Abstract
The present invention relates to a dynamically evacuable, electrically operated device comprising a coherently evacuable region and a temperature-controllable useful region, which is thermally insulated from the ambient temperature by the coherently evacuable region, and also a means for actively maintaining a vacuum, such that the pressure in the coherently evacuable region of the device is constantly within a defined pressure range, said coherently evacuable region making up at least 20% by volume of the total volume which is occupied by a porous and/or cellular insulating material in the device, and said coherently evacuable region comprising at least one organic aerogel and/or organic xerogel.
