Mayer, E.E.Mayer2022-03-082022-03-082002https://publica.fraunhofer.de/handle/publica/305350NOVELTY - The wall element (1) has at least one heat exchange plate (2). The heat exchange plate has a number of ventilation apertures (3). Air is passed over one side of it, some of which passes through the apertures, to which a filter (4) is fitted. At least two such elements with at least two air inputs (5) are combined to enable the air input of one element to be independent of that of the other so that the temperature of each workplace can be controlled individually. USE - For temperature control of rooms in buildings without forced ventilation. ADVANTAGE - Temperature and air renewal can be controlled without acoustic or thermal load.de608624690patent1997-19747565
