    • A refrigeration appliance includes a thermally insulating housing and a thermally insulating door. At least one of the housing and the door define an evacuated interspace and have an evacuated thermal insulation filling the interspace, a shaped, thermoplastic, substantially gas and water vapor impermeable outer cladding, and a shaped, thermoplastic, substantially gas and water vapor impermeable inner cladding. The inner cladding and the outer cladding substantially surround the interspace in a vacuum-tight manner. The cladding can be formed from polyolefins, polyvinylidene chloride, perfluoroalkoxy polymers. For reducing gas permeability, the cladding can be formed from ethylene/vinyl alcohol copolymer, polyacrylonitrile, and polyamide. The claddings can have co-extruded and/or laminated layers. The cladding can include a sputtered metal layer and/or a plastic/metal composite foil. The cladding can be formed from a thermoformed or blow-molded plastic. The insulation can have pressed silica or aerogel plates with a density of between 100 and 150 kg/m3.
    • 制冷装置包括绝热壳体和绝热门。 壳体和门中的至少一个限定了抽空的间隙,并且具有填充空隙的真空绝热,成形的,热塑性的,基本上气体和水蒸气不可渗透的外包层,以及成形的,热塑性的,基本上气体和水蒸气不可渗透的内部 包层 内包层和外包层基本上以真空密封的方式围绕空隙。 包层可以由聚烯烃,聚偏二氯乙烯,全氟烷氧基聚合物形成。 为了降低透气性,包层可以由乙烯/乙烯醇共聚物,聚丙烯腈和聚酰胺形成。 包层可以具有共挤出和/或层压层。 包层可以包括溅射的金属层和/或塑料/金属复合箔。 包层可以由热成型或吹塑成型的塑料形成。 绝缘体可以压制密度在100至150kg / m 3之间的二氧化硅或气凝胶板。
