Cooling device for ship holds

The invention relates to a cooling device for ship holds with an air cooling device and air ducts, which penetrate the hold.

It is known, in refrigerated ships, cooling devices of this type in the individual holds and in the individual To accommodate decks on the bulkheads. It has been shown, however, that this does not result in significant proportions of space can be used optimally and the length of the ship to accommodate the corresponding containers increases. It is also known to arrange the air cooling device with its units in complex winch houses and through air ducts the cooled air into the direct individual decks. With all these known measures it has been shown that a later conversion a ship to a refrigerated ship or a refrigerated container ship is very expensive and not a cheap one Use of space enables.

The object of the invention is to create a cooling device for ship holds which makes good use of space guaranteed and a subsequent installation or retrofitting of the ship according to the If necessary, made possible in a simple manner according to the modular principle. Furthermore, a device is to be created that also allows mixed loading with different containers.

According to the invention, this object is achieved in that the air cooling device is designed as a planar ventilation component and a horizontal cargo space delimitation forms, the ventilation component collecting ducts and distribution ducts for the circulation of the air has, and on the side facing the cargo space, the collecting channels have suction openings and the distribution channels are connected via openings with vertical exhaust ducts which protrude into the cargo space and which Openings are distributed over the surface of the ventilation component.

With a cooling device of this type there are the advantages that ships with the same loading capacity are considerably can be built shorter. There is also a temperature equality in the vertical. at this cooling device is created by the vertical exhaust ducts a good air distribution, so that the usual gratings can be omitted. It is possible to use open container Fiats as well as insulated refrigerated containers transport, whereby the refrigerated containers for better ventilation in their intake ports with an additional fan be equipped.

In an embodiment of the invention it is provided that the planar ventilation component is formed in the hatch cover. Through this arrangement of the ventilation component a favorable prerequisite for the subsequent installation of a cooling device is created, without affecting the cargo space. Furthermore, the possibility is created of a hatch cover accordingly to replace and optionally to carry out a normal operation and a cooling operation, whereby a good utilization of the Aggregates is created.

Alternatively, it is proposed that the sheet-like ventilation component be formed in the cargo space floor.

According to the invention, a favorable structure is created by that the hatch cover is coupled to the vertical exhaust ducts via connecting pieces.

In order to enable a good suction capacity, it is proposed that the suction openings be designed as slots are.

Favorable conditions in the hold are created in that the exhaust ducts are distributed over their length Have exhaust openings.

The drawing shows an embodiment of the invention with a sheet-like ventilation component in the hatch cover shown schematically. Show it:

Pig. 1 a file cut through a hold

with three containers arranged side by side;

Pig. 2 shows a partial longitudinal section through a hold

Pig. 3 shows a section through a complete one

Hatch cover according to line III-III of the Pig. 4;

Pig. 4 is a plan view of a hatch cover.

A ship hold 1 takes container 2 and has a hatch in the deck area which is covered by a hatch cover 3. In the hatch cover 3 is the sheet-like Ventilation component 4 arranged, which consists of a fan 6, an air cooler 7 and distribution channels 8 as well Collecting channels 9 consists. Here, the collecting channels 9 simultaneously form the suction chamber 5.

In this exemplary embodiment, the refrigeration machine is arranged separately outside the ventilation component 4. However, it is of course possible to accommodate the refrigeration machine in the ventilation component 4 in the hatch cover 3. The corresponding connection and supply lines are not shown for reasons of clarity.

The part of the ventilation component 4 facing the ship's hold 1 has a number of suction openings which are designed as slots and with the Sararael canals 9 related. The Samrael channels 9 are with the distribution channels 8 on the fan 6 and the Air cooler 7 connected and form the cooling circuit in »ventilation component 4.

The distribution channels 8 have openings 11 and are each detachably connected via a connecting piece 12 with a vertical exhaust duct 13, so that the Ventilation component 4 with the hatch cover 3 is removable.

Several blow-out ducts 13 are arranged between the containers, which have blow-out openings 14 distributed over their length. You Ausblaslcanäle 13 are expediently attached to the existing container guides and are thereby held stationary in the hold 1 of the ship. The container guides are not shown in detail.

The cooled air is brought into the ship's hold 1 via the blow-out openings 14 on the blow-out duct 13. By the exhaust openings 14, which are arranged at different heights, achieve a uniform distribution of air and pressed onto the cargo. The cold air falls down and brushes the load, which is cooled with it will. At the same time, the air in the cargo space is returned to the ventilation component 4 via the suction openings 10 and reaches the fan 6 and again via the collecting ducts 9, which are designed as suction chambers 5 the air cooler 7 back into the circuit.

Of course, this cooling circuit is also possible if the ventilation component 4 is arranged in the cargo space floor is.
