Abstract:
The present invention relates to a dynamically evacuable, electrically operated apparatus comprising a contiguously evacuable region and a working region whose temperature can be controlled and which is thermally insulated by the contiguously evacuable region from the ambient temperature, and also a means for actively maintaining a vacuum so that the pressure in the contiguously evacuable region of the apparatus is constant over time within a prescribed pressure range, where the contiguously evacuable region makes up at least 20% by volume of the total volume occupied by a porous and/or cellular insulation material in the apparatus and the contiguously evacuable region comprises at least one organic aerogel and/or organic xerogel.
Abstract:
The present invention relates to vacuum insulation units containing at least one heat-insulating, evacuated, air-tightly closed, porous core material and a sorption agent. Said sorption agent comprises at least one porous organometallic skeleton material, which contains at least one at least bidentate organic compound that coordinatively bonds to at least one metal ion, and moulded bodies containing such a vacuum insulation unit. The present invention further relates to the use of a porous organometallic skeleton material as a getter material in a vacuum insulation unit.

Abstract:
A transport container for transporting an object includes an object location to receive the object and a vacuum insulation panel (VIP) to thermally insulate the object location. A sensor unit in the VIP provides a panel condition signal that corresponds to a measurement value of a physical property of the VIP. The physical property influences temperature of the object. A short-distance transmitter unit transmits a first coding of the PCS inside the Container, a long-distance transmitter unit transmits a second coding of the PCS to a remote server for processing the PCS. The server determines a representation of an operation state of the transport container, wherein the operation state is related to the temperature of the object. The material of the VIP is classified and differentiated so that transmitting parameters depend on the material.
Abstract:
Un contenedor de transporte (100) para transportar un objeto (105) tiene una ubicación del objeto (104) para recibir el objeto (105) y un panel de aislamiento al vacío VIP (102-i) con el fin de aislar térmicamente la ubicación del objeto (104). Una unidad de sensor (120-i) en el VIP proporciona una señal de estado del panel (PCS, 125-i) que corresponde a un valor de medición de una propiedad física del VIP. La propiedad física influye en la temperatura del objeto (? OBJETO). Una unidad transmisora de corta distancia (130-i) transmite una primera codificación (135-i) de la PCS dentro del contenedor (100), una unidad transmisora de larga distancia (140) transmite una segunda codificación (145) de la PCS a un servidor remoto (200) para procesar la PSC. El servidor (200) determina una representación de un estado operativo del contenedor de transporte, en el que el estado operativo está relacionado con la temperatura del objeto (? OBJETO). El material del VIP es clasificado y diferenciado de modo tal que la transmisión de parámetros dependa del material.
