HEAT PUMP SYSTEM FOR VEHICLE

Abstract: a heat pump system for a vehicle, which has the great advantage of improving air conditioning efficiency, enabling most of an air cooled condenser to be reduced compared to a conventional condenser, and reducing cost and a package size. a heat pump system for a vehicle comprises a refrigerant line circulating through a compressor, an outdoor heat exchanger, an expansion means, and an indoor heat exchanger in which refrigerant circulates through the indoor heat exchanger and exchanges heat with air discharged thereinto; a first cooling water line which circulates through an engine, an engine radiator, and a heater core in which cooling water circulates through the heater core and exchanges heat with air discharged thereinto; and a second cooling water line circulating through electric components and an electric radiator, which includes a valve part for connecting or separating the first cooling water line and the second cooling water line.
