Abstract

The invention discloses a thermal management system and a thermal management control method of a hydrogen refueling station, belonging to the technical field of hydrogen refueling station equipment. A thermal management system of a hydrogen refueling station of the present invention includes a temperature sensor 1, a temperature sensor 2, a cooling liquid pump, an industrial refrigerator, and a thermal management controller. The thermal management controller is provided with a chip, which can control the rotation speed of the cooling liquid pump and the refrigeration power of the industrial refrigerator according to the temperature data of the temperature sensor 1 and / or the temperature sensor 2, so as to control the temperature at the outlet of the compressor and the pressure reducing valve. the temperature of the hydrogen. After continuous exploration and testing, the present invention is equipped with a thermal management system for external hydrogen supply and refueling stations, which can precisely and integratedly control the hydrogen temperature at the outlet of the compressor and the outlet of the pressure reducing valve. The invention only needs a set of cooling liquid pump and industrial refrigerator to realize dual cooling settings of hydrogen compression and high-pressure hydrogen decompression, effectively reducing the energy consumption and cost of thermal management of hydrogen refueling stations.

Description

technical field [0001] The invention relates to a thermal management system and a thermal management control method of a hydrogen refueling station, belonging to the technical field of hydrogen refueling station equipment. Background technique [0002] At present, in the construction process of hydrogen energy refueling station, the integration and control of key equipment are mainly realized, and the thermal management system of various equipment has not been comprehensively designed and controlled; generally, the outlet of the compressor and the pressure reducing valve in the hydrogen refueling station need to be assembled separately. Thermal management equipment, resulting in redundant configuration of thermal management equipment in hydrogen refueling stations, increased energy consumption and cost of thermal management of hydrogen refueling stations, which is not conducive to popularization and use. Contents of the invention [0003] In view of the defects of the prio...
