Abstract
An embodiment of the present invention provides a vehicle heat pump system including a compressor configured to compress and circulate a refrigerant, a condenser configured to condense the compressed refrigerant, a first expansion valve configured to expand the condensed refrigerant, an evaporator configured to evaporate the refrigerant expanded by the first expansion valve by allowing the refrigerant to exchange heat with a coolant, a cabin cooler configured to cool a vehicle interior by allowing the coolant having passed through the evaporator to exchange heat with air, and a radiator configured to allow the coolant for cooling an electrical component to exchange heat with outside air, in which the coolant having passed through the radiator flows into the evaporator in a heating mode.
