Verfahren und Vorrichtung zur Betankung von Fahrzeugen

摘要

Liquid-containing tanks of vehicles can be filled with supercooled liquid (eg liquid hydrogen fuel), the supercooling being effected by heat exchange with low-temperature liquefied gas such as liquid nitrogen. The filling is initiated from a pressurized storage container 2 containing cryogenic liquid 1 in the boiling state and carried out while maintaining the pressure. Nitrogen can be used as the low-temperature liquefied gas for the supercooling, alternatively natural gas, methane or a mixture of the two can be used. The apparatus comprises a storage container 2, a transfer pipe 3, a heat exchanger 4 and a flexible pipe 7 which is connected to the liquid-containing tank 8 of the vehicle during filling.
