Description

  The present invention relates to a structure of a ventilation duct for ventilating a cargo compartment of a car carrier having a multi-layer vehicle loading deck.

In an automobile carrier ship having a multi-layer vehicle loading deck represented by a roll-on / roll-off ship (so-called RORO ship), not only when a vehicle is loaded and unloaded, but also during operation, a worker or a driver frequently Often enters the cargo compartment where is loaded. Therefore, ventilation equipment for ventilating the cargo compartment formed on the multi-layer vehicle loading deck is indispensable equipment for such an automobile carrier.
Regarding the ventilation equipment structure of an automobile carrier ship having such a plurality of vehicle loading decks, the applicant of the present application is disclosed in Japanese Patent Application Laid-Open No. 2006-15933 (Japanese Patent Application No. 2004-197578 “Ventilation equipment structure or exhaust equipment of an automobile carrier ship”). Structure ") has already been proposed.

What is disclosed in JP-A-2006-15933 has the following structure.
FIG. 5 shows an outline of a structure of a ventilation duct for ventilating a cargo compartment of an automobile carrier having a multi-layer vehicle loading deck disclosed in Japanese Patent Application Laid-Open No. 2006-15933. In the ventilation facility for ventilating the cargo compartment of an automobile carrier having a multi-layer vehicle loading deck, the air supply / exhaust facility includes an intake duct 42 installed on the exposed deck and a blower connected to the lower end of the intake duct 44 and a plurality of air supply / exhaust ducts 31, 32, 33, 34,... Connected to the lower end of the blower and penetrating the multilayered vehicle loading deck, respectively. , 33, 34,... Are in order from the first (n-1) th air supply / exhaust duct 31 that penetrates the exposed deck, the second air supply / exhaust duct 32 that penetrates the first deck, and the top. Instep N-th air supply / exhaust duct (n ≧ 3) is formed, and the lower end of each opening of the n-th air supply / exhaust duct is separated from the n-th deck below the open end and can be sucked and exhausted around the four sides. The horizontal cross sections of the air supply / exhaust ducts are substantially similar to each other, and the horizontal cross sectional area of the (n-1) th air supply / exhaust duct is larger than the horizontal cross sectional area of the nth air supply / exhaust duct. And the projection figure to the horizontal surface of the said (n-1) th air supply / exhaust duct has a structure which includes the projection figure to the horizontal surface of the said nth air supply / exhaust duct.

  In such a structure, when the blower 44 is activated, outside air flows in from the intake duct 42 in a flow as indicated by an arrow c, and is sent downward in the first air supply / exhaust duct 31 as indicated by an arrow d1. The outside air further flows into the second air supply / exhaust duct 32 and is sent downward. However, the projected graphic of the first air supply / exhaust duct 31 protrudes from the projected graphic of the second air supply / exhaust duct 32. Therefore, the outside air corresponding to the protruding portion flows out into the first deck 62. On the other hand, the outside air corresponding to the projection figure of the second air supply / exhaust duct 32 has the air blowing variable louver 38 fully open, that is, the direction of the louver of the air blowing variable louver 38 is vertical, so that the wind speed does not decrease and remains as it is. 2 flows into the second air supply / exhaust duct 32. The same phenomenon occurs when the blown outside air flows from the second air supply / exhaust duct 32 to the third air supply / exhaust duct 33 and from the third air supply / exhaust duct 33 to the fourth air supply / exhaust duct 34. All the outside air that is generated and sent to the fourth air supply / exhaust duct 34 is configured to flow into the fourth deck 65.

By adopting such a structure, disclosed in Japanese Patent Application Laid-Open No. 2006-15933 is “the supply / exhaust structure of a ventilation facility of an automobile carrier ship” (1) Since the lower air supply / exhaust duct has a protruding portion at the separated portion, the outside air can be supplied uniformly from all directions, or the air can be uniformly taken in from all directions, and the ventilation efficiency is increased. (2) The amount of outside air supplied to each vehicle loading deck can be easily calculated, and the air volume distribution to each vehicle loading deck can be reliably performed. (3) Moreover, since the air expelled from the separation part is blown downward, the loaded vehicle is not directly exposed to the outside air, and the commercial value of the loaded vehicle is not lowered. (4) At the time of outfitting, the air supply / exhaust ducts are separated from each other, and the cross section of the air supply / exhaust duct located in the lower part is smaller than the air supply / exhaust duct located in the upper part. Even if it does not exist, there exists an effect of being able to attach an air supply / exhaust duct at a previous process.
No. 2006-15933
