1. A thermal system for conditioning a supply air for a passenger compartment and for cooling components of a drive train of a motor vehicle, having a coolant circuit, the thermal system comprising:
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 an evaporator;
a second refrigerant-to-air heat exchanger operated as a first evaporator with an upstream first flow control device;
a heat exchanger operated as a second evaporator with an upstream second flow control device;
a third refrigerant-to-air heat exchanger operated as a condenser/gas cooler for heating the supply air for the passenger compartment as well as a third flow control device, which are formed between the compressor and the first refrigerant-to-air heat exchanger, wherein the third flow control device is formed downstream of the third refrigerant-to-air heat exchanger in a flow direction of a refrigerant, wherein the second refrigerant-to-air heat exchanger with the upstream first flow control device is disposed within a first flow path and the heat exchanger with the upstream second flow control device is disposed within a second flow path, each of which are formed to extend from a first branch-off point to a junction point, wherein the first flow control device is formed as a second branch-off point from which a main flow path and a bypass flow path of the first flow path are each formed to extend to the junction point, the second flow control device is formed as a junction point and a third flow path is formed to extend from a third branch-off point to the second flow control device, wherein the third branch-off point is disposed between the third refrigerant-to-air heat exchanger and the third flow control device.
