The invention discloses a CO2 heat pump air conditioner whole vehicle heat management system. The invention discloses a CO2 heat pump air conditioner whole vehicle heat management system which comprises an in-vehicle refrigeration loop, wherein the in-vehicle refrigeration loop is configured to enable a refrigerant to circularly flow through a compressor; an outdoor heat exchanger;a liquid-gas separator with a heat regeneration function; an expansion valve;an evaporator; and a liquid-gas separator with a heat regeneration function. The system further comprises a heat pump in-vehicle heating loop which is configured to enable a refrigerant to flow according to the sequence of the compressor, the indoor heat exchanger, the evaporator, the expansion valve, the liquid-gas separator with the heat regeneration function, the outdoor heat exchanger and the liquid-gas separator with the heat regeneration function. The CO2 heat pump air conditioner vehicle thermal management system provided by the invention has multiple working modes and can realize a linked battery thermal management function. The system can solve the problems that a heat pump air conditioning system is poor in heating effect and defrosting effect under the low-temperature working condition.
