摘要： Disclosed is a heat pump system for a vehicle, providing for selective heat-exchanging heat energy generated from a coolant with a coolant upon condensing and evaporation of the coolant to control an internal temperature of the vehicle using the heat-exchanged coolant of a low temperature or a high temperature. The heat pump system adjusts a temperature of a battery module by using one chiller that performs heat exchange between a refrigerant and a coolant and improves the heating efficiency of the vehicle using a waste heat of an electrical component and a battery module.
