UPWARD JET IMPINGING TRANSVERSE VENTILATION DUCT SYSTEM IN CONTAINERSHIP'S HOLD

摘要

The present invention relates to a structure of an upward injection ventilation duct of a cargo hold of a container ship, and an object thereof is to collect cold air introduced into a loading space through a plurality of inlets in a container ship in one upper horizontal duct to collect the cargo hold through a vertical duct. It is transported to the upper part of the container by transporting it to the lower horizontal direction duct, so that efficient ventilation is possible and its structure is simple, which saves the container ship drying labor, and maintains the internal temperature of the container below the appropriate value to overload the container freezer. To prevent.;The present invention for achieving the object is provided with a plurality of cargo hold separated from each other in the loading space of the container ship, in the duct structure for discharging the heat generated when loading the refrigerated container to the outside of the vessel, the container Installed in the upper part of the line at a predetermined interval to inject cold air into the loading space of the ship, and a plurality of air inlet provided with a ventilation suction fan to facilitate the injection of air, and separated from the cargo hold, located in the upper portion of the cargo hold, An upper horizontal duct part through which air injected through the air inlet is collected, a vertical duct part communicating with the upper horizontal duct part and extending downward along a separated space between the cargo hold and the cargo hold, and the vertical duct In communication with the part extending in the lower direction of the hold, cold air from the bottom of the hold to the inside of the hold. Technical lower point consisting of a lower horizontal duct unit processing the air injection hole to be introduced into the cargo hold through the upper horizontal duct portion from the upper portion of the container ship to discharge the air inside the cargo hold to the outside Shall be.;Refrigerated container, ventilation, ventilation duct, upward spray, cargo hold
