| 摘要 |
The invention relates to a filling station (1) adapted for filling of a liquid cryogenic refrigerant from a supply tank to a receiver tank, the filling station (1) comprising a flash tank (2) positioned between the supply tank and the receiver tank, this flash tank (2) being adapted to de-pressurize the liquid cryogenic refrigerant that is transferred from the flash tank (2) to the receiver tank, resulting in the formation of a liquid cryogenic refrigerant phase (21) and a vapour cryogenic refrigerant phase (22) within the flash tank (2), and to phase separate the liquid and vapour cryogenic refrigerant phase (21, 22), and a pump (5) positioned between the flash tank (2) and the receiver tank, the pump (5) being adapted for pumping the liquid cryogenic refrigerant out of the flash tank (2) to the receiver tank, wherein the flash tank (2) is equipped with a level control unit that is arranged to keep the level of the liquid cryogenic refrigerant phase within the flash tank (2) at a predetermined minimum. |
