CRYOGENIC AEROGEL INSULATION SYSTEM

摘要

A method for establishing a cryogenic insulation system wherein aerogel is provided to a sealable insulation space (1) defined by an inner and outer wall (2, 3) which is pressurized and depressurized. The pressurization is accomplished by preferably using a condensable gas, preferably carbon dioxide, provided to the insulation space (1). The condensable gas is cooled to depressurize the insulation space by cooling at least one wall (2, 3) to a temperature less than 190K and cooled to cryogenic temperatures typically by the application of refrigeration from cryogenic liquid.
