HEAT PUMP SYSTEM FOR VEHICLE

A heat pump system for a vehicle controls a temperature of a battery module by use of one chiller in which a coolant and a refrigerant are heat-exchanged and that improves heating efficiency by recovering heat from various heat sources in a heating mode of a vehicle to use them for indoor heating, including: a valve, an electrical component cooling device, a battery cooling device, an indoor heating device, an indoor cooling device, a centralized energy device, and a chiller, wherein a condenser included in the centralized energy device is connected to the second line through the second valve to condense the refrigerant supplied through the refrigerant line through heat-exchange with the coolant and is provided in a sixth line through which the coolant flows; and a first end portion of the third line is connected to a third valve provided in the sixth line.
