Description

냉동 콘테이너 선적 화물창의 통풍 덕트 시스템{Ventilation Duct System of the Reefer Container in Hold}Ventilation Duct System of the Reefer Container in Hold}

본 발명은 냉동 콘테이너를 화물창내에 선적하는 선박의 통풍 시스템에 관한 것으로, 콘테이너 뒤쪽 냉각장치에서 발생하는 열을 화물창 밖으로 배출하기 위한 화물창 통풍용 덕트의 배치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system of a ship for loading refrigerated containers into a cargo hold, and to an arrangement of cargo hold ventilation ducts for discharging heat generated from a cooling device behind the container out of the cargo hold.

통상 냉동 콘테이너를 화물창 내에 선적함에 따라 콘테이너 뒤쪽 냉각장치(6) 부위에 열이 많이 발생하여 주위의 온도가 높게되고 결국 냉각장치의 작동에 저해 요인이 되고 있다.In general, as the refrigerated container is shipped in the cargo hold, a lot of heat is generated in the cooling device 6 at the rear of the container, and the surrounding temperature becomes high, which in turn hinders the operation of the cooling device.

상기와 같은 문제점을 해결하기 위해 종래에는 상기 냉각장치의 작동을 원활하게 하기 위하여 주위의 열을 화물창 밖으로 보내는 시스템으로, 도 1 과 같이 화물창(7) 내에 선적된 냉동 콘테이너(5)의 적재 위치마다 통풍덕트(2)를 각각 설치하였다. 그러나 상기 종래 방법은 설계 및 설치 공수 과다 투입과 많은 덕트를 설치함으로서 자재비 상승 및 선박 자체 중량이 증가되는 문제점이 있었다.In order to solve the problems as described above, in order to facilitate the operation of the cooling device, a system that sends the surrounding heat out of the cargo hold, every loading position of the refrigerated container 5 shipped in the cargo hold 7 as shown in FIG. Ventilation ducts 2 were respectively installed. However, the conventional method has a problem in that the cost of material increase and the weight of the ship itself increase due to excessive input of design and installation maneuver and installation of many ducts.

본 발명은 상기와 같은 결점을 해결하기 위해 안출된 것으로, 설계/생산공수 및 과다한 자재비 투입의 요인을 개선하기 위한 방법으로 화물창 내 콘테이너 냉각장치의 동작 적정온도인 45℃ 이하로 유지하는 조건에서 상용 열 유체 해석의 수치해석을 통한 화물창의 온도 분포를 파악하여 화물창 내 덕트 배치를 콘테이너 두 줄당 하나의 덕트를 배치하되 덕트의 길이를 짧게 하여도 콘테이너 뒤 냉각기 작동에 영향이 없는 통풍 시스템을 제공함을 목적으로 한다.The present invention has been made to solve the above-mentioned shortcomings, the method for improving the factors of design / production maneuver and excessive material cost input is commercially available under the conditions to maintain the operating temperature of 45 ° C or less of the container cooling apparatus in the cargo hold By analyzing the temperature distribution of the cargo hold through numerical analysis of the thermal fluid analysis, one duct should be arranged in two rows of container in the cargo hold, but the shortening of the length of the duct provides a ventilation system that does not affect the operation of the cooler behind the container. It is done.

The arrangement of the ducts (FIG. 3) configured by the air discharge method is arranged on the mechanical air inlet fan 9 side, and the hot air of the cargo hold 7 is naturally discharged to the ventilator 11 attached to the hatch cover wall. In addition, in the case of transporting dangerous goods, one or two ducts are arranged in the above two methods up to below the cargo hold 7 so that heavy gas can be discharged, and in particular, in the mechanical air inflow and thus the natural air discharge method (FIG. 3). Only the fan of the duct placed up to the bottom was rotated to allow ventilation.

본 발명은 도 2에 도시된 바와 같이 냉동 콘테이너(5) 선적 화물창의 기계적 공기 배출과 자연적 공기 유입 통풍 시스템에 적용된 통풍덕트의 배치는 냉동 콘테이너(5) 두줄당 하나의 통풍덕트(2)를 설치하고, 상기 통풍덕트(2)의 길이는 화물창 바닥(8)에서 상부 높이(H) 6-16미터까지 통풍덕트(2)의 끝단을 배치하였고, 도 3에 도시된 바와 같이 냉동 콘테이너(5) 선적 화물창의 기계적 공기 유입과 자연적 공기 배출 통풍 시스템에 적용된 통풍덕트의 배치는 냉동 콘테이너(5) 두줄당 하나의 통풍덕트를 설치하고, 상기 통풍덕트(2)의 길이는 화물창 바닥(8)에서 상부 높이(H) 10-20미터까지 통풍덕트의 끝단을 배치하여 구성하였다.According to the present invention, as shown in FIG. 2, the arrangement of the ventilation duct applied to the mechanical air discharge and natural air inflow ventilation system of the shipping container 5 is provided with one ventilation duct 2 per two lines of the refrigerated container 5. In addition, the length of the ventilation duct 2 is disposed at the end of the ventilation duct 2 to 6-16 meters in the upper height (H) of the cargo hold bottom (8), as shown in Figure 3 refrigerated container (5) The arrangement of the ventilation ducts applied to the mechanical cargo inlet of the cargo hold and the natural air exhaust ventilation system installs one ventilation duct per two rows of refrigerated containers (5), the length of the ventilation duct (2) being the top of the cargo hold bottom (8). The end of the ventilation duct was constructed by height (H) 10-20 meters.

상기 상태에서 공기를 화물창(7) 바닥까지 도달하게 하기 위해 덕트 하부의 스트링거(13)마다 원활히 통풍될 수 있도록 격자모양의 창살(12)을 설치하였고, 기존 덕트의 크기에 비해서 두 덕트를 한 덕트 라인으로 배치하므로 덕트의 폭을 더 넓게 하였다.In this state, a grid-shaped grate 12 was installed to allow air to reach the bottom of the cargo hold 7 at the bottom of the duct so that the air flows smoothly. The ducts were wider because they were arranged in lines.

도 2, 3에 도시된 위험물 적재시 적용되는 통풍덕트(3)는 위험물 운반시 사용되는 덕트로서 그 길이는 화물창(7) 아래까지 설치하여 그곳의 각각 오프닝에 이물질 유입으로 환풍기의 불꽃에 기인한 폭발을 막기 위해 철망을 설치하였고, 환풍기도 폭발 방지용 모터를 사용하였으며, 그 외 환풍기는 일반타입으로 적용하고 통풍덕트의 길이는 기계적 공기 유입과 자연적인 외부 공기 배출 방법 및 기계적 공기 배출과 자연적인 외부 공기 유입방법에 따라 각각 화물창 바닥에서 상부 높이까지 6-16미터, 10-20미터까지 통풍덕트의 끝단을 배치하여 화물창 내의 더운 공기를 배출하는 것이다.Ventilation duct (3) applied to the loading of dangerous goods shown in Figures 2 and 3 is a duct used for transporting dangerous goods, the length of which is installed below the cargo hold (7), due to the inflow of foreign matter into each opening there, due to the flame of the fan. The wire mesh was installed to prevent the explosion, the fan also used an explosion-proof motor, and the other fan was applied as a general type, and the length of the ventilation duct was mechanical air inflow and natural external air discharge method, mechanical air discharge and natural external air. According to the air inflow method, the end of the ventilation duct is arranged to be 6-16 meters and 10-20 meters from the bottom of the cargo hold to the upper height, respectively, to exhaust the hot air from the cargo hold.
