Thermal management system for vehicle

A thermal management system for a vehicle, the thermal management system comprising:

• a base circuit in which a compressor, a condenser, an expansion valve, and an evaporator are provided in order, wherein a refrigerant is circulated in the base circuit;
• a recirculation circuit branched from a discharge portion of the compressor in the base circuit and joined to the compressor or an inlet portion of the compressor so that the refrigerant discharged from the compressor is recirculated to an inlet of the compressor;
• and
• an adjusting valve positioned at the discharge portion where the recirculation circuit is branched from the base circuit or positioned at the inlet portion where the recirculation circuit is joined to the base circuit, the adjusting valve configured to adjust a flow rate of the refrigerant that flows to the recirculation circuit,
• an ejector positioned at the inlet portion where the recirculation circuit is joined to the base circuit, the ejector configured to perform suction of the refrigerant in the base circuit by use of flowing of the refrigerant in the recirculation circuit,
• wherein the base circuit has a flash tank which is provided between the condenser and the evaporator, and the thermal management system further includes a flash circuit branched from the flash tank of the base circuit and joined to the recirculation circuit so that the refrigerant in a gaseous state separated in the flash tank flows to the recirculation circuit, and
• wherein the thermal management system further includes a shutoff valve provided in the flash circuit between the flash tank and the ejector, the shutoff valve configured to adjust the flow rate of the refrigerant that flows to the flash circuit.
