Abstract: A heat pump system for a vehicle delays the change of the direction of a directional valve for a given period of time and then conducts the change of the direction of the directional valve, upon receiving the mode change signal between an air conditioner mode and a heat pump mode, thus preventing the generation of the noise and vibration caused by the differential pressure of a refrigerant.
