[0002] At present, hydrogen refueling stations need to compress hydrogen during hydrogen filling. During the process of hydrogen compression, due to the Joule-Thomson effect of hydrogen, a large amount of heat energy is generated. The existence of this part of heat energy will not only lead to the increase of The temperature of the vehicle-mounted gas cylinder affects the safety, filling efficiency and filling volume of the gas cylinder. At the same time, if the compressed hydrogen is directly pre-cooled to a low temperature, this part of the heat will be lost and energy will be wasted. The hydrogen station can collect this part of heat accordingly for subsequent use

Description
technical field [0001] The invention belongs to the technical field of thermal energy utilization, and in particular relates to a thermal energy collection and utilization system of a hydrogen refueling station. Background technique [0002] At present, hydrogen refueling stations need to compress hydrogen during hydrogen filling. During the process of hydrogen compression, due to the Joule-Thomson effect of hydrogen, a large amount of heat energy is generated. The existence of this part of heat energy will not only lead to the increase in hydrogen filling The temperature of the vehicle-mounted gas cylinder affects the safety, filling efficiency and filling volume of the gas cylinder. At the same time, if the compressed hydrogen is directly pre-cooled to a low temperature, this part of the heat will be lost and energy will be wasted. The hydrogen station can collect this part of the heat for subsequent use. [0003] Moreover, in addition to the heat produced during hydrogen...
