A heat pump system for a vehicle is provided. The system includes a battery coolant line connected to a battery module. A cooling device selectively connected to the battery coolant line includes a radiator and a first water pump, to circulate a coolant therein. A first chiller is disposed in the battery coolant line and connected to a refrigerant line of an air conditioner to adjust a temperature of a coolant. A second chiller is selectively connected to the coolant line and selectively connected to the refrigerant line to increase a temperature of a coolant by selectively exchanging heat between the coolant and a refrigerant flowing into the second chiller. An integrated control valve is connected to the refrigerant line, the first connecting line, and the second connecting line to adjust a refrigerant flow direction and to selectively expand a refrigerant passing through the integrated control valve.
