Definitions

  • 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.
  • 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 .
  • 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 ).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 refrigerated goods container is closed by a heat-insulated door 4.
  • 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 yergutteil 6 is less strongly heat-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, which lies for example in the vicinity of the bottom 1.
  • At least one further opening 14 is provided above the door 4.
  • the coolant such as dry ice
  • the pressure-sealed coolant tank 7 is supplied heat generated during the evaporation inside the B enosl- ters 7 an excess pressure, which is used to implement a forced circulation inside thedegutteils 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.
  • 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.
  • 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.
