Definitions

  • 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 supplying heat, the interior of the container being divided by means of a wall into a refrigerated goods part with heat-insulating walls and into a coolant part receiving the coolant, which are connected to one another via a pressure line system , whose entry into the refrigerated goods section is located away from an outlet opening that connects the refrigerated goods section with the outside environment
  • refrigerated goods containers for receiving refrigerated goods that work independently of external energy supplies are known in various designs, especially as movable and / or mobile containers, such as they are used to a considerable extent, above all in the transport sector, for example in the railroad and in aviation.
  • Such refrigerated goods containers should be able to keep the refrigerated goods below the ambient temperature for a certain period of time using a suitable coolant, for example dry ice (solid CO 2 ).
  • a suitable coolant for example dry ice (solid CO 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.
  • 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 while supplying heat from the environment or from the refrigerated goods container, and the resulting cold gas, which is heavier than air, is directed 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.
  • a cooling device with a refrigerated goods part which is cooled by a gaseous coolant which emerges from a replaceable container at a high outlet speed and is then slowed down.
  • the coolant heated after flowing through the item to be refrigerated is passed back to the container so that sufficient cooling of the item to be cooled is achieved by evaporation of the coolant in the container.
  • FR-A No. 2188122 shows a refrigerated goods container in which 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 ceiling of the container.
  • the cold gas resulting from the coolant is guided downwards 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.
  • the coolant part itself is insulated from both the top of the container and the refrigerated 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 comes to the goods to be refrigerated .
  • 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. Isolation from the coolant part to the refrigerated goods part also reduces the cooling effect.
  • the coolant part is a tightly sealed pressure chamber which is connected exclusively to the lower region of the refrigerated goods part via the pressure line system and which has strongly insulating wall parts and wall parts which are not or only slightly insulated against the refrigerated goods part, and in that the spaced-apart walls of the item to be refrigerated are differently insulated 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.
  • 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.
  • the cooling container shown has insulated walls, of which a bottom 1, a rear wall 2 and a ceiling 3 are shown.
  • the cooling container is subdivided into a coolant part 5 and a substantially larger refrigerated goods part 6.
  • the refrigerated goods container is closed by a door 4 which is also thermally insulated.
  • a container 7 for receiving a coolant 8 is inserted in the coolant part, the walls of which are closed in a pressure-tight manner, only the wall part 9 lying against the refrigerated goods part 6 being less thermally insulated.
  • 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.
  • At least one opening 10 is arranged on the rear wall 2, which is sealed in a pressure-tight manner 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 coolant e.g. Dry ice
  • the coolant container 7 which is closed in a pressure-tight manner
  • the circulation of the gas masses is improved in that the openings 13, 14 are arranged on opposite walls and also diametrically offset.
  • the described design of the refrigerated goods container therefore ensures that the gas masses created 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 is removed from the refrigerated goods part 6 for the evaporation of the coolant 8.
  • the refrigerated goods container described can also be slightly varied.
  • the pressure inclination 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.
