According to the ultra-high-speed train cabin air circulation system with the self-pressurization capacity, the two electric compressors and the booster type turbine (2) are adopted, the turbine inlet pressure and the refrigerating capacity are greatly improved, a cabin pressure adjusting valve controls the pressure in a cabin to be stable, and the air circulation efficiency is improved. According to the system, the functions of pressurization, pressure stabilization and temperature adjustment (refrigeration and heating) can be provided for a train cabin, a comfortable temperature and height environment is provided for cabin members, the uncomfortable symptoms such as hearing impairment and altitude stress of the members when a train is in high-speed and low-air-pressure environments are avoided, and the train cabin is suitable for being popularized and used. According to the system, the fresh air circulation amount of the cabin is greatly increased, and the air quality in the cabin is improved.

    本发明是一种具有自增压能力的超高速列车舱室空气循环系统,本发明系统采用两台、两级电动压缩机和一台升压式涡轮机(2),大大提高了涡轮入口压力和制冷量,舱室压力调节活门控制舱室内压力稳定,同时排出废气用于两级电动压缩机冷却,本发明系统能够为列车舱室提供增压、稳定压力和调温(制冷、制热)功能,为舱室成员提供舒适的温度和高度环境,避免列车在高速、低气压等环境下,成员出现听力障碍和高原反应等不适症状,该系统大幅提高了舱室新风循环量,改善了舱室内空气品质。
