Heat exchanger for air streams in living space ventilation, in which air streams are arranged rotation symmetrically over longitudinal axis of heat exchanger and a part of one air flow is reversible in its direction with each air channel

摘要

Heat exchanger in which two air streams (1,11) are arranged rotation-symmetrically over longitudinal axis (3) of heat exchanger. Heat exchanger has a rotating body (20) with many air channels (31). A taken up part of one of the air stream is reversible in its direction with each air channel to be able to be supplied in both or one of the leading away air streams.
