본 고안은 빙과류나 기타물품을 냉동운반시키는 축냉차량에 관한 것으로, 특히 냉동실 및 온도를 항상 적정한 온도로 유지시켜 냉동효율을 향상시키도록 된 보조냉각장치를 갖춘 축냉자동차에 관한 것이다.The present invention relates to a cold storage vehicle for freezing and transporting ice cream and other articles, and more particularly to a cold storage vehicle having an auxiliary cooling device to improve the freezing efficiency by maintaining the freezer compartment and the temperature at an appropriate temperature at all times.
통상 축냉차량에는 물품을 저장할 수 있는 공간이 갖추어져, 이 공간에 빙과류 내지는 이와 유사한 물품을 적재시키고서 적정한 온도를 유지시키면서 운반시킬 수 있도록 되어 있다.In general, a cold storage vehicle is provided with a space for storing an article so that ice cream or similar articles can be loaded in the space and transported while maintaining an appropriate temperature.
그러나 종래의 축냉차량은 차량이 주차한 상태(주로 야간임)에서 전기를 이용하여 대략 8시간이상 축냉시켜 탑의 내부온도가 적정한 온도로 유지되도록 하여 빙과류와 같은 물품 등을 운반하였으나, 탑의 문을 한번씩 개폐시킬 때마다 1도이상 온도가 상승되어, 여러번 문을 개폐시키게 되면 탑으 내부온도가 상승하게 되므로 빙과류와 같은 물품이 녹아 상품의 질을 저하시키게 되고 심한 경우에는 폐기처분하여야 하는 문제점이 있었다.However, in the conventional cold storage vehicle, the vehicle is parked (mainly at night) by using electricity to accumulate for more than about 8 hours so that the internal temperature of the tower is maintained at an appropriate temperature. Each time the door is opened and closed, the temperature rises by more than 1 degree, and when the door is opened and closed several times, the internal temperature of the tower rises, so that the products such as ice cream melt and degrade the quality of the product. .
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출해 낸 것으로, 탑의 문을 개폐시킴에 관계없이 축냉자동차의 탑의 내부온도를 물품의 운반 적정온도로 유지시킬 수 있도록 된 보조냉각장치를 갖춘 축냉자동차를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, and has an auxiliary cooling device that can maintain the internal temperature of the tower of the cold storage car at a proper temperature for transporting goods regardless of opening or closing the door of the tower. The purpose is to provide a cold storage car.
상기와 같은 목적을 달성하기 위한 본 고안은, 모우터압축기와, 콘덴서, 열교환기 및 드라이어에 직렬연결되면서 드라이어에 연결된 고압배관이 팽창밸브를 매개로 축냉판에 연결되는 한편, 상기 축냉판은 열교환기와 응집기 및 콘덴서와 연결된 저압배관으로 이루어진 축냉자동차의 냉각시스템이 있어서, 상기 팽창밸브와 축냉판 사이에 보조냉각기에 연결된 3방향밸브가 설치되고, 차량엔진과 연결된 보조 압축기가 고압배관과 저압배관에 연결되어 상기 보조압축기를 작동시켜 냉매를 3방향밸브를 매개로 보조냉각기로 전달시키도록 된 구조로 되어 있다.The present invention for achieving the above object, the high-pressure pipe connected to the dryer while connected in series with the motor compressor, the condenser, the heat exchanger and the dryer is connected to the cold storage plate via the expansion valve, the cold storage plate is a heat exchange There is a cooling system of a cold storage vehicle consisting of a low pressure pipe connected to a condenser and a condenser, and a three-way valve connected to an auxiliary cooler is installed between the expansion valve and the cold storage plate, and the auxiliary compressor connected to the vehicle engine is a high pressure pipe and a low pressure pipe. Is connected to the sub-compressor to operate the refrigerant to the subcooler via a three-way valve structure.
이하, 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail based on the accompanying drawings.
모우터압축기(1)가 콘덴서(2)와 열교환기(3) 및 드라이버(4)에 직렬연결되면서 이 드라이어(4)에 연결된 고압배관(5)이 팽창밸브(6)를 매개로 축냉판(7)에 연결되고, 이 축냉판(7)은 열교환기(3)와 응집기(9) 및 콘덴서(2)를 거쳐 저압배관(10)을 구성하여 모우터압축기(1)로 연결되어진 축냉자동차의 축냉장치에 있어서, 상기 팽창밸브(6)와 축냉판(7) 사이에 보조냉각기(11)와 연결된 3방향밸브(12)가 설치되고, 상기 고압배관(5)과 저압배관(10)에 차량엔진(13)과 연결된 보조압축기(14)가 연결 설치된 구조로 되어 있다.The motor compressor (1) is connected in series with the condenser (2), the heat exchanger (3) and the driver (4), and the high pressure pipe (5) connected to the dryer (4) is connected to the cold storage plate (3) through the expansion valve (6). The cold storage plate 7 is connected to the motor compressor 1 by forming a low pressure pipe 10 through a heat exchanger 3, an agglomerator 9, and a condenser 2. In the cold storage device, a three-way valve (12) connected to the subcooler (11) is installed between the expansion valve (6) and the cold storage plate (7), and the high pressure pipe (5) and the low pressure pipe (10). An auxiliary compressor 14 connected to the vehicle engine 13 is connected to the vehicle engine 13.
도면중 미설명부호 15는 탑이다.In the figure, reference numeral 15 is a tower.
한편, 상기 고압배관(5)에 연결된 축냉판(7)은 제 1 도에 도시된 바와같이 탑(15)의 전면부와 측면부 및 상면부 등에 1개 내지 4개 정도로 설치할 수 있다.On the other hand, the cold storage plate 7 connected to the high-pressure pipe (5) may be installed in about 1 to 4 or the front portion, the side portion and the upper surface portion of the tower 15, as shown in FIG.
이와같은 구조의 축냉시스템을 갖춘 본 고안은 차량이 장시간 주차에 있는 동안(주로 야간)에 모우터압축기(1)를 3상(相)220V 전원에 연결시켜 놓으면, 냉매가 압축되면서 콘덴서(2)로 보내져 열을 발산시키며, 이 고압의 냉매는 상기 고압배관(5)을 통해 열교환기(3)를 거쳐 팽창밸브(6)에 도달하게 된다.According to the present invention having a storage system of such a structure, when the motor compressor 1 is connected to a three-phase 220V power supply while the vehicle is parked for a long time (mainly at night), the refrigerant is compressed and the condenser (2) The high pressure refrigerant reaches the expansion valve (6) via the heat exchanger (3) through the high pressure pipe (5).
이 팽창밸브(6)에서 상기 냉매는 팽창확산되어 축냉판(7)을 순환하면서 주위의 열을 흡수하게 되므로 축냉판(7)이 냉각되게 되고 이와같은 냉각작용이 장시간동안(예컨대 8시간 이상)계속 진행되어 축냉판(7)의 축냉이 완료된다.In this expansion valve (6), the refrigerant is expanded and expanded to absorb the surrounding heat while circulating the cold storage plate (7), so that the cold storage plate (7) is cooled and such cooling action for a long time (e.g. 8 hours or more). Subsequently, the cold storage of the cold storage plate 7 is completed.
상기와 같은 작용으로 냉매가 축냉된 축냉판(7)을 갖춘 탑(15) 내부는 일정한 온도로 유지되어 빙과류와 같은 물품을 수송할 수 있게 되는데, 상기 탑(15)의 문(도면에 도시되어 있지 않음)을 열때마다 냉기가 새어나가 일정한 온도 이상으로 상기 탑(15)의 내부온도가 상승하게 되면 차량엔진(13)에 연결된 보조압축기(14)를 작동시키어 냉매가 상기 팽창밸브(6)와 축냉판(7) 사이에 설치된 3방향밸브(12)를 통해 보조냉각기(11)로 전달되어, 상기 보조냉각기(11)의 브로어작동에 의해 상기 탑(15) 내부의 온도를 적정한 온도까지 하강시킬 수 있으므로 빙과류와 같은 물품을 운반할 때 탑(15) 내부의 온도를 일정한 온도로 유지시킬 수 있게 된다.The inside of the tower 15 having the cold storage plate 7 in which the refrigerant is accumulated by the above-described operation is maintained at a constant temperature to transport articles such as ice cream, and the door of the tower 15 (shown in the drawing). Cold air leaks each time the internal temperature of the tower 15 rises above a certain temperature, the auxiliary compressor 14 connected to the vehicle engine 13 is operated, and the refrigerant flows with the expansion valve 6. It is transmitted to the subcooler 11 through the three-way valve 12 installed between the cold storage plate 7, and lowers the temperature inside the tower 15 to an appropriate temperature by the brower operation of the subcooler (11). It is possible to maintain the temperature inside the tower (15) at a constant temperature when carrying an article such as ice cream.
이와같은 구조로 이루어진 본 고안에 따른 축냉장치는 공지의 팽창밸브(6)와 축냉판(7) 사이에 보조냉각기(11)에 연결된 3방향밸브(12)를 설치하여 엔진(13)에 연결된 보조압축기(14)를 통해 냉매를 전달하도록 되어 있으므로 종래의 축냉차량에서 문제화되었던 탑도아의 개폐시 마다의 온도상승으로 인한 탑내부의 상승된 온도를 물품의 적정온도로 항상 유지시켜 줄 수가 있도록 되어 있다.The cold storage device according to the present invention having such a structure includes a three-way valve 12 connected to the subcooler 11 between the known expansion valve 6 and the cold storage plate 7 to be connected to the engine 13. Since the refrigerant is transferred through the compressor 14, the elevated temperature inside the tower due to the temperature rise at the time of opening and closing the top door, which is a problem in the conventional storage vehicle, can always be maintained at an appropriate temperature of the article. .
