The invention discloses a rail train air conditioner control system and a control method, and belongs to the technical field of vehicle-mounted electrics.The rail train air conditioner control system comprises an inversion unit, a draught fan and an air conditioner control unit; the inverter unit is electrically connected with the fan through a first contactor; the inversion unit comprises an input filter, a booster circuit, an inversion circuit, an output filter, a time delay relay, a second contactor, a current limiting resistor and an internal control module; a second contactor and a current-limiting resistor which are connected in parallel are arranged between the input filter and the booster circuit; the input end of the delay relay is electrically connected with the air conditioner control unit, and the output end of the delay relay is electrically connected with the end, close to the input filter, of the current-limiting resistor and the internal control module. The internal control module is electrically connected with the second contactor and the booster circuit. The start control logic of the vehicle-mounted inverter is optimized, simultaneous time delay of software and hardware is realized, frequency modulation and voltage regulation soft start of the vehicle-mounted inverter is really realized, and the service life of a fan is prolonged.
