Abstract
A heat pump system for a vehicle may include: a compressor configured to compress a refrigerant; and a heat, ventilation, and air condition (HVAC) module including an internal condenser, an evaporator connected to the compressor via a refrigerant line, and an opening/closing door configured to adjust air having passed through the evaporator to be selectively introduced into the internal condenser depending on a cooling mode or a heating mode of the vehicle. The heat pump system may also include: a heat-exchanger connected to the internal condenser via the refrigerant line; a first expansion valve provided in the refrigerant line between the heat-exchanger and the evaporator; a first connection line; a chiller provided in the first connection line so as to adjust the temperature of a coolant by exchanging heat between the refrigerant and the coolant introduced selectively; and a sub-heat-exchanger provided in the refrigerant line.
