The invention discloses a low-vacuum pipeline train, which comprises an air entraining system, a low-vacuum pipeline system, a low-vacuum pipeline system and a low-vacuum pipeline system, the refrigeration system comprises a pressurization module, a heat exchange module and a turbine, an air inlet of the pressurization module is communicated with an air outlet of the air entraining system, an air outlet of the pressurization module is communicated with a hot side inlet of the heat exchange module, and a hot side outlet of the heat exchange module is communicated with an inlet of the turbine; air in the compartment circulates on the hot side of the cabin air heat exchanger, and an inlet on the cold side of the cabin air heat exchanger is communicated with an outlet of the turbine. High-temperature and low-pressure air in the low-vacuum pipeline is actively compressed, then the heat exchanger and the turbine are used for cooling to obtain low-temperature air, the low-temperature air serves as a cold source of the cabin air temperature adjusting system, oxygen and the cold source do not need to be additionally carried, it is guaranteed that the temperature in a passenger cabin is within a proper range, and the comfort of passengers is improved.
一种低真空管道列车,包括:引气系统,所述引气系统具有设置在车厢外的进气口;制冷系统,所述制冷系统包括增压模块、换热模块和涡轮,所述增压模块的进气口与所述引气系统的出气口连通,所述增压模块的出气口与所述换热模块的热侧进口连通,所述换热模块的热侧出口与所述涡轮的进口连通;以及座舱空气换热器,所述座舱空气换热器的热侧循环流通所述车厢内的空气,所述座舱空气换热器的冷侧进口与所述涡轮的出口连通。本发明通过主动压缩低真空管道内的高温低压空气,再通过换热器和涡轮进行降温获取低温空气,作为座舱空气调温系统的冷源,无需额外携带氧气和冷源,保障客舱内温度在适宜的范围内,提高乘客舒适性。
