The invention provides a refrigerant backflow control method and system of a heat pump system, a storage medium and a vehicle. According to one embodiment of the invention, the method comprises the steps that when a heating request is responded, a heat pump system enters a heating mode, and a compressor is started for heating, the saturation temperature of a refrigerant in an evaporator and the suction pressure of the compressor are obtained; according to the saturation temperature of the refrigerant in the evaporator, the corresponding refrigerant saturation pressure is obtained by looking up the refrigerant physical property table; when the refrigerant saturation pressure is lower than the compressor suction pressure and it is determined that the evaporator liquid accumulation risk exists, whether risk conditions influencing the heating capacity and the system state exist or not is further determined; and when it is determined that the risk condition influencing the heating capacity and the system state exists, an evaporator loop is controlled to be opened. According to the invention, refrigerant backflow control can be effectively carried out.
