摘要： A heat pump air conditioning system and a control method. The heat pump air conditioning system includes: a compressor (1); an indoor unit heat exchanger (2), an outdoor unit heat exchanger (3) and a throttling device (4); a refrigerant circulation loop, connecting the compressor (1), the indoor unit heat exchanger (2), the outdoor unit heat exchanger (3) and the throttling device (4) in series; the heat storage module (5), disposed in the refrigerant circulation loop and configured to absorb heat from refrigerant in the refrigerant circulation loop and store heat when heat storage defrosting is required, and to heat the refrigerant in the refrigerant circulation loop when the outdoor unit heat exchanger is defrosted. The heat pump air conditioning system can store excess heat of the system for defrosting when indoor heat load is low, and release heat for defrosting by means of the heat storage module during a defrosting processwhile continuing supplying heat to a room to ensure that room temperature remains unchanged, thereby improving comfort of the room.
