  • Publication number: 20150300752
    Abstract: A process is for the pre-conditioning of one or more latent heat storage elements in the case of which the temperature or the narrow temperature range of the phase transition defines a target temperature and the latent heat storage elements are heated up to the target temperature. The latent heat, storage elements are cooled to an initial temperature below the target temperature and this initial temperature is determined. The latent heat storage elements at the initial temperature are introduced into a thermally insulated container and the container is then closed. The interior of the closed container is, or has been, connected to a heating device of which the thermal output which takes effect in the interior of the closed container is known.

  • Publication number: 20150292787
    Abstract: A method is for preconditioning at least one latent heat storage element, which is arranged in a thermally insulated, closed container having a space for accommodating goods to be transported. The latent heat storage element has a target temperature preferably slightly in excess of 0 DEG C. In such an arrangement, it is particularly practical for the accommodation space in the container to be filled with a certain amount of a coolant, particularly ice, and for the container to be closed, and therefore the latent heat storage element located in the container is cooled to the target temperature.

  • Patent number: 8822005
    Abstract: A vacuum insulated panel comprises a filler and a vacuum-tight high-barrier film envelope, with an air-permeable sheet element that serves as a filter material for dust, wherein the sheet element consists of the same material as the sealing layer of the high-barrier film enveloping the vacuum insulated panel and passes through the sealing seams of the high-barrier film, and to a method for producing such a vacuum insulated panel, wherein the sheet element, in the form of a strip preferably folded along a central axis, is placed between two sealing films and is thermally adhesively bonded to the inwardly disposed sealing layers of the sealing films such that a joint is formed between the two sealing films which are sealed together by means of a respective seam on each of perpendicular sides, the strip-shaped sheet element being co-sealed into the seams.

  • Patent number: 8281558
    Abstract: The invention relates to a method for producing an especially panel-shaped vacuum insulation element which is wrapped in a film and is filled with a powder. According to the method, the unmolded, loose powder is filled, particularly poured, into the opening of a bag which is formed from a high-barrier film and is open on one side. A filter material that is permeable to air and impermeable to powder dust is fixed to the internal face of the film bag in the area of the opening of the filled film bag such that the interior of the bag is closed in a dust-tight manner while air can still be discharged. The interior of the dust-tightly closed film bag is then evacuated and the evacuated film bag is air-tightly closed in a vacuum.

  • Patent number: 8047058
    Abstract: The invention is directed to a method and a system for using a thermal measurement method to determine the gas pressure in a vacuum element or in an evacuated body having an envelope and comprising on its exterior a flap delimited by two film faces that are joined together in the region of the free edge of the flap; the system according to the invention is characterized, on the one hand, by the fact that the space between the two film faces of the flap communicates with the space inside the envelope of the vacuum element and is at least partially filled with an open-pored, thin material layer, and, on the other hand, by a device for measuring the gas-pressure-dependent heat exchange coefficient of the flap at the location of the material layer; the invention also relates to the manner of operation of this measuring device.

  • Patent number: 7400999
    Abstract: The invention relates to the determination of the gas pressure in an evacuated thermal insulating board (9) having an insulating core (1) covered by a film (2). The inventive device comprises an assembly, which is integrated between the insulating core and the covering film of the thermal insulating board and which has a body that acts as a heat sink (3) (Al, Co, Fe, ceramic), and the body's thermal conductivity and thermal capacity relative to volume are greater than those of the insulating core. Said assembly also comprises a test layer (4) (0.3 mm nonwoven fabric made of plastic and glass fibers), which is arranged between the heat sink and the covering film and has a defined thermal conductivity that changes according to the gas pressure inside the evacuated thermal insulating board. From the exterior, a sensor device is applied to or pressed against the test device, which is placed inside the evacuated thermal insulating board and which is covered by the covering film.
