- 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.
- 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 evaporated when heat is supplied from the surroundings or from the refrigerated goods container, and that cold gas that is produced, which is heavier than air, is conducted into the interior of the refrigerated goods container by gravity.

- the heat of vaporization in 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 poorer thermal efficiency, apart from the fact that there is no uniform cooling effect in the Refrigerated goods part comes about and therefore in the vicinity of the coolant part stored refrigerated goods can be cooled more strongly, even too strongly.

- 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.
- a connection to the refrigerated goods part 6 is created through at least one opening 13, which lies, for example, in the vicinity of the base 1.
- At least one further opening 14 is provided above the door 4.
- the described design of the refrigerated goods container therefore achieves that the gas masses created by the coolant sublimation flow in a forced pass with forced circulation through the refrigerated goods part 6, that the arrangement of " cold” and “ warm” walls further increases this forced circulation by thermosiphon effect and that the heat for the Evaporation of the coolant 8 is removed from the refrigerated goods part 6.
- 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.

Description
Die Erfindung betrifft einen Kühlgutbehälter zum Kühlen eines Kühlgutes in einem Behälter mittels eines durch Wärmezufuhr verdampfbaren Kühlmittels, wobei der Innenraum des Behälters einen Kühlgutteil mit wärmeisolierten Wänden und einen das Kühlmittel aufnehmenden Kühlmittelteil aufweist, welche über ein Druckleitungssystem miteinander verbunden sind, dessen Eintritt in den Kühlgutteil entfernt von einer mit der Aussenumgebung in Verbindung stehenden Austrittsöffnung angeordnet ist. Kühlgutbehälter zur Aufnahme eines Kühlgutes, die unabhängig von äusseren 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 Kühlmittels, 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.The invention relates to a refrigerated goods container for cooling a refrigerated goods in a container by means of a coolant that can be evaporated by the supply of heat, the interior of the container having a refrigerated goods part with heat-insulated walls and a coolant part receiving the coolant, which are connected to one another via a pressure line system, the entry thereof into the refrigerated goods part is arranged away from an outlet opening which is connected to the outside environment. Refrigerated goods containers for receiving refrigerated goods, which work independently of external energy supplies, are known in various designs, especially as movable and / or mobile containers, as are primarily used in the transport sector, e.g. B. in railways and aviation, are used to a significant extent. With such refrigerated goods containers using a suitable coolant, for. B. dry ice (solid C0 2 ), the refrigerated goods can be kept below the ambient temperature for a certain period of time. 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 entstehende kalte Gas, das schwerer als Luft ist, durch Schwerkraftwirkung ins Innere des Kühlgutbehälters geleitetwird. 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 evaporated when heat is supplied from the surroundings or from the refrigerated goods container, and that cold gas that is produced, which is heavier than air, is conducted into the interior of the refrigerated goods container by 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.
Die FR-A Nr. 2188122 zeigt einen Kühlgutbehälter, bei dem der Innenraum in einen Kühlmittelteil für die Aufnahme des Kühlmittels und in einen Kühlgutteil für die Lagerung des Kühlgutes unterteilt ist, wobei sich der Kühlmittelteil unmittelbar unter der Decke des Behälters befindet. Das aus dem Kühlmittel entstehende kalte Gas wird in einem Kanal an einer Seitenwand des Behälters nach unten zu dem Kühlgutteil geleitet und gelangt in diesen über Führungsklappen. Der Kühlgutteil steht über Öffnungen mit derAussenumgebung in Verbindung.FR-A No. 2188122 shows a refrigerated goods container in which the interior is subdivided into a coolant part for receiving the coolant and a refrigerated goods part for storing the refrigerated goods, the coolant part being located directly under the ceiling of the container. The cold gas resulting from the coolant is guided downward in a channel on a side wall of the container to the part to be refrigerated and reaches it via guide flaps. The refrigerated goods section communicates with the outside environment via openings.
Der Kühlmittelteil selbst ist zwar sowohl gegenüber der Decke des Behälters als auch gegenüber dem Kühlgutteil isoliert, ansonsten weist der Behälter keine weitere Wärmeisolation auf, so dass die Verdampfungswärme (Sublimationswärme) des Kühlmittels zu einem wesentlichen Anteil der Umgebung entzogen wird und nicht mehr dem Kühlgutzugute kommt. 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 schlechteren thermischen Wirkungsgrad auf, abgesehen davon, dass auch keine gleichmässige Kühlwirkung im Kühlgutteil zustande kommt und deshalb in der Nähe des Kühlmittelteils lagerndes Kühlgut stärker, sogar zu stark gekühlt werden kann. Ebenso verringert eine Isolation von Kühlmittelteil zu Kühlgutteil die Kühlwirkung.The coolant part itself is insulated both from the top of the container and from the refrigerated goods part, otherwise the container has no further heat insulation, so that the heat of vaporization (sublimation heat) of the coolant is extracted to a significant extent from the environment and no longer benefits the goods to be refrigerated . Since the heat of vaporization in 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 poorer thermal efficiency, apart from the fact that there is no uniform cooling effect in the Refrigerated goods part comes about and therefore in the vicinity of the coolant part stored refrigerated goods can be cooled more strongly, even too strongly. Insulation from the coolant part to the refrigerated goods part also reduces the cooling effect.
Aus der US-A Nr. 1880735 ist ein Kühlgutbehälter mit getrenntem Kühlmittel- und Kühlgutteil bekannt, bei welchem das kühlende Gas um den Kühlgutteil herumgeleitet wird und gegenüber dem Kühlmittelteil in den Kühlgutteil eintritt. Durch Öffnungen wird das Gas sowohl wiederzurück in den Kühlmittelteil geführt, kann jedoch durch andere Öffnungen auch nach aussen entweichen.From US-A No. 1880735 a refrigerated goods container with a separate coolant and refrigerated goods part is known, in which the cooling gas is passed around the refrigerated goods part and enters the refrigerated goods part opposite the coolant part. The gas is both led back into the coolant part through openings, but can also escape to the outside through other openings.
Ähnliches zeigt auch die US-A Nr. 2263522. Beide Kühlbehälter haben den Nachteil, dass sie im wesentlichen gleichmässig isolierte Wände aufweisen, so dass die Umwälzung des Kühlgases allein von seiner Schwerkraft und dem Zusammenspiel mit den Aussenöffnungen abhängt. Zum anderen kommt es durch das direkte Einbringen des Kühlmittels in den Kühlmittelteil beim Verbrauch des Kühlmittels zu Verunreinigungen, welche nur umständlich beseitigt werden können. Hier setzt die Erfindung ein, der die Aufgabe zugrunde liegt, einen Kühlgutbehälter der eingangs beschriebenen Art so auszugestalten, dass eine Verbesserung seines thermischen Wirkungsgrades erreicht wird, wobei gleichzeitig eine Erhöhung der Umwälzgeschwindigkeit der kalten Gase im Kühlgutteil und ein kontrollierter Ablauf dieser Umwälzung erreicht werden.The US-A No. 2263522 shows something similar. Both cooling containers have the disadvantage that they have essentially uniformly insulated walls, so that the circulation of the cooling gas depends solely on its gravity and the interaction with the outer openings. On the other hand, the direct introduction of the coolant into the coolant part leads to contamination when the coolant is consumed, which can only be removed with great difficulty. 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 in its thermal efficiency is achieved, at the same time increasing the circulation speed of the cold gases in the refrigerated goods part and a controlled course of this circulation.
Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass der Kühlmittelteil ein dichtabgeschlossener Druckraum ist, welcher über das Druckleitungssystem mit dem unteren Bereich des Kühlgutteils in Verbindung steht und welcherstark wärmeisolierende Wandteile und gegen den Kühlgutteil nicht oder nur schwach wärmeisolierende Wandteile aufweist, und dass die im Abstand zueinander angeordneten Wände des Kühlgutteils zur Erzielung bzw. Unterstützung einer Thermosiphonwirkung unterschiedlich wärmeisoliert sind, wobei die Wand, in welcher die Austrittsöffnung in deren oberen Bereich angeordnet ist, schwächer isoliert ist als die ihr gegenüberliegende Wand.This object is achieved according to the invention in that the coolant part is a tightly sealed pressure chamber, which is connected via the pressure line system to the lower region of the refrigerated goods part and which has highly heat-insulating wall parts and not or only weakly heat-insulating wall parts against the refrigerated goods part, and in that Walls of the refrigerated goods part which are arranged at a distance from one another are insulated to different degrees in order to achieve or support a thermosiphon effect, the wall in which the outlet opening is arranged in its upper region being less insulated than the wall opposite it.
Durch die Serieschaltung Kühlmittelteil-Kühlgutteil-Aussenumgebung wird einmal erreicht, dass ein Druckgefälle entsteht, so dass die entstehenden kalten Gase in der Art eines Zwangsumlaufs geführt werden. Die Durchmischung wird weiter durch das unterschiedliche Temperaturgefällezwischen den unterschiedlich isolierten Wänden verstärkt.The series connection of the coolant part and the refrigerated goods part of the outside environment ensures that a pressure drop occurs, so that the resulting cold gases are conducted in the manner of a forced circulation. Mixing is further enhanced by the difference in temperature between the differently insulated walls.
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.The cooling container shown has insulated Walls, of which a floor 1, a rear wall 2 and a ceiling 3 are shown.
Der Kühlbehälter ist in einen Kühlmittelteil 5 und in einen wesentlich grösseren Kühlgutteil 6 unterteilt. Der Kühlgutbehälter ist durch eine ebenfalls wärmeisolierte Tür 4 geschlossen. 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 cooling container is subdivided into a
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 bis 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 to 18 ° C for food and meals is considerable, there is a circulation and mixing of the gas masses inside the refrigerated goods part 6 to strive for. This is achieved through the measures described below.
Im Kühlmittelbehälter 7 ist an der Rückwand 2 mindestens eine Öffnung 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 Öffnung 13 wird eine Verbindung zum Kühlgutteil 6 geschaffen, die beispielsweise in der Nähe des Bodens 1 liegt. Über der Tür 4 wird mindestens eine weitere Öffnung 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
Dadurch, dass dem Kühlmittel, z. B. Trockeneis, in dem druckdicht verschlossenen Kühlmittelbehälter 7 Wärme zugeführt wird, entsteht beim Verdampfen im Innern des Behälters 7 ein Überdruck, der dazu verwendet wird, um eine Zwangsumwälzung im Innern des Kühlgutteils in Gang zu setzen. Dies wird erreicht durch das Druckleitungssystem 12 mit den Öffnungen 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 Öffnungen 13, 14 an entgegengesetzten Wänden und zudem diametral versetzt angeordnet sind.The fact that the coolant, for. B. dry ice, in the pressure-tightly sealed coolant container 7, heat is generated during evaporation inside the container 7, an excess pressure which is used to set a forced circulation in the interior of the refrigerated item in motion. This is achieved by the
Da zudem die Rückwand 2 mit dem Leitungssystem 12 kälter ist als die weniger isolierte Wand der Tür 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.In addition, since the rear wall 2 with the
Durch die beschriebene Ausbildung des Kühlgutbehälters wird demnach erreicht, dass die durch die Kühlmittelsublimation entstehenden Gasmassen in einem Zwangsdurchlauf mit Zwangsumwälzung durch den Kühlgutteil 6 fliessen, dassweiterdurch 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 Öffnung 13 leicht abgeholfen werden.The described design of the refrigerated goods container therefore achieves that the gas masses created by the coolant sublimation flow in a forced pass with forced circulation through the refrigerated goods part 6, that the arrangement of " cold" and " warm" walls further increases this forced circulation by thermosiphon effect and that the heat for the Evaporation of the coolant 8 is removed from the refrigerated goods part 6. This results in a refrigerated goods container in which a uniform cooling of the z. B. is guaranteed in portions 15 in the refrigerated goods 6 refrigerated goods and has a high thermal efficiency. Should the cooling effect be too intense at individual points of the refrigerated goods part 6, this can be prevented by a
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 Öffnungen 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
