Regenerative heat exchanger and radial seal for use for such and method for separating gaseous media in a regenerative heat exchanger

摘要

The heat exchanger has a rotor (10) comprising a set of radially running sector walls (12). Heat accumulator chambers (19) are arranged one behind the other in a radial direction of the rotor and through-flowable by a gaseous medium. The chambers comprise openings formed in an area of front surfaces of the rotor, and a radial seal (20) is arranged at the front surfaces of the rotor, where the seal and the rotor are rotatable relative to each other. The radial seal is designed in such a manner that the seal partially covers the opening during the operation of the heat exchanger. An independent claim is also included for a method for separating gaseous medium in a regenerative-heat exchanger.
