Abstract

A device for tempering a room includes at least one component that forms a thermal accumulator and has a surface oriented towards the room. Tubes that are thermally coupled to the component can be traversed by a heating or cooling medium. The tubes are integrated into a panel that contains expanded graphite or is made of expanded graphite. The panel is in areal thermal contact with the surface of the component that faces towards the room.
