Heat storage element for decentralized room ventilation systems with axial fan, heat storage arrangement and decentralized room ventilation system

摘要

Heat storage element (30) for decentralized room ventilation systems, which is designed to be arranged in a room ventilation device receiving, a longitudinal axis defining wall passage, namely for placement on one end adjacent to a reversibly controllable axial fan (50) and optionally adjacent to the other end side or optionally connected with a secondary heat storage element (52), characterized in that the heat storage element (30) has flow guide elements with flow guide surfaces which form a plurality of flow channels, wherein the flow guide surfaces are not aligned all parallel, but at least partially obliquely to the longitudinal axis, and that the heat storage element ( 30) is wholly or partly formed from a material and / or is constructed so that the heat storage element (30) has an increased heat storage capacity.
