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.

Abstract: A device for the heat exchange between a first fluid and a second fluid, in particular for a refrigerant circuit of an air conditioning system for treating the incoming air of a passenger compartment of a motor vehicle comprising at least one first row and one second row which are each implemented of tubes for conducting the first fluid, the tubes being disposed in parallel and spaced apart from one another and, with respect to one another, such that the second fluid flows sequentially around the rows in a direction of flow. The tubes are disposed such that second can flow in parallel around the tubes. Rows are each implemented with an inlet and an outlet for the first fluid and spaced apart from one another. Between rows a gap is implemented in each instance. A method for operating the device is also provided.

Abstract: An air conditioning system of a motor vehicle with a refrigerant circuit for operation in a refrigerator mode and a heat pump mode. The refrigerant circuit includes a primary circuit with a compressor, a heat exchanger for heat transfer between the refrigerant and the surroundings, an expansion element and a heat exchanger for heat transfer from the intake air being conditioned for the passenger compartment to the refrigerant, and a first flow path. The flow path extends from a branching point between the compressor and the heat exchanger to an opening and includes a heat exchanger for heat transfer from the refrigerant to the intake air being conditioned for the passenger compartment. The heat exchanger is situated in a flow direction of intake air of the passenger compartment after the heat exchanger.

Abstract: A climate control system of a motor vehicle having a refrigeration circuit and a coolant circuit. The refrigeration circuit includes a compressor, a refrigerant-coolant heat exchanger operable as a condenser/gas cooler for heat exchange between the refrigerant and the coolant of the coolant circuit, and at least one first refrigerant-air heat exchanger for conditioning intake air for the passenger compartment having a first expansion element upstream in a flow direction of the refrigerant. The coolant circuit includes a conveyor device, a first coolant-air heat exchanger heating the intake air for the passenger compartment, and the refrigerant-coolant heat exchanger. A refrigerant-air heat exchanger for exchanging heat between the refrigerant and ambient air is provided. The refrigerant-air heat exchanger is arranged downstream of the first refrigerant-coolant heat exchanger in the flow direction of the refrigerant. An expansion element is upstream of the refrigerant-air heat exchanger in the flow direction of the refrigerant.

Abstract: A heat-exchanger including a device for separating oil from a coolant-oil mixture and cooling the oil and cooling and/or liquefying the coolant. The heat exchanger features a first area cooling and/or liquefying the coolant, and a second area cooling the oil. The heat exchanger further features at least two manifolds. The first area of the heat exchanger features flow channels guiding the coolant, and the second area of the heat exchanger features flow channels guiding the oil. The flow channels extend between the manifolds. Each of the flow channels has a respective outside flooded by a heat-absorbing fluid.
