Abstract: A heat pump system for a vehicle which uses an evaporator of an air-conditioning case for common use in an air-conditioning mode and in a heat pump mode for cooling and heating so as to reduce weight and manufacturing costs. The heat pump system can be applied without any change in structure of the air-conditioning case, and can be operated even at low temperature without any influence of outdoor temperature because the heat pump system uses waste heat of an engine so as to enhance fuel efficiency and increase heating performance and efficiency.

Abstract: A heat pump system for a vehicle, which makes refrigerant bypass an external heat exchanger and turns off a fan mounted on the external heat exchanger when temperature of the outdoor air is lower than setting temperature and the vehicle enters into an idle state in a heat pump mode, thereby continuously operating the heat pump mode even in the below zero temperature so as to keep heating performance, reducing consumption of electrical power without needing to operate an electric heater, and preventing excessive noise of a fan when the vehicle enters into an idle state in the below zero temperature.
