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.
