Disclosed is a vehicle heat pump system that has good air conditioning efficiency, can significantly reduce the size of an air-cooled condenser compared to conventional ones, and has great advantages in cost reduction and package reduction. The vehicle heat pump system comprises: a refrigerant line which circulates through a compressor, an outdoor heat exchanger, an expansion means, and an indoor heat exchanger, and 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 and 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 electronic component and an electronic radiator, the system also including a water-cooled condenser which thermally exchanges engine heat from the first coolant line with the refrigerant, and a chiller which thermally exchanges electronic heat from the second coolant line with the refrigerant, wherein the water-cooled condenser is provided downstream of the compressor in the refrigerant flow direction, and the chiller is provided upstream of the compressor in the refrigerant flow direction.
