Heat management system

A heat management system comprising:

• a refrigerant circulation line including a compressor, a water-cooled condenser, a first expansion valve, an air-cooled condenser, a second expansion valve, an evaporator, a refrigerant heat exchanger heat-exchanging a refrigerant flowing into the second expansion valve and the refrigerant discharged from the evaporator with each other, and a first refrigerant bypass line allowing the refrigerant passing through the water-cooled condenser to bypass the first expansion valve and the air-cooled condenser, and circulating the refrigerant to cool an indoor area;
• a heating line heating the indoor area by circulating a coolant heat-exchanged with the refrigerant through the water-cooled condenser;
• a first cooling line cooling a battery by circulating the coolant heat-exchanged with air or the refrigerant;
• and
• a second cooling line cooling an electric component including a drive motor by circulating the coolant heat-exchanged with air or the refrigerant.
