when the running state of the motor train unit is a deceleration station-entering state, controlling the air conditioner to enter a refrigeration frequency-reduction mode; or,
and when the running state of the motor train unit is starting, controlling the air conditioner to enter a refrigeration frequency-boosting mode.
9. The control method of the air conditioner for the motor train unit according to claim 8, wherein the cooling down mode is as follows:
setting a third preset frequency of the air conditioner compressor,
acquiring a third working frequency of the air conditioner compressor,
and controlling the frequency of the air conditioner compressor to be reduced from the third working frequency of the air conditioner compressor to a third preset frequency of the air conditioner compressor at a third speed, and keeping running at the third preset frequency of the air conditioner compressor.
10. The control method of the air conditioner for the motor train unit according to claim 8, wherein the cooling up-conversion mode is:
a second outdoor ambient temperature is obtained and,
setting a fourth preset frequency of an air conditioner compressor based on the second outdoor ambient temperature,
acquiring a fourth working frequency of the air conditioner compressor,
controlling the frequency of the air conditioner compressor to increase from the fourth operating frequency of the air conditioner compressor to a fourth preset frequency of the air conditioner compressor at a fourth speed and keeping running at the fourth preset frequency of the air conditioner compressor.
