Thermal management system and control method thereof, storage medium, controller and vehicle

The invention discloses a heat management system and a control method thereof, a storage medium, a controller and a vehicle. When the heat management system is in a refrigerant flushing state, an inlet of a liquid storage tank communicates with an exhaust port of a compressor, and an outlet of the liquid storage tank communicates with an air suction port of the compressor; when the thermal management system satisfies a first condition, the thermal management system is in a battery heating state. Therefore, the refrigerant flushing state is set before the battery heating state, when the battery needs to be heated, the heat management system is in the refrigerant flushing state firstly, and a high-temperature and high-pressure refrigerant discharged by the compressor can take out the refrigerant in the liquid storage tank, so that the refrigerant in the liquid storage tank can participate in heat exchange of the heat management system; the quantity of refrigerants participating in circulating heat exchange in t
