Abstract
Description
Die Erfindung betrifft ein Umluftsystem für ortsgebundene Lagerräume und für Laderäume von Kühlschiffen mit Hochregallagern für gestapeltes oder palettiertes Gut. Ein solches Umluftsystem ist zum Beispiel aus der Druckschrift
Umluftsysteme in den Laderäumen von Kühlschiffen haben die Aufgabe, die Ladung mit gekühlter Luft zu umspülen und somit auch den gesamten Laderaum zu kühlen.Air circulation systems in the cargo hold of refrigerated ships have the task of circulating the cargo with cooled air and thus also cooling the entire cargo space.
Der Qualitätserhalt der Ladung während des Transportes bedingt eine möglichst konstante Raumtemperatur und eine saubere Laderaumatmosphäre. Dieses gilt insbesondere bei Fruchtfahrten. Hier soll das Umluftsystem nicht nur die Temperatur übertragen, sondern auch die Reifungswärme der Früchte und somit die Entwicklung von Reifungsgasen, wie CO2, Acetylen, Ethylen, usw., aufnehmen. Das setzt wiederum voraus, dass die Ladung wirklich in allen Lagen ausreichend von Kühlluft umspült wird.The quality of the cargo during transport requires a constant room temperature and a clean cargo room atmosphere. This applies in particular to fruit trips. Here, the air circulation system should not only transmit the temperature, but also absorb the heat of maturation of the fruit and thus the development of maturing gases such as CO 2 , acetylene, ethylene, etc. This, in turn, requires that the cargo is really sufficiently bathed in cooling air in all positions.
In den Standardkühlschiffen wird zumeist mit einem Luftweg durch die Ladung von etwa zwei bis drei Meter gerechnet. In diesen Bereichen sind die Luftwege durch Kanalführungen usw. sehr gut zu kontrollieren. Auch liegen für diese Systeme ausreichende Erfahrungen vor. Hochregallager an Bord von Schiffen, insbesondere für den Transport von Früchten, sind aufgrund ihrer Konstruktion wesentlich schwieriger kontrolliert zu durchlüften.In the standard cooling vessels, an airway through the cargo of about two to three meters is usually expected. In these areas, the airways through ducts, etc. are very easy to control. There is also sufficient experience for these systems. High-bay warehouses on board ships, especially for the transport of fruit, are much more difficult to ventilate due to their construction.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Umluftsystem für ortsgebundene Lagerräume und für Laderäume von Kühlschiffen mit Hochregallagern für gestapeltes oder palettiertes Gut zu schaffen, mit dem gewährleistet ist, dass die Ladung unter Aufrechterhaltung einer konstanten Kühltemperatur in allen Lagen umfassend von Kühlluft umspült wird.It is therefore an object of the present invention to provide a recirculation system for stationary storage rooms and cargo holds of reefers with high-bay storage for stacked or palletized Good, with the it is ensured that the charge is completely surrounded by cooling air while maintaining a constant cooling temperature in all positions.
Gelöst wird diese Aufgabe mit einem Umluftsystem für ortsgebundene Lagerräume und für Laderäume von Kühlschiffen mit Hochregallagern für gestapeltes oder palettiertes Gut mit den im Anspruch 1 angegebenen Merkmalen.This object is achieved with a recirculation system for stationary storage rooms and cargo holds of reefers with high-bay warehouses for stacked or palletized goods with the features specified in claim 1.
Hiernach besteht das erfindungsgemäße Umluftsystem darin, dass in dem Lagerraum oder dem Laderaum eines Kühlschiffes im Bereich eines jeden Regallagers zwei übereinanderliegende Luftkreisläufe zur Kühlung der Ladung und des Laderaumes ausgebildet sind, wobei in dem Laderaum mindestens ein Regallager, bevorzugterweise zwei Regallager, angeordnet sind und wobei jedem Regallager ein Schacht für das Stapelfahrzeug zugeordnet ist oder zwischen den beiden Regallagern ein Schacht für das Stapelfahrzeug angeordnet ist, wobei der Schacht als gemeinsame Druckverteilkammer der Zuluft für jedes Regallager dient.Thereafter, the recirculation system according to the invention is that in the storage room or the hold of a refrigerated ship in the region of each shelf storage two superimposed air circuits are designed to cool the cargo and the load compartment, wherein in the cargo space at least one shelf storage, preferably two rack storage, are arranged and each shelf storage a shaft for the stacking vehicle is assigned or between the two shelf storage a shaft for the stacking vehicle is arranged, wherein the shaft serves as a common pressure distribution chamber of the supply air for each shelf storage.
Danach zeichnet sich das Hochregallager in einem Lagerraum oder an Bord von Schiffen dadurch aus, dass vor jedem Regallager ein Schacht für das Stapelfahrzeug vorhanden und freibleibend sein muss. Dieser Schacht wird für das Umluftsystem als Luftverteilschacht benutzt.Thereafter, the high-bay warehouse in a storage room or on board ships is characterized by the fact that before each shelf storage a shaft for the stacking vehicle must be present and subject to change. This shaft is used for the air circulation system as air distribution shaft.
Das erfindungsgemäße Luftführungssystem besteht hiernach aus zwei übereinander angeordneten Luftkreisläufen. Jeder dieser Luftkreisläufe durchläuft einen Luftkühler mittels der Leistung von Ventilatoren, der auf der gegenüberliegenden Seite des Schachtes von dem Regallager angebracht ist.The air duct system according to the invention consists hereinafter of two superimposed air circuits. Each of these air circuits passes through an air cooler by means of the power of fans, which is mounted on the opposite side of the shaft of the shelf storage.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the dependent claims.
So mündet die Zusammenführung der beiden übereinanderliegenden Luftkreisläufe vor der Ansaugseite der übereinander angeordneten Luftkühler. Jeder der Luftkreisläufe durchläuft einen Luftkühler mittels der Leistung von Ventilatoren, die auf der gegenüberliegenden Seite des Schachtes vor dem Regallager angebracht sind.Thus, the merging of the two superposed air circuits opens in front of the suction side of the superposed air cooler. Each of the air circuits passes through an air cooler through the power of fans mounted on the opposite side of the shaft in front of the shelf storage.
Die Luftführung ist dabei derart, dass für die oberen Luftkreise die Luftkühler vertikal nach oben durchströmt werden, wobei die Luft über einen Deckenkanal in den Schacht geleitet wird. Die Bodenwände dieses Deckenkanals sind mit Luftaustrittsöffnungen versehen, so dass eine direkte Beaufschlagung der oberen Bereiche des Ladegutes bzw. der Paletten erfolgt.The air duct is such that for the upper air circuits, the air cooler are flowed vertically upwards, wherein the air is passed through a ceiling duct in the shaft. The bottom walls of this ceiling channel are provided with air outlet openings, so that a direct loading of the upper regions of the load or the pallets takes place.
Im unteren Luftkreislauf wird die Luft vertikal von oben nach unten ebenfalls über Ventilatoren durch die Luftkühler geführt, wobei die Luft durch einen Bodenkanal zum Schacht geführt wird. Auch hier ist die obere Wand des Bodenkanals mit Luftaustrittsöffnungen zur Versorgung der untersten Lage des Stapelgutes oder der Paletten mit frischgekühlter Luft versehen.In the lower air circuit, the air is vertically guided from top to bottom by fans through the air cooler, the air is guided through a bottom channel to the shaft. Again, the upper wall of the bottom channel is provided with air outlet openings for supplying the lowest layer of the stacked goods or pallets with freshly cooled air.
Zur Kühlung der Außenwände des Lagerraumes oder des Laderaumes sind die den Luftkühlern zugekehrten Luftkanäle der Luftkreisläufe so ausgebildet, dass ein Teil der Kaltluft zur Kühlung der Außenwände des Lagerraumes oder des Laderaumes abgezweigt wird.For cooling the outer walls of the storage space or the loading space, the air ducts facing the air coolers of the air circuits are designed so that a portion of the cold air is diverted to cool the outer walls of the storage room or the load compartment.
Hiernach ist bei dem erfindungsgemäßen Umluftsystem die Luftführung so gestaltet, dass für die oberen Kreise die Luftkühler vertikal nach oben durchströmt werden und die Luft über den Deckenkanal in den Stapelschacht geleitet wird. Im unteren Luftkreislauf wird die Luft vertikal von oben nach unten über die Ventilatoren durch die Luftkühler geführt und ebenfalls durch einen Kanal zum Stapelschacht geführt.After that, in the air circulation system according to the invention, the air duct is designed so that the air cooler are flowed vertically upwards for the upper circles and the air is passed through the ceiling duct in the stacking shaft. In the lower air circuit, the air is guided vertically from top to bottom over the fans through the air cooler and also led through a channel to the stacking shaft.
Mit einem derart erfindungsgemäß ausgebildeten Umluftsystem ist gewährleistet, dass das Hochregallager und auch der Lagerraum oder der Laderaum gleichmäßig und unter Aufrechterhaltung konstanter vorgegebener Temperaturen mit Kühlluft umspielt wird, so dass die Ladung in allen Lagen ausreichend gekühlt wird.With a circulating air system designed in accordance with the invention, it is ensured that the high-bay warehouse and also the storage space or the cargo space are uniformly and with cooling air played around while maintaining constant predetermined temperatures, so that the charge is sufficiently cooled in all positions.
Des weiteren umfasst die Erfindung einen ortsgebundenen Lagerraum oder einen Laderaum von Kühlschiffen mit mindestens einem Hochregallager, wobei der Lagerraum oder Laderaum mit einem Umluftsystem mit den Merkmalen der Ansprüche 1 bis 11 versehen ist.Furthermore, the invention comprises a stationary storage space or a cargo space of reefers with at least one high-bay warehouse, wherein the storage space or cargo space is provided with a recirculation system with the features of claims 1 to 11.
