Abstract

The application discloses a kind of liquid hydrogen fast precooling system and method using non-condensable gas, belong to liquid hydrogen technical field.The liquid hydrogen fast precooling system includes liquid hydrogen booster pipeline, liquid hydrogen supply tank, liquid hydrogen filling pipeline, fast cooling liquid hydrogen pipeline, liquid hydrogen filling tank main body structure, non-condensable gas pipeline, high-pressure non-condensable gas bottle and controller.The system uses external input intermittent low-temperature non-condensable gas, effectively suppresses the gas film phenomenon generated in liquid hydrogen precooling process, improves heat exchange efficiency;The opening of liquid hydrogen solenoid valve is controlled in the specified range by controller, and the liquid hydrogen flow and pressure of precooling process are regularly changed, so that the control of liquid hydrogen superheat is realized, and the stable gas film formed is further destroyed.
