Abstract: A thermal system for conditioning the supply air for a passenger compartment and for cooling components of a drive train of a motor vehicle, in particular a thermal management system. The system has a refrigerant circuit with a compressor, a first refrigerant-to-air heat exchanger for transferring heat via ambient air, which is formed to be operable as a condenser/gas cooler and evaporator, a second refrigerant-to-air heat exchanger operated as a first evaporator with an upstream first flow control device as well as a heat exchanger operated as a second evaporator with an upstream second flow control device.

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 system for air-conditioning air of a passenger compartment and for heat transfer with drive components of a motor vehicle. The system has a refrigerant circuit and a coolant circuit. The refrigerant circuit is formed with a compressor, a first refrigerant-coolant heat exchanger operated as a condenser/gas cooler, a refrigerant-air heat exchanger operated as an evaporator for conditioning supply air of the passenger compartment with an upstream expansion element, and a second refrigerant-coolant heat exchanger operated as an evaporator for heat transfer between a coolant for tempering the drive components of the motor vehicle and the refrigerant with an upstream expansion element, and with a bypass flow path around the heat exchangers operated as the evaporators on the low-pressure side. In addition to the first refrigerant-coolant heat exchanger, the coolant circuit has a coolant-air heat exchanger operated as a thermal heat exchanger for heating supply air of the passenger compartment.

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.

Abstract: A device for separating oil from a coolant-oil mixture and cooling the oil and cooling and/or liquefying the coolant in a cooling circuit. The circuit features a compressor and a heat exchanger positioned downstream from the compressor in the direction of flow of the coolant and a device for separating the oil. The heat exchanger features a first area cooling and/or liquefying the coolant, and a second area as a heat exchanger cooling the oil, the second area is a heat exchanger cooling the oil as an integral part of the heat exchanger. 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.
