Liquid hydrogen is discharged from the liquid hydrogen storage tank (1) and is divided into two paths, and the first path enters the air temperature type vaporizer (8) through the first electromagnetic valve (5) and the heat exchanger (7); the second path passes through a bypass valve (6) and directly enters an air temperature type vaporizer (8). When the interior of the heat insulation compartment (17) needs refrigeration, the liquid hydrogen releases cold energy to the refrigerant through the heat exchanger (7) in the first path, and the refrigeration task is completed. When the temperature displayed by the temperature sensor (16) reaches the target temperature, the first electromagnetic valve (5) is closed, the bypass valve (6) is started to switch to the second path, and the liquid hydrogen directly enters the air-temperature vaporizer (8) and is heated to the normal-temperature hydrogen. The second electromagnetic valve (9) is opened, and the normal-temperature hydrogen gas is stored in the buffer tank (10). According to the hydrogen demand of the fuel cell system (12), the opening degree of the third electromagnetic valve (11) is controlled to complete hydrogen supply.
In the compartment refrigeration system, the refrigerant absorbs liquid hydrogen cold in the heat exchanger (7) and then transfers the cold to the ambient air in the air temperature type heat exchanger (14), and the cold transfer process is liquid hydrogen → the refrigerant → the air in the compartment. The refrigeration system is powered by a pump (13) to complete the cycle.
