Abstract

The invention relates to 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 ofthe 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. The invention also relates to a method for operating the air-conditioning system.

Description

technical field [0001] The invention relates to an air-conditioning system for air-conditioning the passenger compartment of a motor vehicle, said air-conditioning system having a refrigerant circuit and a coolant circuit. The refrigerant circuit has a compressor, a refrigerant-coolant-heat exchanger which can be operated as a condenser / gas cooler, a first expansion mechanism and a first refrigerant-air- A heat exchanger, wherein the refrigerant-coolant-heat exchanger is used for heat transfer between the coolant and the refrigerant of the coolant circuit. The coolant circuit consists of a conveying device for circulating and rolling the coolant, a first coolant-air-heat exchanger for heating the supply air for the passenger space, a second coolant-air-heat exchanger and a refrigerant - Coolant - heat exchanger. [0002] The invention also relates to a method for operating an air conditioning system. Background technique [0003] In motor vehicles known in the prior art, ...
