Abstract:
A vacuum insulation panel (100) includes a blended wool media (106) made up of fibers (110, 112) having at least two different average fiber diameters. The blended wool media (106) includes smallfibers (110) which improve thermal performance of a vacuum insulation panel (100) and large fibers (112) which improve the mechanical strength of the insulating media (106) and reduce the time required to produce a vacuum within the panel (100).
Abstract:
Refrigerating cupboard, in particular, of the domestic type, with dual walls, enclosing a thermal insulator, whose inner and outer walls are composed of panels made from a ligneous or timber material, such as solid wood, or elements made from the above material, characterized by having a steam screening panel (7) made from a ligneous or timber material, between the outer casing and the solid thermic-insulating panel (5). The solid steam-screening panel is covered, or impregnated with a steam-screening panel from the exterior to the interior of the cupboard. The outer casing is equipped with a product or an artificial coating material having physical, mechanical or aesthetic properties. The inner casing (6) is covered, or impregnated with a material or a coating product possessing waterproofing properties, as well as air and steam permeating properties.
Abstract:
The present invention relates to an insulation used in home appliances and building materials. A method of manufacturing an insulation includes fabricating an adhesive solution by inputting a binder to water contained in a water tank, inputting long glass fibers to the adhesive solution, removing moisture by supplying the long glass fibers to a mesh belt, wherein the mesh belt move left and right and front and rear so that the long glass fibers are uniformly spread, fabricating glass fiber paper by drying the long glass fibers, winding the glass fiber paper in a roll form, and preparing the glass fiber paper rolls in multiple layers, stacking two or more sheets of the glass fiber paper supplied from the rolls, and sewing the sheets of stacked glass fiber paper.
Abstract:
A rectangular double walled cryogenic freezer (10,110) has a vacuum space (16,116) filled with alternating layers of flexible insulating material (20,120) and a reflective material (18,118). A support structure (22,122) is also positioned in the vacuum space (16,116). The support structure (22,122) is open-celled and provides structural support for the freezer walls to prevent wall deformation when a vacuum is drawn. The support structure (22,122) may be open-cell rigid foam (122) or a support grid (22) sandwiched between two layers of rigid insulation material (26a,26b).
Abstract:
By using vacuum heat insulator comprising a core made of laminated sheets of an inorganic fiber having a particular shape and composition as a vacuum heat insulator for a heat insulation box, a heat insulation box excellent in long-term heat insulating property and productivity can be provided. The vacuum heat insulator can be shaped easily. Therefore, a vacuum heat insulator suitable for a required heat insulation portion can be produced easily and applied to a heat insulation box. This property can increase coverage of the vacuum heat insulator on the heat insulation box, thus improving the heat insulating property of the heat insulation box. This can improve the heat insulating property and productivity of a refrigerator, thermal storage box, cold storage box, or vending machine, and contribute to an energy saving.
Abstract:
Vacuum heat insulator comprising a laminated core made of a plurality of sheets of inorganic fibers having 10 µm or smaller in diameter and a certain composition including SiO 2 as a main component, Al 2 O 3 , CaO, and MgO, a gas barrier enveloping member, and an absorbent. The vacuum heat insulator is characterized by having at least one groove formed therein after fabrication of the vacuum heat insulator. Further, the vacuum heat insulator is characterized by using inorganic fiber core of which a peak of distribution in fiber diameter lies between 1 µm or smaller and 0.1 µm or larger, and not containing binding material for binding the fiber material. Electronic apparatuses of the present invention use the vacuum heat insulator. With use of the vacuum heat insulator, electronic and electric apparatuses superior in energy saving and not to present uncomfortable feeling to the user can be provided.
Abstract:
Ein Wärmeisolationselement (1) mit parallel zueinander liegenden Wandflächen (2) und dazwischen angeordneten Stützmitteln (12) ist im Randbereich mit Abschlußmitteln (3, 7) versehen, wobei der Raum zwischen den Wandflächen (2) weitgehend evakuiert ist. Um einen thermisch hochwertigen Abschluß im Randbereich zu erreichen, ist eine wenigstens gegenüber einem Rand (5) der Wandfläche (2) zurückgesetzte Membran (3) vorgesehen, die von einer Membranabdeckung (7) geschützt ist, wobei die Membran wie die Membranabdeckung aus schlecht wärmeleitendem Material bestehen.
Abstract:
Un panneau isolant (10) comprend un panneau de fibres minérales (12) d'une densité comprise entre 8 et 28 livres par pied carré (0,128 et 0,449 gm/cm3), les fibres ne comportant pas de liant organique, et entre 5 et 40 % en poids d'un mßteriau particulaire (16) tassé dans les interstices du panneau, et une enveloppe étanche au gaz (14) englobant le panneau (12). On fait le vide dans cette enveloppe (14) jusqu'à un niveau de vide situé entre 10-4 Torr et 10 Torr.
