2.33 Start-Up sequence control of the compressor
In order to avoid the compressors of the air conditioning units in all the carriages from being started simultaneously and avoid serious overload of an alternating current load caused by an auxiliary power supply system, the compressors of the air conditioning units need to be started in a time-staggered manner through a vehicle control system. The staggered starting control is performed by the power units, one power unit controls 6 air-conditioning compressors (2 compressors in each compartment) in 3 compartments, the vehicle control system performs cycle according to a large period of 18 seconds, and 6 time windows with the length of 2 seconds are arranged in each period and respectively correspond to the 6 air-conditioning compressors. Each air conditioner compressor can be started only when the air conditioner compressor belongs to the time window of the air conditioner compressor, and the air conditioner compressor is not allowed to be started at other time. For the air conditioner compressor which is started up, the shutdown process is not controlled by the time window, and the air conditioner compressor can be stopped at any time according to the outdoor environment temperature condition or the control instruction. In addition, an air compressor pre-starting signal is sent out before the air compressor of the braking system is started, and after the air compressor pre-starting signal is detected by the vehicle control system, the starting time windows of all the air conditioners are closed, and the starting operation of all the air conditioners within a period of time is forbidden.
Taking 6 carriages of each railway vehicle as an example, each carriage is provided with two air-conditioning compressors, one power unit controls 6 compressors of 3 carriages, and the 6 carriages have the following serial numbers: fig. 2 shows a timing chart of staggered start of 6 compressors in a TC-Mp-M-Mp-TC, 3-section car, where one start cycle is 18S, one compressor in the TC car starts in a first 2S time window, after 1S, one compressor in the Mp car starts in a second 2S time window, after 1S, one compressor in the M car starts in a third 2S time window, after 1S, the other compressor in the TC car starts in a fourth 2S time window, and so on until all compressors start in a staggered time.
2.4 control of air-conditioner operation mode
2.41 control of Pre-refrigeration or Pre-heating modes

When the air conditioner is started for the first time, firstly, judging whether precooling or preheating is needed; if the actual indoor temperature is more than 27 ℃ and the outdoor environment temperature is more than 30 ℃, controlling the air conditioner to operate in a pre-cooling mode; if the actual indoor temperature is less than 13 ℃ and the outdoor environment temperature is less than 10 ℃, controlling the air conditioner to operate in a preheating mode;
when the indoor target temperature is reached, or the pre-cooling or pre-heating time reaches a set time (for example, 15 minutes), the pre-cooling or pre-heating mode is stopped, and the normal operation mode is entered.
In order to avoid the temperature in the carriage from being too high or too low, the following limiting conditions are set in the air conditioning control system: when the temperature Te outside the automobile is higher than 16 ℃, the heating function is not started, and when the temperature Te outside the automobile is lower than 19 ℃, the refrigerating function is not started.
2.42 control of Emergency Ventilation mode

Under the emergency ventilation mode, the air condition compressor is closed completely, the return air door is closed completely, and the new trend door is opened completely to the operation of 100% new trend mode.
2.43 control of operating mode in fire
Smoke detectors are arranged in the passenger room and outside the vehicle, and the smoke detectors are connected with an air conditioner control system. When a fire is detected, the air conditioning control is as shown in table 3:
TABLE 3 air-conditioning mode in fire
| Fire scene | Corresponding air conditioning mode |
| Fire disaster outside vehicle | And closing the fresh air inlet of the air conditioner, and continuously operating the fan and the compressor in the current mode. |
| In-vehicle fire | And stopping the air conditioner of the fire-occurring compartment. |
The air conditioner control system and the vehicle control system are communicated through an MVB network, when the communication network fault is detected, the air conditioner continues to operate in the current mode, and the network fault is reported.
2.44 control of Ventilation mode
