The present invention provides a heat pump system for a vehicle comprising: a refrigerant circulation line in which a compressor, a water-cooled condenser, an expansion valve and an evaporator are arranged, and a refrigerant circulates to cool the room; and a cooling water circulation line having a heating line for heating the room by circulating cooling water exchanged with the refrigerant through the water-cooled condenser, and a cooling line for cooling a battery and electronic components by circulating air or cooling water exchanging heat with the refrigerant. A reservoir tank through which the cooling water of the heating line and the cooling water of the cooling line passes is disposed in the cooling water circulation line. There is an effect that can increase the heat exchange efficiency.
