A heat pump system for air conditioning a vehicle, in particular an electric or hybrid vehicle, includes an air conditioning unit which has an air conditioning evaporator and a heating heat exchanger, for air conditioning a passenger compartment of the vehicle. A condenser transmits heat from a refrigeration circuit into a coolant circuit, and a chiller transmits heat from the coolant circuit into the refrigeration circuit. The coolant circuit has two branches which are parallel to one another downstream of a low temperature cooler, namely a heating branch which can be shut off and in which the condenser and the heating heat exchanger are arranged, and a cooling branch, in which the chiller and a low temperature heat exchanger for cooling a vehicle component are arranged. The low temperature cooler, the condenser and the heating heat exchanger are connected in series with respect to one another. The heat pump system has a plurality of operating modes.
