HEAT PUMP SYSTEM FOR VEHICLE

Heat pump system for a vehicle comprising a refrigerant line circulating through a compressor, an outdoor heat exchanger, an expansion means, and an indoor heat exchanger, in which a refrigerant circulating through the indoor heat exchanger exchanges heat with air discharged to the interior; a first coolant line which circulates through an engine and a heater core in which a coolant circulating through the heater core exchanges heat with the air discharged to the interior; and a second coolant line which circulates through an electric components and an electric radiator, a water-cooled condenser which exchanges heat between engine heat of the first coolant line and the refrigerant; and a chiller provided upstream of the compressor in the refrigerant flow direction which exchanges heat between electric heat of the second coolant line and the refrigerant, wherein the water-cooled condenser is provided downstream of the compressor in the refrigerant flow direction.
