Abstract:
Air permeable core material is vacuum sealed in enveloping member. Further, core material is formed of at least two layers of heat insulating core materials having different heat conductivities. Further, at least two of the at least two layers of heat insulating core materials which form core material are formed of materials having change gradients in the heat conductivity changed in accordance with temperature, and the change gradients in the heat conductivity of the heat insulating core materials intersect with each other. Since two layers of heat insulating core materials having different heat conductivities are provided in a vacuum state, a heat insulating property becomes higher compared to a conventional configuration in which a single layer of the heat insulating core material formed of fiber material such as glass wool or rock wool is vacuum sealed and the high heat insulating property is shown in a wide temperature range.
Abstract:
An insulated cabinet structure includes an inner liner having a plurality of walls defining a refrigerator compartment. An external wrapper includes a plurality of walls defining a refrigerator compartment receiving area. An insulation gap is formed between the walls of the inner liner and the walls of the external wrapper when the inner liner is received in the external wrapper. An insulation member is positioned within the insulation gap and includes a renewable resource component comprising about 10% to about 90% by weight of the insulation member.
Abstract:
An evacuated panel is provided for thermal insulation of a body (3, 4) having non-planar surfaces, the panel having two main faces and comprising a flexible envelope (1), made of one or more barrier sheets, and a filling material formed of at least two boards (2; 2′) of an open cell polymeric foam, the boards lying one over the other, and each board having a thickness between about 2 and 8 mm.
Abstract:
A domestic refrigeration appliance, such as a refrigerator, freezer or the like, comprising a door and with vacuum heat insulation interposed between a substantially vacuum-tight inner shell and a substantially vacuum-tight outer shell; the two shells are joined together vacuum-tight on that side towards the door by means of a flange-like extension provided on one of said shells and welded vacuum-tight to the other shell.
Abstract:
A container has a base, peripheral walls and a lid. Each of the base, peripheral walls and lid includes an interior wall spaced from an exterior wall, with vacuum panel in between. The sides of the vacuum panels are covered by compressible insulation fill, minimizing thermal flow along the vacuum panels despite any manufacturing tolerance differences in the width of the vacuum panels as compared to the distance between the interior wall and the exterior wall. The interior wall of the body of the container is provided by a liner formed of a single, deep drawn sheet of material. The exterior wall is similarly formed as a deep drawn shell. The inner liner and the outer shell are welded together with a bead to encase the vacuum panels in a water-tight manner, with the liner, the shell the bead all formed of the same material.
Abstract:
A getter system is provided for use with an evacuated container such as a vacuum insulation panel. The getter system has a first, activated getter material capable of gettering at least a first gas or vapor and a second, different gas or vapor. The getter system also has a second, activated getter material capable of gettering the first, but not the second, gas or vapor. Finally, the getter system includes packaging for the first and second getter materials, such that the first and second getter materials may be placed together within a single compartment of the evacuated container and the second getter material will be more readily exposed to the first gas or vapor than the first getter material. In this manner, the first getter material will be protected from the first gas or vapor even though it is already activated.
Abstract:
The invention disclosed in the present specification relates to urethane that has insulation performance improved by lowering the thermal conductivity of urethane, and to a refrigerator having same applied thereto. The urethane having improved insulation performance comprising a plurality of closed cells containing internal gas generated from foaming; a plurality of open cells connected to outside air; and cell walls arranged between a closed cell among the plurality of closed cells and an open cell among the plurality of open cells or between the plurality of closed cells to connect the closed cells and the open cells, or the plurality of closed cells; and have a thermal conductivity (λurethane) 17 to 18.5 mW/m·K.
Abstract:
An insulated cabinet structure includes an inner liner having a plurality of walls defining a refrigerator compartment, and an external wrapper having a plurality of walls defining a refrigerator compartment receiving area. An insulation gap is formed between the walls of the inner liner and the walls of the external wrapper. A first insulation material is positioned on a wall of the external wrapper and extends outwardly into the insulation gap to partially fill the insulation gap. The first insulation material includes a renewable resource component having a particle size in a range from about 10 microns to about 25 microns. A second insulation material is disposed in the insulation gap, such that the first insulation material and the second insulation material together substantially fill the insulation gap.
