An air conditioning system of a motor vehicle with a refrigeration circuit and with a coolant circuit. The refrigeration circuit includes a compressor, a refrigerant-coolant heat exchanger operable as a condenser/gas cooler for the heat exchange between the refrigerant and the coolant of the coolant circuit, a first expansion device, and a first refrigerant-air heat exchanger for conditioning the intake air for the passenger compartment. The coolant circuit includes a conveying device, a first coolant-air heat exchanger for heating the intake air for the passenger compartment and the refrigerant-coolant heat exchanger. The refrigeration circuit further includes a second refrigerant-air heat exchanger for conditioning the intake air for the passenger compartment with a second expansion device located upstream in flow direction of the refrigerant. The coolant circuit is formed with a second coolant-air heat exchanger for heating the intake air for the passenger compartment.
