Abstract

The invention discloses a hydrogen internal combustion power vehicle and method based on high-pressure hydrogen expansion work and waste heat utilization in order to solve the problem of energy consumption of an air conditioner of a hydrogen internal combustion power vehicle, and the hydrogen internal combustion power vehicle comprises a high-pressure hydrogen storage system, a high-pressure hydrogen refrigeration system, a hydrogen internal combustion power generation system and a traction power system. Cold energy generated in the pressure reduction process of the high-pressure hydrogen is provided for the air conditioning system for refrigeration, expansion work can be converted into electric energy to supplement electric quantity for the power battery, and tail gas heat generated by the hydrogen internal combustion power generation system is provided for the air conditioning heating system. On one hand, cold energy generated by the refrigerating system in the vehicle hydrogen power system is applied to the air conditioner refrigerating system of the vehicle, on the other hand, heat generated by the hydrogen internal combustion engine in the vehicle hydrogen power system is applied to the air conditioner heating system of the vehicle, and waste heat of the internal combustion engine and high-pressure hydrogen expansion work are fully utilized; the air-conditioning energy consumption in the vehicle is greatly reduced, and the comprehensive energy utilization rate of the vehicle is improved.

Description

technical field [0001] The invention relates to a hydrogen internal combustion powered vehicle, in particular to a hydrogen internal combustion powered vehicle based on high-pressure hydrogen expansion work and waste heat utilization. Background technique [0002] As a clean secondary energy source, the application of hydrogen energy in vehicles has attracted widespread attention. However, when hydrogen is used as fuel to drive internal combustion vehicles, a lot of excess energy will be generated. How to make rational use of these excess energy and further reduce the vehicle itself energy consumption, there is still no better solution. High-pressure gaseous hydrogen storage is currently the most commonly used form of hydrogen storage. Before the high-pressure hydrogen stored in the high-pressure tank enters the hydrogen-using equipment, it usually needs to be decompressed to the hydrogen supply pressure required by the hydrogen-using equipment. However, the expansion work ...
