Abstract
A heat pump system including a water-cooled type heat exchanger, which is a heat supply means, mounted on a first bypass line bypassing a second indoor heat exchanger to collect waste heat of vehicle electric devices to thereby enhance a heating efficiency of the heat pump system. The heat pump system for a vehicle includes: a branch line for connecting a refrigerant circulation line of the second indoor heat exchanger and the first bypass line with each other; a second bypass line, which bypasses an outdoor heat exchanger; and a control part that controls a flow of the indoor air to be introduced into an air-conditioning case, whereby the heat pump system can minimize influences of the outdoor air of low temperature even when the outdoor temperature is below zero, enhance the operation and the heating performance of the heat pump system by collecting waste heat of the vehicle electric devices and heat sources of the indoor air, and increase the mileage of the vehicle by minimizing operation of an electric heater.
