Abstract

An air-conditioning system of a motor vehicle having refrigerant circulation and coolant circulation. Refrigerant circulation comprises a compressor, a refrigerant-coolant heat exchanger operable as condenser/gas cooler for heat transfer between the refrigerant and the coolant, a first expansion element and a first refrigerant-air heat exchanger for conditioning the inflowing air for the passenger compartment. Coolant circulation is developed with a conveying device, a first coolant-air heat exchanger for heating the inflowing air for the passenger compartment, a second coolant-air heat exchanger and the refrigerant-coolant heat exchanger. Refrigerant circulation also includes a second refrigerant-air heat exchanger, operable exclusively as evaporator. Upstream of the second refrigerant-air heat exchanger in the direction of flow of the refrigerant, a second expansion element is disposed. The second expansion element and the second refrigerant-air heat exchanger are disposed within a first flow path. A method for operating the air-conditioning system.
