The present invention relates to a heat pump system for a vehicle, which comprises: a compressor for compressing and circulating a refrigerant; a condenser for condensing the compressed refrigerant; a refrigerant branching unit in which the refrigerant passing through the condenser is branched into first and second lines; and an electronic component cooled by coolant. The first line includes a first air-cooled condenser, a (1-1)^th line and a (1-2)^th line through which the refrigerant passing the first air-cooled condenser is branched. Also, a (1-1)^th expansion valve and a first evaporator for vaporizing the refrigerant expanded in the (1-1)^th expansion valve are disposed in the (1-1)^th line, and a (1-2)^th expansion valve and a chiller for exchanging heat between the refrigerant expanded in the (1-2)^th expansion valve and the coolant are provided in the (1-2)^th line. In addition, a second air-cooled condenser, a second expansion valve, and a second evaporator for vaporizing the refrigerant expanded in the second expansion valve are provided in the second line. Accordingly, heating performance increases.
