Abstract
Provided is a hybrid refueling station, including: a liquefied fuel unit, a gaseous fuel unit, a temperature management system and a dispensing unit. By combining the liquefied fuel unit with the gaseous fuel unit, boil-off fuel from the liquefied fuel unit is recovered into the gaseous fuel unit, which avoids boil-off loss of liquefied fuel. Provided also is a method for refueling in a hybrid refueling station. By using the gaseous fuel unit to perform a refueling operation during start-up of the liquefied fuel unit, the problem in the prior art of a delay during start-up when the liquefied fuel unit is used is overcome.
Claims17
A hybrid refueling station, comprising:
- a liquefied fuel unit, which comprises at least one liquefied fuel storage device, a vaporization device and a first gas storage subunit, wherein the liquefied fuel storage device is connected with the first gas storage subunit via the vaporization device, and the first gas storage subunit is used for storing vaporized fuel;
- a gaseous fuel unit, which comprises at least one gaseous fuel storage device, a pressurization device and a second gas storage subunit, wherein the gaseous fuel storage device is connected with the second gas storage subunit via the pressurization device, and the second gas storage subunit is used for storing pressurized gaseous fuel;
- a temperature management system, which comprises a gas inlet and a gas outlet, wherein the gas inlet is connected to the liquefied fuel unit and the gaseous fuel unit respectively for adjusting a temperature of gas discharged from the liquefied fuel unit and the gaseous fuel unit;
- and
- a dispensing unit, which is connected to the gas outlet of the temperature management system for dispensing gas from the temperature management system,
- wherein boil-off fuel from the liquefied fuel unit is recovered to the gaseous fuel unit.
