The invention relates to a flow circuit system (1) for a vehicle, with a first flow circuit (10) guiding a first fluid and operable as a heat pump, and a second flow circuit (50) with a conveying device (31) guiding a second fluid, and a switching device (35), wherein in the provided flow direction of the first fluid downstream of a compressor (3) and upstream of an expansion element (15), at least one first heat exchanger (7) between the first and second fluids, wherein the second flow circuit (50) has at least two flow circuit modes, wherein in the first flow circuit mode, apart from the at least one conveying device (31) for the second fluid and the at least one first heat exchanger (7), at least one outside heat exchanger (37) which may be flowed through by the second fluid and is configured as a radiator is connected to the second flow circuit (50), and in the second flow circuit mode this at least one outside heat exchanger (37) is not connected to the at least second flow circuit (50) containing the conveyor device (31) and the first heat exchanger (7), and preferably is also a heating flow circuit. In this way more flexibility is created in the flow circuit system (1) for a vehicle.
