1. A heat pump system for a vehicle, the heat pump system comprising:
an electrical component cooling device including a radiator and a first water pump that are provided in a first line, and circulating a coolant in the first line to cool at least one electrical component provided in the first line;
a battery cooling device including a second water pump and a battery module that are provided in a second line, and circulating the coolant in the battery module;
an indoor heating device including a third water pump and a heater that are provided in a third line to heat a vehicle interior by use of the coolant;
an indoor cooling device including a fourth water pump and a cooler that are interconnected through a fourth line to cool the vehicle interior by use of the coolant;
a centralized energy (CE) device in which, to supply the coolant to the indoor heating device and the coolant to the indoor cooling device, thermal energy generated during condensation and evaporation of a refrigerant circulating in a refrigerant line is exchanged with the coolant to control a temperature of the coolant; and
a chiller which is connected to a refrigerant connection line connected to the refrigerant line, is provided in a fifth line connected to the first line and the second line through a first valve and a second valve, respectively, and controls a temperature of the coolant by heat-exchanging the selectively introduced coolant with the refrigerant,
wherein the second line is selectively fluidically-connectable to the first line connected to the radiator through the second valve,
wherein a condenser included in the centralized energy device is selectively fluidically-connectable to the first line or the second line through a third valve to condense the refrigerant supplied through the refrigerant line through heat-exchange with the coolant provided in a sixth line through which the coolant flows, and
wherein a first end portion of the third line is selectively fluidically-connectable to the sixth line through a fourth valve provided in the sixth line,
wherein the first line is provided with a first branch line selectively fluidically-connectable to the sixth line through the first valve,
wherein a second end portion of the third line is connected to the sixth line at a position at which the sixth line and the first branch line cross, and
wherein the sixth line is connected to a radiator connection line through the fourth valve so that the sixth line is selectively fluidically-connectable to the radiator by operation of the fourth valve.
