The invention discloses a vehicle carbon dioxide mixed working medium heat pump air conditioner component regulation and control system and method. The system comprises a heat pump unit and a component regulation and control unit. The heat pump system unit comprises a compressor, a first heat exchanger, a four-way valve, an evaporator/air cooler, a heat regenerator, a first throttle valve, an evaporator/condenser and a first gas-liquid separator; and the component regulation and control unit comprises a second throttle valve, a second gas-liquid separator, a second heat exchanger, a first regulation tank, a second regulation tank and a three-way valve. By the adoption of the technical scheme, when the refrigerating and heating modes are converted, the throttling gas-liquid phase components and the components in the adjusting tank are collected and released, the component adjusting and controlling effect is achieved, then the system performance is improved, and energy conservation and emission reduction are promoted.
