The TCMS system outputs different state working modes to the air-conditioning controller according to the internally agreed load logic judgment protocol (this invention is tentatively determined to have 1 to 5 modes, representing the air-conditioning power from low to high, corresponding to the different load interval values ​​corresponding to the train load AW0 to AW4).

[0015] The air conditioning intelligent adjustment and control part mainly realizes different power outputs of the air conditioning under different passenger load states through the TCMS system 3, the air conditioning control system 4, the air conditioning 5, and 6.

The air conditioning units realize working states of different powers through the inverter. At the same time, a temperature sensor is configured at each end of the train to monitor and feedback the car temperature.
