1. A device for distributing air, comprising:
at least one housing, wherein:
the at least one housing has an air inlet opening and a plurality of air outlet openings,
the plurality of air outlet openings is located on different sides of the at least one housing,
at least two fixed displacement elements are arranged in an interior of the at least one housing,
the at least two displacement elements each having at least one cutting plane that is configured as a cutting plane of a trumpet-shaped hollow cylinder widening along a longitudinal axis of the at least one housing,
the at least two displacement elements are rotationally symmetrical and configured as trumpet-shaped hollow cylinders conically widening along the longitudinal axis of the at least one housing,
the at least two displacement elements are spaced apart from an inner wall of the at least one housing such that air flows around the at least two displacement elements, and
the device is configured such that air flows through the at least two displacement elements along the longitudinal axis and the air exits an innermost displacement element in a central area of the innermost displacement element.
