It comprises an enclosure defined by a double layer that encloses a compressed fiberglass substrate that allows easy and effective isolation of a large equipment with a system of flexibility and improved integrity.
  • This insulation panel consists of a vacuum welded film wrapping, composed of two sheets of double layers of film, each having a plastic layer (tetraphthalate polyester (Mylar MR) polyethetrafluoroethylene (Teflon MR), polyamide (Kapton MR), fluorinated propylene ethylene, poly (vinylidene chloride) (Sarán MR), and polyethylene) and one made of metal (aluminum, silver, gold, chromium, nickel, stainless steel and Inconel (MR)).

  • E90312714 (22.1 1.1990) discloses a VACUUM INSULATION SYSTEM TO INSULATE REFRIGERATING FURNITURE, which refers to a domestic refrigeration apparatus and, more particularly, to a vacuum insulation panel system for its use in such devices. It provides an insulating system for a refrigeration apparatus, in which the vacuum panels are used in conjunction with polyurethane foam insulation in order to maximize thermal efficiency and structural rigidity of the chamber. Vacuum insulation panels will provide excellent thermal resistance by themselves. However, the design of current refrigeration chamber chambers excludes the use of vacuum insulating panels alone. The polyurethane foam insulation used in today's refrigeration devices acts as a structural member of the chamber, while providing a good means of thermal insulation. Therefore, this invention uses a combination of relatively thin vacuum insulating panels with polyurethane foam.
  • vacuum insulation panels whose support materials are suitable for themselves, to withstand without damage the heat that emerges in the exothermic reaction of the process of foaming, but now they can also be considered for material support bodies that could suffer damage due to the heat given off in the foaming process, but taking into account their own weight, cost and also their low thermal conductivity offer clear advantages with with respect to those mentioned in the first place and which, therefore, are especially suitable for the large-scale production of housings of domestic refrigerating appliances.
  • vacuum insulation panels can now be used with support bodies of open cell organic polymer foams, in particular polystyrene foams.

  • Each panel comprises two enveloping sheets, an inner sheet and another outer sheet formed from a SIO2-PMMA resin matrix reinforced with natural cellulose nanofibers, and a 1 hPa intermediate vacuum chamber, disposed between the inner sheet and the outer sheet, filled with a monolithic silica airgel.
  • the joining means between panels have a recess in two of the first contiguous edges of the panel in a first corner of the panel and a stepping of the same thickness as the recess in the two contiguous edges in the second corner opposed to the first corner.
  • a barrier envelope film is glued on all or part of the inner face of each of the two rigid walls, the dimensions of which are greater than those of the walls, so that a controlled level of adhesion of the films is obtained,
  • the assembly formed by the open barrier envelope containing the core and the two walls is placed in a vacuum chamber so that a controlled vacuum is created within the open barrier envelope
  • the barrier envelope is sealed throughout its periphery so that the soul is imprisoned there under vacuum
  • the first problem is that the panels, when generating the vacuum inside, suffer from an overpressure, equivalent to the atmospheric pressure, that crushes them; the solution has been, to place in the soul of the panel, a very porous material and with a very low heat transmissivity, for example gel aerospace, cellular glasses, all of them very expensive materials.
  • the second problem is the thermal bridges that are generated between panel and panel, and the possible air currents between the joints, in addition to the impossibility of cutting as they lose the vacuum;
  • the solution has been to create panels of various measures that, by combining them, give the exact measurement of the wall, being another option the custom construction.
  • the boards are treated with special tapes, which makes the work more expensive and lengthens the execution times.
  • the third problem is the reliability of the vacuum, which is marked by the resistance of the materials to the degradation in time and the possible aggressions that they could suffer, in addition to the recombination of elements that can reduce the vacuum;
  • This has been solved by attaching the panel itself to other insulators, which protect its perimeter, and that in case of loss of vacuum, they would partially replace the insulating characteristics, but this increases and increases the thicknesses, which was one of the advantages of panel.

  • the paneling of the invention solves the problems posed by other isolates of this type already known in the market, mentioned above in the background section, since the air chamber necessary to create the vacuum may have, depending on the modality desired, a core of alveolar polycarbonate, reticular polyethylene and / or cardboard, corrugated or hexagonal, which are much cheaper materials than those used by existing systems and that more than meet the requirements of compressive strength, and have low transmissibility of heat, in addition, they are mostly recyclable or can be obtained from recycling.
