Heat pump system for vehicle

A heat pump system comprising:

• a valve module configured to control a flow of an interiorly introduced coolant according to a selected mode of a plurality of modes for temperature adjustment of a vehicle interior and a battery module;
• a first line connected to the valve module to selectively flow the coolant, wherein an electrical component is disposed on the first line;
• a second line having a first end connected to the first line and a second end connected to the valve module to selectively flow the coolant, wherein a radiator is disposed on the second line;
• a third line connected to the valve module to selectively flow the coolant, wherein the battery module is disposed on the third line;
• a fourth line having a first end connected to the valve module to selectively flow the coolant and a second end connected to the third line;
• a fifth line having a first end connected to the valve module to selectively flow the coolant, wherein a chiller is disposed at a second end of the fifth line;
• a sixth line having a first end connected to the first line at a position where the first line and the second line are connected, wherein the sixth line is configured to selectively flow the coolant;
• and
• a seventh line configured to selectively flow the coolant and having a first end connected to the third line at a position where the third line and the fourth line are connected;
• wherein a second end of the sixth line and a second end of the seventh line are respectively connected to the chiller such that the sixth line and the seventh line may be connected to the fifth line through the chiller;
• and
• wherein the plurality of modes comprises:
• a first mode configured to cool the electrical component and the battery module by using the coolant cooled at the radiator;
• a second mode configured to heat the vehicle interior and recollect a waste heat of the battery module;
• a third mode configured to heat the vehicle interior and recollect a waste heat of the electrical component;
• a fourth mode configured to rapidly cool the battery module by using the coolant cooled at the radiator;
• and
• a fifth mode configured to inject the coolant.
