Armed atmospheric troops are equipped with a lot of portable and worn items such as shields, helmets, gas guns for the suppression and protection of the body, especially in the summer season with a lot of sweat is easy to poor hygiene conditions are installed excellent air conditioning.

통상의 경찰병력 수송버스에는 버스 지붕에 쿨링유니트를 설치하는 루프 온 타입으로 하면서 냉풍토출효과를 최대로 살릴 수 있도록 하기 위하여 냉풍이 버스의 천정에서 실내 중앙으로 바로 토출하도록 하는 일명 폭포식을 채용하고 있다. 도 2는 버스 냉각시스템을 나타낸 것이다. 쿨링유니트(21a,21b,21c)는 응축기와 증발기 및 냉각팬이 하나로 이루어진 것으로서, 통상 3개가 한 대의 버스에 장착된다.In order to maximize the effect of cold air discharging, the regular police trolley bus has a roof-on type that installs a cooling unit on the roof of the bus. have. 2 shows a bus cooling system. The cooling units 21a, 21b, and 21c are composed of a condenser, an evaporator, and a cooling fan, and three of them are mounted on a single bus.

압축기(22a,22b)는 엔진(23)으로 구동시키고 있다. 엔진(23)은 기존의 버스엔진를 이용하는 방식과 보조엔진을 별도로 설치하여 운영하는 방식이 있다. 어떤 경우에도 엔진(23)에는 1대 또는 2대의 압축기(22a,22b)를 설치하여 동시에 가동시킨다. 냉매는 일반적인 순환싸이클을 따라 압축기(22a,22b)에서 고압호스(24)를 통해 쿨링유니트(21a,21b,21c)로 보내졌다가 응축 및 기화과정을 거치면서 증발되었다가 저압호스(25)를 통해 다시 압축기(22a,22b)로 귀환한다.The compressors 22a and 22b are driven by the engine 23. The engine 23 has a method of using an existing bus engine and a method of separately installing and operating an auxiliary engine. In any case, the engine 23 is provided with one or two compressors 22a and 22b and operated simultaneously. The refrigerant is sent from the compressor (22a, 22b) to the cooling units (21a, 21b, 21c) through the high pressure hose 24 in a general circulation cycle, and then evaporated through the condensation and vaporization process and then passes through the low pressure hose (25).

In a bus cooling system having a pair of compressors (3a, 3b), a compressor (4) which can be operated using a motor driven by AC power as a power source in parallel with the pair of compressors (3a, 3b) And a cutoff valve 5a, 5b at the output side of the pair of compressors 3a, 3b and the output side of the compressor 4, respectively, and the cutoff valves 5a, 5b are respectively mounted on the refrigerant line. Consists of a controller (6) to be opened and closed opposite to each other at the same time as the operation of (4).

상기에서 1쌍의 압축기(3a,3b)는 쿨링유니트(1a,1b,1c)와 고압호스(7) 및 저압호스(8)로 연결되어 있으며, 압축기(4) 또한 상기 고압호스(7)와 저압호스(8)에 각각 연결되어 있다. 하나의 컷오프 밸브(5a)는 1쌍의 압축기(3a,3b)의 출력측 고압호스(7)에 설치되어 있으며, 나머지 하나의 컷오프 밸브(5b)는 압축기(4)의 출력측 고압호스(7)에 설치되어 있다. 콘트롤러(6)는 냉각시스템을 전반적으로 제어하는 콘트롤 박스 중의 한 제어요소를 분리한 개념이다. 이 콘트롤러(6)는 압축기(4)의 가동과 동시에 1쌍의 압축기(3a,3b)측 컷오프 밸브(5a)를 폐쇄시키고, 압축기(4)측 컷오프 밸브(5b)를 개방시키는 역할을 수행한다.The pair of compressors (3a, 3b) is connected to the cooling units (1a, 1b, 1c), the high pressure hose (7) and the low pressure hose (8), the compressor (4) and the high pressure hose (7) It is connected to the low pressure hose 8, respectively. One cutoff valve 5a is provided in the output high pressure hose 7 of the pair of compressors 3a and 3b, and the other cutoff valve 5b is connected to the output high pressure hose 7 of the compressor 4. It is installed. The controller 6 is a concept in which one control element of the control box which controls the cooling system as a whole is separated. The controller 6 serves to close the pair of compressors 3a and 3b side cutoff valves 5a and open the compressor 4 side cutoff valves 5b simultaneously with the operation of the compressor 4. .

상기한 압축기(4)는 교류모터와 일체로 이루어진 것으로서 부가적으로 도시된 배전반(9)에 연결하면 교류전원이 공급되므로 가동시킬 수 있다. 또한, 압축기(4)로는 예컨대 냉동공조용으로서 10마력, 7.5kw, 최대 55,878kcal/h, 1,750rpm의 성능을 갖는 것으로 하면 본 고안의 시스템에 유효하게 적용시킬 수 있다. 이러한 압축기(4)에는 기존의 버스용 에어컨 냉매인 R134a를 함께 사용할 수 있다. 배전반(9)은 전술한 바와 같이 220V의 전력을 노상에서 차량의 배터리 부하를 줄이기 위하여 최근에 서울 시내 요소요소에 배치한 것이다.The compressor 4 is integrally formed with the AC motor and additionally connected to the distribution panel 9 shown in FIG. In addition, the compressor 4 can be effectively applied to the system of the present invention as long as it has a performance of 10 horsepower, 7.5 kw, maximum 55,878 kcal / h, 1,750 rpm, for example, for refrigeration and air conditioning. The compressor 4 may be used with R134a which is a conventional air conditioner refrigerant for a bus. As described above, the switchboard 9 is recently disposed in the element of Seoul downtown to reduce the battery load of the vehicle on the road.

따라서, 운행중에는 1쌍의 압축기(3a,3b)를 엔진(2)의 구동력에 의하여 가동시킬 수 있으므로 그 압축력에 의하여 압축된 냉매가 쿨링유니트(1a,1b,1c)에서 응축되고 기화되었다가 다시 1쌍의 압축기(3a,3b)로 귀환하는 순환싸이클을 반복하게 된다. 버스를 노변에 장시간 주차시킬 경우에는 콘트롤러(6)의 조작에 따라 압축기(4)를 가동시키면 동시에 1쌍의 압축기(3a,3b)측 컷오프 밸브(5a)는 폐쇄되고, 압측기(4)측 컷오프 밸브(5b)는 개방되어 압축기(4)에서 압축되는 냉매가 쿨링유니트(1a,1b,1c)에서 응축되고 기화되었다가 다시 압축기(4)로 귀환하는 순환싸이클을 반복하게 되는 것이다.Therefore, during operation, the pair of compressors 3a and 3b can be operated by the driving force of the engine 2, so that the refrigerant compressed by the compression force is condensed and vaporized in the cooling units 1a, 1b and 1c. The cycle of returning to the pair of compressors 3a and 3b is repeated. When the bus is parked on the roadside for a long time, the compressor 4 is operated according to the operation of the controller 6, and at the same time, the pair of compressor 3a and 3b side cutoff valves 5a are closed and the pressure gauge 4 side is pressed. The cutoff valve 5b is opened so that the refrigerant compressed in the compressor 4 is condensed and cooled in the cooling units 1a, 1b, and 1c, and vaporized, and then returned to the compressor 4.

이와 같이 구성된 본 고안은 경찰병력 수송버스가 여름철에 무장병력을 태우고 노상에서 장시간 대기할 때 교류전력에 의하여 고용량의 에어컨을 안정적으로 가동시킬 수 있기 때문에 종래와 같이 엔진을 장시간 구동함에 따른 배터리의 소모와 엔진 및 냉각시스템의 급속한 성능저하와 노후화를 방지하며 잦은 고장에 따른 수리를 하지 않아도 되는 효과가 있다.The present invention, which is configured as described above, consumes battery power by driving the engine for a long time as it is possible to stably operate a high-capacity air conditioner by AC power when the police troop transport bus burns armed forces in summer and waits for a long time on the road. This prevents rapid deterioration and deterioration of engines and cooling systems, and eliminates frequent repairs.
