Abstract
A vehicle heat pump system is provided. The system includes a battery coolant line connected to a battery module and into which a coolant flows. A cooling device includes a radiator and a first water pump connected to a coolant line, to circulate a coolant in the coolant line to cool electrical equipment, and to be selectively connected to the battery coolant line via a first valve. A chiller is disposed in the battery coolant line, to be connected to a refrigerant line of an air conditioner via a connecting line, and to adjust a temperature of a coolant or a refrigerant by selectively exchanging heat between the coolant and refrigerant flowing into the chiller. An integrated control valve is connected to the refrigerant line and the connecting line to adjust a refrigerant flow direction and to selectively expand a refrigerant passing through the inside of the integrated control valve.
