Conveyor assembly for a medium, - wherein the conveyor assembly has a conveyor line via which the medium is conveyed from a source location to a destination, - wherein the conveyor line has a conveyor section between the source location and the destination, - wherein two conveyor elements (6, 7), which are embodied as pumps, compressors, condensers or fans, are arranged in the conveyor section, - wherein the conveyor elements (6, 7) are connected in parallel with one another, - wherein the conveyor elements (6, 7) are controlled by a respective flow controller (12, 13), - wherein a target flow value (F*) which is uniform for both flow controllers (12, 13) and an actual flow value which is uniform for both flow controllers (12, 13) are supplied to both flow controllers (12, 13), - wherein the flow controllers (12, 13) calculate a respective manipulated variable (S1, S2) for the respective conveyor element (6, 7) on the basis of the target flow value (F*) and the actual flow value using a respective control algorithm (C1, C2), - wherein the conveying device has a changeover device to which the target flow value (F*) is supplied, - wherein the changeover device is embodied such that only one of the two conveyor elements (6, 7) is controlled according to the manipulated variable (S1, S2) of the associated flow controller (12, 13) at each time, while the other conveyor element (6, 7) is not actuated, - wherein the changeover device is embodied such that, if the target flow value (F*) falls below a lower changeover threshold, it suppresses the actuation of the one conveyor element by the one flow controller and releases the actuation of the other conveyor element by the other flow controller so that the medium flows solely via the other conveyor element as long as the target flow value (F*) remains above a minimum value and below an upper changeover threshold, and - wherein the changeover device is embodied such that, if the target flow value (F*) exceeds the upper changeover threshold, it suppresses the actuation of the other conveyor element by the other flow controller and releases the actuation of the one conveyor element by the one flow controller, so that the medium flows solely via the one conveyor element as long as the target flow value (F*) remains below a maximum value and above the lower changeover threshold. - wherein the conveyor assembly has a conveyor line via which the medium is conveyed from a source location to a destination, - wherein the conveyor line has a conveyor section between the source location and the destination, - wherein two conveyor elements (6, 7), which are embodied as pumps, compressors, condensers or fans, are arranged in the conveyor section, - wherein the conveyor elements (6, 7) are connected in parallel with one another, - wherein the conveyor elements (6, 7) are controlled by a respective flow controller (12, 13), - wherein a target flow value (F*) which is uniform for both flow controllers (12, 13) and an actual flow value which is uniform for both flow controllers (12, 13) are supplied to both flow controllers (12, 13), - wherein the flow controllers (12, 13) calculate a respective manipulated variable (S1, S2) for the respective conveyor element (6, 7) on the basis of the target flow value (F*) and the actual flow value using a respective control algorithm (C1, C2), - wherein the conveying device has a changeover device to which the target flow value (F*) is supplied, - wherein the changeover device is embodied such that only one of the two conveyor elements (6, 7) is controlled according to the manipulated variable (S1, S2) of the associated flow controller (12, 13) at each time, while the other conveyor element (6, 7) is not actuated, - wherein the changeover device is embodied such that, if the target flow value (F*) falls below a lower changeover threshold, it suppresses the actuation of the one conveyor element by the one flow controller and releases the actuation of the other conveyor element by the other flow controller so that the medium flows solely via the other conveyor element as long as the target flow value (F*) remains above a minimum value and below an upper changeover threshold, and - wherein the changeover device is embodied such that, if the target flow value (F*) exceeds the upper changeover threshold, it suppresses the actuation of the other conveyor element by the other flow controller and releases the actuation of the one conveyor element by the one flow controller, so that the medium flows solely via the one conveyor element as long as the target flow value (F*) remains below a maximum value and above the lower changeover threshold.
