The invention discloses a multi-temperature-zone air supply heat pump air conditioning system and a control method thereof, and belongs to the technical field of electric automobile air conditioners. The system comprises a refrigerating system, an air supply system and an electric control unit. The refrigerating system comprises an inverter compressor, a liquid storage device, an outdoor heat exchanger, a heat regenerator and a four-way reversing valve. An outlet of the heat regenerator is connected with a first throttling device and a second indoor heat exchanger, and an outlet of the first throttling device is connected to the first indoor heat exchanger. The first indoor heat exchanger and the second indoor heat exchanger are connected to an air supply system; the air supply system comprises a fan, a first air supply outlet and a third air supply outlet; an inlet of the first indoor heat exchanger is connected with the third air supply outlet; an outlet of the first indoor heat exchanger is connected with the first air supply outlet and the second air supply outlet. According to the multi-temperature-zone air supply system, multiple kinds of different-temperature air supply are obtained through a pre-matched and designed double-heat-exchanger structure and middle throttling, temperature adjustment is further conducted through electric heating, and therefore multi-temperature-zone air supply is achieved.
