A vehicle HVAC system includes a compressor, an interior condenser disposed on the downstream side of the compressor, a water-cooled heat exchanger disposed on the downstream side of the interior condenser, and configured to transfer heat between a refrigerant and a coolant circulating in a coolant system, an exterior heat exchanger disposed on the downstream side of the water-cooled heat exchanger, and configured to transfer heat between the refrigerant and ambient air; a refrigerant heat exchanger configured to transfer heat between the refrigerant discharged from the water-cooled heat exchanger and the refrigerant discharged from the interior condenser, and a first control valve located between the water-cooled heat exchanger and the interior condenser, and configured to allow the refrigerant discharged from the interior condenser to be directed to at least one of the water-cooled heat exchanger, the refrigerant heat exchanger, and the exterior heat exchanger.
