Definitions

  • the present invention relates to conservation, in isothermal conditions independent of any external energy source, of all products such as for example foods or products pharmaceuticals for which a uniform temperature must be preserved between the time of their preparation and use by a user final.
  • Each compartment must provide a temperature constant ambience both in the volume of said compartment and in the necessary autonomy time to keep these speakers out of any source external refrigerant energy, and in any condition causes at least for a period between 0 and 4 hours.
  • temperature constant or a temperature atmosphere for which the variations are within plus or minus 4 ° C around the temperature selected in the product compartment cool and the temperature variation is between -18 ° C and -26 ° C in the product compartment frozen; the meaning of maintaining a constant or almost constant temperature notwithstanding variations in the outside temperature also applies to variations over time in an interval of 0 to 4 h during which the enclosure is dissociated from any external cold source.
  • the object of the present invention is also to produce such an insulated enclosure comprising a any number of compartments that can be individually kept at different temperatures, not requiring implementation, in this enclosure, separating partitions made of insulating material inert, which would create a large dead volume at inside the enclosure.
  • the invention which consists, in accordance with the preamble of claim 1 or 2, in the development of a double-sided partition element, removable, usable in particular in an isothermal enclosure, comprising a first compartment, not waterproof, filled with an element solid and sublimable refrigerant, for example dry ice, and provided with openings distributed in such a way substantially homogeneous on its external face.
  • the invention is characterized in that the partition element has in its thickness a second compartment adjoining the first, this second watertight compartment, can be assimilated to a box, and being filled by a eutectic melting temperature significantly higher than the sublimation or melting temperature of the refrigerant, in the form of gel or mixture, or by the air.
  • the partition element has the function of directing and maintain temperatures sufficiently different to be able to provide compartments suitable for simultaneously containing frozen products in one and fresh produce in the other, without break in the cold chain for all products considered.
  • eutectic in the present requires any mixture of two or more bodies whose fusion takes place at constant temperature. In these conditions, as long as the frigories are brought by dry ice, eutectic stays at a temperature constant which is its melting temperature which can therefore be determined by the choice of mixture eutectic considered, depending on the temperature atmosphere chosen in the compartment.
  • the only condition is that the temperature of solidification of the refrigerant (dry ice) or very significantly below the melting temperature gel or eutectic mixture.
  • this agent refrigerant will consist of solid carbon dioxide in all its forms (wafers, sticks, pellets, snow) whose sublimation temperature is -78 ° C at atmospheric pressure, but we can consider other refrigerants, in other applications.
  • this refrigerant may have the function of directing a temperature, even very low, in one of the volumes of the enclosure isothermal and transfer the frigories necessary to through the buffer housing described above with a view to maintain another different directed temperature in another volume of the insulated enclosure, temperature determined according to the intended application, this temperature being for example close to 0 ° C for keeping food fresh.
  • a partition element conforming to the invention may thus constitute in an enclosure isothermal at least two temperature compartments different: on the side of the refrigerant space, a temperature freezer compartment principle significantly below 0 ° C (up to -18 or -25 ° C if applicable) for products to be kept at negative temperatures and on the side of the buffer housing containing for example the eutectic gel, a refrigeration compartment at temperature close to 0 ° C for products to keep fresh.
  • the "buffer box” so represents between these two fridge and freezer compartments, one "impedance balance" mechanism avoiding recourse to any inert insulating partition.
  • temperatures in the different compartments can be adjusted and held in the time at the desired values as a function of the impedance of the buffer and that of the refrigerant, as well as heat losses to the outside (depending on the outside temperature), from the initial state of the buffer (eutectic) and the expected duration of transport.
  • a gap is formed between said housing and the lower part of said wall not waterproof or grid to allow the flow of said refrigerant gas down, this being heavier that air in case it comes from sublimation solid carbon dioxide (CO2).
  • CO2 sublimation solid carbon dioxide
  • the element can also be characterized in that the lower part of said housing is widened at its base to provide said buffer with a volume of capacity sufficient, this housing being advantageously made of a material with high thermal conductivity, for example in stainless steel or aluminum.
  • the refrigerant agent can come under any appropriate form recalled previously and the users will thus be able to obtain easily and low price the refrigerant, and introduce it into said element space just before placement of these in the isothermal enclosure.
  • the invention further relates to an enclosure isothermal fitted with one or more partition elements as just defined (see claims 8 to 13).
  • Such an enclosure preferably have the shape of a box or a classic parallelepiped box with insulating walls, can be closed hermetically using a also insulating cover, partition elements being then established, in this enclosure, as removable vertical walls, allowing to create compartments in this enclosure modular that can be maintained at different temperatures.
  • the height of the box or box representing the isothermal enclosure is substantially equal to the height of the double-sided partition element of the invention.
  • Such an enclosure could thus contain at least one element double-sided removable partition, comprising in its thickness two compartments contiguous to each other, the first compartment, not waterproof, being susceptible to be filled with a solid refrigerant and sublimable, in particular carbon dioxide or dry ice, the second compartment, waterproof, or case, being filled with a eutectic type buffer substance; a such a double-sided partition element delimits two compartments in the enclosure; it goes without saying that two partition elements determine three enclosures, etc ...
  • the insulated enclosure compartment adjoining the waterproof housing part of the double partition element face maintains the ambient temperature of said compartment at a temperature close to eutectic melting temperature, while the compartment adjoining the non-waterproof part of the double-sided partition element containing an element refrigerant is maintained at room temperature less than or equal to -18 ° C, therefore much less than the former.
  • the insulated enclosure provided with partition elements to removable double sided of the invention be loaded either with frozen products that already have a temperature less than or equal to -18 ° C for the compartment freezer next to the compartment containing the refrigerant, and products previously brought to the desired temperature for the product compartment fresh.
  • an entire refrigeration enclosure temperature generally positive
  • an entire enclosure of freezing negative temperature
  • such an enclosure has grooves extending at its bottom perpendicular to the plane of the cooling elements, these grooves allowing the circulation of gas from sublimation of the refrigerant, this gas, in principle refrigerated CO2 from gas sublimation solid carbon dioxide constituting the refrigerant, being heavier than air.
  • the whole device comprising an enclosure isothermal fitted with one or more partition elements removable double sided as described above therefore allows a double temperature transfer directed with maintaining a temperature which is: a) in the fresh produce compartment with an ambient temperature of 4 ° C ⁇ 4 ° C, said fresh product contained in such a compartment keeping a core temperature of 2 ° C ⁇ 2 ° C for a period between 0 and 4 hours, it being understood that the enclosure fitted with the double-sided partition the invention being charged with a fresh product previously brought to a homogeneous temperature of 2 ° C; b) with regard to the frozen food compartment, room temperature is maintained at a temperature less than or equal to -18 ° C, knowing that the the invention allows natural convection allowing the maintenance of a temperature not presenting no difference greater than 6 ° C between the top and the bottom of the enclosure; the core temperature of the products previously frozen and arranged in such compartment varies within a maximum range of -26 ° C at -18 ° C.
  • grooves extending perpendicular to the plane of the partition elements described above allows the circulation of gas from sublimation of the refrigerant by ensuring the natural convection of temperature and allowing maintaining homogeneous ambient temperature throughout the compartment within the limits described above.
  • the isothermal enclosure partially shown in perspective was referenced in 1 and is in the form of a box with lateral insulating walls 2 and ends 3, developed for example by molding of synthetic material, and comprising a foam of insulating material 4 between two shells, exterior 5 and interior 6; she can be closed with a waterproof cover (fig. 3).
  • the shell 6 On its lateral faces, the shell 6 has pairs of opposite vertical grooves 7, spaced according to a specific module.
  • the bottom 8 of the box and the extreme walls 3 they have ribs longitudinal 9.
  • the double-sided partition element having a double thermal transfer function, realized by example in stainless steel, is globally referenced in 10. It includes a buffer housing consisting of a flat (or ribbed) part 11 widened at its base at 12 and constituting a reservoir for a eutectic gel, water, air, expanded insulating material, etc.
  • the element 10 has a profile 13 allowing element 10 to be guided vertically by the grooves side 7 of the enclosure 1 during its installation in the latter.
  • Element 10 further includes a free space contiguous to face 11, extending above of the widened part 12 and delimited by a sheet metal perforated, grid or the like, referenced 14 in parallel to the flat part 11.
  • the fixing of the grid 14 on the buffer tank is provided by all suitable means, for example welding spots 17 between the grid and the corresponding part of the buffer tank.
  • this free space can be filled with a refrigerant 15 for example solid carbon dioxide, in all its forms.
  • the gas carbonic sublimation can escape in the insulated enclosure 1, on the side opposite the part plate 11, crossing the grid 14.
  • a temperature freezing for example of the order of -25 ° C (negative temperature)
  • Figure 4 there is shown an arrangement to obtain a refrigeration temperature, for example of the order of + 3 ° C, overall the isothermal enclosure 1. All you need is to have elements 10, with the desired agent charge refrigerant 15 so that their smooth faces 10 are arranged opposite each other, the grids 14 of these elements then being applied against the extreme walls 3 of the enclosure.
  • the layout reverse of the elements 10 will get in any the enclosure a freezing temperature for example of the order of -25 ° C.
  • FIG. 6 Another mode of implementation is shown in Figure 6 and relates to an insulated cabinet in the form of a refrigeration cabinet.
  • One of the elements 10 ' will always be arranged at the party the other element 10 ′ can be arranged at different heights, resting on cleats in projection 20 or of configuration similar to the example previous (groove 7 and conjugate profile 13), provided on the side walls 21 of the cabinet, or be of design similar to the cooling element and freezer described above.
  • the cooling element and freezer 10 'can consist of a tank 22 for the eutectic gel or the buffer tank, and of a tank 23 in thermal contact with this tank and intended to contain the refrigerant 24, again consisting, for example, of solid carbon dioxide.
  • the tray 23 being closed by a grid 14 ', we can have food or other products to maintain frozen, for example at a temperature of the order of -25 ° C as in the previous application, while that the lower part of the enclosure could be maintained at a refrigeration temperature of the order, for example, of 3 ° C for the products to keep it cool, and this for the duration of the transport of the cabinet 1 '.
