15)에 저장한다.The compressor 23 compresses the refrigerant to high temperature and high pressure and sends the refrigerant to the condensation generator 25. The condenser generator 25 has an impeller (not shown) installed therein so that the impeller turns by the force of the high temperature and high pressure refrigerant passing through the condenser generator 25, and converts the rotational force into electrical energy. The condensation generator 25 is connected to the charger 15, and stores the produced electrical energy in the charger 15.

응축발전기(25)는 내부에 임펠러가 설치된 것 이외에도 냉동시스템의 압축기(23)보다 크기가 작은 보조압축기를 이용할 수 있다. 이 보조압축기를 일반적인 냉매 순환방향과 반대방향으로 설정하여 설치하면, 냉매의 압축력이 다소 소진될 수 있으나, 이 보조압축기로서의 응축발전기(25)에서 열교환이 일어나면서 냉매가 응축되는 동시에 전기에너지가 생산된다.The condenser generator 25 may use an auxiliary compressor having a smaller size than the compressor 23 of the refrigeration system in addition to the impeller installed therein. If the auxiliary compressor is set in a direction opposite to the general refrigerant circulation direction, the compressive force of the refrigerant may be somewhat consumed. However, the heat is generated in the condensation generator 25 as the auxiliary compressor, and the refrigerant is condensed, and electrical energy is produced. do.

또한, 내부에 임펠러가 설치된 형식의 응축발전기(25)에서도 냉매의 압축력이 다소 소진될 수 있으나, 전기에너지가 생산되므로 이 생산된 에너지는 재활용이 가능하다.In addition, although the compression force of the refrigerant may be somewhat consumed even in the condenser generator 25 having an impeller installed therein, since the electric energy is produced, the produced energy may be recycled.

응축발전기(25) 내부에서는 임펠러를 통과하면서 열교환이 이루어져 냉매의 상당부분이 응축되는 효과를 얻을 수 있다.Inside the condensation generator 25, heat exchange is performed while passing through the impeller, so that a substantial portion of the refrigerant may be condensed.

또한, 이 응축발전기(25)를 통과한 냉매는 보조응축기(26)로 보내진다. 응축발전기(25)의 응축효과가 미진한 경우를 대비하여 기존의 응축기보다 소형의 응축기를 설치하는 것이다. 이 경우, 보조응축기(26)로 냉매를 보내지 않고 응축발전기(25)와 팽창밸브(31)로 직접 연결되는 바이패스관(미도시) 및 이 바이패스관에 설치되는 밸브를 설치하여, 응축효과가 많이 필요한 여름철에는 보조응축기(26)를 사용하고, 기온이 낮아 응축효과가 많이 필요하지 않은 겨울철에는 보조응축기(26)를 사용하지 않고 응축발전기(25)에서 바로 팽창밸브(31)로 냉매를 보내는 방법도 사용할 수 있다.In addition, the refrigerant passing through the condenser generator 25 is sent to the auxiliary condenser 26. It is to install a smaller condenser than the existing condenser in case the condensation effect of the condenser generator 25 is insignificant. In this case, a bypass pipe (not shown) connected directly to the condensation generator 25 and the expansion valve 31 and a valve installed in the bypass pipe are installed without sending a refrigerant to the auxiliary condenser 26, thereby providing a condensation effect. In the summer, when the secondary condenser 26 is used, and in the winter when the temperature is low and the condensation effect is not necessary, the secondary condenser 26 is not used and the refrigerant is directly transferred from the condenser generator 25 to the expansion valve 31. You can also use the sending method.

냉동고(30)에는 통상적인 경우와 같이, 팽창밸브(31)와 증발기(37)가 설치되어 증발기(37)에서 냉매가 기화하는 기화열에 의해 고내의 온도를 떨어트릴 수 있게 된다.As in the conventional case, the freezer 30 is provided with an expansion valve 31 and an evaporator 37 to reduce the temperature in the refrigerator by the heat of vaporization of the refrigerant in the evaporator 37.

개폐부(24)는 하우징(22)의 전면부를 밀폐 또는 개방시켜, 개폐부(24)를 열면 외부의 공기가 냉동유닛(20) 내부로 들어와서 후면의 배기공(28)으로 빠져나가게 된다. 차량의 정차 시에는 개폐부(24)를 여는 효과가 크지 않으나 차량의 이동 시에는 개폐부(24)를 통해 외부의 공기가 빠른 속도로 들어오게 된다.The opening and closing part 24 seals or opens the front part of the housing 22, and when the opening and closing part 24 is opened, external air enters into the refrigerating unit 20 and exits into the exhaust hole 28 at the rear side. When the vehicle is stopped, the effect of opening the opening and closing part 24 is not great, but when the vehicle moves, the outside air enters at a high speed through the opening and closing part 24.

개폐부(24)가 닫힌 경우에는 배기공(28)을 통해서만 제한적으로 외부의 공기가 유통된다.When the opening and closing portion 24 is closed, the outside air flows through the exhaust hole 28 on a limited basis.

하우징(22) 내부에는 전술한 바와 같이, DC모터(21), 압축기(23), 응축발전기(25), 보조응축기(26)가 설치된다.As described above, the housing 22 is provided with a DC motor 21, a compressor 23, a condensation generator 25, and an auxiliary condenser 26.

또한, 하우징(22) 내부에는 열교환을 돕기 위한 송풍장치(29)가 설치된다. 송풍장치(29)는 하우징(22) 내부의 중앙에 설치되고, 송풍장치(29)의 한 쪽에는 DC모터(21)와 압축기(23)가 설치되고, 송풍장치(29)의 다른 한 쪽에는 응축발전기(25)와 보조응축기(26)가 설치된다.In addition, a blower 29 is installed inside the housing 22 to assist heat exchange.

송풍장치(29)는 일반적인 팬과 모터를 이용한 것으로 정역회전이 가능하도록 구성하여 정회전과 역회전의 회전 방향에 따라 공기를 DC모터(21)와 압축기(23) 방향으로 보내거나 또는 공기를 응축발전기(25)와 보조응축기(26) 방향으로 보낼 수 있게 한 것이다.The blower 29 uses a general fan and a motor, and is configured to enable forward and reverse rotation so that air is directed toward the DC motor 21 and the compressor 23 according to the rotational direction of the forward and reverse rotation, or condensed air. The generator 25 and the auxiliary condenser 26 is to be sent to.

기온이 떨어지는 겨울철에는 압축기(23)가 너무 차가워지면 효율이 떨어지므로 도 3에 도시한 바와 같이, 개폐부(24)를 닫고 송풍장치(29)를 응축발전기(25) 및 보조응축기(26) 쪽에서 DC모터(21)와 압축기(23) 방향으로 공기가 진행하도록 구동시키면, 응축발전기(25) 쪽의 따뜻한 공기가 압축기(23) 쪽으로 갈 수 있게 되어 효율이 향상된다.Since the compressor 23 is too cold in winter when the temperature is low, the efficiency decreases. As shown in FIG. 3, the opening and closing unit 24 is closed and the blower 29 is connected to the condenser generator 25 and the auxiliary condenser 26. When the air is driven in the direction of the motor 21 and the compressor 23, the warm air on the condensation generator 25 side can go to the compressor 23, and the efficiency is improved.

반면에 기온이 올라가는 여름에는 도 4에 도시한 바와 같이, 압축기(23) 및 DC모터(21)의 과열을 피해야 한다. 따라서, 이 경우에는 개폐부(24)를 열고 송풍장치(29)를 DC모터(21)와 압축기(23) 쪽에서 응축발전기(25) 및 보조응축기(26) 쪽으로 보내주는 것이 유리하다. DC모터(21)와 압축기(23)의 과열을 방지하면서도, 응축발전기(25) 및 보조응축기(26) 내부의 원활한 열교환을 도울 수 있기 때문이다.On the other hand, in summer when the temperature rises, overheating of the compressor 23 and the DC motor 21 should be avoided. Therefore, in this case, it is advantageous to open the opening and closing part 24 and to send the blower 29 toward the condensation generator 25 and the auxiliary condenser 26 from the DC motor 21 and the compressor 23. This is because while preventing overheating of the DC motor 21 and the compressor 23, it is possible to help smooth heat exchange in the condenser generator 25 and the auxiliary condenser 26.

이상과 같은 구조를 갖는 본 발명에 의한 냉동탑차용 냉동장치는 응축발전기(25)가 설치되므로 응축과 동시에 발전이 가능하여 에너지 효율을 높이고 냉동유닛(20)의 크기를 줄일 수 있게 된다.The refrigeration tower refrigeration apparatus according to the present invention having the structure as described above is installed because the condensation generator 25 can be condensed at the same time can increase the energy efficiency and reduce the size of the refrigeration unit (20).

또한, 기온이 높은지 낮은지에 따라 냉동유닛(20)의 개폐부(24)를 개폐함으로써, 냉동사이클의 효율을 높이고 냉동유닛(20)을 구성하는 부품들의 내구성을 향상시킬 수 있게 된다.In addition, by opening and closing the opening and closing portion 24 of the refrigeration unit 20 according to whether the temperature is high or low, it is possible to increase the efficiency of the refrigeration cycle and improve the durability of the components constituting the refrigeration unit (20).
