Heat pump system for vehicle

Abstract

A heat pump system for a vehicle may include a battery cooling line that is connected with a battery module and in which coolant moves; a chiller that is connected with the battery cooling line through a first connection line to adjust a temperature of coolant by selectively exchanging a heat of a refrigerant and coolant injected therein and that is connected with a refrigerant line of an air-conditioner device through a second connection line; an electric unit device cooler including a radiator and a first water pump that are connected through a cooling line to circulate coolant for cooling a motor and an electronic unit and that is selectively connectable with the battery cooling line and the first connection line through a first valve; and a bypass line selectively connecting the second connection line and the refrigerant line through a second valve provided in the refrigerant line.
