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 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 .
  • 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.
  • 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.
  • 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.
  • 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 floor 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 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.
  • the wall 9 may be light or not insulated. In any case, however, the forced circulation and the thermosiphon effect should be effective.
