1. A thermal management system for a vehicle, the system comprising:
a compressor provided on a first refrigerant line and configured to compress a refrigerant circulated in the first refrigerant line;
an external condenser provided on the first refrigerant line, connected downstream of the compressor, and configured to release heat of the refrigerant discharged from the compressor through heat exchange with air;
a front evaporator provided on the first refrigerant line, connected downstream of the external condenser, and configured to evaporate the refrigerant through heat exchange with the air;
a second refrigerant line connected to the first refrigerant line and configured to allow the refrigerant discharged from the external condenser to be introduced thereinto and then to be discharged upstream of the compressor;
a rear evaporator provided on the second refrigerant line and configured to selectively release heat of the refrigerant through heat exchange with the air;
a first flow control valve provided on the first refrigerant line and configured to allow the refrigerant discharged from the compressor to be introduced into the rear evaporator or the external condenser; and
a second flow control valve provided on the second refrigerant line and configured to allow the refrigerant discharged from the rear evaporator to be introduced into the compressor or the external condenser.
