    摘要: An embodiment heat pump system of a vehicle includes a first cooling device including a battery module and a first line for circulating a coolant, an air conditioner unit including a compressor, an internal condenser, a main heat exchanger, a first expansion valve, and an evaporator that are interconnected through a refrigerant line for circulating a refrigerant, and a chiller connected to the first cooling device through the first line, connected to the refrigerant line through a first connection line, and configured to adjust a coolant temperature through heat-exchanging a selectively introduced coolant with the refrigerant. The air conditioner unit further includes a second expansion valve, a first valve, a second valve, a second connection line, a third connection line, and a fourth connection line.

    摘要: A heat pump system for a vehicle, capable of heating up or cooling a battery module by use of a single chiller in which a refrigerant and a coolant exchange heat, simplifying the system, includes: first and second cooling apparatuses; and a battery module, wherein a main heat exchanger provided in an air conditioning 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 therethrough, and a refrigerant passing through the main heat exchanger is selectively condensed or evaporated depending on a vehicle mode through mutual heat exchange with the coolant supplied from one of the first coolant line and the second coolant line, or the coolants supplied through the first and second coolant lines, respectively.
