The invention discloses a rail transit vehicle and an air conditioning system and a control method thereof. The air conditioning system comprises an air conditioning unit and a heating unit. The heating unit comprises a heat exchanger, a cooling liquid tank, a water pump and a plurality of heaters; a first control valve is arranged at the first end of the heat exchanger, a second control valve is arranged at the end, connected with the first end of the heat exchanger, of the evaporator, a first one-way valve is arranged at the second end of the heat exchanger, a third control valve is arranged at the water inlet end of each warmer, and a second one-way valve is arranged at the water outlet end of each warmer. The first control valve, the second control valve, the third control valve and the water pump are connected with an air conditioner controller, and the air conditioner controller controls opening and closing of the first control valve, the second control valve, the third control valve and the water pump according to the working mode of the air conditioning unit. A heat pump heating mode is adopted to replace a traditional seat electric heating mode, and the heating effect of the lower portion of the passenger room is guaranteed while the power consumption of an air conditioner is not increased.
