Description
본 고안은 에어컨(air conditioner)에 관한 것으로서, 더 상세하게는 버스(bus)나 열차(train)에 사용되는 대용량의 에어컨에 관한 것이다.The present invention relates to an air conditioner, and more particularly, to a large-capacity air conditioner used for a bus or a train.
일반적으로 냉각사이클(cooling cycle)을 이용하여 실내를 냉각시키는 에어컨은 주지하다시피 냉매(冷媒)를 압축기에서 고온, 고압으로 압축시킨 뒤 응축기(condenser)에서 액화시키고, 팽창밸브(expansion valve)를 통해 증발기(evaporator)에서 기화시켜 흡수되는 기화열에 의해 냉각작용을 수행하는 공기조절장치로, 사회전반에 걸쳐 광범위하게 사용되고 있다.In general, an air conditioner that cools a room using a cooling cycle is well known. After the refrigerant is compressed to a high temperature and a high pressure in a compressor, it is liquefied in a condenser and an expansion valve is used. An air conditioner that performs cooling by vaporization heat absorbed by evaporation in an evaporator, and is widely used throughout society.
예를들어 자동차에 있어서도 여름철 무더운 날씨에 쾌적한 차내환경을 위해 사용되고 있다. 승용차 등의 소형차량은 냉각할 공간이 좁으므로 소형의 냉각시스템(cooling system)으로도 충분하여 그 엔진에 의해 구동되나, 버스등과 같은 대형차량은 냉각할 공간이 상당히 넓기 때문에 대형의 냉각시스템이 채용되고 별도의 전용 서브엔진에 의해 구동된다.For example, in automobiles, it is used for a comfortable environment in the hot summer weather. Small vehicles such as passenger cars have a small space to cool, so a small cooling system is sufficient and driven by the engine. However, a large vehicle such as a bus has a large space to cool. And is driven by a separate dedicated sub-engine.
이에따라 대형차량의 에어컨은 그 구조상 차량의 지붕에 설치되는 것이 일반적인데, 이러한 에어컨을 특히 루프형 에어컨이라 일컫는다. 이와같은 루프형 에어컨은 차량의 지붕위로 돌출되어 설치되고 있다.Accordingly, the air conditioner of a large vehicle is generally installed on the roof of the vehicle because of its structure. Such a roof air conditioner is installed to protrude above the roof of the vehicle.
도 1에는 이와같은 버스나 기타 열차 등에 적용되고 있는 에어컨의 일반예가 도시되어 있다.1 shows a general example of an air conditioner applied to such a bus or other train.
이는, 크게 압축기(compressor;1)와, 이 압축기(1)로부터 냉매가 유입되며, 화살표로 도시된 차량의 진행 방향을 기준으로하여 진행방향 후면에 배치되는 응축기 유닛(condenser unit;2)과, 이 응축기 유닛(2)의 전면에 배치되는 증발기 유닛(evaporator unit;3)으로 대별된다.This includes a compressor (1), a refrigerant flowing from the compressor (1), and a condenser unit (2) disposed at the rear of the traveling direction on the basis of the traveling direction of the vehicle shown by the arrows; It is roughly divided into an evaporator unit 3 which is arranged in front of the condenser unit 2.
전술한 응축기 유닛(2)은, 서로 병렬 연결되는 제 1, 2 , 3, 4 응축기(2a,2b,2c,2d)를 구비하며, 서로 인접된 제 1,3 응축기(2a,2c)와 제 2, 4 응축기(2b,2d)사이에는 복수개의 응축팬(2e,2f)들이 배열 설치된다.The condenser unit 2 described above has first, second, third and fourth condensers 2a, 2b, 2c and 2d connected in parallel to each other, and the first and third condensers 2a and 2c and the first and second condensers 2a and 2c which are adjacent to each other. A plurality of condensation fans 2e and 2f are arranged between the two and four condensers 2b and 2d.
한편, 차량의 진행 방향을 기준으로하여 전면에 배치되는 증발기 유닛(3)의 구조를 보면, 서로 병렬 연결되는 제 1, 2 증발기(3a,3b)를구비하는 바, 이 제 1,2증발기(3a,3b)의 각 외면에는 하나의 모터(M)에 의해 구동되는 증발기 팬(3c,3d)가 각각 위치된다.On the other hand, when the structure of the evaporator unit 3 disposed on the front side with respect to the traveling direction of the vehicle, the first and second evaporators 3a and 3b connected in parallel to each other, the first and second evaporators ( On each outer surface of 3a, 3b, evaporator fans 3c, 3d driven by one motor M are located, respectively.
이와같은 구성을 갖는 종래 에어컨의 냉각 사이클을 설명하면 다음과 같다.Referring to the cooling cycle of the conventional air conditioner having such a configuration as follows.
먼저 압축기(1)로 부터의 고압으로 압축된 냉매는 서로 병렬 연결된 제 1, 2, 3, 4 응축기(2a,2b,2c,2d)로 각각 유입되어 액화되며, 동시에 복수개의 팽창밸브(4)를 통해 제 1, 3 응축기(2a,2c)와, 제 2, 4 응축기(2b,2d)와 연결된 제 1, 2 증발기(3a,3b)로 유입되어 기화됨으로써 이 기화열을 통해 냉각작용을 행하는 것이다.First, the refrigerant compressed by the high pressure from the compressor 1 is liquefied by flowing into the first, second, third and fourth condensers 2a, 2b, 2c, and 2d connected in parallel with each other, and at the same time, the plurality of expansion valves 4 Through the vaporization of the first and third condensers (2a, 2c) and the first and second evaporators (3a, 3b) connected to the second and fourth condensers (2b, 2d) through the vaporization heat to perform the cooling action .

셋째, 실질적으로 외기에 의해 냉각이 이루어져야 하는 응축기 유닛(2)이 증발기 유닛(3)의 후면에 위치됨으로써, 즉, 차량의 진행 방향을 기준으로하여 후면에 응축기 유닛(2)이 위치됨으로써 냉각성능의 저하를 초래하였으며, 이에따라서는 전체 에어컨의 냉각 성능을 떨어뜨리는 요인이 되었다.Third, the condenser unit 2, which is to be cooled by the outside air, is positioned at the rear of the evaporator unit 3, that is, the condenser unit 2 is positioned at the rear side with respect to the traveling direction of the vehicle, thereby cooling performance. This resulted in the deterioration of the air conditioner, which in turn reduced the cooling performance of the entire air conditioner.
