Thermal management system and thermal management control method of hydrogen refueling station

Abstract

The invention discloses a thermal management system and a thermal management control method of a hydrogen refueling station, and belongs to the technical field of hydrogen refueling station equipment. The thermal management system of the hydrogen refueling station comprises a first temperature sensor, a second temperature sensor, a cooling liquid pump, an industrial refrigerating machine and a thermal management controller. The heat management controller is provided with a chip and can control the rotating speed of the cooling liquid pump and the refrigerating power of the industrial refrigerating machine according to temperature data of the first temperature sensor and/or the second temperature sensor so as to control the temperature of hydrogen at outlets of a compressor and a pressure reducing valve. Through continuous exploration and tests, the thermal management system for the external hydrogen supply hydrogen refueling station is arranged, and the temperature of hydrogen at the outlets of the compressor and the pressure reducing valve can be accurately and integrally controlled. Only one set of cooling liquid pump and industrial refrigerating machine is needed, double cooling arrangement of hydrogen compression and high-pressure hydrogen pressure reduction can be achieved, and energy consumption and cost of thermal management of the hydrogen refueling station are effectively reduced.

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...
