The present invention relates to a thermal system (1, 1a, 1b, 1c), in particular a thermal management system, for controlling the inflow air for a passenger compartment of a motor vehicle and for cooling components of a powertrain of an automobile. The system (1, 1a, 1b, 1c) is configured to operate as a compressor (3), a condenser / gas cooler and an evaporator and includes a first refrigerant-air-heat exchanger , A second refrigerant-air-heat exchanger (5) operated as a first evaporator and having a first expansion orifice (6) supported in front thereof, and a second evaporator And a refrigerant circulation system (2, 2a, 2b, 2c) having a heat exchanger (12) supported thereon. The refrigerant circulation system (2, 2a, 2b, 2c) further comprises a third refrigerant-air-heat exchanger (14) for operating as a condenser / gas cooler and for heating the room inlet air, And a third expansion orifice (15) arranged between the refrigerant-air-heat exchanger (4). The third expansion engine 15 is arranged behind the third refrigerant-air-heat exchanger 14 as viewed in the flow direction of the refrigerant. The invention also relates to a method for operating a thermal system. |
