HEAT PUMP SYSTEM FOR VEHICLE

A heat pump system for a vehicle may include first and second cooling apparatuses; a battery module; and a controller electrically connected to the first and second cooling apparatuses, the battery module, and an air conditioner apparatus to selectively control the first and second cooling apparatuses, the battery module, or the air conditioner apparatus according to a vehicle mode, wherein the heat exchanger provided in the air conditioner apparatus is connected to each of the first and second coolant lines to enable the coolants circulating in the first and second cooling apparatuses to pass through the heat exchanger, and a refrigerant passing through the heat exchanger is selectively condensed or evaporated depending on the vehicle mode through mutual heat exchange with the coolant supplied from any one of the first coolant line and the second coolant line, or the coolants supplied through the first and second coolant lines, respectively.
