Abstract

Der Kühlgutbehälter setzt sich aus einem Kühlmittelteil (5) und einem Kühlgutteil (6) zusammen. Der Kühlmittelteil (5) zur Aufnahme von z.B. Trockeneis ist dicht verschlossen und gegen aussen stark isoliert. Es ist über eine Oeffnung (11) mit einem Leitungssystem (12) mit einem Eintritt in den Kühlguteil (6) verbunden, während der Kühlgutteil (6) eine Oeffnung (14) nach aussen aufweist. Im Kühlmittelbehälter (7) wird das Kühlmittel (8) durch Wärmeaufnahme verdampft; es entsteht ein Druckgefälle und damit ein Zwangsdurchlauf mit einer Zwangsumwälzung der verdampften Gasmassen im Kühlgutbehälter. Die Wand mit dem Leitungssystem (12) ist gegenüber der Türe (4) kälter, so dass durch diese Temperaturdifferenz eine Thermosiphonumwälzung entsteht, die die Zwangsumwälzung verstärkt. Da zudem die Wärme für das Verdampfen des Kühlmittels über die nicht oder schwach isolierte Trennwand (9) aus dem Kühlgutteil (6) entnommen wird, ist der thermische Wirkungsgrad des Kühlgutbehälters hoch und zudem wird durch die Zwangsumwälzung eine gleichmässige Kühlung des Kühlguts (15) erreicht.The refrigerated goods container consists of a coolant section (5) and a refrigerated goods section (6). The coolant part (5) for receiving e.g. Dry ice is tightly sealed and strongly insulated from the outside. It is connected via an opening (11) to a line system (12) with an entry into the refrigerated goods part (6), while the refrigerated goods part (6) has an opening (14) to the outside. In the coolant tank (7), the coolant (8) is evaporated by absorbing heat; there is a pressure drop and thus a forced flow with forced circulation of the vaporized gas masses in the refrigerated goods container. The wall with the line system (12) is colder than the door (4), so that this temperature difference creates a thermosiphon circulation, which reinforces the forced circulation. Since, in addition, the heat for the evaporation of the coolant is removed from the refrigerated goods part (6) via the non-insulated or weakly insulated partition (9), the thermal efficiency of the refrigerated goods container is high and, moreover, uniform cooling of the refrigerated goods (15) is achieved by the forced circulation .

Description

Die Erfindung betrifft ein Verfahren zum Kühlen eines Kühlgutes in einem Behälter mittels eines Kühlmittels, wobei der Innenraum des Behälters einen Kühlgutteil und einen Kühlmittelteil aufweist und einen Kühlgutbehälter zur Durchführung des Verfahrens.The invention relates to a method for cooling a product to be cooled in a container by means of a coolant, the interior of the container having a part to be cooled and a part of coolant and a container for cooling goods to carry out the method.

Kühlgutbehälter zur Aufnahme eines Kühlguts, die unabhängig von äussern Energiezuführungen arbeiten, sind in verschiedenen Ausführungen bekannt, vor allem als bewegliche und/oder fahrbare Behälter, wie sie vor allem im Transportsektor, z.B. bei der Eisenbahn und bei der Luftfahrt, in erheblichem Umfang eingesetzt werden. Mit solchen Kühlgutbehältern soll unter Verwendung eines geeigneten Kältemittels, z.B. Trockeneis (festes C02), das Kühlgut während einer bestimmten Zeitspanne unter der Umgebungstemperatur gehalten werden können. Solche Behälter werden auch als Mahlzeiten- und Lebensmittelbehälter eingesetzt, die zur Versorgung von Passagieren dienen. Hierbei wird gewöhnlich von der zuständigen Gesundheitsbehörde verlangt, dass die Mahlzeiten oder die Lebensmittel in einem bestimmten Temperaturbereich gehalten werden.Refrigerated goods containers for holding refrigerated goods, which work independently of external energy supplies, are known in various designs, above all as movable and / or mobile containers, as are used to a considerable extent primarily in the transport sector, for example in the railroad and in aviation . With such refrigerated goods containers, the refrigerated goods should be able to be kept below the ambient temperature for a certain period of time using a suitable refrigerant, for example dry ice (solid C0 2 ). Such containers are also used as meal and food containers, which serve to supply passengers. This usually requires the responsible health authority to keep meals or food within a certain temperature range.

Die Kühlwirkung solcher Kühlgutbehälter beruht darauf, dass das überwiegend als Kühlmittel verwendete Trockeneis unter Wärmezufuhr aus der Umgebung oder aus dem Kühlgutbehälter zum Verdampfen gebracht und dass dabei das entstehende kalte Gas, das schwerer als Luft ist, durch Schwerkraftwirkung ins Innere des Kühlgutbehälters geleitet wird. Damit können, solange der Trockeneisvorrat ausreicht, die Wärmeverluste durch die Wände des Kühlgutbehälters ganz oder wenigstens teilweise ausgeglichen werden.The cooling effect of such refrigerated goods containers is based on the fact that the dry ice, which is predominantly used as a coolant, is supplied with heat from the surroundings or from the cooling brought to evaporate the good container and that the resulting cold gas, which is heavier than air, is directed into the interior of the refrigerated goods container by the force of gravity. As long as the dry ice supply is sufficient, the heat losses through the walls of the refrigerated goods container can be fully or at least partially compensated for.

Bei einem bekannten Kühlgutbehälter ist der Innenraum in einen Kühlmittelteil für die Aufnahme des Kühlmittels und in einen Kühlgutteil für die Lagerung des Kühlgutes unterteilt, wobei sich der Kühlmittelteil unmittelbar unter dem Deckel bzw. der Decke des Behälters befindet. Da jedoch der Kühlmittelteil nur ungenügend gegen die Aussenumgebung isoliert ist, wird die Verdampfungswärme (Sublimationswärme) des Trockeneises zu einem wesentlichen Anteil der Umgebung entzogen und kommt so dem Kühlgut nicht mehr zugute. Da die Verdampfungswärme bei Trockeneis den weitaus grösseren Anteil an Kühlwirkung erbringen kann als die Erwärmung der dabei entstandenen kalten Kohlensäuregase, sind die Verluste bei den bekannten Kühlgutbehältern gross, und sie weisen demgemäss einen schlechtern thermischen Wirkungsgrad auf, abgesehen davon, dass auch keine gleichmässige Kühlwirkung im Kühlgutteil zustandekommt, und deshalb in der Nähe des Kühlmittelteils lagerndes Kühlgut stärker, sogar zu stark gekühlt werden kann.In a known refrigerated goods container, the interior is subdivided into a coolant part for receiving the coolant and into a refrigerated goods part for storing the refrigerated goods, the coolant part being located directly under the lid or the ceiling of the container. However, since the coolant part is insufficiently insulated from the outside environment, the heat of evaporation (sublimation heat) of the dry ice is largely removed from the environment and therefore no longer benefits the refrigerated goods. Since the heat of vaporization with dry ice can provide a far greater proportion of the cooling effect than the heating of the resulting cold carbon dioxide gases, the losses in the known refrigerated goods containers are large, and they accordingly have a poor thermal efficiency, apart from the fact that there is no uniform cooling effect in the Refrigerated goods part comes about, and therefore refrigerated goods stored near the coolant part can be cooled more strongly, even too strongly.

Hier setzt die Erfindung ein, der die Aufgabe zugrundeliegt, einen Kühlgutbehälter der eingangs beschriebenen Art so auszugestalten, dass eine Verbesserung seines thermischen Wirkungsgrads erreicht wird, wobei gleichzeitig eine Erhöhung der Umwälzgeschwindigkeit der kalten Gase im Kühlgutteil und ein kontrollierter Ablauf dieser Umwälzung erreicht wird.This is where the invention comes in, which is based on the object of designing a refrigerated goods container of the type described at the outset in such a way that an improvement of its thermal efficiency is achieved, at the same time an increase in the circulation rate of the cold gases in the refrigerated goods and a controlled sequence of this circulation is achieved.

Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass der Kühlmittelteil ein dicht abgeschlossener Raum ist, der über ein Leitungssystem mit dem Kühlgutteil verbunden ist, wobei der Kühlgutteil über eine Austrittsöffnung mit der Aussenumgebung verbunden ist. Durch die Serieschaltung Kühlmittelteil-Kühlgutteil-Aussenumgebung wird erreicht, dass ein Druckgefälle entsteht, so dass die entstehenden kalten Gase in der Art eines Zwangsumlaufs geführt werden.This object is achieved according to the invention in that the coolant part is a tightly sealed space which is connected to the refrigerated goods part via a line system, the refrigerated goods part being connected to the outside environment via an outlet opening. The series connection of the coolant part and the refrigerated goods outside environment ensures that a pressure drop arises, so that the resulting cold gases are conducted in the manner of a forced circulation.

Die Erfindung ist in der beiliegenden Zeichnung in einem Ausführungsbeispiel dargestellt und nachfolgend beschrieben. Die Figur zeigt einen Vertikalschnitt durch einen Kühlgutbehälter ohne äussere Energiezufuhr.The invention is shown in the accompanying drawing in one embodiment and described below. The figure shows a vertical section through a refrigerated goods container without external energy supply.

Der dargestellte Kühlbehälter weist isolierte Wände auf, von denen ein Boden 1, eine Rückwand 2 und eine Decke 3 dargestellt sind. Der Kühlgutbehälter ist durch eine ebenfalls wärmeisolierte Türe 4 geschlossen.The cooling container shown has insulated walls, of which a bottom 1, a rear wall 2 and a ceiling 3 are shown. The refrigerated goods container is closed by a heat-insulated door 4.

Der Innenraum des Kühlgutbehälters ist in einen Kühlmittelteil 5 und in einen wesentlich grösseren Kühlgutteil 6 unterteilt. Im Kühlmittelteil ist ein Behälter 7 zur Aufnahme eines Kühlmittels 8 eingeschoben, dessen Wände druckdicht abgeschlossen sind, wobei nur die gegen den Kühlgutteil 6 liegende Wandpartie 9 weniger stark wärmeisoliert ist. Die übrigen Wandteile des Kühlmittelbehälters 7 sind dagegen stark isoliert, um der Aussenumgebung keine Verdampfungswärme zu entziehen, was einer Verminderung des thermischen Wirkungsgrads des Kühlgutbehälters gleichkommen würde.The interior of the refrigerated goods container is subdivided into a coolant section 5 and a substantially larger refrigerated goods section 6. A container 7 for receiving a coolant 8 is inserted into the coolant part, the walls of which pressure-tight manner are completed, only the wall part lying against the K ühlgutteil 6 is less strongly heat-insulated. 9 The other wall parts of the coolant container 7, on the other hand, are strongly insulated so that no heat of vaporization is extracted from the outside environment, which would amount to a reduction in the thermal efficiency of the refrigerated goods container.

Damit eine wirklich zufriedenstellende Funktion eines solchen Kühlgutbehälters erreicht wird, ist eine gleichmässige Temperaturverteilung im Innern des Behälters wesentlich. Da die vorhandene Temperaturdifferenz zwischen dem Kohlensäuregas, dessen Sublimationstemperatur -78.5°C bei 760 Torr und dem Kühlgut mit einer Temperatur von 6 - 18°C für Lebensmittel und Mahlzeiten beträchtlich ist, ist eine Umwälzung und Durchmischung der Gasmassen im Innern des Kühlgutteils 6 anzustreben. Dies wird durch die nachstehend geschilderten Massnahmen erreicht.In order to achieve a really satisfactory function of such a refrigerated goods container, a uniform temperature distribution inside the container is essential. Since the existing temperature difference between the carbonic acid gas, its sublimation temperature -78.5 ° C at 760 Torr and the refrigerated goods with a temperature of 6 - 18 ° C for food and meals is considerable, circulation and mixing of the gas masses inside the refrigerated goods section 6 should be aimed for. This is achieved through the measures described below.

Im Kühlmittelbehälter 7 ist an der Rückwand 2 mindestens eine Oeffnung 10 angeordnet, die durch eine Weichdichtung 11 an der Rückwand 2 druckdicht abgedichtet ist und eine Verbindung zu einem Druckleitungssystem 12 freigibt, das in der Rückwand 2 des Kühlgutbehälters integriert ist. Durch mindestens eine Oeffnung 13 wird eine Verbindung zum Kühlgutteil 6 geschaffen, die beispielsweise in der Nähe des Bodens 1 liegt. Ueber der Türe 4 wird mindestens eine weitere Oeffnung 14 vorgesehen.In the coolant container 7, at least one opening 10 is arranged on the rear wall 2, which is sealed pressure-tight by a soft seal 11 on the rear wall 2 and releases a connection to a pressure line system 12 which is integrated in the rear wall 2 of the refrigerated goods container. Through at least one opening 13, a connection to the refrigerated goods part 6 is created, which lies for example in the vicinity of the bottom 1. At least one further opening 14 is provided above the door 4.

Dadurch, dass dem Kühlmittel, z.B. Trockeneis, in dem druckdicht verschlossenen Kühlmittelbehälter 7 Wärme zugeführt wird, entsteht beim Verdampfen im Innern des Behäl- ters 7 ein Ueberdruck, der dazu verwendet wird, um eine Zwangsumwälzung im Innern des Kühlgutteils in Gang zu setzen. Dies wird erreicht durch das Druckleitungssystem 12 mit den Oeffnungen 13, 14 zum Kühlgutteil 6 und zur Aussenumgebung. Es entsteht ein Druckgefälle, das zu einem Zwangsdurchlauf mit einer Zwangsumwälzung des Kühlmittels im Kühlgutteil führt. Die Umwälzung der Gasmassen wird dadurch verbessert, dass die Oeffnungen 13, 14 an entgegengesetzten Wänden und zudem diametral versetzt angeordnet sind.The fact that the coolant, such as dry ice, in the pressure-sealed coolant tank 7 is supplied heat generated during the evaporation inside the B ehäl- ters 7 an excess pressure, which is used to implement a forced circulation inside the Kühlgutteils going. This is achieved by the pressure line system 12 with the openings 13, 14 to the refrigerated goods part 6 and to the outside environment. A pressure drop arises, which leads to a forced flow with forced circulation of the coolant in the refrigerated goods part. The circulation of the gas masses is improved in that the openings 13, 14 are arranged on opposite walls and also diametrically offset.

Da zudem die Rückwand 2 mit dem Leitungssystem 12 kälter ist als die weniger isolierte Wand der Türe 4, wird die erwähnte Zwangsumwälzung durch eine Schwerkraftumwälzung infolge einer Thermosiphonwirkung verstärkt. Selbstverständlich können die "kalte" und "warme" Wand anders angeordnet sein als in dem in der Figur dargestellten Beispiel.Moreover, since the rear wall 2 to the conduit system 12 is colder than the less insulated wall of the door 4, the above-mentioned Z is amplified by a gravity circulation due to a thermo-siphon circulation Wang. Of course, the "cold" and "warm" wall can be arranged differently than in the example shown in the figure.

Durch die beschriebene Ausbildung des Kühlgutbehälters wird demnach erreicht, dass die durch die Kühlmittel-Sublimation entstehenden Gasmassen in einem Zwangsdurchlauf mit Zwangsumwälzung durch den Kühlgutteil 6 fliessen, dass weiter durch die Anordnung "kalter" und "warmer" Wände diese Zwangsumwälzung durch Thermosiphonwirkung verstärkt und dass die Wärme für die Verdampfung des Kühlmittels 8 dem Kühlgutteil 6 entnommen wird. Daraus resultiert ein Kühlgutbehälter, bei dem eine gleichmässige Kühlung des z.B. in Portionen 15 im Kühlgutteil 6 gelagerten Kühlguts gewährleistet ist und der einen hohen thermischen Wirkungsgrad aufweist. Sollte an einzelnen Stellen des Kühlgutteils 6 die Kühlwirkung zu intensiv sein, kann dem durch eine Abschirmung 16,z.B. durch Platten oder Folien, im Bereich des Kühlmittelbehälters 7 oder der Oeffnung 13 leicht abgeholfen werden.The described design of the refrigerated goods container thus achieves that the gas masses produced by the coolant sublimation flow in a forced pass with forced circulation through the refrigerated goods part 6, that this forced circulation is further reinforced by the arrangement of "cold" and "warm" walls by thermosiphon action and that the heat for the evaporation of the coolant 8 is taken from the refrigerated goods part 6. From that The result is a refrigerated goods container in which uniform cooling of the refrigerated goods stored in portions 15 in the refrigerated goods part 6 is ensured and which has a high thermal efficiency. If the cooling effect is too intense at individual points of the refrigerated goods part 6, this can easily be remedied by a shield 16, for example by plates or foils, in the area of the coolant container 7 or the opening 13.

Der beschriebene Kühlgutbehälter kann auch etwas variiert werden. Das Druckleitungssystem 12 kann anstatt nur in einer Wand in zwei oder in mehreren Wänden eingebaut sein. Es können auch zwei oder mehr Oeffnungen 13, 14 vorgesehen werden, die zudem an anderen Stellen angeordnet werden können. Dementsprechend kann auch die Anordnung der "warmen" oder "kalten" Wand verschieden sein. Die Wand 9 kann leicht oder nicht isoliert sein. In jedem Fall soll jedoch die Zwangsumwälzung und die Thermosiphonwirkung wirksam sein.The refrigerated goods container described can also be varied somewhat. The pressure line system 12 can be installed in two or more walls instead of only in one wall. Two or more openings 13, 14 can also be provided, which can also be arranged at other locations. Accordingly, the arrangement of the "warm" or "cold" wall can be different. The wall 9 may be light or not insulated. In any case, however, the forced circulation and the thermosiphon effect should be effective.
