A pressure exchanger for transmitting pressure energy from a first fluid flow to a second fluid flow includes a housing having an entry and an exit for the first fluid flow and an entry and an exit for the second fluid flow. A rotor arranged in the housing includes a multitude of channels which extend radially distanced to a rotation axis of the rotor. The rotor is arranged to the entries and exits in a manner such that the channels, on rotation of the rotor, in each case in an alternating manner, connect the entry for the first fluid flow to the exit for the second fluid flow, and the entry for the second fluid flow to the exit for the first fluid flow, and with a drive motor via which the rotor may be driven in rotation, and with setting means for changing the rotational speed of the rotor. |
